Engine Room Details
Standing on the catwalk between the ship's two LM2500 gas turbine engine
These frigates have two LM2500 engines for high speed, and a single
diesel for low speed cruising. The LM2500 is by far the most common
marine gas turbine engine, and is employed in many navies around the world.
A view into the engine module, showing part of the LM2500 turbine itself.
The enormous complexity of these engines is readily apparent - yet they
are robust, reliable machines with a fine service record.
This view shows one LM2500 engine module at right, and the reduction gear
to the left.
The reduction gear matches the high-speed turbines to the propellers,
which are most efficient at low speeds.
A view from the other side of the reduction gear, showing the shaft
coupling connecting the propeller shaft.
Another view of the engine room, with an LM2500 module behind a
collection of piping and gauges.
This view is an excellent demonstration of the congestion that is common
in machinery spaces.
Sailors at the central control station from which all the engines can be
controlled and monitored. The ability to control machinery centrally
is a great advantage in modern propulsion systems.
