An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...
[1] [2] WR-21 development draws heavily on the technology of the successful Rolls-Royce RB211 and Trent families of gas turbines.

For an example the new CODAG-propelled Fridtjof Nansen-class frigates of the Royal Norwegian Navy, the gear ratio for the diesel engine is changed from about 1:7.7 (engine:propeller) for diesel-only to 1:5.3 when in diesel-and-turbine mode. Some ships even have three different gear ratios for the diesel engines — one each for single-diesel ...
Principle of a CODLAG propulsion system. Combined diesel–electric and gas (CODLAG) is a modification of the combined diesel and gas propulsion system for ships.A variant, called the combined diesel–electric or gas (CODLOG) system, contains the same basic elements but will not allow simultaneous use of the alternative drive sources.
