In 2009, GPA began provided design services for the refurbishment and repowering of theChief Seattle, one of the fire boats serving the City of Seattle. The vessel was successfully delivered in February 2013 at Vigor Marine in Everett, WA.

Under the direction of the City of Seattle’s Department of Finance and Administrative Services (FAS), GPA’s team managed the project from initiation to delivery, working closely with FAS, Vigor Marine and the Seattle Fire Department.   

The 96-foot Chief Seattle, built in 1984, replaces the Alki, built in 1928, as the city’s primary freshwater fireboat.  The overhaul extends the vessel’s service life by about 20 years.  

GPA developed contract specifications and plans and assisted the City of Seattle administrate the refurbishment of the fireboat to NFPA 1925 Type II standard.  This included a new superstructure and pilot house with an emergency command center, complete replacement of electronic navigation and communication equipment, plus an infra red surveillance system, a new medical treatment room, crew day room and head, as well as a new rescue boat and boat recovery system.

The renovation also included the replacement of three 1012 hp propulsion engine with pump drives with two 1522 hp propulsion engines, reduction gears, new shafts and propellers.  Furthermore, two 715 hp fire pump engines with four 2500 gpm pumps, new fire-fighting system with foam capability, one new motorized fire monitor, two refurbished under-wharf motorized monitors, three manual monitors and three hose manifolds were installed. Chief Seattle is now equipped with systems, engines and pumps capable of pumping 10,000 gal/min compared to 7,500 gal/min before the overhaul and can travel at a top speed of 22 knots.

The delivery completes Seattle’s fireboat fleet upgrade, which added two additional vessels in recent years, the Engine One and Leschi.

About every two years, each Seattle fireboat spends several weeks at a shipyard for repairs and maintenance.  With the third one now completed, the department can have at least one boat protecting each side of the locks in Seattle at all times, even during maintenance periods.

The renovation project adds to GPA’s high level of experience providing design and engineering services for emergency response vessels operating in various ports in the US. Such newbuild and renovation projects include fireboats for the Honolulu and Seattle Fire Departments, as well as multiple offshore vessels certified with FiFi capabilities operating worldwide for a variety of offshore clients.
