Technical Requirements for Cabin Moisture-proof and Waterproof Doors

I. Selection of Model, Dimensions, Quantity, and Opening Direction

Model Selection: The model of the cabin moisture-proof and waterproof door should be chosen based on the specific application scenario and design requirements, such as the LDXY-MBM model, which is suitable for various ship environments.

Dimensions: The dimensions should be customized according to the actual size of the cabin opening to ensure a tight fit between the door body and the opening.

Quantity: Determined by the number of cabin openings, with one moisture-proof and waterproof door provided for each opening.

Opening Direction: The opening direction should be determined based on the cabin's internal layout and operational convenience, typically opening outward to allow quick access in emergencies.

II. Technical Requirements

General Requirements

1.1 Cabin moisture-proof and waterproof doors must comply with relevant drawings and standards, such as the "Cabin Door Drawing Collection" TJ615(05).

1.2 The door body must have excellent watertight and airtight properties to effectively block the intrusion of water and moisture.

1.3 The door body should be made of corrosion-resistant materials, such as carbon steel or stainless steel, to adapt to the marine environment.

1.4 The door body must possess sufficient strength and rigidity to withstand various pressures and impacts during navigation.

1.5 The door body should have good thermal and sound insulation properties to enhance comfort inside the cabin.

Door Body Structure

2.1 The door leaf should be constructed from carbon steel, with internal insulation materials such as rock wool.

2.2 The door frame should be processed from cold-rolled steel plates through bending.

2.3 The door body should adopt a double-leaf design to increase structural stability.

Sealing Performance

3.1 The door body should use high-quality EPDM sealing strips with excellent aging and corrosion resistance.

3.2 When the door is closed, the sealing strips should tightly adhere to the door frame to ensure watertight and airtight performance.

Locking and Opening Mechanisms

4.1 The locks should employ high-security mechanical combination locks and anti-theft blade locks to ensure the door's safety.

4.2 The door body should be equipped with an independent manual mechanical device, allowing it to be opened and closed by hand from either side.

4.3 The door body should feature remote control operation, enabling opening and closing via buttons or remote control from the bridge or control room.

Ventilation and Air Exchange

5.1 The door body should be designed with ventilation openings or components, such as louvers or ventilation fans, to facilitate air circulation between indoor and outdoor environments.

5.2 Ventilation openings should include filtration capabilities to prevent external dust and impurities from entering.

Other Requirements

6.1 The door body surface should undergo anti-rust treatment, such as phosphating or electrostatic matte spray painting.

6.2 The door body should have good fire resistance to effectively isolate fire sources.

6.3 The door body should possess excellent sound insulation properties to reduce the impact of external noise on the cabin environment.

III. Dimensions and Opening Direction

Dimensions: Customized according to the actual size of the cabin opening to ensure a tight fit between the door body and the opening.

Opening Direction: Typically outward-opening to allow quick access in emergencies.
