Longitude Engineering, aspecialist engineering consultancy and part of the London Offshore Consultants (LOC) Group, has developed a cost effective decommissioning barge concept for the removal of small oil and gas platforms for PTT Exploration and Production (PTTEP), a subsidiary of the Thai state owned oil company.
The primary aim of the works was to develop a viable and cost-effective alternative to conventional reverse installation through the use of heavylift crane barges, for the removal of the topsides and jackets. The focus being the removal of 90-100 of PTTEP’s minimum facilities platform assets in the Gulf of Thailand, which have topside weights up to 800 tonnes and jacket dry weight up to 1,000 tonnes.
