Green water loading on a deck structure
WebDec 14, 2024 · Abstract. This paper gives a detailed description of the main hydrodynamic characteristics of different types of green water events occurring on a fixed structure in a series of experiments. High-speed video, at 250 fps, was used to capture the flow details from regular waves produced inside a wave flume. The green water events were … 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.
