Offshore Oil Engineering Co., Ltd. (COOEC) has signed a long-term Engineering, Procurement, Construction, and Installation (EPCI) contract with Thailand’s national oil company PTTEP for the Bundled Phases 4 Project, valued at approximately USD 800 million. The award represents the largest single EPCI contract ever obtained by a Chinese offshore contractor in Southeast Asia, setting a new benchmark for the sector.

The contract marks another milestone for COOEC in the Asia-Pacific market following its previous award of the PIC Phase 4 EPCI project in 2024.

The Bundled Phases 4 project is located in water depths of about 60 to 80 meters and will be executed under a Long-Term Agreement (LTA) framework between PTTEP and its selected contractors. The scope of work includes the fabrication and installation of new wellhead platforms and jackets, transportation and installation of existing topsides, installation of risers and pipeline end manifolds (PLEMs), subsea pipeline laying, and modification of existing offshore platforms.

As the general contractor, COOEC will deliver a full EPCI solution covering project management, detailed engineering, procurement, fabrication, transportation, installation, and pre-commissioning.

COOEC has begun mobilising an international project management team and consolidating its global resources to carry out the project. The company stated that execution will be managed in accordance with its refined, standardised, and professional project management practices to ensure safe, high-quality, and efficient delivery.
