Marine Deck Floor Drain
Marine Deck Floor Drain is a drainage fitting designed for collecting and removing water from ship deck floors, accommodation areas, machinery spaces, and offshore structures.
Installed at low points of deck surfaces, the floor drain collects rainwater, seawater, cleaning water, and other liquids through a drain cover or strainer, then transfers them into the vessel drainage system.
Marine Deck Floor Drain is commonly used in:
Accommodation areas
Engine rooms
Machinery spaces
Galley areas
Passenger ship decks
Working decks
Offshore platforms
Compared with general deck drains, Marine Deck Floor Drain focuses on surface water collection and daily drainage management.
Overview
Working Principle of Marine Deck Floor Drain
Marine Deck Floor Drain works by collecting water from the deck surface and transferring it into the ship drainage pipeline system.
Operating Process:
Water flows toward the lowest point of the deck.
Liquid enters through the drain cover or strainer.
The drain body filters large particles and debris.
Water flows through the outlet connection into drainage pipes.
The drainage system discharges water safely overboard or into a collection tank.
