The aims of this Web Site are:

  • To provide and share information on the construction, running and maintenance of both slow speed 2 stroke marine diesel engines and medium speed 4 stroke marine diesel engines as found on the majority of ocean going merchant vessels.

  • To aid cadet engineer officers in their understanding of these large powerful engines.

  • To help students studying towards MCA certificates of competency by giving hints on how to answer examination questions.

  • To provide links to manufacturers, regulatory bodies, and other sites of interest.
