A more thorough explanation:

Definition: Marine service, also known as maritime service, refers to work performed in connection with a ship or commerce on navigable waters. This includes services to preserve a ship's crew, cargo, or equipment. It falls under maritime law.

Examples: Examples of marine service include:

• Repairing a ship's engine
• Providing medical assistance to a crew member
• Transporting cargo from one port to another
• Assisting in the salvage of a sunken ship

These examples illustrate how marine service involves a wide range of activities that are essential to the safe and efficient operation of ships and the transportation of goods. Without marine service, ships would not be able to function properly and commerce on navigable waters would be severely impacted.
