What type of engine starter motor is commonly found on the marine gas turbine shown in the illustration? Illustration GT-0006

Correct Answer: Option A — Hydraulic motor

Many large marine gas turbines utilize hydraulic starters due to their high power-to-weight ratio and ability to provide the significant torque required for initial rotation. These systems are integrated into the engine's auxiliary systems, drawing power from the ship's hydraulic plant to spin the compressor during the start sequence.
