The incident has forced the Valdez Marine Terminal’s operator, Alyeska Pipeline Service Co., to take multiple tanks out of service, though it says there have been no impacts to oil shipments so far.
Oil and gas company Hilcorp paid federal regulators $180,500 for taking too long to inspect and repair dozens of leaks in Cook Inlet and on the North Slope.
A Hilcorp pipeline sprung a leak late in December 2016 that continued for three months.
The number of jobs in Alaska’s oil and gas industry remains relatively low after companies cut nearly a third of the workforce during the COVID-19 pandemic.
Hilcorp became the main oilfield operator in the state after it bought BP’s Alaska assets last year.
This is the first time a company other than Hilcorp Alaska has won leases in a state sale since 2015.
A leaking Cook Inlet pipeline contributed to Hilcorp’s high methane escapement, but Hilcorp’s larger methane problems are in the Lower 48.
Hilcorp’s line, which delivers fuel gas to a system of oil platforms in the inlet, sprung a leak last month.
Legislation proposed by Gov. Mike Dunleavy would allow the state to sell subsurface gas-only leases in part of Kachemak Bay so companies could drill into undersea reservoirs from miles away.
The last time the pipe leaked, in 2017, Hilcorp didn’t complete repairs for three months, citing danger from ice in the inlet.
