A pressurised MCC container was delivered and installed in a FPSO. 

TLS temporary refuge equipped with independent gas supply system, when gas pollution occurs outside, a gas circulation system is formed inside TR, which effectively protects internal personnel from toxic gas hazards.
The compressed air bottle is used as the source of breathing gas to ensure the normal breathing of internal personnel while maintaining a slight positive pressure inside, which can effectively prevent toxic gas from entering the interior of the refuge;
The special CO2 absorption device can effectively adjust the CO2 adsorption rate and keep the CO2 content within a reasonable range;
Compared with the traditional filter protection method, the independent air supply system has the advantages of less maintenance, more stable and safer.
