Hilcorp Alaska said Monday that dive crews were working to repair a leaking eight-inch diameter natural gas pipeline in the Middle Ground Shoal area of the Cook Inlet. The leak point, approximately two inches in length, was noted to be on the very bottom of the pipeline resting on a boulder embedded in the seafloor, Hilcorp said. Following completion of the initial repair, further inspection and work will be done to permanently repair the affected segment of pipe. The line will not be returned to service until permanent repairs have been completed, the line has been pressure tested, and regulators have approved a re-start, Hilcorp said.
