Brian Gremillion and his wife seek recovery for damages arising from a back injury that he incurred while transferring a piece of heavy equipment from a crewboat onto a shoreside housing barge. The plaintiffs premise their causes of action upon the Jones Act, 46 U.S.C.App. § 688, and general maritime law. They claim that Gremil-lion was a seaman and thus entitled to the special remedies incident to such status. However, as a threshold matter we are called upon to determine whether an unconventional floating structure is a vessel. If it is, a different measure of damages may flow to Gremillion and his wife, assuming of course that he satisfies the remaining preconditions of seaman status. 1 Concluding, however, that Gremillion was not assigned to a Jones Act “vessel” and that the plaintiffs have failed to frame an actionable maritime negligence claim against the barge owner, we affirm the summary judgment.
*291 I.
Gremillion was employed by Gulf Coast Catering Company (Gulf Coast) as a maintenance man on a quarterboat barge that was chartered to an oil company for the purpose of housing some of its offshore workers. 2 His duties involved the care and upkeep of power generators and other equipment on the Q/B MINDY. He alleges injury to his back while assisting co-employees in transferring a 300-pound ice machine from a crewboat onto another quar-terboat barge, the Q/B BARBARA, during low tide in Timbalier Bay, Louisiana.
The ice machine and quarterboat barges at issue in this case are all owned by Doerle’s Quarterboats, Inc. (Doerle’s), which has no employees. Gulf Coast, a sister corporation of the owner, supplies the personnel to perform all operational and maintenance functions for the barges.
The barge to which Gremillion was assigned, the Q/B MINDY, had been towed to its Timbalier Bay location about six months prior to the accident, partially sunk into a shoreside mudbank, and affixed by lines to a dock. The barge has no self-propulsion capability, no radar, and, aside from navigational lights, no navigational apparatus. It is not registered as a vessel with the Coast Guard and is used exclusively as a stationary housing facility in shallow coastal and inland waters. During the course of Gremillion’s assignment on the Q/B MINDY, the barge was never refloat-ed for transportation to a new site, although it was moved off station a few months after his injury.
The Gremillions filed this action against the employer, Gulf Coast, seeking the ancient maritime remedy of “maintenance and cure” as well as Jones Act damages. They also prosecuted a general maritime negligence claim against Doerle’s, maintaining that the barge owner breached the warranty of seaworthiness with respect to the Q/B BARBARA, the barge on which the injury occurred, because of an allegedly faulty cleat. The plaintiffs also assert that Doerle’s owed a duty to supervise the activities of the independent contractor, Gulf Coast. 3
The district court granted summary judgment in favor of all defendants. It found the Q/B MINDY not to be a vessel within the meaning of the Jones Act. That being so, the plaintiff never attained seaman status, and the Jones Act and maintenance-and-cure claims against Gulf Coast and its excess insurer were pretermitted.
As a consequence of the Q/B MINDY’s nonvessel status, and Gremillion’s consequent nonseaman status, the unseaworthiness claim under general maritime law against the barge owner was also foreclosed. Further, the court concluded that the residual negligence claim against Doerle’s for lack of supervision could not be maintained, since barge owners generally have no obligation to protect the employees of independent contractors, such as Gulf Coast, and none of the exceptions to this rule was implicated by the facts of this case.
On appeal, the Gremillions argue that the district court’s legal conclusion regarding the Q/B MINDY’s nonvessel status under the Jones Act is at odds with this circuit’s maritime jurisprudence. They emphasize that the barge was capable of being moved easily, was involved in commerce, and possessed other attributes of Jones Act vessels, such as navigational lights, life preservers, and sleeping quarters. They suggest that any dissimilarity between the quarterboat here and a conventional vessel
*292
can be explained by the barge’s “special use” nature, reminiscent of the mobile drilling platforms and barges in
Hicks v. Ocean Drilling & Exploration Co.,
In response, the defendants argue that the Q/B MINDY is not a vessel, since it lacks most of the attributes associated with conventional vessels (e.g., engines, bilge pumps, navigational equipment, and Coast Guard registration). They emphasize that Gremillion was not injured while the Q/B MINDY was being moved and, further, that the quarterboat does not qualify as a “special use” vessel since it cannot be compared fairly to the deep-sea mobile work platforms that attained vessel status in Hicks and Gray. They assert that the Q/B MINDY is not designed for purposes of navigation and commerce; rather, its primary function is to provide housing in the inland waterways, and its transportability is purely incidental, not necessary, to its commercial mission. The fact that the Q/B MINDY may be floated and towed about the waterways should not change its non-vessel status, we are told, because the barge was never moved off location during Gremillion’s tenure.

In reviewing a summary judgment on appeal, circuit courts apply the same standard of review as the district courts.
Moore v. Mississippi Valley State Univ.,
The question of whether a claimant is a seaman is generally a factual determination.
See Barrett v. Chevron, U.S.A., Inc.,
B.
“The existence of a vessel is a ‘fundamental prerequisite to Jones Act jurisdiction’ and is at the core of the test for seaman status.”
Daniel v. Ergon, Inc.,
As a general principle, where the vessel status of an unconventional craft is unsettled, it is necessary to focus upon the “purpose for which the craft is constructed and the business in which it is engaged.”
Blanchard v. Engine & Gas Compressor Servs., Inc.,
In light of this bias favoring traditional craft, it is not surprising that we look to whether a given structure maintains or possesses (1) navigational aids, (2) lifeboats and other life-saving equipment, (3) a raked bow, (4) bilge pumps, (5) crew quarters, and (6) registration with the Coast Guard as a vessel.
See Bernard,
Structures need not lack all of the above-mentioned attributes to be deemed nonves-sels.
See Ducrepont v. Baton Rouge Marine Enters., Inc.,
Nevertheless, exotic craft may qualify as vessels, especially if frequently navigated, or if exposed to the perils associated with maritime service, or if injury occurs during ocean transport. In fact, we have stated that “a structure whose purpose or primary business is
not
navigation or commerce across navigable waters may nonetheless satisfy the Jones Act’s vessel requirement if, at the time of the worker’s injury, the structure was actually engaged in navigation.”
Bernard,
Our decisions in this area instruct, however, that as a matter of law certain dry docks and floating work platforms will not qualify as Jones Act vessels. 8 A survey of this caselaw demonstrates three common attributes for nonvessels:
(1) The structure is constructed to be used primarily as a work platform;
(2) the structure is moored or otherwise secured at the time of the accident; and
(3) although the platform is capable of movement, and is sometimes moved across navigable waters in the course of normal operations, any transporta *294 tion function is merely incidental to the platform’s primary purpose.
Daniel,
We conclude that the quarterboat barge in this case shares sufficient traits with the family of fixed platforms and floating work barges previously denied vessel status to qualify as a nonvessel for purposes of the Jones Act. We recognize that the Q/B MINDY was easily transportable; nevertheless, the significance of its transportation function is purely incidental to its primary mission of providing living facilities to workers in relatively shallow waterways. It does not transport cargo or passengers, it is not designed for navigation, it was not engaged in navigation at the time of the injury, and there is no evidence to suggest that the Q/B MINDY ever provided housing on the open sea unattached, directly or indirectly, to an appurtenance of the shore.
Significantly, the Q/B MINDY’s motive power was provided externally through towboats, as it had no engines, rudders, or navigational equipment (except lights). It also was not registered with the Coast Guard as a vessel. In weighing all the factors that this court deems relevant to vessel status, the conclusion is inescapable that the Q/B MINDY is a nonvessel for purposes of the Jones Act. 9
The plaintiffs’ reliance upon
Hicks, Robi-son,
and
Gray
for purposes of securing vessel status for this shoreside housing barge is misplaced. Those cases did not concern shoreside quarterboat barges but deep-water oil and gas platforms, which embody materially different attributes from the Q/B MINDY, and which are exposed to the hazards of the open sea. The quarterboat barge was also not directly engaged in any drilling or exploration activities. Further, we have recently stated that
“Hicks
is no longer the controlling standard” in vessel status, since its broad language has been narrowed considerably through cases such as
Bernard
and
Hemba. Johnson,
Accordingly, the district court properly held that as a matter of law the shoreside quarterboat barge in this case did not qualify as a Jones Act vessel, as the craft fairly falls within the family of nonvessels styled “floating work platforms.” Recovery of damages thus is not available to Gremillion as a seaman. Finding that the remaining negligence claims raised herein on appeal lack merit, 11 we AFFIRM.
Notes
. For a scholarly discussion of seaman status, see Engerrand & Bale, Seaman Status Reconsidered, 24 So.Tex.L.J. 431 (1983).
. The quarterboat barge at issue in this case has two decks and serves as a floating hotel for 40-60 personnel. It is designed to service oil companies working in inland waterways and shallow offshore areas. Among other things, the barge provides messing, sleeping, and recreational facilities. Lacking self-propulsion, however, the craft is usually towed to a desired location and "spudded down” on one side to the seafloor, with the other side fixed, directly or indirectly, to a bank (There were only two spuds, both on one side.). Despite advertisements that emphasized the barge's blue-water capability, there is no evidence to suggest that the Q/B MINDY ever operated in the open sea to provide housing for offshore workers.
. Albany Insurance Company was joined as a defendant because it serves as the excess-liability insurer for both Gulf Coast and Doerle’s.

. We are aware that the Q/B MINDY arguably satisfies seven of the nine factors for vessel status set forth in our recent opinion in
Johnson v. ODECO Oil & Gas Co.,
. See also Beer, Keeping Up with the Jones Act, 61 Tul.L.Rev. 379, 398-99 (1986) (criticizing this court’s pronouncements on vessel status as extending to small man-made islands and other inapposite objects).
. Since Gremillion failed to establish seaman status and, further, was not even assigned to the Q/B BARBARA, his unseaworthiness claim against the barge owner is untenable.
