Marine Scupper
Marine Scupper is a drainage device designed for removing rainwater, seawater, and other liquids from ship decks and marine structures.
Installed on ship decks, superstructures, and offshore platforms, Marine Scupper provides an efficient drainage solution to prevent water accumulation and maintain safe operating conditions.
The scupper system allows water collected on the deck surface to flow safely through piping or overboard discharge systems.
Marine Scupper is widely used in:
Main deck drainage systems
Weather deck drainage systems
Passenger ship decks
Cargo ship decks
Offshore platforms
Marine engineering structures
Overview
Working Principle of Marine Scupper
Marine Scupper works as a drainage connection between the ship deck surface and the drainage pipeline system.
The operating process:
Rainwater or seawater collects on the deck surface.
Water flows into the scupper inlet.
The scupper guides water into the drainage pipe.
The drainage system discharges water safely overboard or into collection tanks.
The structure prevents water accumulation on deck areas.
