Rolls-Royce Completes Factory Acceptance Test Of MT30 Gas Turbine For Royal Navy’s Type 26 Combat Sh

[Zarvan]

Rolls-Royce on Monday marked the completion of a successful factory acceptance test for the first MT30 Gas Turbine for Royal Navy’s new Type 26 Global Combat Ship programme.

Rolls-Royce has signed a contract to supply MT30 gas turbines for the first three Royal Navy Type 26 Global Combat Ships. The company has also signed Design Development Agreements (DDAs) with BAE Systems for steering gear, stabilisers, and mission bay handling equipment. There is also a DDA in place for diesel generator sets to power the ship’s electric drive system.

Philip Dunne MP, Minister for Defence Procurement, said: “I am very pleased to welcome the delivery of the first Type 26 Global Combat Ship MT30 Gas Turbine engine, which will be a key long lead item for the programme. The Type 26 will be a multi-mission warship with capability to meet the future demands of the maritime environment, including complex combat operations, counter piracy, humanitarian and disaster relief work.”

Geoff Searle, BAE Systems, Programme Director Type 26 Global Combat Ship, said: “Today is a significant milestone on our journey to deliver Type 26 to the Royal Navy and it really shows the momentum that there is behind this programme.

“Type 26 will be the backbone of the UK’s surface fleet and a strong industrial base is essential to sustaining this naval capability. Our partners and suppliers play a key role in working with us to deliver this programme, which is supporting a great many skilled UK jobs in BAE Systems and across the whole supply chain.”

Don Roussinos, Rolls-Royce, President – Naval, said: “Successful completion of the factory acceptance test is a significant achievement for everyone involved in the Type 26 Programme.

The Type 26 GCS has a CODLOG configuration which is slightly different from the Type 23 (CODLAG).
These ships are pretty quite while running on electric motors.

Just for understanding:

Combined diesel-electric and gas (CODLAG) is a modification of the combined diesel and gas propulsion system for ships.
A variant, called the combined diesel-electric or gas (CODLOG) system, contains the same basic elements but will not allow simultaneous use of the alternative drive sources.

A CODLAG system employs electric motors which are connected to the propeller shafts (usually 2). The motors are powered by diesel generators. For higher speeds, a gas turbine powers the shafts via a cross-connecting gearbox; for cruise speed, the drive train of the turbine is disengaged with clutches.

This arrangement combines the diesel engines used for propulsion and for electric power generation, greatly reducing service cost, since it reduces the number of different diesel engines and electric motors, requiring considerably less maintenance. Also, electric motors work efficiently over a wide range of revolutions and can be connected directly to the propeller shaft so that simpler gearboxes can be used to combine the mechanical output of turbine and diesel-electric systems.

Another advantage of the diesel-electric transmission is that without the need of a mechanical connection, the diesel generators can be decoupled acoustically from the hull of the ship, making it less noisy. This has been used extensively by military submarines but surface naval vessels like anti-submarine vessels will benefit as well.
