    Launching of Liferaft: HRU Activates Auto

    Uploaded by

    The document describes different methods for launching a life raft from a sinking ship. It discusses: 1) How the life raft automatically launches when the ship sinks below 4 meters due to water pressure activating a knife that cuts the raft free. 2) The process for manually launching a life raft by removing the painter, securing it to the ship, removing the railing, throwing the raft overboard, and inflating it. 3) How to launch a life raft using a davit, which involves removing lashings, lowering and securing the raft canister, and letting it inflate before securing occupants and equipment and lowering it into the water.

    Launching of Liferaft
    Launching of life raft when the ship sinks and HRU activates (Auto)
     When the ship sinks up to 4 metres, the water pressure will activate a sharp knife
    in the HRU
     It will cut the securing rope around the container/canister of the raft and the raft
    will float free
     As the ship sinks further, the painter line will stretch and it will inflate the life raft
     Due to the increase in buoyant pressure, the weak link will break at around 2.2 kN
    +/- 0.4 and the raft will be on the surface

    Launching the life raft MANUALLY


     Take out the painter of the raft
     Fasten it to the ship side at a strong point
     Remove the railing and check overboard for any obstructions
     Unfasten the hook from the cradle
     Two people can lift the life raft and throw it overboard
     After its thrown, pull the painter sharp until the life raft inflates
     With the painter, pull it towards the ship side
     Lower the embarkation ladder or jump directly onto the life raft depending on the
    situation and the time at hand
     Sit order wide face to face to prevent any imbalance
     Ensure SART and EPIRB have been carried
     Take a head count
     Cut the painter using the knife given and using the paddle or the anchor, clear away
    from the ship

    If the life raft inflates and it is upside down, the raft has a righting strap which is capable
    of stabilize it. Climb onto the CO2 cylinder and pull it in the same direction as the wind
    to do so.

    Launching the life raft by the DAVIT


     Remove ship’s hand rail
     Remove lashings from the container
     Lower the davit and lock it with the lifting shackle
     Secure canister lines outboard
     Secure bowsing line
     Pull the painter out approximately 5-6 metres
     Secure the painter line
     Pull the full length of the painter
     Now lift the life raft canister up to some height
     Pull the painter sharply and let it inflate
     After it inflates, secure the liferaft
     One person should go in and make some checks
     Collect the SART and EPIRB
     Go inside and sit evenly
     Release the bowsing line and pass to the raft
     Check if the launching area is clear
     Lower the raft using the brake release
     Operate hook release 1m above the water or allow the raft to ride a crest of the wave
    to put the load on the water and it will automatically release
     Cut the painter and clear away
