SURF Decom Case Study
Retrieving FPSO SURF with Helix
Safe SURF recovery solution
Helix Robotics Solutions had a bare vessel and 7 cables, umbilicals, flowlines and jumpers connected to an FPSO pending retrieval. They turned to MDL for the complete solution, including expert support 24/7.
MDL provided a complete equipment spread, comprising of a Second-generation Reel Drive System, level winder, 4-track tensioner with Failsafe Grip System and deck deflectors. The spread was used for spooling of the product under tension onto two installation reels, also supplied by MDL. It was operated by MDL's expert personnel, backed up by the onshore engineering team.
“The challenges on this project revolved around the age and fragility of the products, moving schedules, as well as Covid-related personnel restrictions," said Paul Marshall, MDL Project Engineer. "We worked closely with the client to optimise the execution of the on-board operations, including change to tensioner squeeze settings and pads changeouts to suit the different products. Our offshore personnel supported the client’s team with their knowledge and expertise in flexible product handling and management of change, reinforcing safe and efficient execution for a successful completion of this project.” Following the offshore execution, the products were safely transpooled off the reels onshore.
