In high-risk environments such as offshore platforms, drilling rigs, nearshore wind farms, and remote camps, living quarters are not merely residential spaces—they are critical infrastructure supporting life safety and operational continuity. TLS delivers modular accommodation solutions engineered to meet the world’s highest standards, with robust design, advanced fire safety, and complete compliance with international maritime regulations including those from the International Maritime Organization (IMO) and the Safety of Life at Sea (SOLAS) Convention.

1. Structural Safety for Extreme Environments
TLS accommodation modules are constructed using high-strength weathering steel and standardized ISO modular dimensions, making them easy to transport and deploy rapidly. Designed to resist Category 12+ typhoons and seismic shocks, these units comply with ISO 1496 and the Container Safety Convention (CSC), ensuring safe, long-term operation in corrosive, high-humidity, and salt-laden environments common in offshore and remote regions.

2. A60 Fire Protection Compliant with IMO FTP Code
Fire risk is a critical concern offshore. TLS modules integrate A60-rated fire protection systems in accordance with the IMO FTP Code (Fire Test Procedures Code). The A60 classification ensures that walls, ceilings, floors, and doors can withstand 60 minutes of direct fire exposure without structural failure, giving personnel vital time for evacuation.
Key fire safety features include:
  • Wall Systems: Rock wool core panels with non-combustible coatings for superior thermal and flame resistance
  • A60 Fire Doors and Windows: Steel construction with self-closing mechanisms and certified fire seals
  • Electrical Safety: Optional flame-retardant cables and metallic conduits to reduce the risk of electrical fires

3. Compliant with SOLAS Safety and Emergency Standards
TLS integrates SOLAS safety requirements deeply into its design philosophy, with special attention to crew safety and emergency responsiveness.
  • Evacuation & Escape: Each module features clearly marked escape routes and independent emergency lighting systems for safe evacuation during power loss or fire
  • Emergency Systems: Smoke detectors, audible-visual alarms, and fire detection devices are integrated to provide early warning and rapid response capabilities

4. Smart and Customizable Interior Solutions
TLS supports full interior customization to meet operational and crew comfort needs. Options include:
  • Ergonomic furniture layouts
  • Tailored lighting schemes
  • Modular electrical systems
  • Smart environmental control and monitoring systems

5. Factory Acceptance Testing (FAT) for Every Unit
Every TLS accommodation module undergoes comprehensive Factory Acceptance Testing (FAT) before delivery. The testing includes structural inspection, full electrical energization, HVAC performance trials, and ventilation system checks. This guarantees each unit is delivered ready to use, fully operational, and safe.

Conclusion
Accommodation units are the lifeline of offshore and remote-site projects. At TLS, we uphold international standards and apply engineering excellence to deliver modular living solutions that clients can truly rely on—for safety, comfort, and peace of mind. We don’t just deliver containers—we deliver secure spaces built to protect life.

In extreme offshore environments such as oil drilling platforms, offshore wind farms, FPSOs, and floating work zones, functional containers—such as accommodation modules, laboratories, control rooms, and equipment enclosures—serve not only as essential units for work and living but also as dual safeguards for equipment safety and personnel protection. In these scenarios, safely lifting containers onto decks or vessels is a critical and often underestimated process.

To ensure lifting operations are stable, secure, and controllable, offshore containers must undergo rigorous lifting tests and obtain third-party certification. This process is not only a regulatory requirement, but more importantly, a vital safeguard for life and property.

1. What is a Lifting Test?

A lifting test simulates the real-world lifting conditions of a container before it leaves the factory. It thoroughly examines the structural strength, weld integrity, and the robustness of lifting points (pad eyes). The test is carried out according to classification society or industry standards and serves two main purposes:
  • To verify that the lifting structure can support the design load.
  • To ensure that the structure does not undergo permanent deformation or failure under extreme conditions.

2. Why is Lifting Test Mandatory for Offshore Containers?

(1) Mandatory Compliance with Standards
Offshore containers are governed by stringent industry standards such as:
  • DNV 2.7-1: Design, manufacture, and certification of offshore containers
  • ISO 10855: Offshore containers used in the oil and gas industry
  • EN 12079: European standard covering lifting equipment and structural requirements
All of these standards mandate that containers must undergo lifting tests and obtain valid certification before delivery.

(2) High-Risk Marine Environments Demand Zero Compromise
Lifting operations at sea are exposed to confined spaces, vessel motion, and unpredictable weather. Any failure in the lifting structure or pad eyes can result in equipment damage, loss of life, or catastrophic accidents. A lifting test ensures structural integrity and reliability under such conditions.

(3) Essential for Project Approval and Global Market Access
Oil & gas operators, EPC contractors, and classification societies routinely inspect lifting design and certified test results. Containers without certified lifting tests will be rejected from offshore sites.

3. How is a Lifting Test Performed?

TLS follows a standard process to ensure safe and certified lifting capability:
(1) Pad Eye Inspection & Structural Review
  • Pad eyes are manufactured using high-strength steel.
  • Welds are subjected to non-destructive testing (NDT) such as UT or MT.
  • The integration of lifting points with the frame is examined for structural integrity.

(2) Static Load Test
  • Load applied at 2 times the rated lifting capacity, as per DNV 2.7-1.
  • Container is suspended for at least 5 minutes.
  • Checked for any signs of deformation, cracks, or structural failures.

(3) Dynamic Load Test (if required)
  • Simulates lifting operations with movement and sway.
  • Monitors structural fatigue and elastic recovery under repeated loading.

(4) Final Certification
Upon successful testing, a certificate is issued by an accredited classification society (e.g., DNV, BV, LR, CCS).
This certificate accompanies the container upon delivery and is recognized by global offshore project stakeholders.

4. TLS Practice in Lifting Test Assurance

As a specialized manufacturer of offshore functional containers, TLS conducts lifting tests on every unit destined for marine environments. Our process includes:
  • Full compliance with DNV 2.7-1 or custom project specifications
  • On-site testing with professional lifting rigs and calibrated equipment
  • Third-party witness testing and traceable documentation
  • Issuance of globally recognized, valid lifting certificates

5. Conclusion: Safety Starts with Testing and Ends with Trust

Behind each seemingly simple lift lies a comprehensive evaluation of structural design, welding, material quality, and load handling capability. Only through a standardized and certified lifting test can every lifting operation be performed with confidence—establishing an unbreakable safety foundation for offshore operations.
