In navies and the maritime industry, damage control is the emergency control of situations that may cause the sinking of a watercraft. Examples are:
Ship grounding is a type of marine accident that involves the impact of a ship on the seabed, resulting in damage of the submerged part of her hull and in particularly the bottom structure, potentially leading to water ingress and compromise of the ship's structural integrity and stability. Grounding induces extreme loads onto marine structures ...
To keep a certificate all class requirements are compulsory. The continuous survey hull (CSH) and Continuous survey machinery (CSM) are survey methods for the mooring, anchoring and the propulsion system. The special survey cycle (SS) is an alternative for the CSH [clarification needed] and Engine survey (ES) for the CSM. The annual survey (AS ...
Before this, a hull breach in any part of a vessel could flood its entire length. Transverse bulkheads, while expensive, increase the likelihood of ship survival in the event of hull damage, by limiting flooding to the breached compartments they separate from undamaged ones.

The "local" Earth/Ground electrode provides "system grounding" [13] at each building where it is installed. The "Grounded" current carrying conductor is the system "neutral". Australian and New Zealand standards use a modified protective multiple earthing (PME [ 14 ] ) system called multiple earthed neutral (MEN).
