Engine Room Maintenance and Cleaning
A well-kept engine room means more than just keeping tidy — it is vital to the safety of the crew and the vessel. According to class society DNV GL, a shipowner operating 20 vessels can expect one major engine room fire every 10 years. Because improperly maintained engine rooms can lead to navigational failure or to engine room fires, Port State Control Inspectors typically will target engine room spaces during their onboard inspections, with particular emphasis placed on cleanliness.
