Offshore vessels New Wildcat for
wind farms Ireland’s Safehaven Marine has expanded its current range of Wildcat catamarans with a 16m (50ſt) version specifically targeted to the wind farm market. Te 50ſt (16m) version will use an all-new mould
especially developed, but based on their established 36-40ſt hull design. Safehaven has used its expertise gained in building
pilot boats, which must withstand hard impacts when coming alongside large ships in rough weather, to impart the same qualities to the wind farm service support vessel, which will also have to endure heavy impacts when holding station alongside an offshore wind turbine’s boarding structure. A fendering solution at the bow will withstand hard use and provide a stable platform for transferring personnel to the wind generator. The Wind Farm Wildcat 50 features an island
wheelhouse configuration that allows easy passage up either side of the vessel and provides a spacious boarding area in the bow with a raised platform incorporating boarding railings leading to the jump off section. Crew and passenger safety has been paramount in refining the design. The main cabin provides for 12 passengers in
aircraſt style seating running lengthways. A central helm position features the same wrap around design that has proved popular with coxswains on pilot vessels, providing a comfortable, focused environ- ment which is essential when holding station. Sleeping accommodation consists of four berths in
each hull. Te area also provides additional storage area for equipment and spares. Te galley is incorpo- rated into the forward port cabin, with the heads situated starboard. Safehaven’s designs are fully customisable to the customer’s specific operational requirements and alternative cabin configurations are possible. Te Wildcat’s flush aſt deck provides a clear loading
area and is serviced by a 2000kg liſting capacity HIAB crane on the aſt quarter. Te well deck is cleared with numerous scuppers and the engine removal hatch arrangement is of a design refined over the years on other Safehaven workboats, providing full engine access and removal capabilities whilst remaining fully watertight. Side access doors provide easy boarding when alongside and double up as rescue zones in an emergency. A dive platform is fitted across the transom above the bridge deck with steps down to waterline access from each hull. An aluminium hydraulic dive platform design refined for numerous Wildcat 40 dive vessels gives
12
safe access to and from the water for divers. Te new Wildcat 50 will be powered by either
Scania D12 or D16 engines, with other manufacturers’ options also available, powering either conventional stern drive or jet drive. Te hull design will enable operational speeds of some 25kts, or 30kts sprint. Te Wildcat 50 design is also suitable as a Class 6,
70 passenger vessel, crew transfer and offshore work boat. Safehaven Marine is currently building two Interceptor 55 pilot/patrol vessels for the UK Port of Southampton as well as a second pilot vessel for the UK Port of Portland.
Work boats Shin Yang delivers
boat for Malaysia Malaysian ship management firm Ajang Shipping recently took delivery of a versatile maintenance workboat from Shin Yang Shipyard in Miri, Sarawak, Malaysia. Ajang Haidah is a 75m x 20m vessel with a moulded depth of 6.5m and a 5m design draught. Te new Conan Wu & Associates-designed vessel
is powered by a pair of 16-cylinder main engines of Cummins KTA50-M2 design, each developing 1800bhp at 1900rpm. Te engines turn fixed-pitch four-blade 2100 x 1512m/m propellers through Reintjes WAF664 gears with ratios of 5.044:1. Tis enables the vessel to achieve a speed of 11kts. Ajang Haidah has three Cummins KTA19DM1-
powered generators, each rated for 360kW at 50Hz. Te emergency generator set is a Cummins 6CTA8.3DM-powered 150kW generator. A 210hp Cummins 6BT5.9 engine powers the vessel’s fire pump. An 815hp Cummins VTA28DM engine generates power for the work boat’s bow thruster. Deck equipment onboard Ajang Haidah includes
a 10tons anchor windlass, a 5tons capstan and four-point mooring winch rated at 40tons. Te vessel
Ajang Haidah has been fitted with a 45ton crane and life rafts for her large complement (Credit: Shin Yang Shipyard Sdn Bhd).
