Intelligent Pressurised Containers for Hazardous Offshore Areas

TLS designs and manufactures intelligent pressurised containers for demanding offshore, marine and hazardous-area applications. Our solutions are engineered to provide a safe, controlled environment for personnel and critical equipment, even in challenging Zone 1 and Zone 2 operating conditions.


​Customised Engineering for Offshore Operations

Every container is configured around the operational, equipment and certification requirements of the project. Integrated HVAC, electrical power control and pressurisation systems help maintain a safe and suitable internal environment for people and sensitive equipment.

From compact control cabins to large, fully equipped process shelters, TLS provides flexible layouts, dimensions and system configurations to support efficient offshore deployment.


Safety, Certification and Compliance

Safety is fundamental to every TLS pressurised container. Systems can incorporate fire and smoke detection, flammable-gas and H₂S detection, emergency shutdown, fire dampers, fire suppression and Ex-approved pressurisation equipment.

Containers can be designed and manufactured in accordance with applicable requirements of:

  • DNV 2.7-1 for offshore containers
  • EN 12079 for offshore-container design, construction, testing and marking
  • IEC 60079-13:2017 for pressurised rooms protecting internal equipment
  • ATEX and IECEx requirements for hazardous areas
  • SOLAS and A0/A60 passive fire-protection requirements
  • ISO 668 and ISO 1161 where onshore ISO-container standards apply
  • CSC requirements for the International Convention for Safe Containers

Third-party certification and certificates of conformity can be provided by recognised bodies such as DNV, Bureau Veritas, Lloyd’s Register or CCS, subject to the project requirements.


Integrated Systems and Rapid Deployment

TLS containers are engineered for efficient mobilisation and straightforward site integration. Depending on the application, they can include data communication networks, fire suppression, air-conditioning systems and pre-commissioned electrical and instrumentation packages.

Each unit can be supplied with material traceability documentation, load-test records, NDT certificates and the required offshore-container certification.
