Liberty Industrial has completed the onshore deconstruction and recycling of the Santos Campbell platform on behalf of McDermott International Ltd.
The project featured the Roll-On-Roll-Off procedure of the oil platform using Self-Propelled Modular Transporters (SPMTs) at the Australian Marine Complex Common User Facility (AMC CUF).
“The decommissioning of the Campbell platform exemplifies Liberty Industrial’s ability to tackle the intricate nature of onshore decommissioning, setting a benchmark for excellence in a rapidly growing industry sector,” said Jed Van Iersel, decommissioning manager at Liberty Industrial.
Van Iersel added that it highlighted the company’s ability “to meet all stakeholder requirements” and to handle complex marine operations.”
Following the offshore removal by McDermott, the Santos Campbell platform arrived at Port Henderson in three unique structures via barge.
These structures were safely transported via SPMTs to the onsite deconstruction yard for disposal and recycling.Liberty Industrial executed the Roll-On-Roll-Off procedures in just five days, following six months of meticulous planning with leading in-house and subcontractor engineers.
The deconstruction posed significant logistical challenges, the company added in a statement.
Each structure, the heaviest weighing over 600 tonnes, required a bespoke handling plan to ensure safe and efficient transfer from the barge to the decommissioning site, addressing various water displacement considerations and tight port schedules.
The remaining onshore deconstruction and recycling programme was completed on budget, on time, and with exceptional stakeholder satisfaction in 57 days, the statement noted.
Located in the Varanus Island hub, the Campbell Platform removal was contracted to McDermott in 2023, who then engaged Liberty Industrial for the task of deconstruction and waste recycling management.
All structures were deconstructed using suitable demolition excavators, with demolition of taller structures achieved by high reach excavators, oxy-cutting from EWP to pre-weaken structures before final induced collapse, the Liberty Industrial statement noted.
The materials from these structures were then downsized and moved to the processing area for segregating and processing using hot oxy-cutting and cold mechanical shearing, achieving a 99.5% recycling rate.
“We are extremely pleased with our ability to manage the complexities of the project by expanding our capabilities to include marine offloading operations and set a new benchmark for onshore decommissioning in Australia,” said Warwyck Smith, Decommissioning Project Manager, Liberty Industrial.
“We look forward to expanding on our already established and growing presence as a subject matter expert in onshore decommissioning in Australia and internationally.”
