Project details
The Challenge
Claxton was engaged to deliver a critical role in one of the largest decommissioning campaigns in Southeast Asia. The project involved supporting the removal of 36 offshore platforms across the Gulf of Thailand - a complex scope that included 32 conventional jacket structures and 4 tripod platforms.
Each structure presented unique engineering and logistical challenges, from managing aging infrastructure to ensuring safe and efficient dismantling in a busy offshore environment.
The Solution
The scope included complex cutting and soil removal operations. Claxton executed Diamond Wire Saw cuts on inbound and outbound risers at two levels, plus conductor cutting on selected platforms.
For four-legged jackets, Claxton’s proprietary Abrasive Water Jet Cutting (AWJC) technology was selected for its proven long-term performance and applied at two critical points: mid-water (jacket and pile) and below the mudline (piles only). To enable these cuts, the Soil Plug Removal Tool airlifted soil from inside jacket legs, providing access for AWJC up to 5 meters beneath the seabed.
The Result
In total, the campaign achieved 282 cuts using Abrasive Water Jet Cutting, 47 cuts with Diamond Wire Saws, and 140 successful deployments of the Soil Plug Removal Tool. These operations enabled the safe and efficient removal of 32 conventional jacket structures and 4 tripod platforms.
The project was delivered over 458 days with minimal non-productive time and consistently high operational standards. This success was driven by daily collaboration, open communication, and a shared sense of responsibility across all teams - ensuring that every stage of the process met the client’s expectations for safety, efficiency, and performance.
