The work is to begin in April and will involve Neptune working with prime contractor, Mermaid Marine Services, to install two sleeves to strengthen a jacket leg on a platform in 80m of water.

Neptune said the installation would increase the maximum topside load of the platform to incorporate new accommodation facilities.

The welding phase of the project, using Neptune’s NEPSYS technology, is expected to take about two weeks to complete.

Neptune managing director Christian Lange said the NEPSYS technology offered “substantial” cost savings and improvements over conventional maintenance practices.

“The portability of the technology ensures it can achieve a permanent repair solution in situ that is extremely cost effective, equal to dry weld standards and internationally class approved,” he said.

“On projects such as this where topside loads are increased, critical structural components on the jacket substructure sometimes require reinforcement and the NEPSYS welding technology is perfectly suited to this purpose.”
