  • The LSA code states “If colour coding is used, green shall indicate a properly reset hook and red shall indicate danger of improper or incorrect setting”. In this case the improper marking could potentially have led to improper resetting or operation of the on load release system.
  • Investigation by the Bahamas Maritime Authority in consultation with the ship owners, type approval body and manufacturer, has identified that the incorrect marking of the interlock position indicator markings occurred during manufacturer of the on load release system.
  • It was also noted that clear operating instructions were not posted inside the lifeboat at or near the release mechanism as required by paragraph of the LSA Code.
  • In view of above, ship owners/ managers and masters are advised :
    • To inspect the hydrostatic interlock position indicator markings on the release mechanisms installed on their lifeboats and especially lifeboats fitted with Hyundai TALON II 4.0 or 9.0 on load release hooks, to ensure that they are correctly marked as per the manufacturer’s instructions.
    • Where markings are found to be incorrect, the Classification Society issuing the ships statutory certification and the Flag Administration are advised. The manufacturers are also to be contacted in order to arrange for the defect to be rectified.
    • To ensure that clear operating instructions as required by paragraph of the LSA Code are provided within the lifeboats for the actual on load release systems installed on the lifeboat.
