lifeboat Launch is a critical process in emergency situation. The most common type of lifeboat used on a cargo ship is enclosed type lifeboat, which uses offload and onload release system of lifeboat launching.
This video shows the working of these two releasing mechanisms and best practices when using onload release system.
The on load and offload release mechanisms detaches the boat from the davit, which is connected to a wire or fall by means of a hook. By releasing the hook the lifeboat can be set free to propel away from the ship.
The offload release mechanism uses hydrostatic force to part off the hooks from the fall for lifeboat launching.
On load mechanism can release the lifeboat from the wire, with the ship above the water level and with all the crew members inside the boat. The load will be still in the fall as the boat would not have touched the water. Normally the on-load release is operated when the boat is about to touch the surface of the water so that the fall is smooth without damaging the boat and harming the crew inside. A lever is provided inside the boat to operate this mechanism. As the lever is operated from inside, it is safe to free the boat without going out of the lifeboat, when there is a fire on the ship.
