Excel LNG tanker suffers propulsion loss off Alaska

The 135,000 cbm Excel LNG tanker experienced last week a loss of propulsion due to a failed engineering gasket while inbound to Cook Inlet, Alaska.

Coast Guard Sector Anchorage said it has issued an order for the vessel to remain anchored in Kachemak Bay near Homer after the 908-foot, Belgium-flagged vessel experienced a loss of propulsion on Monday.

The Excel was examined by Coast Guard inspectors from Marine Safety Detachment Homer, Tuesday, who conducted a Port State Control annual exam and verified the engineering gasket was replaced, according to a statement by the U.S. Coast Guard.

While preparing to get underway Wednesday, the vessel experienced an automated engineering casualty and canceled its voyage until a Bureau Veritas classification surveyor could arrive and verify the engineering casualty was fully resolved. After arriving aboard the vessel, the class surveyor directed the vessel’s crew to test the automated engineering system and deduced that the casualty was a product of a faulty engine order telegraph; a device used on ships for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed.

Coast Guard Sector Anchorage issued another order for the vessel to remain in Kachemak Bay, according to the statement.

Friday, the vessel was allowed to continue sailing to her destination at the ConocoPhilips LNG plant in Nikiski after additional safety measures were implemented. As part of the safety measures, the tug Stellar Wind escorted the vessel from Kachemack Bay to Nikiski and a second tug, the Glacier Wind, stood by in Nikiski to assist with docking operations.

The Excel completed her voyage and moored at the ConocoPhilips pier in Nikiski at approximately noon Friday where it remains until permanent repairs are verified by the class surveyor and Coast Guard inspectors, the statement added.
