Propelled Fire Fighting

Voith to supply fireboats with Voith Schneider propellers, turbo couplings

Posted on August 9, 2013

Voith will provide Voith Schneider propellers and turbo couplings for two fireboats designed by Robert Allan Ltd. for the Port of Long Beach, California, U.S.A. With a water pumping capacity of more than 151 416 L/min.

With a total of 10 monitors, each of the two identical fireboats has a water pumping capacity of more than 151 416 L/min able. The water jets reach a height of up to 72 m and a distance of up to 177 m. Both fireboats will be in operation in the Port of Long Beach, where they replace the two older fireboats – Liberty and Challenger.

 Both vessels have an overall length of 33 m, a beam of 10.6 m and a draft of 4.3 m, with an operating speed of 13 knots. The fireboats will be equipped with two Voith Schneider propellers (VSP 26GII/165 AE45) each in the forward half of the vessel. The VSP blade length of 1.6 m makes it possible for the fireboats to enter shallow areas of the port without compromising maneuvering safety. The vessels can therefore also support onshore firefighting.

 For each fireboat, the Voith scope of supply includes not only two VSP, but also two 866 DTL Voith turbo couplings as well as a twin control stand unit. Its positioning in the wheelhouse is such that the captain and crew benefit from a 360 degree panorama view. Two diesel engines, each with a power of 1350 kW, drive the VSP.

 The vessels are currently being built by the Foss Maritime shipyard in Seattle, Washington, U.S.A. Delivery to the Long Beach port authority is scheduled for spring 2014 and autumn 2014, respectively.
