Watertight Doors On Ships

The closure between two compartments below the waterline will typically be watertight it is essential that these compartments are resistant against great water pressure as is the case during a major water leakage.

Watertight doors on ships.

The pontoon measures 30 metres and a width of 11 20 meters. These are doors below the ship water line. Ims is a specialist in sliding watertight doors for ships and drilling rigs. Doors window and portholes for pontoon antigoon for this project thormarine delivered the watertight doors a60 fire doors windows and portholes.

The mechanical gears required for manual operation of these doors must be located outside the machinery spaces. A watertight ship door or hatch withstands a so called water column water pressure from both sides. In the event of a leak the doors will prevent the vessel from sinking. All watertight doors both hinged and power operated should be operated daily during the rounds.

On the picture below you can see the example of the water tight door this is located at the accommodation below the water line. The total weight of the pontoon is about 230t. A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads it is analogous to a room within a building and may provide watertight subdivision of the ship s hull important in retaining buoyancy if the hull is damaged. Working area will mainly be in and around antwerp.

However in case of ships having twin shafts there may be two watertight doors each providing access to the two shaft tunnels on either side. Subdivision of a ship s hull into watertight compartments is called compartmentation. The crane will lift more than 200t. The doors are used to divide vessels into watertight compartments.

Drills for the operation of watertight doors shall take place every week. The door should be able to operate from both local and remote places. They can be find in engine room compartments bow thruster compartments etc.
