Cheoy Lee's 58m Anchor Handling Tug/Supply Vessel is a model in high demand, with six units currently under construction, all destined for operation in the Middle East. Shark 30, Cheoy Lee yard number 4969, is the first of a two ship order for a long standing customer of Cheoy Lee. The vessel will be flagged in Kuwait, and is destined to supply, support and act in the capacity of a safety vessel, for offshore drilling and workover rigs on a twenty-four hour per day basis in the Arabian Gulf. Specific duties will include the transport of fresh water, diesel oil, bulk cement, liquid mud, stores, materials and equipment, tow/move drilling and workover safety rigs, anchor handling duties, move men and materials between platforms and shore, and evacuate casualties.
The design, now well proven, originated from Singapore based naval architects Conan Wu & Associates and incorporates an all steel hull and superstructure. The vessel is constructed to ABS class with the notation ABS+A1(E) + AMS FIFI 1 Towing and Anchor Handling Services.
Shark 30 can accommodate a complement of twenty two men. All are housed in the forward part of the vessel. On the main deck level, there is one four man cabin, although this deck predominantly contains the service and recreational areas, the galley, mess rooms, sick bay and cold stores. The accommodation on the forecastle deck level includes individual cabins for the captain and chief engineer, along with three double and two four man cabins. The working deck aft is over 30m (100') long, with an area of approximately 350m2. The deck is sheathed in wood to protect the steel deck plating during anchor handling and towing operations. Deck plating in way of the towing gear is 20mm thick.
Propulsion power comes from two air start Caterpillar 3516B diesel engines each producing 2,575 hp, driving Nakashima controllable pitch propellers in nozzles via Twin Disc MGR 1727VC 7:1 reduction gearboxes. Maneuvering is enhanced by a 12tonne Schottel bow thruster directly driven by a 1,130hp Caterpillar diesel. Electrical power is developed by three Caterpillar 320kW diesel generating sets, each independently capable of supporting the ships loads. In addition, there is a 72kW back-up set that also serves as a harbour generator.
Deck winches are from MacGreggor Plimsoll, and include a 200tonne towing/anchor handling winch, 10tonne anchor windlass, two 10tonne tugger winches, and two 5tonne capstans. Towing equipment also includes Triplex towing pins and a Shark Jaw. On deck, there is also a 5tonne@6m Palfinger crane to handle the rescue boat and also for loading provisions.
With a fuel capacity of 400tonnes, the vessel has a range of 6,500n.m at the maximum speed of 12 knots. Fuel is cleaned by an Alfa Laval purification system, as is the lube oil. The vessel is also able to carry 485 tonnes of fresh water, 10m3 for fire fighting foam, 10m3 of dispersant for tackling oil spills, 210m3 of liquid mud and 4000tonnes of dry bulk.
