Calculating Sea Service

Sea Service must be calculated in months and days using the following rules:

  • One month is calculated from the date you joined the vessel to the preceding day of the following month irrespective of the number of days served.

    Example: If you join a vessel on the 15th of one month and serve on board until the 14th day of the following month, that is calculated as one month sea service.

  • Odd days should be added together and reckoned at 30 days per month.

    Example: From 03rd Jan to 05th March calculates as two months and three days sea service.

  • No day may be counted twice.

    Example: If you leave one vessel and join another vessel on the same day, that day can only be counted once.
