During an inspection, the company discovered that a pipeline on its Steelhead Platform was measuring more gas leaving the platform than what was arriving on shore.Nelson called this a “metering discrepancy,” but she said the company took the line out of service on April 1, as a precaution. Nelson wrote that the company flew over the area several times, but did not find evidence of a gas leak.The company was also responding to an oil leak from its nearby Anna platform on April 1 and has shut down two other oil platforms in Cook Inlet to deal with a natural gas leak that has been visibly bubbling to the surface of Cook Inlet since February. Icy and winter weather conditions have complicated repair of both lines.The line from the Steelhead platform has been emptied of natural gas and filled with seawater since April 3.The state agencies involved in the other spills in Cook Inlet acknowledged that they are aware of the situation on the Steelhead Platform, but would not comment on record about the situation.Lois Epstein is an engineer and the Arctic Program Director for the Wilderness Society. She joined calls from other environmental groups in Cook Inlet for an audit of Hilcorp’s aging infrastructure.“They are very open about their business plan, which is to take over old fields and make them profitable for the company,” Epstein said. “We need to see whether they’re cutting corners. We need to ask a lot of hard questions about their operations.”Epstein said the company should not be allowed to expand its operations in Alaska without addressing concerns about its safety record.
