Its first new contract, worth £15.8m, is the supply of MTU high-speed engines and a suite of waterjet propulsion systems for 17 fast patrol vessels under construction at Turkey’s Ares Shipyard for the Qatar Coastguard. The combination of Rolls-Royce MTU diesels and Kamewa waterjets will help the new craft to achieve optimum fuel economy at high speeds. In particular the A3 model of waterjet offers high performance up to speeds of around 45 knots.
Don Roussinos, Rolls-Royce President, Naval, said: “The Ares Hercules series patrol boats will be the first Qatar Coastguard craft to feature Rolls-Royce Kamewa waterjets. This is not the first project we have worked on with ARES Shipyard, but it is the largest and most important as it gives strength to our strategic decision to enter the Turkish and Qatari markets.”
The scope of supply for Rolls-Royce is extensive, with a total of 46 engines and waterjets, across three different sizes of craft. MTU 12V2000M84 diesel engines and Rolls-Royce Kamewa 50A3 series waterjets will be installed on five 24m Ares 75 Hercules patrol boats and ten of the 34m Ares 110 Hercules design. The two largest craft, the 47m Ares 150 Hercules design, will each feature three MTU Series 4000 diesels and twin 71S4 water jets with B4 boosters.
With power outputs up to 2060kW, the Kamewa A3 series deliver up to 3% better energy-efficiency compared to the earlier model. This, together with a reduced footprint on the vessel, lower weight and life-cycle costs, equates to a substantial reduction in fuel costs and CO2 emissions.
Meanwhile, the company has also been selected to supply waterjets and high speed MTU diesel engines to power two newbuild aluminium catamaran fast ferries for Chinese ferry operator Zhuhai High-Speed Passenger Ferry Co Ltd. The ferries will be some of the first to feature the highly efficient Rolls-Royce Steel S71-4 waterjets signifying the company’s growing presence in the marine market of South China.
Designed by CoCo Yachts in the Netherlands, the vessels are now under construction at the AFAI Southern Shipyard. Each ferry will be driven by an MTU 16V 4000 M70 engine delivering 2240kW, which will give the vessels a top speed of 34 knots. The first ferry is scheduled to be delivered in December this year and will serve routes in the Pearl Delta, between Zhuhai, Shekou and Hong Kong.
