Green water loading on a deck structure
WebGreen water on deck takes place when the deck becomes submerged underwater. The water on the deck may cause structural damage to the deckhouse of the ship and to the deck facility and cargo. The ship's speed is usually reduced, or its heading changed, if such an action reduces the likelihood of slamming or green water on deck. Webreferred to as green water loading. Simply stated green water is the flow of solid water on the deck of a vessel, resulting when the wave elevation exceeds the freeboard of the vessel. This creates a fast-moving flow over the deck of the vessel that can result in large loads on objects in its path. This, along

WebJan 1, 2024 · Greenwater occurs when the surrounding free surface elevation exceeds the freeboard, causing a large amount of water to flow onto the deck of a vessel. The subsequent shipped water propagates across the deck and impacts on deck-mounted structures possibly resulting in structural damage. WebThis allows the evaluation of the different options to solve the green water problem for a specific ship-type offshore structure: 1. Design the vessel and structures on the deck against the predicted green water impact load levels. 2. Optimise the bow shape (underwater shape and above water bow flare). 3.
