Marine auxiliary

Auxiliary generating sets and harbour-duty engines aboard vessels.

The problem

A vessel’s auxiliary sets run at berth and under way, in a confined engine room with its own exhaust routing and its own safety rules. The operator faces port air-quality regimes and has almost no room to alter the engine.

Engine envelope

Fuels
Marine diesel auxiliary sets.
Power band
Auxiliary sets by survey; not main propulsion.
Duty cycle
Harbour duty, at-berth, and auxiliary running under way.
Not in envelope
Not main propulsion engines, not steam plant, and nothing that would compromise the vessel’s class or its exhaust safety case.

What a survey includes

  • A survey aboard, subject to the vessel’s own safety and access rules.
  • The auxiliary set make, model, rating, and exhaust routing.
  • The class and survey constraints that bound any modification.
  • How and when a set can be taken offline in service.

How we measure

We do not quote a figure before we have seen your engine. We measure your engine before and after fitting, under a protocol agreed with you, on your fuel and your load — and we give you those measurements.
