Offshore Platform Turnaround and Brownfield EPC Delivery

Brunei Shell Petroleum contracted TendrillWood, a joint venture between Wood and Tendrill Sdn Bhd, to complete a brownfield engineering, procurement, and construction turnaround campaign across three offshore operating platforms. The cooperation combines brownfield project governance with regional fabrication and offshore installation capabilities to support the operator's ongoing asset rejuvenation program.

Industrial Context and Operational Challenge
Offshore energy infrastructure requires periodic brownfield intervention to mitigate mechanical wear, clear process bottlenecks, and integrate new production tie-ins without compromising structural stability. Complex marine logistics, simultaneous operations, and severe offshore weather conditions require coordinated asset management frameworks. Integrating engineering oversight with localized construction resources ensures schedule reliability during critical facility outages.

Technical Scope and Division of Responsibilities
TendrillWood executed an integrated work scope spanning piping replacement, structural modifications, mechanical overhauls, electrical adjustments, and instrumentation calibration. Engineering teams conducted corrective maintenance, resolved process debottlenecking, and executed advance riser tie-ins to expand fluid handling capacity.

Wood managed design engineering, process safety integration, procurement governance, and project management systems, deploying technical subject matter experts from regional offices. Tendrill Sdn Bhd contributed domestic fabrication infrastructure, logistics coordination, and direct field workforce deployment. The integrated framework centralized maintenance readiness planning, technical quality assurance, and mechanical completion protocols prior to offshore mobilization.

Implementation and Field Execution
The turnaround campaign was deployed across three offshore platforms using dynamic scheduling models to accommodate adverse offshore weather disruptions. A multidisciplinary field team of 600 personnel completed offshore mechanical execution, loop testing, and system pre-commissioning. TendrillWood employs roughly 400 core personnel, maintaining a 70 percent domestic workforce across engineering, turnaround planning, and offshore operations.

Performance Metrics and Asset Integrity
The turnaround concluded with zero punch-list items, meeting contractual schedule and budget targets. The offshore campaign recorded 248,800 incident-free working hours, logging 816 safety observations and three operational emergency drills to maintain site safety integrity. The structural modifications and process line tie-ins re-established original design margins, stabilizing production throughput and extending platform design life.

Strategic Infrastructure Impact
"The turnaround demonstrates TendrillWood’s delivery model in Brunei. It builds on Wood’s in-country presence and local project delivery expertise from the BSP Rejuvenation project, supported by regional and global SMEs, and combines this with Tendrill’s fabrication and installation capability and skilled local workforce." - John Campbell, Senior Vice President Asia at Wood.

The technical integration of specialized brownfield EPC engineering with local marine fabrication supports sustainable operations across Brunei's offshore energy assets, preserving long-term asset integrity and operational continuity.
