MDL has supported DOF on back-to-back SURF projects in two West African countries.

On the first project offshore Angola, MDL supplied its Generation 3 Reel Drive System, high-capacity Horizontal Lay System (HLS-400), 4-track tensioner and 55Te A&R winch with associated wire package for the installation of a 10” water injection flexible jumper in approximately 1,700m water depth. The project was executed using DOF’s I-Class vessel Skandi Installer, enabling MDL to deploy a full flex-lay spread optimised for the deep-water jumper installation.

The follow-on shallow-water scope in Congo covered the installation of flexible lines and composite submarine cables from 16 reels. The MDL Generation 3 RDS and 4-track tensioner were deployed alongside HLS-200 – a compact package to allow more space on deck to accommodate the larger number of reels and products on the mission. The 55Te unit from MDL’s Winches & Lifting Solutions was supplemented by its two 15Te tugger winches.

Scott Manson, Project Manager at MDL, said:
“I’m proud to see these two back-to-back projects complete as they extend our track record with DOF in West Africa. After years of working together across the region, we have become highly efficient at identifying the best vessel and equipment combinations for each individual scope – and this back-to-back campaign is a great example.

“While the two projects shared core elements of the flexlay spread, the handling requirements differed between the deep-water Angola installation and the shallow-water Congo scope. Being able to deploy alternative Horizontal Lay System configurations, while maintaining continuity in the wider spread and vessel selection, allowed us to adapt efficiently between projects – evident in completing the second scope ahead of schedule.

“This campaign underlines the value of MDL’s portable flexlay systems and reflect the confidence clients place in our ability to support challenging offshore operations across the West African region.”
