| 摘要： | Green water is the term used to describe a significant mass of water coming onto the deck of a ship due to a combination of the motions of the sea and the ship. Once shipped, a mass of water can achieve significant velocities in the shallow-water environment on deck, and can exert significant pressure on deck structure and fittings. Green water incidents have a demonstrated potential for damage to deck structures, including deck plating, breakwaters, external bulkheads, deck-mounted weapons, antennas, and portholes. This study integrates a shallow-water finite volume approach with the LAMP (Large Amplitude Motion Program) ship motions analysis to find the incidence of green water and the resultant forces and pressures on deck structures. The results show expected trends in speed, sea state and ship size for the magnitude of loads and pressures. This method was applied to three ship types in a variety of loading conditions and sea conditions. |
