The Challenge
With no access to heavy lift vessels, jack-up rigs and with strict platform constraints, the client required a solution which could overcome limited deck space, restricted load capacity, and with a the need to minimise offshore personnel. Thus, requiring a fully modular, rigless recovery system that could execute wellhead recovery operations without disrupting platform infrastructure.
The Solution
Claxton delivered a fully engineered recovery system built around the Lightweight Recovery Deck (LWRD); a modular, rigless solution specifically tailored for compact, aging platforms. Following a detailed FEED study, the LWRD was adapted to suit the platform’s space and load limits, enabling safe deployment without the need for HLV / Rig setup. The system was paired with a suite of specialised tooling to ensure precise and controlled execution:
The Result
The operation was completed safely and successfully, exceeding performance expectations:
This project demonstrated the adaptability of the Claxton LWRD system and tool suite to meet complex offshore decommissioning challenges while maintaining operational efficiency, safety, and project integrity.
Utilising the LWRD eliminates the need for a Heavy Lift Vessel, Accomodation Workboat or additional marine support vessels.
By delivering conductor recovery operations independently on the unit we can reduce offshore personnel requirements, both of these reduce project time and day rate, providing a substantial cost-saving for the Operator.
