Updates with Transocean comment in eighth paragraph.) 
     Nov. 15 (Bloomberg) -- BP Plc can’t use  Transocean Ltd.’s insurance coverage to pay costs related to the 2010  oil spill in the Gulf of Mexico, a judge in New Orleans ruled.
     BP filed claims with Transocean’s carriers last  year, seeking access to $750 million in coverage under multiple  policies. Lloyd’s of London, along with other excess underwriters, and  Ranger Insurance, Transocean’s primary insurer, opposed the claims,  contending the rig owner’s contract with BP didn’t provide such  coverage.
     The carriers owe no duty to pay claims or defense costs to BP, U.S. District Judge Carl Barbier said today.
     “The court finds that BP, under the drilling  contract, assumed responsibility for Macondo well oil release pollution  liabilities,” Barbier said in a 42-page ruling. “Because Transocean did  not assume these liabilities, there is no additional insurance  obligation in favor of BP for these liabilities.”
     The Macondo blowout and the explosion that  followed killed 11 workers and set off the worst offshore oil spill in  U.S. history. The accident and spill led to hundreds of lawsuits against  London-based BP and its partners and contractors. The lawsuits over  economic losses and personal injuries have been combined before Barbier.
                          Co-Defendants
     The lawsuits also name as defendants Transocean,  the Switzerland-based owner and operator of the Deepwater Horizon  drilling rig that exploded and sank; Houston-based Halliburton Co.,  which provided cementing services to the well; and Cameron  International, which provided blowout-prevention equipment.
     BP’s minority partners in the well, Anadarko  Petroleum Corp. and Mitsui & Co.’s Moex Offshore LLC unit, were also  sued. Anadarko and Moex had joined BP in seeking coverage from  Transocean’s insurance.
     Brian Kennedy, a spokesman for Transocean, said  the company was “pleased with the outcome.” He declined to comment  further. “We will let the court’s decision speak for itself.”
     Scott Dean, a BP spokesman, had no immediate comment on the decision.
     BP had agreed in its contract with Transocean  that the rig’s owner wouldn’t be responsible for any pollution that  originated below the surface of the land or water from spills, leaks or  discharges, Lloyd’s argued in court papers. “Because liabilities BP  faces for pollution emanating from BP’s well are from below the surface  and from BP’s well, those liabilities are not within the scope of the  additional insured protection,” Lloyd’s said in a 2010 filing.
                      Pollution Liability
     The underwriters asked Barbier to rule that BP  wasn’t entitled to pollution liability coverage under the Transocean  policies.
     “BP wants to ignore traditional risk allocation,”  George Gilly, an attorney for Transocean’s excess carriers, said at a  Sept. 16 hearing before the judge.
     BP is entitled to coverage as an additional  insured even though it isn’t named in the insurance policies, company  lawyer Allan Moore said at the Sept. 16 hearing.
     “Nobody disputes BP is an additional insured,”  Moore told Barbier. “You should enter a declaratory judgment in BP’s  favor on that point.”
     BP can tap into the Transocean policies for  coverage of pollution liabilities under Texas law, the company argued in  court papers. “The scope of BP’s insurance rights is determined by the  insurance policies themselves, not by the drilling contract,” BP said in  a Sept. 7 filing.
                        Drilling Contract
     “BP has the status of an insured for some  purposes,” Barbier said in today’s ruling. “BP would have the court stop  here and grant its motion: the drilling contract’s insurance provision  provides that BP is an ‘insured.’”
     “The scope of Transocean’s insurance obligation  in the drilling contract determines the scope of additional coverage  available to BP,” Barbier said.
     The drilling contract “allocates to Transocean  liabilities for pollution originating on or above the surface of the  water,” Barbier said. “The Deepwater Horizon Incident entailed a  subsurface release; thus, Transocean did not assume pollution  liabilities arising from the incident.”
     The insurance disputes by Lloyd’s and Ranger are  combined with other spill-related lawsuits in In Re Oil Spill by the Oil  Rig Deepwater Horizon in the Gulf of Mexico on April 20, 2010,  MDL-2179, U.S. District Court, Eastern District of Louisiana (New  Orleans).
