A watertight hatch with the door dogs clearly visible Three types of doors are commonly used between compartments. A closed watertight door is structurally capable of withstanding the same pressures as the watertight bulkheads they penetrate, although such doors require frequent maintenance to maintain effective seals, and must, of course, be ...
locking off the damaged area from other ship's compartments; blocking the damaged area by wedging a box around a tear in the ship's hull, putting a band of thin sheet steel around a tear in a pipe, bound on by clamps. More complicated measures may be needed if a repair must take the pressure of the ship moving through the water. For example:

Watertight doors minimize flooding during the grounding or collision of a ship or when a ship undergoes structural damage and thus, minimize the risk of sinking as in the event of severe structural damage, the ship might be flooded with water. Watertight doors are crucial for all marine vessels including commercial, yachts, cruiser, coastal ...
On 14 May 2019 it was reported the cost of repairing Helge Ingstad would exceed US$1.4 billion, according to the Norwegian Armed Forces, implying that it would be nearly three times cheaper to build a new ship. However, restarting production for just one ship could result in a disproportionally high per-ship cost.
One of the factors contributing to the ship's sinking was the open manhole used to access the bow structure sonar dome containing the boat's sonar sphere. The manhole has a bolted cover which had been removed for maintenance purposes. The opening was protected by a cofferdam approximately 3 feet (0.91 m) high. The cofferdam was intended to ...
The sunken vessel, lying on the seabed at a depth of some 50 meters (164 feet), is thought to have watertight safes containing two super-encrypted hard drives that hold highly classified ...
