Rolls-Royce waterjets and MTU diesels to power 17 new patrol boats for the Qatar Coastguard

Rolls-Royce has secured a £15.8 million contract to supply Rolls-Royce MTU high-speed engines and a suite of waterjet propulsion systems for the the Qatar Coastguard’s 17 fast patrol vessels under construction at Turkey’s ARES Shipyard.

The scope of supply for Rolls-Royce Includes 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 24-meter ARES 75 HERCULES patrol boats and ten of the 34-meter ARES 110 HERCULES design. The two largest craft, the 47-meter ARES 150 HERCULES design, will each feature three MTU Series 4000 diesels and twin 71S4 water jets with B4 boosters.
“The ARES HERCULES series patrol boats will be the first Qatar Coastguard craft to feature Rolls-Royce Kamewa waterjets,” said Don Roussinos, Rolls-Royce President, Naval. “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.”
Roussinos continued, “For optimum fuel economy at high-speeds the combination of Rolls-Royce MTU diesels and Kamewa waterjets are major contributors to the enhanced efficiency and performance of these highly capable craft. In particular our A3 model of waterjet offers high performance up to speeds of around 45 knots.”
Kerim Kalafatoglu, ARES Shipyard, Chairman and Executive Director, said, “This contract for 17 craft for the Qatar Coastguard is the largest single naval export order for a Turkish shipyard. It is one of the most significant for fiber-reinforced plastic (FRP) patrol boats ever signed, and all will be built from advanced composite materials.”
According to Rolls-Royce, with power outputs up to 2,060kW, the Kamewa A3 series deliver up to 3 percent 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, the manufacturer said.
