Rolls-Royce to Supply Waterjets to the UAE Navy

Posted on December 8, 2009

Rolls-Royce has announced 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.

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

Rolls-Royce currently 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 shipbuilding process. The order also includes a joystick control system that will improve the manoeuvring capability of the vessels, the company said.

The new vessels, measuring 26.5 m 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 said its 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.
