Port of Alaska has remained open for business and been deemed safe for continued operation following Friday morning's major earthquake, according to port officials.

"The general cargo docks and trestles have been inspected and are safe for regular shipping operations," the Anchorage facility said in a news release on its website.

Officials said the quake damaged several dock lights and overhead power lines that have since been repaired and dock cranes and other equipment are ready for regular use, according to inspectors.

"There are no known injuries or petroleum leaks or spills because of the earthquake."

TOTE's 22,400-dwt ro-ro North Star (built 2003) is moored at the port, according to Vessels Value.

Upper Cook Inlet okay for shipping activity

US Corps of Engineers surveys indicate that Upper Cook Inlet shipping channels and Port of Alaska berths will support normal shipping operations, officials said.

“Port of Alaska’s resiliency through this earthquake demonstrates the value of adhering to stringent engineering and maintenance schedules and standards," port director Steve Ribuffo said.

"Unfortunately, good maintenance slows but can’t stop corrosion, and this level of performance is not sustainable for even a few more years.”

The 60-year-old port is undergoing a modernisation and expansion programme to fix its aging infrastructure.
