About offshore positive pressure container used in Zone1/Zone2
Positive pressurized containers can provide a safe environment for equipment and people in hazardous areas. The principle of a positive pressure blast-proof container is to achieve the technical requirements of blast-proofing through enclosure. A positive pressure ventilation system is the key.
It delivers fresh air from a safe area to the container through ducts that pure the air inside the container and maintain a slightly higher air pressure inside the container than outside. In this condition, no harmful and flammable gas can enter the enclosure.If the blast control system detects the presence of hazardous gases in the enclosure or fails to maintain positive pressure, the alarm system will sound an alarm and issue a warning. If the control conditions inside the container are still not required within the specified time, the non-explosive device will automatically cut off. Thus, the common equipment in the container fulfils the purpose of blast protection.

About CPFG（combined pressurization fire&gas system) of positive pressure container
CPFG is a complete suite of intelligent booster control systems, typically used in positive pressure containers, with gas detectors, smoke detectors, heat detectors, fire alarms, pressure switches, flow switches, booster fans, emergency stop & alarm mute switches, and other explosion protection equipment.
The CPFG is also connected to a power distribution board, which will be connected by non-explosive devices inside the container, such as sockets, fume hoods, computers, water heaters, etc.
When the power is turned on, the CPFG turns on the booster fan to purge the inside of the container to positive pressure. This prevents dangerous gases entering from outside. When the environment inside is safe, the DB (distribution board) will start up and the internal non-explosive electrical equipment can be used normally. The DB cannot be started if the environment inside the container is not secure.
During operation, if dangerous gases are detected in the container or the positive pressure cannot be maintained, the alarm system will sound an alarm and issue a warning. If the control conditions in the container are not met within the specified time, the non-explosive device is automatically turned off. Therefore, the general equipment in the container is suitable for blast protection purposes.

​The production process and requirements for TLS offshore container are as below:
1. Produce the container frame and weld the container.
All primary structural welds are required to be welded by a class-certified welder, and full penetration welding is required. For containers that have passed the third-party inspection, they are sprayed according to the paint process, and the paint package is suitable for the marine environment

2. Install the floor.
First, calcium silicate plates were laid on the lower deck, then fixed steel mesh was installed on the surface, then the upper deck dressings were laid on the steel mesh, and finally the deck dressings were laid on the floor. After construction is complete, the flatness of the floor is measured and accepted by professional quality inspectors.

3. Lay down insulation material.
Fix the nails in advance at the locations where the rock wool insulation needs to be laid in the container. When attaching the nails, reserve space to make sure that the nails are firmly attached according to the standard.  Laying of rock wool ensures that the length of the overlapping surface is sufficient, and the joints are covered with fireproof tape.

4. Install water pipes, air pipes, and cable trays.
Pre-lay insulation. Reserve the supporting boom needed to install the pipe on the top plate of the container to ensure that the pipe is straight and firmly secured.

5. Install interior trim wall panels.
Install the fixing slot of the fixing plate first, and then install the inner panel in the fixing slot. Before installation, ensure that the surface of the wall panel and the ceiling is smooth and flat, and ensure that the splicing gap is neat and straight.

6. Install the furniture and appliances. The furniture in the container must be installed and secured according to the requirements and locations in the preliminary design drawings. The power connection of the relevant equipment shall be constructed in accordance with the regulations and must be inspected by qualified quality inspectors during this period.
​
7. Testing & Acceptance
TLS accepts client's on-site inspection, video inspection, graphic inspection, and other methods for acceptance. We will only ship the containers after they pass the acceptance.

Offshore shipping containers are widely used for the transportation and hoisting of goods or equipment between offshore facilities and ships in harsh environments with high temperature, high humidity, and high salt spray. Therefore, there are extremely high requirements for the anti-corrosion of the surface of the offshore container.
The coating process steps of TLS are as follows:
1. Preprocessing
Remove the oxide scale, rust, grease, dirt, and other attachments on the surface of the exposed steel structure to ensure the anti-corrosion performance of the coating;  zinc-rich primers are applied automatically on the assembly line after the steel is shot-blasted. It temporarily protects the surface of freshly shot steel, preventing it from rusting in the gaps made during the container's manufacture.
2. Shot-blasted the whole container
Before painting, the surface of the weld and the heat sensitive area of the weld should be shot-blasted. The surface of the steel structure should be free of burrs, bumps, dust, dirt, no painting, sharp edges, and all rough-cut edges should be ground to a radius of at least 2mm;
3. Pre-coating
Pre-coating is applied to areas that are not easy to coat, including, but not limited to, the edges of steel plates, welds, corners, bolt holes, beam edges, and other areas that are difficult to paint.
4. Spray
Each coat should be applied evenly over the entire surface, and defects such as missing paint, sags, and drips must be avoided. And each coating should contain no pinholes, blisters, and leaks. 
5. Drying: Speed up the curing process. 
TLS uses environmentally friendly water-soluble paints, and the coating operators have relevant technical certifications.  TLS containers are not prone to corrosion, paint failure, fading and discoloration which can make the container work better for its use value.
