Green water loading on a deck structure

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.
