Common Marine Inspection Document

The Common Marine Inspection Document (CMID) (IMCA M 149) is a free to use marine inspection format provided by the International Marine Contractors Association for the inspection and audit of marine vessels involved in the offshore industry. The inspection's purpose is to establish that a particular vessel is safe to work aboard, will not place anybody working on or around the vessel in danger and will not cause any harm to the environment. The inspection also ensures that all mandatory certification for the vessel and its operations are up to date.

The inspection contains 17 sections including:
 * Vessel Particulars
