For marine engine repair, the most important thing is to make available several sets of spare parts on board the ship. If there is a shortage of any of these parts, then they need to be ordered by the respective engineer, who is looking after the particular machinery.

Maintenance is necessary to keep a ship running well and looking good. It can be done as part of an inspection or as scheduled maintenance. Inspections happen regularly but scheduled maintenance should happen according to the ship’s book, which details how often certain things need to be inspected and/or maintained.
