Two more tugs for FairplayVessel & ROV News // July 28, 2000
The main tasks of the newbuildings will be harbour and deepsea towage. However, the tugs are fitted for fire-fighting and salvage work as well.
Two Schottel propellers in Kort-Nozzles will produce a bollard pull of 66t and a speed of 13.5kt or 11kt in reverse.
The bow thruster produces a thrust of 2.8t.
Two nine-cylinder main engines of 2,750hp each and three auxiliary diesel engines supply the required electrical power.
The newbuildings have a length overall of 34.85m, a breadth of 10.90m and a draft of 5.20m.
Unlike most tugs, the newbuildings have a bulbous bow and a so-called "deadwood". This specialised shaping of the hull has been developed during extensive tank tests, and guarantees the stern driven tugs a very high level of course stability when workingastern as a reverse tractor.
With a double drum winch fore and aft (Ulstein Brattvaag SLM 63-2Ts), the ships are equipped both for harbour and deepsea towage.
For offshore work, the spacious aft-deck gives sufficient space for equipment and spares or 20ft container. Fenders all around the ships' hulls provide a high level of safety offshore.
The Palfinger crane with which they are equipped can lift 1.8t at an outreach of 11.4m.The bunker capacity of 240m3 provides an operational radius of approximately 15 days.
The fire fighting equipment is according to FiFi1, which means that the fire monitors deliver each up to 1350m3 water or foam per hour at 120m or 45m.
The classification of the newbuildings is undertaken by GL, with the notation GL+ 100A5 M E Tug + MC E Aut and corresponds with the rules of the SeeBG and the German Lloyd.
