Product Detail

Marine Life Raft – D Type Davit Launched Life Raft

The davit-launched marine life raft is designed to be hung at the ship’s side using launching equipment. It can be inflated and brought onboard from the ship’s deck. In case of davit failure, it can also automatically inflate like a throw-over type. This inflatable life raft is commonly used on passenger ships and cargo vessels, offering a capacity of 15-25 persons. Equipped with a private free-fall device, it is lowered into the water using steel ropes from an installation height of 18m-35m above the water surface.

The Basic Information Of D Type Davit Launched Life Raft

  • Lifespan: Typically lasts for 10 to 15 years.
  • Capacity: Available in 16, 20, and 25-person capacities.
  • Canopy: Equipped with a canopy to protect occupants from exposure to the elements.
  • Watertight Floor: The floor is watertight and insulated to provide protection against cold water.
  • International Voyage: Suitable for installation on ships undertaking international voyages.
  • Max. Storage Height: The installation height ranges from 18m to 35m above the water surface.
  • A Pack and B Pack: Two packs available for ships engaged in short international voyages.

The Inflation Method Of D Type Marine Life Raft

  • Launching from Ship’s Side:
    a. Initial Position: This marine life raft is hung at the ship’s side using the dedicated launching equipment, typically a single-arm davit.
    b. Inflate and Boarding: When the evacuation is initiated, the liferaft is inflated with the required air pressure. Once inflated, evacuees can board the inflatable life raft directly from the vessel deck. This eliminates the need for individuals to enter the water before accessing the liferaft.
  • Automatic Inflation in Case of Davit Failure:
    a. Redundant Safety Feature: The D type marine life raft is designed with a redundant safety mechanism in case the davit launching system fails or malfunctions.
    b. Same Inflation Method: If the davit launching system fails, the marine life raft can be automatically inflated using the same inflation method as the throw-overboard type liferafts. This typically involves an automatic inflation system triggered by hydrostatic pressure or other sensors.
    c. Independent Operation: The automatic inflation system ensures that the liferaft can be deployed and inflated even without the use of the davit launch equipment. This provides an additional layer of safety and ensures that the inflatable life raft is available for use in emergency situations.
