Portion of Nikiski dock collapses in Cook Inlet

Heavy seas reportedly collapsed a 50-foot section of the Offshore Systems Kenai dock in Nikiski.

Heavy seas caused an Offshore System Kenai (OSK) earth and fill dock, with fuel lines, to collapse, Oct. 2, 2019, resulting in the discharge of approximately 300 gallons of oil. Inspectors from Coast Guard Marine Safety Detachment Homer responded to the incident and are coordinating with the responsible party and state authorities to mitigate further pollution. The dock continues to erode, but all remaining hazardous materials have been removed. (U.S. Coast Guard courtesy photo)

A portion of the Offshore Systems Kenai (OSK) dock in Nikiski collapsed Wednesday, spilling approximately 300 gallons of diesel fuel into the Cook Inlet and prompting a suspension of operations.

“The Coast Guard is temporarily closing the north portion of the dock as a precaution to protect life and property as well as reduce further impact to the environment,” Coast Guard Captain of the Western Alaska Port Sean Mackenzie said in a Wednesday news release from the U.S. Coast Guard.

Coast Guard pollution responders from Marine Safety Detachment Homer responded Wednesday to a report that heavy seas caused a 50-foot wide section of the OSK dock to fall into the Cook Inlet. Pollution responders are working with the responsible party and state authorities to mitigate further pollution caused by the collapse. The dock continues to erode, but all remaining oil and hazardous material have been removed.

All operations on the north face of the pier are suspended until permanent repairs can be made, according to the release. Members of the public who find oil or other signs of the pollution in the area should report it to the National Response Center by calling 1-800-424-8802.
