More gas turbines for Korean FFX-II frigates [CANSEC17D1]

31 May 2017

Rolls-Royce (Booth 1621) has been contracted by Hyundai Heavy Industries (HHI) to supply a further three MT30 marine gas turbines to power the next three ships in the Republic of Korea Navy’s (RoKN’s) FFX Batch 2 Daegu class frigate programme.

In this application, a single MT30 is being fitted as part of a combined diesel electric or gas turbine (CODLOG) machinery arrangement.

The company has previously delivered a single MT30 for the FFX Batch 2 first of class ROKS Daegu, which is currently completing at the Okpo yard of Daewoo Shipbuilding and Marine Engineering (DSME). Ship two will also be built by DSME, while ships three and four are under contract to HHI’s Special and Naval Shipbuilding Division.

The MT30 gas turbines for ships two and three are due to be delivered in the second half of 2018, and for ship four at the start of 2019. The engine is shipped to South Korea for packaging by HHI’s Engine & Machinery Division. This process sees the gas turbine unit integrated into a steel enclosure, which also houses air inlets, exhausts and ancillary equipment, prior to installation in the ship.

For the FFX Batch 2 programme, lead ship Daegu was launched from DSME’s Okpo yard in June 2016. The ship is scheduled for delivery to the RoKN in late 2017 and expected to be commissioned in late 2018.

According to Don Roussinos, Rolls-Royce, president – naval, the MT30 gas turbine has been successfully installed in Daegu and “is currently successfully supporting the commissioning of the [CODLOG] propulsion system”. He added: “We understand that MT30 has powered the ship to meet its full speed requirement.”

Derived from Rolls-Royce Trent aero engine technology, the MT30 is initially built as separate modules on the same build line as the Trent in Derby. It is then assembled and tested at the company’s Bristol facility.
