Engine Room, Machinery and Electrics
Engines are flexibly mounted Mercedes Benz OM 355 6-cylinder diesels rated at 240 bhp at 2,200 rpm with ZF type BW55G reversing gearboxes. Engine hours are approx 15,650 (Jan 2008). These give her a max speed, under ideal conditions, of around 18 knots.
Engine cooling is achieved by fresh water via either “keel cooling” to external coolers mounted in recesses in the bottom shell port and starboard amidships or by heat exchangers located outboard of each engine.
The drive is through an intermediate shaft with two flexible couplings to a conventional tail shaft. Profiseal type stern tube seals are fitted at the inboard ends of the stern tube. Main engine exhausts are water injected and run aft to the transom above the waterline. Access to the installation is very good.
Two 600 litre mild steel self levelling tanks are provided which are located at the forward end of the engine room port and starboard. The fuel levels are indicated by sight glasses with self closing valves at the lower end. The tanks are vented to atmosphere at the engine room casing sides. Drain cocks are fitted in sumps under each tank.
Fuel tanks purged: March 2007
The bilge pumping system consists of suctions with strainers from forward accommodation, engine room, aft accommodation and steering compartment bilges. These suctions are controlled by a valve chest on the starboard side of the engine room. The forepeak is drained via local cock into the forward accommodation.
A 24 volt DC system is installed serving engine starting, navigation, domestic lighting and pumping. A switchboard with fuses for all main circuits is located on the engine room after bulkhead.
A 230v 50Hz AC system is also provided with circuit breakers below the main switchboard. Shorepower is introduced via a Philippi TTR 2000 Galvanic Isolator. Each main engine has a belt driven alternator providing battery charging.
