Jensen, Vigor Collaborate on SF Fireboat

By Mark Edward Nero

Crowley Maritime Corp. subsidiary Jensen Maritime has been selected to provide detail production engineering and construction management on an 88-foot by 25-foot Super Pumper NFPA Type II Fireboat for the San Francisco Fire Department. Jensen completed the fireboat contract-design for the city in 2012.

Vigor Industrial is slated to build the vessel at its 27-acre facility in Seattle. Due out in late summer 2015, the state-of-the-art workboat is expected to operate in the San Francisco Bay, San Pablo Bay and the Pacific Ocean within five miles of shore and the adjoining inland waterways.

The vessel is planned primarily for pumping, firefighting, rescue, emergency medical services and patrol. It will feature CBRNE (chemical, biological, radiological, nuclear, explosives) detection capabilities, as well as SCBAs (self-contained breathing apparatus) and local air supply ports to keep crews safe.

It was designed in accordance with NFPA 1925, the National Fire Protection Association’s standard detailing requirements for the construction of new marine fire-fighting vessels, and the American Bureau of Shipping’s rules for building and classing steel vessels less than 90 meters (295 feet) in length.

The boat will have two fire-fighting modes, according to Jensen. In normal mode, it will be able to pump 18,000 GPM of water at 150 PSI through two 3,000-GPM and two 1,500-GPM deck monitors and two 1,500-GPM under deck monitors and 18-by-3-inch and 10-by-5-inch manifolds.

In super-pumper mode, it will be able to pump 6,000 GPM of water at 150 PSI through the forward monitors, according to Jensen, and 8-by-3-inch manifolds and 6,000 GPM of water at 300 PSI through 10-by-3-inch and 10-by-5-inch manifolds.

“We have developed a good working relationship with Jensen,” San Francisco Fire Chief Joanne Hayes-White said in a statement. “They have designed a state-of-the-art, multi-operational vessel for us and we are looking forward to getting our new fireboat into the San Francisco Bay.”
