Watertight Door
OUCO watertight doors include sliding, hydraulic, and bulkhead options.
Our watertight bulkhead doors are typically installed between the engine room, the shaft tunnel, the boiler room, the steering gear room, as well as in any other vertical division.OUCO hydraulic watertight sliding doors are perfect for small compartments. We design the doors to be opened manually from both sides, or even from the upper deck. This is a great option to maintain safety on a ship.
We also supply our watertight doors with A0-A60 class fire protection for enhanced safety.

Our products fully comply with SOLAS guidelines and are certified by major classification societies including CCS, ABS, BV, DNV, and LR.
To ensure maximum reliability, we utilize high-grade marine steels such as DH36, EH36, and HG70 for all door constructions.
Furthermore, our doors have passed fire resistance tests per IMO FTP Code Part 3 and meet the stringent NORSOK standards for the Norwegian petroleum industry.
Custom Watertight Door Solutions
OUCO’s watertight door frames are made of aluminum, steel or stainless steel. And the panel (SA2.5) material is aluminum and stainless steel, suitable for working environments with different water pressure, stainless stee handles.
It only needs one person to operate, and the full-featured control box will meet all your usage needs. In addition, Ingress Protection (IP) Rating can be designed according to your requirements. We offer fully customizable clear opening size and outline size to seamlessly integrate with the bulkhead designs of shipyards and shipowners.
Application of Watertight Doors
Watertight doors enable a wide variety of uses, mainly used for the protection of cabins and passages. Such as vessels, port infrastructure, dry docks, offshore oil and gas platforms, offshore wind farms, nuclear power facilities, inland lakes and reservoirs. For the isolation of water, fire, harmful gases and noise.
Watertight doors facilitate the passage of personnel and cargo. We recommend sliding watertight doors for high-traffic areas. However, if lateral (side) space is insufficient for a sliding mechanism, a hinged style is the more compact choice.

Marine watertight doors refer to non-permeable metal doors installed on water-tight bulkheads and perimeter walls within a ship.
These doors are located on the compartment bulkheads and exterior walls of a ship’s superstructure, and possess the same strength as the ship’s structural design to withstand a certain level of pressure while maintaining water-tightness.
Water-tight doors allow for the passage of personnel and goods while preventing the ingress of water, fire, and toxic gases into compartments and the spread within the ship. They serve as a reliable safety barrier even during emergencies such as floods or accidents.
Marine Water-tight Doors can be classified according to their structural shape, including circular, rectangular, elliptical, and spherical pressure-resistant water-tight doors.
In general, we classify them mainly according to their closing mechanisms:
Hinged Water-tight Doors:
easy to operate and lightweight in design, and are intended to swing open and closed on hinges, similar to a typical door in a building.
They require enough space for the door to rotate open without obstructing the surrounding area, making them more suitable for smaller openings. They’re also easier to install and maintain.
Sliding Water-tight Doors:
Designed to slide horizontally along a track that is closely fitted to the wall to open and close, can move horizontally or vertically. They achieve a watertight seal through the inclined surface of the door frame and door panel.
Sliding water-tight doors are suitable for areas where the door swinging open would obstruct the limited space available, such as narrow passageways or compartments with obstructions.
The watertight and weathertight door is trendy and stands the most significant role in the marine industry.

The watertight door must undergo regular inspections and maintenance to ensure its normal and consistent operations.
In doing maintenance, it is needed to check first the overall function of the whole system including the:
- Warning alarms and related devices
- The hydraulic and electric mechanical power
- Fluid level indicators
- Lights
- Valves
- Seal
On the other hand, related inspection and maintenance must be based upon the general maintenance system.
- The watertight door, including the frames and the gasket, should be permanently clean.
- Watch out for the possible cracks, corrosion, and other structural damages to a watertight door.
- Check the wheels, bearings, and rails for possible damages and defects.
- Check the condition of the hydraulic system for possible leakings.
- Check for the connections of pumps, pipe, hydraulic cylinder, and hand pump.
- Must lubricate all mechanical parts during maintenance.
- Ensure that the watertight door must have instructions and reminders attached to it.
Insufficiency of proper maintenance and inspection of watertight doors can lead to excessive danger and risk, which probably affects the overall performance of the vessel and the life of every individual.
A Watertight door is made up of these primary materials:
- Aluminum
- Marine Steel
- Stainless Steel
- High Tensile Steel
- Glass Reinforced Plastic
