en.Wedoany.com Reported - T12 Engineering has completed the assembly and shipment of a 60-tonne gravity-based subsea structure, which will be installed in the Norwegian Sea to support critical mission subsea equipment. Designed for an independent Norwegian oil and gas operator, the structure departed from the port of Immingham, UK.

The project was delivered under an engineering, procurement, and construction (EPC) contract, managed by T12 Engineering. The company recently opened a new office in Oslo to expand its operations in Norway. Covering an area of 59 square meters, the structure was designed with technical, operational, and commercial requirements in mind, ensuring long-term reliability under harsh offshore conditions.

Initially adopting a modular approach, the structure can be transported using standard containers, and is adaptable for reuse in multiple subsea application scenarios in the future. Prior to shipment, the structure was fully assembled at the quayside. T12 Engineering stated that throughout the concept, detailed design, and manufacturing phases, close collaboration with manufacturing partners focused on optimizing manufacturability, improving material efficiency, and controlling costs, while meeting all subsea deployment requirements.

Graham Melroy, Director of T12 Engineering, noted that the successful assembly and shipment of the gravity-based structure represents a significant achievement for all parties involved and is one of the largest projects delivered by T12 Engineering to date. The company added that all engineering, manufacturing, assembly, and loading activities for the project were completed without any lost time injuries.

Once installed, the structure will meet the operator's quality, health, safety, and environmental requirements, as well as relevant DNV and NORSOK standards. T12 Engineering also delivered a documentation and intelligent data package, ensuring full traceability of information across the design, manufacturing, and testing phases.
