Successful collaboration for Macduff
Mon, 24 March 2014
The ongoing collaboration arrangement between the Boustead Heavy Industries Group (BHIG) in Malaysia and Macduff Ship Design in Scotland, initially signed in June 2011, continues to reap rewards.
Tugowners North Tugz of Northport, Marsden Point, New Zealand has placed an order with BHIG for a 17m Macduff harbour tug of a new design. The vessel will be built at Boustead’s shipyard at Langkawi.
Macduff was originally approached by the towing company in 2012 enquiring about the successful 16mSally McLoughlin class of tug but with an increased bollard pull. Macduff produced a new design to the specific requirements of North Tugz and worked in conjunction with Boustead, which tendered the complete project.
Macduff had to satisfy the requirements of the client and Bureau Veritas [BV] in addition to meeting the stringent stability regulations of Maritime New Zealand, to ensure the new design would be suitable for operations in New Zealand waters.
With an overall length of 17m, a beam of 8m and draft aft of 3.4m, the twin screw vessel will have a pair of Caterpillar C32 main engines coupled to 2m diameter fixed pitch propellers via Twin-Disc MG5321, 6.93:1 gearboxes. The propellers will rotate within fixed high performance nozzles to achieve a bollard pull of 28 tonnes. Manoeuvrability will be enhanced with twin high performance rudders and a bow thruster with 800kg of thrust.
A Caterpillar C2.2 auxiliary generator rated at 22.5kW will be installed and the hydraulic pumps for the deck machinery, etc, will be coupled to the power take-off on each propulsion gearbox.
Tank capacities have been maximised, with 19,000 litres of fuel and 3,400 litres of fresh water to ensure a large operating window.
Deck machinery will include a towing winch on the foredeck with a line pull of 30 tonnes at 5.1m/min and a brake holding capacity of 67 tonnes, and a Mampaey quick release towhook aft with a 30 tonnes SWL. Also fitted will be a 2 tonne tugger winch and a deck crane with a capacity of 2.15 tonnes at 7.8m reach.
Thanks to careful design and layout, ergonomic efficiencies and choice of equipment, the vessel will be capable of operation by a crew of two.
This order marks the first entry into the New Zealand market for both Boustead and Macduff and was won in the face of major International competition. The working arrangement between Boustead and Macduff offers owners a unique, bespoke service combining tailored, modern designs with high quality, cost effective construction. Both companies are jointly working on a wide range of commercial designs from 12m to 85m, constructed in steel and aluminium, for various tenders.
