WHAT BASIC TESTS WILL THE FACTORY DO BEFORE THE CONTAINER DELIVERY?

1/21/2022

1 WELDING INSPECTION
Welding inspection of containers, including inspection and NDT.
The whole inspection process runs through the manufacturing process of containers, not limited to the final product, and adjusts production at any time to ensure welding quality.

2 LIFTING TEST
In addition to the test required by international container safety convention, our company will also carry out a two-point and four-point lifting test.
The two-point lifting test mainly tests the anti-deformation ability of containers at sea under extreme conditions, and the four-point lifting test mainly tests the carrying capacity of containers at sea. Both tests do not allow permanent deformation of containers at sea during accelerated crane lifting.

3 DROP TEST
The main purpose of the drop test is to examine the impact of the lifting and placing of containers at sea to ensure that the cabinet can withstand the damage caused by the impact.

4. WATER TIGHTNESS TEST
The container body is sprayed with high-pressure water from all directions, and will be checked in all directions after spraying to ensure that there is no water in it.

HOW TO CHOOSE POSITIVE PRESSURE and NEGATIVE PRESSURE?

1/13/2022

Positive pressure and negative pressure are relative to the pressure in the surrounding space.

Positive pressure: the air supply volume is greater than the exhaust volume. The indoor air is under positive pressure. Combined with the air conditioning unit, the cleanliness of the air sent into the container can be guaranteed.
Positive pressure is preferentially applied to containers where the external environment is harsh (such as ZONE 0, ZONE 1, and ZONE 2) and the internal environment is secure.
Please download the A60 offshore pressurised container product brochure for reference.

Negative pressure: the air supply volume is less than the exhaust air volume, and the room is under negative pressure. The surrounding air flows into the space and is discharged through the exhaust outlet for unified treatment.
Negative pressure is preferred in containers where the external environment is safe but the interior will produce toxic and harmful gases.

How doES THE CPFG of OUR offshore positive pressure container work?

1/12/2022

CPFG means "Combinated Pressurization, Fire and Gas" shutdown system. According to IEC60079-13(2019) and "Safety Rules for Offshore Fixed Platforms", the functional container will have a positive pressure air purge mode. When CPFG is turned on, CPFG will first control the blower fan to make the main cabin carry out air change at least 12 times per hour, and make the main cabin reach a positive pressure environment of >=50PA. When the main warehouse to achieve positive pressure 50PA environment, indoor safety zone, cabin DB(distribution board) will get electricity, so that air conditioning, sockets, lights and other electrical appliances get electricity, all sockets, air conditioning machine (non-explosion-proof), part of the lights.

Why airlock room is needed for pressurized container?

1/5/2022

What is airlock room?

The air lock area is located at the cabin door, separating the cabin door from the work area, and is the transition area into the work area.

How to ensure the pressure balance of the pressurized container?

The inner wall part forming the air lock area is provided with an inner door for entering and leaving the work area. The cabin be provided with a pressure monitoring device to ensure the pressure balance in the cabin.

What is airlock room for?

The installation of the two doors in the airlock area ensures that the protective pressure in the main room does not drop to zero when entering the airlock area after opening the airlock door.

Escape doors can be installed on the walls away from the airlock area in case of crisis, further improving the safety of the cabin. The positive pressure explosion-proof offshore function cabin makes maximum reasonable use of the limited space and provides a more comfortable and safe living and working environment for the staff on the complicated and changeable offshore platform.
