Welded Marine Deck Scupper with Integrated Trap

A welded deck scupper fitted with an integrated water and foul-air trap, designed for permanent installation into ship decks, offshore platforms, and marine accommodation areas. Built to handle the demands of continuous drainage in marine environments, the assembly prevents odours, gases, and backflow from entering occupied spaces through the drainage system.

The scupper body is designed for direct welding into steel decks and structural floors, creating a secure, watertight connection that requires no mechanical fasteners. The integrated trap retains a water seal at all times, blocking foul air from rising back through the drain line — a critical requirement in galleys, bathrooms, and accommodation spaces.

Supplied to the requirements of leading classification societies, these scuppers are suitable for use in class-approved marine drainage systems and offshore process installations.

Applications:

• Weather deck and internal deck drainage on commercial vessels
• Accommodation and sanitary drainage on cruise ships and ferries
• Galley and bathroom drainage in marine and offshore installations
• Offshore oil and gas platform drainage systems
• Utility and process deck drainage on offshore structures
• Naval vessel deck and service space drainage
• Industrial marine drainage systems requiring odour control
