COOEC has completed fabrication of the jacket for Saudi Aramco’s CRPO149 project, marking a key milestone for the long-term agreement project handled by the company as the main contractor.

The structure was completed at Qingdao yard and prepared for transportation to the Middle East. The project represents the first full-scope EPCI lump-sum contract executed by COOEC for Saudi Aramco. The work scope covered engineering, procurement, fabrication, installation and brownfield modification involving topsides, jackets and subsea cables.

The completed jacket weighed nearly 1,000 tonnes and was loaded out using self-propelled modular transporters (SPMTs).

For the project, COOEC adopted a jacket turnover construction method combining horizontal fabrication with vertical assembly. According to the company, the approach was applied for the first time in China on this type of project to improve construction efficiency and reduce risks during both onshore construction and offshore installation.

Despite difficult weather conditions, including strong winds and lower temperatures, the fabrication team maintained the project schedule and completed the loadout on time. The company said the jacket design and construction phase was finalized within 11 months.

Localization for the project exceeded 95%, while execution efficiency and engineering quality reached the company’s targeted standards.

The completion further strengthens cooperation between COOEC and Saudi Aramco in offshore energy infrastructure projects.
