Rolls-Royce unveil new marine TRENT 30 gas turbine

Rolls-Royce has announced the first details of the new Marine Trent 30 gas turbine, bringing Trent aero engine technology to marine customers. The gas turbine is available for service in either mechanical or electrical genset applications and will be a force in both commercial and naval marine markets - a formal launch is planned for Spring 2002. 4

Available for delivery from late 2003, the Marine Trent 30 boasts a power rating of 36MW (ISO, no loss) and is cost-effective, compared to all existing gas turbines, for all marine applications from 25MW. It is ideal for frigates, destroyers and aircraft carriers requiring high powered propulsion.

It also provides propulsion system designers with greater flexibility - a single Marine Trent 30 can replace two conventional boost turbines, saving space and reducing operating and ownership costs.

The Marine Trent 30 has 80 per cent commonality with the Trent 800 aero engine which has transformed civil aerospace achieving:

• 99.9 per cent dispatch reliability
• More than two million flying hours since it entered service in 1996
• A 45% market share of total Boeing 777 aircraft orders to date.

This latest marine engine is part of Rolls-Royce's strategy of developing its core gas turbine technology expertise across a range of markets. The Marine Trent 30 package is lightweight and compact. The total package, including enclosure and auxiliaries, weighs less than 26,000kg, giving it a market-leading power to weight ratio in its class. Its dimensions are 8.9 metres long, 3.5 metres wide and 4.3 metres high.

Dr Saul Lanyado, Rolls-Royce President - Marine, said: "The Marine Trent 30 brings leading-edge, proven, aero gas turbine technology to the marine marketplace - marking a step-change in performance, simplicity and maintainability."

Its modular construction, a key element of all Rolls-Royce gas turbine technology, combines reliability with maintainability. The Marine Trent 30 can be replaced within 12 hours of engine cool down and is easily transportable by land, sea or air for module separation on the dockside or at the repair and overhaul base.

The gas turbine is supported by customer-dedicated Rolls-Royce teams, backed by a global sales, repair and overhaul network. Its two spool compressor design offers reduced start times, good balance retention and no lock up problems, resulting in greater operational flexibility and no need for in-situ rebalancing

Rolls-Royce has a wealth of experience in gas turbine systems. The Marine Trent 30 is the eleventh engine type it has derived from core aero engine technology.
