Quick Acting Weather-tight Hatch for Marine Deck Installation

Product Overview

Engineered for outdoor and open-air working conditions, this quick acting weathertight hatch delivers reliable weathertight sealing performance, single-person quick acting operation, and exceptional durability, providing safe, convenient access for personnel passage and equipment maintenance on marine vessel open decks, offshore platforms, port equipment, and industrial outdoor facilities. Manufactured with high-grade steel main structure and corrosion-resistant stainless steel core components, the hatch resists harsh elements including heavy rain, sea spray, salt fog, sand, and strong wind, ensuring long-term stable performance in demanding outdoor environments.

Technical Specifications

Marine rectangular quick-opening pressure-resistant weatherproof and watertight hatch door                   

This product is a dedicated steel rectangular enclosed hatch cover for ships, featuring a thick plate integral welded structure. It is equipped with a spring-actuated quick-lock mechanism and a central handwheel locking sealing system, strictly manufactured in compliance with maritime classification society standards. With excellent deep-water pressure resistance,(weatherproof and watertight) capabilities, and corrosion resistance to marine salt spray, it serves as a core fitting device for secure compartment isolation in ship cabins.

Core Product Advantages

Manual fast-opening and fast-closing structure with spring hinge interlocking lock, enabling synchronized full chamber pressure sealing via a single handwheel, ensuring rapid response for emergency scenarios on board

High-tensile strength specialized marine waterproof sealing strip, ensuring zero leakage in high-pressure environments and rapidly blocking water flow spread in case of hull breaches to safeguard vessel navigation safety

Thickened marine-grade steel, with an epoxy anti-corrosion coating process, designed for long-term adaptation to harsh offshore conditions of high salt spray and humidity, ensuring durability and resistance to deformation and rust

Deck-mounted horizontal dedicated installation structure, suitable for universal installation in vertical/horizontal maintenance openings on most ship decks and cabins

Applicable scenarios

Various types of cargo ships, bulk carriers, fishing vessels, and special-purpose engineering vessels, including engine rooms, steering gear rooms, boiler rooms, double bottom tanks, ballast water tanks, and cargo oil tank decks, as well as access points for maintenance, are also suitable for sealing and protection of enclosed hatches on offshore oil platforms, marine wind power platforms, and other marine engineering structures.

Customized service
