The Svitzer Merlin concentrates on general port collection work and recycling of waste from ships at the port of Milford Haven. She is a twin screw, pontoon style, shallow draft work vessel and with a small superstructure and wheelhouse on the portside aft, her large clear deck space across the bow will accommodate 12 waste ‘skips’ and several pallets.
The vessel is propelled by twin Doosan KEMD 196TI 320BHP manually operated diesels engines, each driving conventional contra-rotating propellers via KGDMT 170H gearboxes at 3.42:1 reduction. John Deer generators with a capacity 60Kva supply power at 415 volts 3 phase at 50 Hz.
A TMC BS300 M4 knuckle boom crane with a lifting capacity of 2152 kg at a radius of 12.08 metres is installed. An electrically driven bent axis piston pump with a rated capacity of 67lpm @ 280 bar supplies the crane at full load. The hydraulic system has a three way electrically actuated diverter valve to enable switching from crane to windlass or to the hose reel operation.
Separate from the crane/windlass and hose reel hydraulic system there is a standalone load sensing piston pump driven from the main engine and this provides the 5 tonne tugger winch 67lpm @ 210 bar with the engine speed at 1500 rpm and controlled from the aft deck.
On the hull, fendering consists of a single run of 89mm half section heavy wall pipe, fitted along the length of the vessel port and starboard at deck edge, and is fully welded and sealed. Half section heavy wall pipe chevrons are fitted underside of side deck fender and light waterline port and starboard. The bow is fitted with heavy push knees protected with ‘D’ section rubber fender and the forward deck is protected with bulwarks around the bow and extending down the forward deck on both port and starboard sides.
