    LIPEZ, Circuit Judge.     This appeal arises out of an
    incident on the South Boston Waterfront, where a large military
    transport vessel, the FISHER, unexpectedly spilled over 11,000
    gallons of fuel next to Boston Harbor.         Ironshore Specialty
    Insurance Company ("Ironshore"), the entity that paid the clean-
    up costs, appeals from a district court order dismissing claims it
    brought against American Overseas Marine Company, LLC ("AMSEA")
    and the United States under the Oil Pollution Act of 1990 ("OPA"),
    
    33 U.S.C. §§ 2701-2761
    , general admiralty and maritime law.   After
    carefully considering the parties' arguments and the relevant law,
    we affirm in part and reverse in part.
    I.
    The FISHER is a large, medium speed, "roll on, roll off"
    transport vessel and vehicle cargo ship.      The Military Sealift
    Command, a division of the United States Navy, owns the FISHER.
    The vessel is deployed principally to carry military vehicles and
    containerized cargo for the Department of Defense.
    In 2010, the Military Sealift Command entered into a
    contract with AMSEA, in which AMSEA agreed to crew, maintain, and
    make routine repairs to the FISHER.      In June 2014, pursuant to
    that contract, the FISHER entered a Boston graving dock owned by
    Boston Ship Repair ("BSR"), with whom AMSEA had subcontracted to
    - 3 -
    perform routine maintenance.1 No aspect of the maintenance related
    to fueling the FISHER, and only AMSEA crew members were permitted
    to conduct fuel transfers.   On July 9, while the FISHER was propped
    up on blocks within the graving dock, an oil spill occurred as a
    result of the allegedly negligent conduct of AMSEA crew members.
    More than 11,000 gallons of diesel fuel poured out of the vessel
    and into the graving dock.   To prevent the fuel from escaping into
    Boston Harbor -- and to minimize damages to the FISHER and BSR's
    graving dock -- BSR quickly acted to contain and remove the fuel.
    BSR incurred nearly $3,000,000 in costs associated with
    cleaning up the FISHER's fuel spill, which Ironshore reimbursed as
    BSR's pollution policy insurer. As BSR's subrogee, Ironshore filed
    this action in the United States District Court for the District
    of Massachusetts against AMSEA and the United States to recover
    the money it paid to reimburse BSR's cleanup costs.     Ironshore's
    three-count complaint sought (1) cleanup costs and damages under
    the OPA; (2) a declaratory judgment finding AMSEA and the United
    States to be strictly liable parties under the OPA; and (3) damages
    sounding in general admiralty and maritime law as a result of
    AMSEA's and the United States' alleged negligence.
    1  A "graving dock" is "a permanent structure on land with
    gates that allow vessels to enter and that then can be closed to
    drain out the water. In other words, it is a drydock." Vasquez
    v. GMD Shipyard Corp., 
    582 F.3d 293
    , 298 (2d Cir. 2009) (quoting
    San Francisco Drydock, Inc. v. Dalton, 
    131 F.3d 776
    , 777 (9th Cir.
    1997)).
    - 4 -
    The United States and AMSEA each filed a motion to
    dismiss   Ironshore's     OPA   claims      under     Federal   Rule   of   Civil
    Procedure 12(b)(6). AMSEA also asked the district court to dismiss
    Ironshore's negligence claims against it.                 The district court
    granted both parties' motions to dismiss in full.                  The district
    court   went   further,    however,    and    also     dismissed    sua     sponte
    Ironshore's negligence claim against the United States, concluding
    that the OPA foreclosed the option of bringing any negligence claim
    relating to oil spills under general admiralty and maritime law.
    Ironshore timely appealed, asserting that (1) the district court
    inappropriately considered documents outside the pleadings when it
    decided the defendants' motions to dismiss; and (2) it erroneously
    dismissed each of Ironshore's OPA and negligence claims.
    II.
    We review a district court's grant of dismissal under
    Rule 12(b)(6) de novo, treating as true all well-pleaded facts in
    the complaint.   Isla Nena Air Servs., Inc. v. Cessna Aircraft Co.,
    
    449 F.3d 85
    , 87 (1st Cir. 2006).
    A. Documents Outside the Pleadings
    Ironshore      argues   that,     as   a   threshold    matter,     the
    district court committed reversible error when it relied upon
    materials outside the pleadings in granting AMSEA's and the United
    States' 12(b)(6) motions to dismiss.                  Specifically, Ironshore
    challenges the district court's decision to consider the Military
    - 5 -
    Sealift Command's contract with AMSEA.    Ironshore did not include
    or append this contract to its complaint.    Rather, AMSEA and the
    United States provided excerpts of the contract to the district
    court alongside their respective motions to dismiss, and the United
    States appended the full contract to its reply to Ironshore's
    opposition to its motion to dismiss.2    Ironshore asserts that, by
    relying on the contract in its disposition of the defendants'
    motions, the district court inappropriately converted the Rule
    12(b)(6) motions to dismiss into Rule 56 summary judgment motions
    that "could not be properly resolved until the completion of
    discovery."   We disagree.3
    "Ordinarily[] . . . any consideration of documents not
    attached to the complaint, or not expressly incorporated therein,
    is forbidden, unless the proceeding is properly converted into one
    for summary judgment under Rule 56."    Watterson v. Page, 
    987 F.2d 1
    , 3 (1st Cir. 1993).     We have recognized, however, that when
    2 AMSEA also submitted a number of other documents outside
    the pleadings along with its motion to dismiss, but the district
    court only relied upon one document outside the pleadings -- the
    contract between the Military Sealift Command and AMSEA -- in its
    memorandum of decision.
    3 Ironshore has also argued that even if it may have been
    appropriate to convert the defendants' Rule 12(b)(6) motions to
    dismiss into Rule 56 motions for summary judgment, the district
    court failed to provide Ironshore reasonable opportunity to
    present any additional material pertinent to such a summary
    judgment motion as required under Rule 12(d). Because we find no
    such conversion occurred, we need not address this grievance.
    - 6 -
    considering 12(b)(6) motions to dismiss, "courts have made narrow
    exceptions for documents the authenticity of which are not disputed
    by the parties; for official public records; for documents central
    to plaintiffs' claim; or for documents sufficiently referred to in
    the complaint."      
    Id.
         Moreover, "[u]nder First Circuit precedent,
    when 'a complaint's factual allegations are expressly linked to -
    - and admittedly dependent upon -- a document (the authenticity of
    which is not challenged),' then the court can review it upon a
    motion to dismiss."        Diva's Inc. v. City of Bangor, 
    411 F.3d 30
    ,
    38 (1st Cir. 2005) (alteration in original) (quoting Alternative
    Energy, Inc. v. St. Paul Fire & Marine Ins. Co., 
    267 F.3d 30
    , 34
    (1st Cir. 2001)).
    Although      Ironshore's     complaint    does    not    explicitly
    reference the contract between the Military Sealift Command and
    AMSEA or the relationship between the two parties, the complaint
    alleges that the United States was the owner of the FISHER and
    that AMSEA was "[a]t all times material [to the dispute] the
    operator" of the FISHER.         It further alleges that AMSEA and the
    United    States    are    "responsible    parties,"       subject    to   strict
    liability under the OPA.          Because the OPA indisputably exempts
    public vessels from liability, 
    33 U.S.C. § 2702
    (c)(2), Ironshore's
    OPA claims hinge upon the question of whether the FISHER qualifies
    as   a   public    vessel.      That    question,     in   turn,     requires   an
    examination of the contractual relationship between the Military
    - 7 -
    Sealift Command and AMSEA.           Ironshore has not preserved any
    challenge to the authenticity of the contract, and, as we explain
    below,   the   contract   answers    the    determinative   OPA   question.4
    Hence, the district court did not commit a reversible error by
    considering the contract between AMSEA and the Military Sealift
    Command when it decided the defendants' motions to dismiss.
    B. Oil Pollution Act Claims
    In 1989, the oil tanker Exxon Valdez ran aground in the
    Prince William Sound on the Alaska coast, causing the largest oil
    spill at that point in U.S. history.          Congress enacted the OPA in
    response.5     See Metlife Capital Corp. v. M/V EMILY S., 
    132 F.3d 818
    , 820 (1st Cir. 1997).      Before passage of the OPA, the Clean
    Water Act "provided liability limitations for federal pollution
    removal costs associated with oil spills."          
    Id.
         The OPA altered
    the Clean Water Act framework by "impos[ing] strict liability for
    pollution removal costs and damages on the 'responsible party' for
    4 In the district court, Ironshore urged the court to exclude
    the contract from consideration when ruling on the motions to
    dismiss, noting that the motions included only excerpts of the
    contract and that Ironshore -- a nonparty -- had never seen the
    entire document. After the government subsequently provided the
    full document, Ironshore did not challenge the full document either
    by seeking leave to file a written objection or at the hearing on
    the motions to dismiss. In these circumstances, we deem waived
    any challenge to the contract's authenticity.
    5 Although we refer to the OPA's rules regarding "oil spills,"
    the statute applies equally to diesel fuel spills, such as the
    spill occurring on the FISHER. 
    33 U.S.C. § 2701
    (23).
    - 8 -
    a vessel . . . from which oil is discharged."                      
    Id.
     at 820-21
    (citing 
    33 U.S.C. § 2702
    (a)).           In turn, the OPA limits the total
    dollar amount for which a responsible party can be held liable, so
    long as that party has not committed acts of gross negligence or
    willful     misconduct.         
    Id. at 821
    .      Finally,    the      statute
    "consolidated previously established oil pollution funds into the
    Oil Spill Liability Trust Fund[,] . . . which pays claims brought
    under   the    OPA    after    they   have    first    been   presented      to    the
    responsible party, if the responsible party is entitled to a
    defense,    or    the   liability     limit    under    the   statute     has     been
    reached."     
    Id.
    In the context of oil spills occurring from a ship, the
    OPA defines a "responsible party," in part, as "any person owning,
    operating,       or   demise    chartering      the     vessel."        
    33 U.S.C. § 2701
    (32)(A).        But there is a caveat.          The OPA explicitly states
    that the statute "does not apply to any discharge . . . from a
    public vessel."         
    Id.
     at § 2702(c)(2).          Furthermore, in spelling
    out which vessels fall under the purview of the OPA, the statute
    defines the term "vessel" as "every description of watercraft or
    other artificial contrivance used, or capable of being used, as a
    means of transportation on water, other than a public vessel."
    Id. at §2701(37) (emphasis added).             The statute defines a "public
    vessel" as "a vessel owned or bareboat chartered and operated by
    - 9 -
    the United States[] . . . except when the vessel is engaged in
    commerce."     Id. at § 2701(29).
    Ironshore seeks to recover costs that it incurred when
    it reimbursed its insured, BSR, for cleaning up the diesel spill.
    All parties agree that the OPA applies to diesel spills occurring
    in graving docks such as the one owned by BSR, and no party argues
    that the FISHER was engaged in commerce when it discharged its
    fuel.   AMSEA and the United States both assert that the FISHER is
    exempt from the OPA because it was both owned and operated by the
    United States at the time of the spill and, hence, qualifies as a
    public vessel under the act.         Ironshore responds that while the
    United States was the owner of the FISHER at the time of the spill,
    AMSEA was its sole operator.        Because AMSEA crew operated the ship
    rather than government employees, Ironshore argues, the FISHER
    does not qualify as a "public vessel" under the OPA, and Ironshore
    can recover from both parties under the statute.
    Although the OPA states that vessels "owned and . . .
    operated by the United States" are public vessels, the statute
    provides no definition of the word "operated."               Nor are we aware
    of any federal court, aside from the district court in this case,
    that has been required to interpret the precise definition of
    "public vessel" under the OPA.       But the OPA is not the only federal
    statute that employs the term "public vessel."               Congress enacted
    the   Public   Vessels   Act   in   1925,    waiving   the    United   States'
    - 10 -
    sovereign immunity and allowing parties to sue the government for
    damages arising from the negligent operation of public vessels.
    See Canadian Aviator, Ltd. v. United States, 
    324 U.S. 215
    , 218-19
    (1945).     Unlike the OPA, the Public Vessels Act has provided a
    substantial       body   of   case   law   interpreting   the   term      "public
    vessels."
    In 1966, the Third Circuit faced an analogous set of
    facts to those we face here in the case of In re United States,
    
    367 F.2d 505
     (3d Cir. 1966).               There, the court had to decide
    whether a military transport tanker owned by the U.S. Navy's
    Military    Sea    Transportation     Service   and   crewed    by    a   private
    contractor constituted a "public vessel" under the Public Vessels
    Act.   
    Id. at 507-08
    .          The Third Circuit did not consider it a
    difficult question, stating, "we would have thought it too clear
    for serious argument that a ship owned by the United States and
    used as directed by the Navy for the transportation of military
    supplies is 'a public vessel of the United States.'"                 
    Id. at 509
    .
    The court flatly rejected claimants' argument that only ships
    crewed by public employees constitute "public vessels" under the
    Public Vessels Act, concluding that "government ownership and use
    as directed by the government exclusively for a public purpose
    suffice without more to make a ship a public vessel."                
    Id.
     (citing
    Smith v. United States, 
    346 F.2d 449
    , 454 (4th Cir. 1965)).
    - 11 -
    Likewise,    the   Second   Circuit   held   in   1985   that   a
    government-chartered   vessel   operated   by   a   private   contractor
    constituted a "public vessel" under the Public Vessels Act because
    "Congress understood the term 'public vessel' in the [Public
    Vessels Act] to include a vessel . . . used solely in public
    service." Blanco v. United States, 
    775 F.2d 53
    , 59 (2d Cir. 1985).
    Courts have continued to apply the same meaning to "public vessels"
    under the Public Vessels Act since the passage of the OPA.           See,
    e.g., Taghadomi v. United States, 
    401 F.3d 1080
    , 1083 n.3 (9th
    Cir. 2005); Favorite v. Marine Pers. & Provisioning, Inc., 
    955 F.2d 382
    , 385 (5th Cir. 1992).
    It is a familiar principle of statutory construction
    that "[s]tatutes which relate to the same subject matter should be
    considered together so that they will harmonize with each other
    and be consistent with their general objective scope."             United
    States v. Gray, 
    780 F.3d 458
    , 467 (1st Cir. 2015) (quoting Rathbun
    v. Autozone, Inc., 
    361 F.3d 62
    , 68 (1st Cir. 2004)).           Moreover,
    the canon of in pari materia advises that Congress generally
    intends specific words to carry consistent meaning when used in
    the same context.   Erlenbaugh v. United States, 
    409 U.S. 239
    , 243
    (1972).   When Congress opted to exempt "public vessels" from OPA
    liability, it did so against a backdrop of federal law that had
    consistently interpreted the term "public vessels" to include
    government owned ships crewed by private contractors acting on
    - 12 -
    behalf of the government.          We harbor no doubt that Congress
    intended the OPA term "public vessels" to be interpreted in the
    same manner as "public vessels" under the Public Vessels Act.            In
    the context of the OPA, we therefore adopt the sound consensus of
    our sister circuits, holding that if a vessel functioning in a
    public capacity is owned (or bareboat chartered) by the United
    States,   but   crewed   by   a   private   contractor,    such   a   vessel
    constitutes a "public vessel" so long as the private contractor is
    acting under the operational control of the United States and
    except when the vessel is engaged in commerce.6           See In re United
    States, 
    775 F.2d at 53
     ("[G]overnment ownership and use as directed
    6 Ironshore insists that the term "public vessel" should be
    interpreted more narrowly under the OPA than its interpretation
    under the Public Vessels Act because the OPA is a "strict liability
    statute," while the Public Vessels Act requires a higher burden of
    proof associated with standard negligence.     Ironshore, however,
    points to no authority -- and we can find none -- for its
    alternative interpretation. Instead, relevant legislative history
    indicates that Congress intended for the term "public vessel" to
    sweep quite broadly. In its final report on the OPA, the House
    Committee on Merchant Marine and Fisheries -- the committee with
    principal jurisdiction over the bill -- noted that       a "'Public
    Vessel' is a subclass of vessel that performs governmental
    functions for federal, state, or local units of government." H.R.
    Rep. No. 101-242, pt. 2, at 54 (1989). The only carve-out that
    the committee report envisioned was for government-owned vessels
    engaging in "commercial service," which the report defined as "all
    types of trade or business involving the transportation of goods
    or persons but exclud[ing] those vessels performing service as
    combatant-vessels."    
    Id.
       This carve-out for government owned
    vessels "engaged in commerce" also appears in the enacted statute.
    See 
    33 U.S.C. § 2701
    (29).
    - 13 -
    by the government exclusively for a public purpose suffice without
    more to make a ship a public vessel.").
    Applying this principle to the FISHER gives us little
    pause.    Although AMSEA agreed in its contract with the Military
    Sealift Command to "provide personnel, operational and technical
    support   ashore   and   afloat,    equipment,    tools,   provisions,   and
    supplies to operate, maintain, and repair the [FISHER]," the
    contract clearly established that at all times the FISHER would be
    controlled by the U.S. military.       A section of the contract titled
    "Operational Control" stipulated that the vessel would "operate in
    the worldwide service under the ultimate operational control" of
    one of five military commands.7              Moreover, a separate section
    stated that the "Military Sealift Command Headquarters" would
    exercise "Administrative Control" of the ship.
    As   part     of   its   day-to-day    operations,    AMSEA   was
    "responsible for performing scheduled and unscheduled maintenance
    and repairs, as necessary, on a 24 hour a day basis."               It held
    authority to subcontract for certain maintenance and repair work
    outside   its   own    crew's   capabilities,     though   any   subcontract
    exceeding $100,000 -- and any changes altering a subcontract by
    7 These commands, specifically, were the United States Fleet
    Forces Command, the United States Transportation Command, the
    Commander of the United States Pacific Fleet, the Commander of the
    United States Naval Forces Europe-Africa, and the Commander of the
    United States Naval Forces Central Command.

    more   than    $50,000    --   had   to    be       approved    in   advance     by   the
    government.         Furthermore,     AMSEA      was     required     to    incorporate
    specific provisions into any subcontract it executed, including
    the subcontract to use BSR's graving dock.                    Finally, at all times
    AMSEA's civilian "Master" of the ship was under an obligation to
    follow both a Navy standard operating manual and any additional
    definitive instructions from the United States Navy.
    The   strict     hierarchical           relationship        between     the
    Military Sealift Command and AMSEA establishes, as the district
    court concluded, that AMSEA crewed the FISHER under the operational
    control of the United States.           AMSEA did not lease the FISHER from
    the United States, nor was it permitted to use the vessel for its
    private gain.       Rather, all of AMSEA's work on the FISHER benefited
    the Military Sealift Command and the United States directly. Under
    the OPA, the United States both owned and operated the FISHER.
    Because    the   FISHER     is    a    military    vessel     owned     and
    operated by the United States, it qualifies as a public vessel
    under the OPA.       
    33 U.S.C. § 2701
    (29).            As such, it is exempt from
    OPA liability.

     at § 2702(c)(2).              Hence, the district court
    properly   dismissed      Ironshore's      OPA       claims    against     the   United
    States and AMSEA.

    C. Negligence Claims
    Ironshore's remaining claims sound in negligence against the
    United States and AMSEA under general admiralty and maritime law.
    We address each party in turn.
    1. Claims against the United States
    The   district   court    dismissed    all    of   Ironshore's
    remaining negligence claims brought under general maritime and
    admiralty law, concluding that the OPA supplants and preempts all
    such claims.      For this principle, the district court quoted our
    decision in South Port Marine, LLC v. Gulf Oil Ltd. P'ship, 
    234 F.3d 58
     (1st Cir. 2000), where we noted that "Congress intended
    the enactment of the OPA to supplant the existing general admiralty
    and maritime law."       
    Id. at 65
    .       However, the district court
    interpreted the holding of South Port Marine too broadly.
    In South Port Marine, a private marina filed suit under
    the OPA against a petroleum company to recover damages incurred
    after an oil spill allegedly caused by the petroleum company's
    employee.     
    Id. at 60-61
    .     The district court determined that
    punitive damages were unavailable under the OPA.          
    Id. at 61
    .   We
    affirmed    the   district   court,   concluding   that    when   Congress
    supplanted general admiralty and maritime law by passing the
    OPA -- a statute that provides no punitive damages -- it sought to
    eliminate punitive damages entirely in any case where OPA liability
    applied.    
    Id. at 65-66
    .
    - 16 -
    Although we acknowledged in South Port Marine that the
    OPA supplants general admiralty and maritime law when the OPA is
    triggered, we said nothing about the statute's effect on general
    admiralty and maritime law outside the OPA context.              Put simply,
    South Port Marine was silent regarding the OPA's effect on the
    ability of parties to sue for negligence under general admiralty
    and maritime law when a public vessel is the genesis of an oil
    spill.
    Fortunately, the statute itself is not silent.               In a
    subsection of its savings provision titled "Admiralty and Maritime
    Law," the OPA states:         "Except as otherwise provided in this Act,
    this Act does not affect . . . admiralty and maritime law."              
    33 U.S.C. § 2751
    (e).    Hence, because public vessels lie outside the
    sweep of OPA liability, any preexisting admiralty and maritime law
    that applied to public vessels before the OPA's passage survives
    its   enactment.        The     district   court   erroneously     dismissed
    Ironshore's negligence claims against the United States when it
    did so sua sponte.
    The United States argued in its brief that even though
    Ironshore's   general    admiralty     and   maritime   negligence    claims
    against the United States are not foreclosed by the OPA, Ironshore
    has either abandoned or waived those claims because it alluded
    only to Massachusetts state law claims in its opposition to AMSEA's
    motion to dismiss.      This argument is misguided.      In responding to
    - 17 -
    pretrial   motions,   Ironshore     never    had   to   assert   its   general
    admiralty and maritime law claims against the United States,
    because the United States had not moved to dismiss them.               Rather,
    as noted above, the district court dismissed those claims sua
    sponte.     Ironshore has since vigorously asserted its general
    admiralty and maritime claims against the United States in its
    briefing before us.       We do not view those claims as abandoned or
    waived.
    2. Claims against AMSEA
    Because we are reinstating Ironshore's negligence claims
    against    the   United   States,   its   claims   against   AMSEA,     cannot
    survive.    In order to explain this conclusion, we must briefly
    address the principle of sovereign immunity.
    The United States, as sovereign, cannot be subject to a
    suit unless it waives its sovereign immunity.           See Thames Shipyard
    & Repair Co. v. United States, 
    350 F.3d 247
    , 253 (1st Cir. 2003).
    The provisions of such a waiver define its scope.            
    Id.
       Ironshore
    has filed its negligence claims against the United States pursuant
    to the Suits in Admiralty Act, which includes an explicit sovereign
    immunity waiver for certain admiralty and maritime claims.8                But
    8 Under the Suits in Admiralty Act the United States waives
    its sovereign immunity "[i]n a case in which, if a vessel were
    privately owned or operated . . . a civil action in admiralty could
    be maintained." 
    46 U.S.C. § 30903
    (a); see also Thames Shipyard &
    Repair Co., 
    350 F.3d at 253
    .
    - 18 -
    the strings attached to this sovereign immunity waiver prove fatal
    to Ironshore's negligence claims against AMSEA.
    The Suits in Admiralty Act states that "[i]f a remedy is
    provided by this chapter, it shall be exclusive of any other action
    arising out of the same subject matter against the . . . agent of
    the United States . . . whose act or omission gave rise to the
    claim."   
    46 U.S.C. § 30904
     (emphasis added); see also Ali v.
    Rogers, 
    780 F.3d 1229
    , 1233 (9th Cir. 2015).      Ironshore argues
    that AMSEA should not be considered an agent of the United States
    for purposes of the Suits in Admiralty Act's exclusivity provision
    because record evidence indicates it was "acting entirely on its
    own behalf."
    This argument is misguided.   In cases filed pursuant to
    the Public Vessels Act, other circuits have held that a private
    contractor crewing a ship that qualifies as a public vessel is
    necessarily an "agent of the United States" for purposes of the
    Suits in Admiralty Act's exclusivity provision.       See Favorite
    Marine v. Marine Pers. & Provisioning, Inc., 
    955 F.2d 382
    , 388
    (5th Cir. 1992) ("As a matter of legal definition, 'agent' of the
    United States is an appropriate characterization of such a contract
    operator of a public vessel." (quoting In re United States, 
    367 F.2d 505
    , 509-10 (3d Cir. 1966)); see also 
    id.
     ("[T]he general
    statement of an agency concept . . . include[s] any instrumentality
    through and by which the public vessels are operated." (quoting In
    - 19 -
    re   United    States,      
    367 F.2d at 510
    )    (second   alteration   in
    original)).     Having already decided that the concept of a "public
    vessel" has the same meaning under the OPA and the Public Vessels
    Act (see supra Section II.B.), we conclude that contractors crewing
    a ship deemed a "public vessel" for purposes of the OPA are -- as
    a matter of legal definition -- agents of the United States for
    purposes of the Suits in Admiralty Act's exclusivity provision.
    Hence, AMSEA crewed the FISHER as an agent of the United States.
    As   such,    the   Suits   in    Admiralty     Act's    exclusivity   provision
    prevents Ironshore from advancing any claims against it.
    III.
    We affirm the district court's dismissal of Ironshore's
    OPA claims against the United States, but we reverse the district
    court's dismissal of Ironshore's general admiralty and maritime
    negligence claims brought against the United States pursuant to
    the Suits in Admiralty Act and remand those claims to the district
    court for further proceedings consistent with this opinion.                    We
    affirm the district court's dismissal of all of Ironshore's claims
    against AMSEA.      Each party shall bear its own costs.
    So ordered.
