Generating Set – Type Approval & Classification

Type Approval

It is unusual for a complete marine generating set to be ‘type’ approved as this would only be valid for an absolute standard or specific specification and would not apply when the generating set is altered and built to suit specific customer/vessel requirements. Type approval however, can be applied to the main components such as the diesel engine and the main electrical alternator. As a consequence for type approved marine generating sets, Beta Marine can supply the following certifications:

  1. Engine design or type approval certificate.
  2. Alternator type approval certificate.
  3. A Beta Marine combined works test certificate for the complete generating set.

Generally, manufacturers type or design approval certificate copies are supplied free of charge.


If a vessel is “classified” and the class notation calls for the marine generating set to be “in class” then unless there is an exception allowed for by the relevant class rules, the complete generating set will be subject to the relevant classification society rules.

Once built to the relevant classification society rules, the complete engine, alternator and all its ancillaries will need to be fully surveyed and witness tested at the factory by the classification society surveyor/s. Upon completion, full class certificates will be issued specific to each generating set.

The requirements vary between classification societies and the relevant society surveyor should be consulted prior to ordering to ensure the generating set customer/vessel specification is acceptable for the class.

The benefit of this process is the generating set has been proven and is compliant before being shipped and received on board.

Classification Society compliance and certification is a chargeable extra and will allowed for in your bespoke generating set quotation.

Note: Please note that not all engines are available with ‘type’ approval and some engine manufacturers do not offer or allow their engines to be surveyed and witness tested by class society surveyors in their factory.

Beta Marine specialise in bespoke customer specification, for support on optional or bespoke control modules, please contact one of our specialist generating set team on the Beta Marine Help Desk.
