3C Metal USA has been awarded a contract by Noble Corporation to carry out a full managed pressure drilling (MPD) system integration onboard the Noble Discoverer semi-submersible drilling rig. The scope covers all aspects of the integration, including survey, design, supply, fabrication and installation.

The installation includes a structural tower to support the new MPD manifolds, high-pressure and low-pressure piping, and associated electrical and hydraulic systems. The project also involves the integration of a new integrated riser joint (IRJ) and MPD reeler, alongside the relocation of the drill line spoolers to the drawworks shed.

Fabrication of the structure and low-pressure piping, representing the majority of the fabrication scope, was completed in South Africa in mid-July. High-pressure piping fabrication was carried out at 3C Metal’s Houston workshop and is now complete.

The installation phase is currently underway in Curaçao. The team will focus on installing more than 45 tonnes of structural steel and over 15 new pipelines throughout the rig. A team of 50 personnel is expected onboard during the rig’s out-of-service period, which will span more than 65 days. Completion of the installation is projected for Q4 2026.

Through this project, 3C Metal USA demonstrates its capability to deliver complex drilling system integration projects, combining engineering, fabrication and installation expertise to support the operational requirements of its long-standing client, Noble Corporation.
