Merchant Navy CareersWhat is an electro-technical officer (ETO) and what do they do?
An electro-technical officer is a specialist engine-department officer responsible for a ship's electrical, electronic and control systems, a rank formalised under STCW.
Marine MachineryWhy won't two generators share load equally when running in parallel?
When paralleled generators fail to share load evenly, the fault lies in the governor and speed settings for active power, or the excitation for reactive power.
Merchant Navy CareersHow do you become an electro-technical officer (ETO)?
Becoming an ETO means entering the engine department through an electrical or electronic background, completing approved training and sea service, and gaining the STCW electro-technical officer certificate.
Marine MachineryWhat is a governor on a marine engine and what does it do?
A governor automatically controls an engine's speed by adjusting the fuel supply to match the load, keeping the engine at the required revolutions or a generator at constant frequency.
Marine MachineryWhat is a shaft generator and why is it used?
A shaft generator produces electrical power by being driven from the main engine or propeller shaft, so the ship can meet its electrical needs at sea without running separate auxiliary generators.
