The main propulsion engine is a flexibly mounted, naturally aspirated DAF DK1160 6 cylinder diesel engine with a continuous rating of 192 bhp @ 2200 rpm. It is mounted on high level bearers and there are aluminium floor plates on either side. It consumes about 4 litres per hour when cruising at a vessel speed of about 8/10 km/hr and 1200 rpm engine speed. Engine hours completed to date are under 5000. It is started by two heavy duty 12v 135 a/h starter batteries connected together to provide a 24v supply. It transmits power through a close coupled Newage PRM hydraulic reverse and 3/1 reduction gearbox via a cardan shaft and flexible coupling to a 60 mm dia stainless steel tailshaft and a 850mm dia 3 bladed manganese bronze propeller. A calorifier exchanges heat from the engine cooling water to provide domestic hot water when cruising or from two 220v electric immersion elements switchable between 0.5kw and 6kw as required in 0.5kw increments.  Both generators are situated in a separate compartment forward. They are started by two 12v 100 a/h starter batteries, one provides a 12v supply for the small engine whilst the two are connected together to supply 24v to start the larger engine. The Mitsubishi SL3L2-63SG generator engine is contained within a soundproof housing and drives a 10kva Newage alternator. It is used for general ships services whereas the large DAF 615 generator engine driving the 57kva Newage alternator is usually only used for supply to the Bow Thruster and Hiab deck crane. If, for example, you wanted to heat your domestic hot water tank quickly using the full 6kw immersion heater setting, then you would also need to start this bigger engine. All engines can be started and stopped remotely from the wheelhouse control panel.A Flojet 24v, Hydrophore unit provides domestic hot and cold water pressure, 17 l/min @ 3.5 bar. The Victron SKYLLA 24/50 charger is used to charge the domestic batteries and the main engine starter batteries. When cruising both set of batteries are charged by the engine mounted 80amp alternator. A Victron ATLAS 24v/300w inverter provides an ac supply for computer, printer, TV, Hi-Fi etc. There are three sockets provided for this power supply. The ship is fully centrally heated with radiators even in the engine room and generator room/chain locker.   A diesel oil fired Kabola B17 19.7kw boiler provides the heat source for the central heating system. This runs on red diesel as do the generator engines supplied from separate tanks as red diesel can not be used for propulsion. Red diesel is currently half the price of white.The engine room contains the domestic battery bank, above which are storage shelves for an extensive array of spares for all mechanical and electrical items. The 380v electric motor driven hydraulic pump for the HIAB deck crane is also in this space whereas the calorifier, Kabola boiler and inverter are situated in another space aft of the engine room bulkhead. The engine room also has the central heating red diesel tank and domestic water tank on each side. | |||||||||||||||||||||
