TWIN-HULLED FIRE FIGHTING BOAT FOR RIVERS AND PORTS

Increases in the transit and storage of inflammable goods on Dutch rivers have necessitated development of fast and safe fire-fighting boats. Designed and built by Shipyard Heermans & Zonen B.V. at Hedel, a prototype has recently been completed. The design had to meet a number of requirements, e.g. good course stability and manoeuvrability at all speeds, and shallow draught. The resulting design, a catamaran, is propelled by twin engines with Z drive, and hydraulically controlled propellers that can be lifted for operating in shallow waters. The firefighting pump is a Worthington Splitcase Diesel-driven pump with a capacity of 5,000 L/min at a pressure of 8 kgf/sp cm. The boat is equipped with an hydraulically operated Chubb "Slimjet" foam monitor, with a bypass foam induction system and a capacity of 22,700 L/min of foam or 3,180 L/min of water. There are two 1,000 L/min hand monitors forward and five portable fire extinguishers. To increase safety and prevent sparks, the hull is lined with a rubber fender with sprinklers below it. The steering cabin also has a sprinkler system. A ring pipeline is fitted, which can be connected to air bottles in case the service spaces have to be made gastight. Principal particulars of the boat are: Length.o.a=12.95m; Breadth, mld.=4.46m; Depth=1.65m; Draught, propellers raised under way=0.85m, 1.30m; Displacement=17tons; Speed=40km/h; Propulsion machinery=2 x Volvo Penta AQD70c/750 engines, output each: 280 hp at 2,500 rpm. A general arrangement is included. Order from BSRA as No. 49,387.
