Pelagian’s expertise and specialist knowledge of subsea cable systems provides the perfect match for infrastructure engineering projects. We can contribute to key elements of the project life cycle, from initial design and feasibility, survey and risk assessment through to construction and system commissioning.

Case Study: Italy to Tunisia Power Cable Permit Study

Pelagian were contracted by a major international engineering consultancy to provide expertise on permits for a proposed HVDC power cable between Italy and Tunisia in the Mediterranean Sea.
The study researched the maritime jurisdictions of each of the countries crossed by the proposed cable and the permitting and regulatory requirements for the survey and installation of a subsea power cable.
The work scope also researched the environmental requirements at the landing points and coastal shelf areas and also stakeholder requirements for the crossing of a significant number of active telecom cables and oil/gas lease blocks.

Case Study: Isle of Wight Telecom Cable Route Study

In 2014 Pelagian were contracted to research a desk top cable route study for two new domestic fibre-optic cables between Portsmouth on the UK mainland and Ryde on the Isle of Wight.

The Solent was a challenging area for the study. The routes sympathetically considered the important coastal habitats and also numerous marine activities. These included fishing, commercial shipping, recreational boating and yacht races and the planned Portsmouth regional dredging campaign.

The two cable routes were chosen to minimise the impact of both natural and manmade hazards present in the Solent and provide safe and diversified routes between the UK and the Isle of Wight, protecting internet connectivity for the local population.
