Case Study Overview
With N-Sea Group needing a reliable partner for its critical cable repair project in the Irish Sea, they turned to Red7Marine for a turnkey solution. Red7Marine was responsible for the delivery of two jack-up barges, supporting tugs, a 220t telescopic crawler crane, accommodation, and catering service. This package enabled N-Sea to focus on its goals of completing the repair, safely and efficiently, under a tight programme. The repair works were completed within three weeks, with the barges returning to the Port of Mostyn for demobilisation.

The Challenge
Working with the N-Sea team in the initial stages of the bid, we devised a methodology utilising two assets, with our engineers handling all feasibility, floating and jacked stability, leg penetration assessments and RAMS. It was great to push the capabilities of the barges and end with a solution that worked for N-Sea and the project requirements.

The repair works were completed within three weeks, with the barges returning to the Port of Mostyn for demobilisation.
Dale McDonald, Operations Manager Subsea Cables commented: “When preparing and executing such complex projects as Principal Contractor, your supply chain and trusted Contractors play a vital role. Our dealings with Red7Marine have been positive throughout. Always willing to go above and beyond, to ensure the success of the project. The team at Red7Marine understood the complex nature of the scope and environment and were always quick to work with our project team to overcome challenges and find solutions.”
