With a total of ten monitors, each of the two identical fireboats is able to throw more than 40,000 gallons of water per minute. The water jets reach a height of up to 236 feet and a distance of up to 580 feet.<\/p>\n
The vessels are currently being built by the Foss Maritime shipyard in Seattle. Delivery to the Long Beach port authority is scheduled for spring 2014 and autumn 2014 respectively.<\/p>\n
Both vessels have an overall length of 108\u2019, a beam of 35\u2019 and a draft of 14\u2019. They are designed for an operating speed of 13 knots. The design is based on the Voith Water Tractor principle and has proven its worth in the Port of Los Angeles.<\/p>\n
The fireboats will be equipped with two Voith Schneider Propellers VSP 26GII\/165 AE45 each in the forward half of the vessel. The relatively short VSP blade length of 5.4\u2019 makes it possible for the fireboats to enter shallow areas of the port without compromising manoeuvring safety. The vessels can therefore also support onshore firefighting.<\/p>\n
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\u00b0 panoramic view. Two diesel engines, each with a power of 1,350kW, drive the VSP.<\/p>\n
Two of the total of four fire pumps are driven by the diesel engines which supply propulsion power to the VSP. When fighting a fire, the VSP propulsion power is limited to approximately 25%. The remaining 75% is available to the fire pumps as pumping power. This allows the fireboats to be positioned fuel efficiently,using the VSP while at the same time increasing the vessels’ pumping power without requiring additional engines.<\/p>\n
As the VSP pitch can be altered, the fireboats can operate efficiently and safely under all operating conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
