GE Marine will continue to maintain GE LM2500 marine gas turbines of Canadian Navy Halifax-class frigates


According to information released on September 1, 2021, GE (General Electrics) Marine announced it has renewed a long-term, customized service agreement (CSA) with the Royal Canadian Navy (RCN). The CSA covers an operating fleet of 24 GE LM2500 aero-derivative marine gas turbines plus spare engines used to power Halifax class frigates.

General Electrics (GE) has been providing the RCN with 20 years of customized service for their LM2500 engines, yielding significant performance and operational advantages in terms of improved reliability and the high availability of the gas turbines to power their surface combatants, said Kris Shepherd, Vice President, General Manager, GE Marine.

The CSA (Customized Service Agreement) provides the Canadian Navy with high availability of the RCN’s LM2500 fleet over the initial five years of contract support, as well as helping to promote supplier and skills development in Canada. The five-year contract comes with renewal and sustainment options until the eventual decommissioning of the Halifax class frigates,” added Shepherd.

The General Electrics LM2500 marine gas turbine is a simple-cycle, two-shaft, high-performance engine. Derived from GE's CF6-6 aircraft engines, the LM2500 consists of a gas generator, a power turbine, attached fuel and lube oil pumps, fuel control and speed governing system, associated inlet and exhaust sections, lube and scavenge systems as well as controls and devices for starting and monitoring engine operation.

The LM2500 is GE's most widely-applied gas turbine, used by 33 navies worldwide. Possible applications for the LM2500 include patrol boats, corvettes, frigates, destroyers, cruisers, cargo/auxiliary ships, and aircraft carriers. The LM2500 is also available as a military generator set.

The Halifax-class also referred to as the City-class, is a class of multi-role patrol frigates that are in service with the Royal Canadian Navy since 1992. The ship is powered by a combined diesel or gas (CODOG) type propulsion system including two General Electric LM2500 gas turbines, generating 47,500 shp (35,400 kW), one SEMT Pielstick Diesel engine, generating 8,800 shp (6,600 kW), one Royal de Schelde cross-connect gearbox, two Escher Wyss controllable pitch propellers and four 850kW AEG Telefunken generators. The ship can reach a top speed of 30 knots (56 km/h) with a maximum cruising range of 9,500 nautical miles (17,600 km).
