AMHS Ferry Visits Bellingham Bay Shipyard

Approximately $7.4 million worth of work was performed on the 235 ft. (71.6 m), 250-passenger Alaska Marine Highway (AMHS) ferry Leconte by Bellingham Bay Shipyard (BBS). Taking about six months to complete, the work consisted of SOLAS upgrades and a repowering.

BBS was responsible for the repowering, which included the implementation of a pair of new low-NOx, 2,500-hp EMD diesels supplied by Valley Valley Detroit Diesel, plus two gensets from NC Power Systems that were comprised of CAT 3412 diesels driving 435 kW generators. Concurrently, a new switchboard from Harris Electric was installed by Sound Service Marine, who also implemented a new PA/telephone system from Hose-McCann that was integrated into the general alarm system.

Major maintenance work was performed on Leconte's tail shafts, port intermediate shaft and rudders, with machining completed by Machinists, Inc. A drive train alignment check and vibration analysis were subsequently accomplished by Diehl Engineering.

Regarding SOLAS upgrades, new structural fire protection and a new ventilation system with ducting fabricated and installed by Ershings were implemented.

Working further to meet SOLAS requirements, BBS installed new Schat- Harding davits for the Ambar fast rescue boat, along with means of rescue (MOR) platform. BBS also blasted and repainted the vessel, from its keel to upper deck prior to is return service to Alaska.
