Rolls-Royce's MT30 gas turbines to power ROK Navy's Daegu-class frigates


Rolls-Royce has secured a new contract to deliver MT30 marine gas turbines for the next three vessels in the Republic of Korea (ROK) Navy's Daegu-class frigate programme.

The Daegu-class frigates are known as FFX Batch 2 and will be capable of carrying out a wide range of missions such as anti-air warfare, anti-submarine warfare, patrol, surveillance, search and rescue, transport, and protection of exclusive economic zone (EEZ).

A total of eight FFX Batch 2 vessels are slated to be developed for the ROK Navy, and the series' first unit is currently being constructed by Daewoo Shipbuilding and Marine Engineering (DSME).

The first Daegu-class frigate was launched at the company’s Okpo shipyard in June last year.

The second frigate of the same class was also built by DSME, whle the third and fourth vessels were developed by Hyundai Heavy Industries (HHI) Special and Naval Shipbuilding Division (SNSD).

Rolls-Royce Naval president Don Roussinos said: “Our continued supply to this programme validates our on-going relationship with DSME and HHI.

“The Daegu class is an exciting programme. It is the world’s first frigate to use a single MT30 in the compact package and our first application for MT30 outside the UK and US markets.

“The MT30 gas turbine has been successfully installed in ship one and is currently successfully supporting the commissioning of ROK Daegu’s propulsion system. We understand that MT30 has powered the ship to meet its full speed requirement.”

The MT30 gas turbines for the second and third Daegu-class vessels are slated to be delivered in the second half of next year, with the fourth ship's turbine expected in early 2019.

MT30 builds on more than 45 million hours of operating experience and ultra-high reliability, and is based on from the company’s Trent aero engine technology.

The in-service marine gas turbine will deliver a high-power output in a compact space with significant power density.

The MT30 engine is set to be assembled and tested at Rolls-Royce’s Bristol facility and will be integrated by HHI Engine & Machinery Division into a steel enclosure prior to installation in the vessel.
