Green water loading on a deck structure
WebDec 1, 1995 · For weather-vaning turret moored FPSO`s in survival conditions the bow is always exposed to the wave action. When the waves come above the freeboard, this can result in considerable amounts of green water on the deck. This can cause damage to the sensitive equipment at the bow, like the fluid swivel, piping, turret structure and … WebThe strongly non-linear relative wave motions at the bow can come above the freeboard of the vessel and result in green water flow onto the deck. To design an FPSO against green water, it is important to know the amount of green water and the resulting impact loading on structures at the deck.
