Full Opinion (html_with_citations)

WIENER, Circuit Judge:

Petitioners Coastal Production Services Inc. (“Coastal”), Forest Oil Corporation, and ACE American Insurance Company (collectively, “Petitioners”) seek our review of an order of the Benefits Review Board (“BRB”) affirming the determination of the Administrative Law Judge (“ALJ”) that Respondent Terry Hudson (“Hudson”) is entitled to benefits under the Longshore and Harbor Workers’ Compensation Act (“LHWCA” or “Act”), 33 U.S.C. § 901 et seq. Perceiving no error in the determinations of the ALJ and the BRB that Hudson was a maritime employee who was injured on a maritime situs, we deny the petition for review.

I. FACTS AND PROCEEDINGS

In January 2001, Hudson began working as a junior contract platform operator for Coastal. He was assigned to the Saturday Island facility in Barataría Bay, Plaque-mines Parish, Louisiana.1 The Saturday Island field comprises (1) a large platform with living quarters (the “Saturday Island platform”), (2) fourteen satellite wells that are connected to the platform by horizontal subsurface piping, and (3) a sunken oil storage barge (“the Cherokee”) that is adjacent to the platform. The satellite wells pipe their production (a mixture of oil, gas, and saltwater) to the Saturday Island platform, where the components are separated. The required amount of the separated gas is re-distributed throughout the oil field for gas-lift purposes, and the remainder is piped to a Southern Natural Gas pipeline for resale. The separated saltwater is injected into disposal wells. The separated oil is first piped into holding tanks on the platform, then is periodically transferred to larger storage tanks on the Cherokee. When the Cherokee’s storage tanks are full, the oil is transferred into customers’ transport barges for delivery onshore. All oil produced from the Saturday Island field’s satellite wells is ultimately shipped ashore by transport barge.

Hudson’s job entailed several different duties. He (1) checked the satellite wells daily by “jo-boat” and was responsible for their maintenance and upkeep, (2) serviced *429and maintained the Saturday Island platform, (3) transferred oil from the platform’s holding tanks to the storage tanks on the Cherokee approximately three to four times per week, (4) performed daily inspections and maintenance of the Cherokee, including inspecting its lines for leaks, checking its gauges, and maintaining its engines, and (5) assisted in the loading of oil from the Cherokee into the transport barges when they came to pick up the oil. Hudson testified that in performing this last duty, he would place a walk-board between the Cherokee and the arriving transport barge, hook up pipelines and hoses to transfer oil, disconnect and reconnect the hoses and pipelines as the Cherokee’s holding tanks emptied, and monitor the tank levels. According to Hudson, he took part in many, if not all, of the oil transfers that occurred while he was working.

On August 11, 2001, Hudson was injured when the saltwater disposal pump on which he was working exploded.2 That pump was located on the Saturday Island platform, which is located approximately 30 to 40 feet from the Cherokee and connected to it by a permanent walkway and oil transfer pipes.

Hudson filed a claim for benefits under the LHWCA. Petitioners contested coverage, arguing that pursuant to Herb’s Welding, Inc. v. Gray,3 Thibodeaux v. Grasso Production Management Inc,,4 and Mung-uia v. Chevron USA, Inc.,5 the Saturday Island platform did not qualify as a maritime location. Petitioners also contended that Hudson did not qualify as a maritime employee because his employment activities furthered the non-maritime purpose of oil production; moreover, they argued that any job-related maritime activities performed by Hudson were minimal and not a regular part of his duties.

The ALJ ruled that Hudson satisfied both the situs and status requirements of the LHWCA. With respect to situs, the ALJ concluded that the Cherokee’s docking facility — which was used to load oil into transport barges — qualified as an “other adjoining area customarily used by an employer in loading” a vessel, and that the Cherokee and the Saturday Island platform were component parts of a single area. The ALJ distinguished the Saturday Island platform from the fixed platforms in Herb’s Welding, Thibodeaux, and Munguia on the basis of function: The Saturday Island platform and the Cherokee comprised a single facility, the maritime purpose of which is the loading of cargo (already extracted oil) onto vessels.6 *430With regard to status, the ALJ determined that Hudson met the requirements for land-based maritime employment because his assisting in the loading of oil and maintaining the loading equipment was essential to the cargo loading process. Additionally, the ALJ concluded that Hudson’s maritime activities were routine and recurring, not episodic, momentary, or incidental to his non-maritime work.

On appeal, the BRB affirmed the ALJ’s holding as to both situs and status. The BRB adopted the ALJ’s reasoning that the Saturday Island platform was a covered situs because (1) it is surrounded by navigable water and (2) functions as a facility for loading cargo (oil) onto vessels. The BRB determined that the Cherokee and the Saturday Island platform could not be classified as separate areas because they are permanently connected to each other through a system of pipes and a walkway. The BRB also concluded that Hudson’s work in loading oil into the transport barges and maintaining the pipes and equipment necessary to the loading process constituted maritime employment and that the ALJ rationally computed the amount of time that Hudson spent in the performance of these activities.

II. ANALYSIS

1. Standard of Review

Our review of the BRB’s decision is limited in scope to “considering errors of law, and making certain that the BRB adhered to its statutory standard of review of factual determinations, that is, whether the ALJ’s findings of fact are supported by substantial evidence and [are] consistent with the law.”7 “Substantial evidence is that relevant evidence — more than a scintilla but less than a preponderance — that would cause a reasonable person to accept the fact finding.”8 We review the BRB’s legal conclusions de novo.9 Although perhaps somewhat quizzical in light of the typical understanding of the difference between conclusions of law and findings of fact, we decided in Texports Stevedore Co. v. Winchester that the determination of situs by the ALJ is one of fact.10 Status *431determinations are also findings of fact, unless made under an erroneous legal standard.11

2. Analysis

For a claimant to be eligible for benefits under the LHWCA (1) his injury must occur on a maritime situs, and (2) his status must be that of a maritime employee.12 Both requirements must be met for the claimant to receive benefits under the Act.13

a. Situs

Section 3(a) of the LHWCA states that a claimant is eligible for benefits “only if the disability or death results from an injury occurring upon the navigable waters of the United States (including any adjoining pier, wharf, dry dock, terminal, building way, marine railway, or other adjoining area customarily used by an employer in loading, unloading, repairing, dismantling, *432or building a vessel).”14 As the Saturday Island platform does not meet the definition of any of the kinds of facilities specifically listed in the statute, it must qualify as an “other adjoining area” to be considered a maritime situs.

To qualify as an “other adjoining area,” the situs must be located in proximity to navigable waters (i.e., possess a geographical nexus) and have a maritime nexus — here, “customarily used by an employer in loading ... a vessel.”15 The situs need not be used exclusively or even primarily for maritime purposes, as long as it is customarily used for significant maritime activity.16 No party disputes that the Saturday Island platform adjoins navigable waters, so the geographic nexus prong of the test is satisfied; the only open question is whether it is within an area with a maritime nexus.17

At the outset, we must define the relevant area and then ask whether it is customarily used for loading a vessel or other maritime activities listed in § 3(a) of the LHWCA. There are several levels of generality that could, as a theoretical matter, be used to define the area. We could consider (1) the exact locus of the injury (the saltwater pump), (2) the Saturday Island platform, (3) the Saturday Island facility (i.e., the platform plus the Cherokee), (4) the entire Saturday Island field (i.e., the satellite wells, the gas transportation system, the platform, and the Cherokee), (5) the whole Barataría Bay, and so on. The first option is foreclosed by our opinion in Winchester:18 The last option and levels of even greater generality are obviously absurd, and we repudiated such extremes in Winchester as well.19 We assume without deciding that the entire Saturday Island field is also too extreme a level of generality.20 We are left, there*433fore, with the second and third options. This case turns on the correctness of the ALJ’s determination that both the platform and the Cherokee are part of the same “overall area” that is customarily used for loading cargo (oil).

We do not define a covered area for LHWCA purposes according to fence lines and local designations because they “are subject to manipulation for compensation purposes.”21 Instead, Winchester appears to have merged the two questions— definition of the area and connection to enumerated maritime activities — into a simple junctional inquiry. The “area” that adjoins navigable waters for purposes of the LHWCA is that area “customarily used by an employer in loading, unloading, repairing, or building a vessel.”22 Yet the Saturday Island platform, except for its storage of fully processed and produced oil (which is arguably part of the process of loading a vessel23), is itself not customarily used for loading oil onto the customers’ transport barges, which on-load the processed oil from the Cherokee for transport to shore. Instead, at least without the temporary storage tanks, the Saturday Island platform is better thought of as a processing plant functionally connected to oil production and not to the loading or unloading of cargo from vessels.24 If Win-*434Chester countenanced a strict reading of “area,” or if we were to address this issue de novo, we might end the inquiry here and conclude that Hudson was not injured on an LHWCA-covered situs. As neither is the case, however, we continue.

Winchester involved a gear room located five blocks from the gate of the nearest dock. The gear room contained “spreader bars, pallets, wire cable slings, tow motors, forklifts, etc.” that were “used by stevedores to perform the loading operation.”25 We held that an injury in the area of the gear room occurred on a covered situs. Our holding on those facts teaches that simply because a vessel cannot dock for loading and unloading at a particular area does not mean that the area is not a covered situs. It further teaches that if a particular area is associated with items used as part of the loading process, the area need not itself be directly involved in loading or unloading a vessel or physically connected to the point of loading or unloading.

Vessels were not loaded or unloaded directly from the Saturday Island platform, at least not with cargo. Rather, vessels were loaded with cargo (oil) from the Cherokee, which was directly and permanently connected to the platform (by pipes and a walkway), in close proximity to it (30 to 40 feet), and described by the employer in its operations manual as part of the same “gathering and processing” facility as the platform.26 Further, the platform was functionally integral to the Cherokee’s loading and unloading mission because the configuration of the Saturday Island field used the platform as the consolidation point for transport. If the platform were to sink tomorrow, the satellite wells could still produee/extract the oil, water, and gas mixture, but that mixture (whether or not processed and separated) could not be loaded onto vessels. The fact that the Saturday Island field could have been set up differently, perhaps with pipelines (as was done for gas), or with vessels loading the raw, unseparated product at each satellite well, or some other way, is no answer to the fact that as actually set up, the platform’s “gathering” function plays an integral role in the loading of vessels, even if its “processing” function might not. As such, the entire platform is “customarily used by an employer in loading ... a vessel.”

This conclusion is buttressed by the liberal construction we are instructed to employ in favor of LHWCA coverage,27 and the fact that whatever argument there might be about the platform’s role in loading, the Cherokee is unquestionably in*435volved in loading vessels. Covering the platform as well as the Cherokee, between which Hudson moved on a daily basis in unquestionable furtherance of the loading duties of his job (for example, to inspect the Cherokee each day), “will reduce the number of employees walking in and out of coverage”28 and further the congressional policy of eliminating “shifting and fortuitous coverage.”29

Winchester also directed us to consider the “general area” and the “overall loading process.”30 The fact that “the specific locus of the injury is not customarily used for maritime purposes even though the general area is so used” is not fatal to a finding of maritime situs.31 These instructions clearly contemplate some role for geography (i.e., proximity and interconnectedness), independent from function. The dissent implicitly acknowledges this when it repeats six times that the geographical separation of the Cherokee is relevant to the nexus determination. If Winchester only stood for a functional inquiry, the fact that a particular area is not used for maritime activities would be dis-positive. But, Winchester does not require every square inch of an area “generally” used for loading and unloading to be so used. If it did, we would have a game of hopscotch: The bathrooms in an otherwise “adjoining area” would not be covered, nor would be pavement that although clearly within the area, had not been walked on by stevedores loading and unloading a vessel.

Winchester countenanced defining a general area (a geographic notion) by its function. If a general area is customarily — not necessarily exclusively or predominantly — used for loading and unloading of vessels, all parts within it are a maritime situs. To determine whether it is fair to call a particular part of a facility “within” the “general area” used for loading and unloading, we must look both to its proximity and its interconnectedness to the loading and unloading location, along with its function.32 Simply because Winchester extended coverage to a non-proximate, non-interconnected location on the basis of function does not mean that proximity and connection play no role in our analysis.

Additional support for this proposition comes from Northeast Marine Terminal Co., Inc. v. Caputo. There, the Supreme Court addressed a facility with “two ‘finger-piers.’ ”33 One pier, located on 21st Street, “was used to berth ships for purposes of loading and unloading them.”34 Another pier, on 19th Street, and therefore presumably some distance away, “was used only for stripping and stuffing containers and storage.”35 The Court held *436that an injury on the 19th Street “finger-pier” nevertheless occurred on a covered situs because “[t]he entire terminal facility adjoined the water and one of its two finger-piers clearly was used for loading and unloading vessels.”36 This is obviously a close analogy to the Cherokee and the platform. Unlike the dissent, we cannot conclude in light of Caputo that there is not more than a scintilla of evidence that supports the situs determination by the ALJ and BRB.

Like the BRB itself in this case, we also see the BRB’s decision in Gavranovic v. Mobil Mining & Minerals37 as support for this proposition. There, the BRB concluded that the situs requirement was satisfied because the manufacturing facility where the accident occurred was “used to store finished product and to load rail cars and trucks.”38 Even though Building 10 (the situs of the injury) was not used to load vessels (as the statute requires), it was “in close proximity to the docks and ... not [a] separate and distinct area[ ].”39 More to the point, the BRB said:

Although the facility at which claimants herein work is a manufacturing operation, and the building in which they were injured is not directly involved with the loading and unloading of vessels, part of employer’s business involves sending and receiving goods by barges or vessels — a distinctly maritime activity. Moreover, the geography of ... the entire facility and the building in question [are such that they] are adjacent to navigable water and to the docks where barges are loaded and unloaded.40

Again emphasizing that geography plays some role, the BRB said: “In light of the location of employer’s facility and because significant maritime activity ... occurs ... [there], we affirm ... that claimants’ injuries ... occurred on a covered situs.”41

*437On the one hand, Hudson might have been injured while on the Cherokee, which clearly qualifies as a covered situs. On the other hand, Hudson might have been injured while working on the satellite wells, which do not qualify as “adjoining area[s]” under Thibodeaux. Given the close functional and geographic relationship between a clearly maritime situs (the Cherokee) and a somewhat less clearly maritime situs (the platform), several factors we have identified support affirmance on the facts of this case.

First, we owe deference to the ALJ/ BRB’s situs determination, and they concluded that the platform was a maritime situs. Second, the LHWCA is to be construed liberally in favor of compensation. Third, Winchester deliberately selected a very broad and liberal construction of situs (a room used to store gear located blocks away from the nearest gate to a terminal and outside the property line of the port) and counseled us to do the same by inspecting the “overall loading process” and the “general area.” Fourth, we effectuate congressional policy to avoid shifting and fortuitous coverage (although, as the dissent points out, this cannot always be avoided because there must be a line somewhere) by finding that the platform, adjoining the Cherokee and functionally related to its loading purpose, is a maritime situs. Considered as a whole, these additional thumbs on the scale tip the balance in favor of affirming the ALJ/BRB’s determination that the platform qualifies as a maritime situs. Merely because one discrete portion of an area adjoining navigable waters, and part of the general loading and unloading area, is not directly used for loading and unloading (say, a food cart on a dock, or a scrubber as part of the hose connected to unload the oil), this should not create hopscotching coverage. If, as Petitioners urge, we were surgically to separate the platform from the Cherokee — and classify one as maritime and the other as non-maritime — we would do exactly that which Congress sought to eliminate with the 1972 amendments to the Act.42 We decline to slice the Saturday Island facility that finely and cause that situation.

We cannot say that the ALJ did not have substantial evidence that would permit a reasonable person to conclude that the Cherokee and the platform are in the same general area customarily used for loading vessels. Neither can we say in the alternative that functionally the platform was not actually part of the loading process (even though it also served the arguably non-maritime production purpose of separation).

The area need only “customarily” be used for loading, not exclusively or predominantly so. This is why the presence of gas pipelines from the platform to shore does not vitiate the maritime nature of the platform. Piping gas to shore is a non-maritime activity, but, again, the platform need not be used exclusively or even predominantly for maritime activities to qualify as a maritime situs. In fact, oil is the primary product of the platform and is shipped by barge, for which the platform (unlike the satellite wells) is a necessary part of the loading process in the field as configured. So, although it need not be *438the case, here the platform does appear to have a predominantly maritime use — facilitation of the loading of cargo (oil, the main product of the platform).

This conclusion is not foreclosed by Thi-bodeaux or Herb’s Welding. In Herb’s Welding, a majority of the Supreme Court expressly declined to decide whether a fixed drilling platform qualifies as a maritime situs.43 The dissent thought that the situs requirement was satisfied.44 Yet, although the majority refused to reach the issue, there are hints that even it thought a drilling platform might qualify as a covered situs.45

In Thibodeaux, we resolved that question for fixed oil “production”46 platforms in the territorial waters of Louisiana by concluding that the platform was not a maritime situs.47 The claimant in Thibo-deaux was a pumper/gauger who was injured when he attempted to repair a leaking line under the deck of the platform.48 Relying in part on the Supreme Court’s comments in Herb’s Welding, we determined that the platform did not serve a maritime purpose.49 Specifically, we noted that

Thibodeaux has pointed to no connection Garden Island Bay platform No. 276 has with maritime commerce that distinguishes it from the platforms in [Herb’s Welding or Munguia]. Oil is not shipped from the platform. Although personal gear and occasionally supplies are unloaded at docking areas on the platform, the purpose of the platform is to further drilling for oil and gas, which is not a maritime purpose.50

Because the oil production platform in Thi-bodeaux did not serve any maritime purpose, we held that it was neither a “pier” nor an “other adjoining area” as defined by the Act.51 The dissent questions our reliance on Thibodeaux’s, statement that the platform in that case was not involved in oil shipment (i.e., the loading or unloading of cargo). Far from being an isolated or superfluous statement, that observation is the linchpin of the distinction between Thibodeaux and Caputo: The platform served no maritime purpose precisely because it was in no way involved in loading or unloading a vessel. The structure of the quoted material makes that clear: Drilling is contrasted with shipment (which we construe to mean loading or unloading).

Unlike the platform in Thibodeaux, there is no evidence that the Saturday Island platform is now or ever was involved in drilling or extracting hydrocar*439bons,52 and it has an independent connection to maritime commerce — as we have excruciatingly demonstrated above, the loading of cargo (oil) from the Cherokee, with the necessary intermediation of the platform given the configuration of the Saturday Island field, is a maritime purpose. Although there are no docking facilities on the Saturday Island platform per se, it is directly and permanently connected to the Cherokee, and it serves as a temporary holding station for the already-produced and separated oil until it is further transferred the 30 to 40 feet to the Cherokee where it is held until it can be shipped ashore by barge. Thus, the Saturday Island platform is part of the “general area” used as part of the “overall loading process” adjoining navigable waters, clearly distinguishable from the drilling (but not shipping) platform in Thibo-deaux.

Based on the foregoing analysis, we conclude that Hudson was injured on a maritime situs. As the LHWCA requires both maritime situs and status, however, our analysis does not end here. We must also determine whether Hudson’s status was that of a maritime employee.

b. Status

The Act confers maritime status on “any person engaged in maritime employment, including any longshoreman or other person engaged in longshoring operations, and any harbor-worker including a ship repairman, shipbuilder, and ship-breaker.”53 An employee may qualify for maritime status based on either (1) the nature of the activity in which he is engaged at the time of the injury or (2) the nature of his employment as a whole.54 Although the Act does not define “maritime employment,” the Supreme Court has instructed that occupations in addition to those enumerated in the statute will be covered as maritime employment if the occupation entails activities that are an integral or essential part of the loading, unloading, building, or repairing of a vessel.55 In addition, the employee’s maritime activities must be more than episodic, momentary, or incidental to his non-maritime work.56

As Hudson was not employed in any of the occupations enumerated in the statute, his work must have been integral or essential to the loading, unloading, building, or repairing of a vessel to be covered under the LHWCA. The ALJ and the BRB determined that Hudson was a maritime employee based on his responsibility for the general upkeep of the Cherokee and his facilitation of the loading of cargo (oil) into transport barges. The ALJ and the BRB also determined that these activities were not merely episodic, momentary, or incidental to non-maritime work, because they were regularly assigned to platform operators.

*440Petitioners assert that the BRB erred by concluding that Hudson was a maritime employee because the majority of his daily activities were related to servicing and maintaining oil and gas production facilities. Petitioners claim that, under the Supreme Court’s holding in Herb’s Welding, such activities are not maritime in nature and, therefore, do not qualify Hudson as a maritime employee.

In Herb’s Welding, the Supreme Court addressed whether an employee who was injured while welding a gas-flow line on a fixed offshore oil drilling platform was a “maritime employee.”57 The Court explained that “the maritime employment requirement is an occupational test that focuses on loading and unloading.”58 After determining that the employee’s work as a welder was wholly unrelated to any loading or unloading process, the Court held that he was not a maritime employee.59

We do not disagree with Petitioners’ insistence that those of Hudson’s activities that related solely to the production of oil and gas from the fourteen remote production facilities do not imbue him with maritime status. But, there was more: Unlike the welder in Herb’s Welding, Hudson was directly involved in the loading of cargo into transport barges for shipment to shore — a distinctly maritime activity. Specifically, Hudson transferred previously produced oil that had come to rest in the platform’s storage tanks to the larger tanks on the Cherokee where it awaited transport by barge (not by pipeline); he checked the Cherokee’s cargo loading lines for leaks; and he maintained its engine. Hudson also hooked up lines for transferring the oil from the Cherokee to the customer transport barges, manned the emergency shutoff during such transfers, and boarded customers’ barges to witness gauge readings. These routine, non-episodic activities are all maritime in nature and support the conclusion that Hudson’s status was that of a maritime employee.

Petitioners nevertheless contend that even if Hudson was involved in maritime activities, he failed to dedicate a sufficient percentage of his work to such activities to bestow maritime status under the LHWCA. We disagree.

The ALJ determined that, as part of his regularly assigned duties, Hudson spent approximately 9.7% of his time engaged in the above-described maritime activities.60 To arrive at this figure, the ALJ calculated the amount of time Hudson spent (1) loading oil into transport barges and (2) servicing the equipment necessary to load the oil.61 Crediting Hudson’s testimony re*441garding his participation in the oil transfers, the ALJ determined that Hudson spent a total of 22 hours transferring cargo. The ALJ also determined that, according to time sheets entered in the record, Hudson spent a total of approximately 122 hours maintaining the Cherokee and its equipment. As each of these calculations is supported by substantial evidence, we perceive no error in the ALJ’s determinations.

As for the fact that Hudson spent approximately 9.7% of his time performing maritime activities, we have never set a minimum amount of time required to qualify as a maritime employee under the Act. We have, however, upheld maritime status for an employee who spent only 2.5-5% of his employment engaged in maritime activities when those activities were part of his regularly assigned duties, as were Hudson’s.62 Thus, Hudson easily spent more than any minimum amount of time that an employee must be engaged in maritime activities to be considered a maritime employee under the Act.

III. CONCLUSION

We hold that, under the discrete facts of this case, the fixed platform in question is inseparable from the Cherokee and that together they constitute a loading facility for the transhipment of cargo by vessel. As such, the platform qualifies as a maritime situs, being an element that is essential to the maritime activity of loading cargo for transport. We also hold that Hudson regularly engaged in sufficient maritime activities to meet the status requirement of the Act. It follows that, as Hudson was injured on a maritime location and qualifies as a maritime employee, neither the ALJ nor the BRB erred in determining that he is eligible for benefits under the LHWCA. The petition for review is DENIED.

. 370 F.3d 486, 494 (5th Cir.2004) (holding that a fixed oil drilling platform is neither a "pier” nor an "adjoining area” because the platform's sole purpose is to further gas and oil production, a non-maritime activity).

. 999 F.2d 808, 813 (5th Cir. 1993) (discussing that the purpose of an oil platform is to drill for oil and gas, which is a non-maritime activity).

. The platform also served at least one non-maritime purpose, i.e., piping natural gas to shore, and the arguably non-maritime purpose of processing the mixture received from the satellite wells. Processing is probably part of "production” in the technical sense, see Production, The Dictionary of Petroleum Terms (2001) ("[T]he phase of the petroleum industry that deals with bringing the well fluids to the surface and separating them and storing, gauging, and otherwise preparing the product for delivery.”), and is probably a non-*430maritime activity because it frequently occurs onshore and has no peculiar connection to maritime activities. We flesh out a possible counterargument in note 24 infra.

It is worth noting that Herb’s Welding and Thibodeaux appear to have used "production” to mean drilling and extraction (i.e., vertical removal of the product), even though the technical definition of production seems to include separation, processing, and some storage. See Herb’s Welding, 470 U.S. at 416-23, 425, 105 S.Ct. 1421 (repeatedly describing the platform as a drilling platform, but once describing the platform at issue as a production platform); Thibodeaux, 370 F.3d at 490, 492, 494 (noting that drilling for oil and gas is not a maritime activity, but also referring to the platform as a production platform). Munguia, 999 F.2d at 809-10, also appears to have focused on platforms involved in drilling and extraction. The progenitor of all of these cases, Rodrigue v. Aetna Casualty & Surety Co., 395 U.S. 352, 352, 360-61, 89 S.Ct. 1835, 23 L.Ed.2d 360 (1969), described the platform at issue as a drilling platform and did not use the word production. It thus does not appear that mere classification of a platform as involved in “production” in the technical sense forecloses a finding of maritime situs, at least not as a matter of stare decisis. In any event, as we discuss infra notes 14-42 and accompanying text, the Saturday Island platform is also involved in the loading of vessels — a traditional maritime activity — so we need not reach this issue.

If the situs determination is supported by substantial evidence on the record as a whole, it will not be set aside by this court.” (emphases added and internal citations omitted)). The references to the situs determination and a factual determination make clear that the Winchester court was speaking of the ultimate conclusion about situs, even though that may seem like a legal conclusion.

This matter is not free from doubt, as we have said that "[w]e review the determination of LHWCA coverage by either an ALJ or the BRB as a question of law.” Boomtown Belle Casino v. Bazor, 313 F.3d 300, 302 (5th Cir.2002) (citing Hullinghorst Indus., Inc. v. Carroll, 650 F.2d 750, 753 (5th Cir. Unit A 1981) (“[W]e reject at the outset [the] contention that the Board exceeded its statutory authority in reversing the determination of the ALJ that Carroll was not a covered employee within the meaning of the Act. Under the uncontested facts, the ALJ's determination in this regard was neither a finding of fact nor a factual inference drawn from the evidence. It was a conclusion of law.”)).

There appears to be a circuit split on this question. Compare Winchester, 632 F.2d at 515, and Brooker v. Durocher Dock & Dredge, 133 F.3d 1390, 1392 (11th Cir.1998) (“Although this court reviews the ALJ’s interpretation of the LHWCA de novo, it will not set aside the ALJ's findings of fact, including its situs determination, if substantial evidence supports them.” (citing Winchester, 632 F.2d at 515)), with Jonathan Corp. v. Brickhouse, 142 F.3d 217, 221 (4th Cir.1998) ("Because the facts relating to the resolution of the situs issue are not substantially in dispute, coverage becomes a question of law which we determine de novo.” (citing Potomac Elec. Power Co. v. Dir., OWCP, 449 U.S. 268, 278-79 & n. 18, 101 S.Ct. 509, 66 L.Ed.2d 446 (1980) and Pittman Mech. Contractors v. Dir., OWCP, 35 F.3d 122, 125 (4th Cir.1994))).

The cases on which the Fourth Circuit relied deal with the deference owed to statutory constructions of the LHWCA by the BRB. In particular, Potomac Electricity Power Co. v. Director, OWCP, 449 U.S. at 278 n. 18, 101 S.Ct. 509, stands for the proposition that no deference is owed to BRB statutory constructions because the BRB is not a policymaking agency. This decision by the Supreme Court is not, however, in direct conflict with our classification of the situs determination as one of fact, not law. The Court simply concluded that the BRB’s statutory interpretations of the LHWCA are owed no deference.

Were we writing on a clean slate, it is unclear how the ultimate conclusion by an ALJ or the BRB about whether a locus satisfies the situs requirement of the LHWCA is a question of fact, particularly when the facts underlying the situs determination are not in dispute. We are nevertheless bound by Winchester, which was a unanimous en banc determination of this precise issue by this court, there being no contrary intervening precedent on this exact issue by either the Supreme Court or this court en banc.

. Although "adjoining” connotes "lying next to” or "beside,” we observed in Winchester that "adjoining” can also be defined as "neighboring.” 632 F.2d at 514. Additionally, Webster's Dictionary defines "adjoining” as "touching or bounding at some point or on some line: near in space.” Webster’s Third New International Dictionary 27 (2002). Adopting the broad definition of the word "adjoining,” we conclude that the Saturday Island platform adjoins navigable waters because is it located in and has direct contact with navigable waters. This interpretation conforms with our conclusion in Winchester that "[t]o instill in the term [adjoining] its broader meaning is in keeping with the spirit of the congressional purposes [of the Act].” 632 F.2d at 514. For these same reasons, the Cherokee too adjoins navigable waters.

In fact, the platform and the Cherokee are in navigable waters. We nevertheless treat fixed platforms as islands for almost all purposes. See, e.g., Rodrigue v. Aetna Cas. & Sur. Co., 395 U.S. 352, 360, 89 S.Ct. 1835, 23 L.Ed.2d 360 (1969). Visually, it is best to conceive of the facility (the platform and the Cherokee) as onshore because we treat the Saturday Island facility as "land.” This helps to understand how the facility "adjoins” navigable waters.

. Id. at 514 ("Nevertheless, outer limits of the maritime area will not be extended to extremes. We would not extend coverage in this case to downtown Houston.”).

. We may assume this without deciding it because to pick this level of generality reduces to the choice between options two and three. If the "overall area,” Winchester, 632 F.2d at 516, includes the satellite wells and the gas transportation system, we would end up with what might be termed a “mixed coverage situs” under the apportionment principle found in cases like Bianco v. Georgia Pacific Corp., 304 F.3d 1053 (11th Cir.2002). Cases like Maraney v. Consolidation Coal Co., 37 BRBS 97 (2003) and Jones v. Aluminum Co. of America, 35 BRBS 37 (2001), deal with situations in which there are clearly covered and clearly non-covered parts of an overall *433area. The satellite wells and the gas transportation system are, after Thibodeaux, clearly not covered sections of the overall area. But, Hudson's injury did not occur at either of those places. Accordingly, we would still have to answer whether only the Cherokee or the platform plus the Cherokee are covered parts of the overall area.

. We note that storage of fully processed oil in the storage tanks on the platform can quite plausibly be understood to be part of the loading process. The storage tanks hold finished cargo and adjoin navigable waters; they are directly and permanently connected by pipes and a walkway to the point at which the vessel actually receives the cargo (which also adjoins navigable waters and is no more than 30 to 40 feet away); and, operation of the storage tanks is necessary for a vessel to be loaded, given the cargo storage configuration of the Saturday Island facility: If no oil flows from the platform's storage tanks to the Cherokee, no oil is available for a vessel to load. This is quite distinguishable from the dissent’s example of storage facilities at most production plants. Those storage facilities (presumably) lack a geographical nexus to navigable waters, (presumably) are not directly and permanently connected to the shipping terminal, and (presumably) operation of the storage facilities is not the only way to get products to the shipping terminal and then loaded onto a vessel given the set-up of the loading system. If those presumptions are wrong, it is unclear why it would be absurd to treat such storage facilities as part of the loading process. We also note that the satellite wells, inasmuch as they are unarguably involved in extraction/production only (and not in processing and storage), do not serve a loading purpose (unlike storage and transfer), and are therefore not part of the loading process, even though they may be necessary to loading in the “but for” sense.

.Although we do not base our decision on it, it is at least arguable that a facility integral to the conversion of material into cargo suitable for maritime transport, such as the platform’s separators, has a role in loading a vessel. It would, of course, be possible to ship the mixture of oil, gas, and water on vessels without first processing it, but that would likely prove to be more expensive (the yield of marketable product per shipment would dramatically decrease because each shipment would include useless saltwater) and would also deprive the producer of an economical method of gas-lifting the field (instead, gas would have to be transported out to the field after processing onshore). We seriously doubt whether a particular process used to facilitate the economical loading of vessels must be necessary to loading a vessel before it may be considered part of the loading process (that conclusion would lead to absurd results wholly inconsistent with our cases), but the conceptual line between production/process*434ing of hydrocarbons and loading/unloading a vessel is somewhat blurry in the case of the separation facility on the Saturday Island platform. As we do not need to resolve this issue today, we do not.

Although we shied away from employers’ descriptions of the relevant area in Winchester, we did so to prevent employers from manipulating boundaries in a unilateral effort to determine the coverage area. When an employer has defined an area as part of a facility also used for loading and unloading, however, that concern is less pressing and we have no trouble taking account of that description. In any event, Winchester only said that "fencelines and employers’ designations will not ... end the factual inquiry.” 632 F.2d at 515 (emphasis added).

. The dissent questions how we can conclude that the Cherokee and the platform constitute a single situs, but also conclude that the satellite wells and the platform, which have pipes connecting them, are not. In the first instance, we note that even if the wells are interconnected with the platform, they are not proximate to it. Second, the satellite wells are not interconnected to the platform in the relevant way. The Cherokee and the platform have a walkway that allows, with a few steps, an employee to move between them, bringing concerns about shifting and fortuitous coverage into play. The satellite wells have no such connection to the platform; they must be accessed by boat. Accordingly, although physically connected, they are not connected in the relevant manner.

Harbor Construction Co., 26 BRBS 97 (1992). In Mele-rine, the BRB noted that the dock was

separate and distinct from the mill. The steel mill is located one-quarter mile from the dock area, separated by a road and a levee, and materials are transported by truck from the mill to the dock. The [ALJ] found that no conveyors or other loading apparatus linked the two areas .... The mill is used solely for the manufacturing of steel products [,]

a clearly non-maritime activity. 26 BRBS at *3. In Stroup, the shipping bay at issue (attached to the structure at issue in Melerine) was "1/4 to 1/2 [of a] mile from the docks and the Mississippi River. Further, the 'A' bay is separated from the River by a public road and a levee and is located in a building which also houses the melt shop, the roll mill, and another shipping bay.” 1998 WL 461480, at *1. In Dickerson, the site of the accident, a

phosphoric acid plant[, had] nothing to do with maritime activity and its sole purpose [was] to convert the liquid sulfuric acid into phosphoric acid and store it. It has no connection to the docks by way of conveyor belt or other means. It is geographically and functionally separate from the docks.

Coal Co., 37 BRBS 97, at *6 (2003) ("In the instant case, [the location of the injury] is functionally and geographically separate from employer’s unloading/loading operations.” (emphasis added)). Jones simply recited the unsurprising proposition that "a plant that manufactures aluminum oxide is not engaged in [loading, unloading, repairing or building of vessels].” 35 BRBS at *6. Jones is per*437haps the best support for the dissent’s conclusion, because it is not clear how geographically distinct the manufacturing and loading sites of the facility were. In light of Caputo and Winchester, along with the bulk of the BRB's other cases, however, we cannot justify using that ambiguity in Jones to reach a contrary result in this case.

. 142/1465 = 0.097. The ALJ determined that Hudson worked a total of 1465 hours during his employment with Coastal. Because of an arithmetical error, the ALJ mistakenly credited Hudson with 142 total hours of maritime-related activity instead of 144. Under the correct mathematical calculation, Hudson actually spent 9.8% of his time engaged in maritime activities. 144/1465 = 0.098.

.Petitioners also advance that the ALJ erred by including the amount of time Hudson spent maintaining and servicing the equipment on the Cherokee. The ALJ determined that the maintenance of the Cherokee was necessary and essential for the proper loading and transfer of the oil into transport barges. As employees who are injured while maintaining or repairing equipment essential to the loading or unloading process are covered by the LHWCA, the ALJ did not err by including this time in its calculation.
