A. Overside work
Overside work should only be carried out
  • based on a permit-to-work procedure
  • subject to a special procedure contained in the Company’s SMS
  • whilst the vessel is in port or at anchor
  • supervised by a competent person on board.

    The persons working overside should
  • always wear a safety harness
  • be firmly connected to fixed vessel appliances on deck
  • have access to a lifebuoy with a line ready for use.

    Communication with a responsible officer must be maintained to enable the man-overboard exercise to be put into action should the person working outboard fall into the water.

    If overside works have to be undertaken whilst the vessel is underway, such works should be carried out in accordance with the Critical Shipboard Operation Procedure in the SMS.

    Utmost care and attention is required during such operations and should only be permitted
  • in exceptional cases
  • where the safety of the vessel, the crew or the cargo is at risk.
