Rolls-Royce, the global power systems company, has won an order to supply 24 lightweight waterjets for the UAE Navy’s fleet of fast patrol boats.

The UAE Navy has ordered 12 new fast patrol boats, based on the proven Ghannatha Class fast troop transport vessel. These are currently under construction by Abu Dhabi Ship Building (ADSB), with the first due to enter service in 2012.

“There are already 150 Rolls-Royce waterjets in service across the region and this order further increases our presence in this important market. In response to this growth, and to provide in-service support for our growing customer base, we are working with ADSB to establish a waterjet service centre in Abu Dhabi,” stated Jay Dagher, Rolls-Royce Naval Marine regional manager - Middle East, North Africa and Latin America.

Each vessel will be equipped with two Kamewa FF600 waterjets, designed and manufactured by Rolls-Royce. The waterjets are fitted with interceptors to enable tighter turning capability, better stability and to reduce fuel consumption.

Rolls-Royce is currently the only company that builds interceptors on waterjets which are controlled with a waterjet control system known as the Incorporated Interceptor Control (IIC). This means that interceptors no longer need to be purchased, installed or controlled separately, translating into greater efficiency and time savings in the ship-building process.

The order also includes a joystick control system that will improve the manoeuvring capability of the vessels.

The new vessels, measuring 26.5 metres in length, are being constructed from aluminium and the waterjets will enable a maximum speed in excess of 35 knots.

Kamewa waterjets power a range of vessels from the smallest inshore craft to the largest ocean going vessels. Rolls-Royce advanced pump technology gives enhanced pulling thrust at lower speeds and the lightweight aluminium construction reduces overall vessel weight to offer higher speeds with improved fuel economy.

Waterjets give greater manoeuvrability compared with conventional propulsion systems, allowing vessels to be turned on the spot, stopped at full throttle within a few boat lengths, and even moved sideways. The absence of moving parts protruding beneath the hull also makes waterjet powered vessels ideal for operation in shallow waters and also improves safety during rescue missions.

Rolls-Royce has previously supplied FF550 waterjets and SII Kamewa waterjets to the UAE Navy.

The company supplies 70 navies with products ranging from gas turbines and diesel engines, to propulsion, motion control and electrical systems, and has a growing network of marine service facilities in 34 countries.-TradeArabia News Service
