Q45- Green seas definition

Answer

A- It refers to seawater that travels over the weather Deck of a ship without any w waves breaking

- This condition occurs when the se ea water comes onto the ship’s Deck, creating so o called “GreenSeaLoads”.

-

Green Sea Load represents the

pressures & forces exerted by the water that wa shes over the bow or the

Deck of the ship.

This load depends on wave e height, ship speed & ship type & estimation involv ves complex modeling,

where the behavior of wav ves on the ship Deck can be described using mod dels like flooded waves.

This concept is linked to saf fty regulations & class requirements to ensure ships a re structurally capable of

withstanding these loads in s severe sea conditions.

These loads can affect ship p motions & the structural integrity of the vessel.

This is imp. for ship design & & safety assessment especially when Deck wetness s occurs frequently in rough

seas.
