Today's large ocean-going vessels are powered by gas turbine engines. Many of these engines are variants of aerospace engine types. The marine variants must undergo similar testing to that of their airborne cousins.

Large vessels may use gas turbines as electrical power generators to drive electrical motors connected to the propellor driveshaft.

A gas turbine engine physically connected to a propellor shaft through a geared transmission system has its own particular vibrational stresses. Small high-speed vessels may have their propellors clear of the water on occasion. This causes considerable strain to the engine, which is most efficient when operating at constant speed. Our dynamic analysis techniques help engineers to determine the likely behaviour of engines under different dynamic load conditions.

Rotating machinery analysis is of use in the monitoring of vibrations and dynamic stresses in offshore industries such as oil rigs and exploration platforms. Gas turbines are used extensively for power generation and pumping.
