Submarine Cable System Expertise

Pelagian offers comprehensive expertise in the planning, design, and construction of submarine cable systems. With over 25 years of industry experience, our consultants support every phase of your project, delivering the technical and commercial insight needed to ensure success.

Cable Route Engineering

Our route engineers bring decades of experience in the design, planning, survey, and installation of submarine cables. This expertise spans a wide range of sectors—including telecommunications, renewable energy, offshore power, and oil & gas—and covers everything from short domestic links to large-scale transoceanic and multi-country networks.

Cable Route Studies

Pelagian’s cable route studies are a vital desktop resource for early-stage planning and route selection. These studies assess both natural and manmade hazards, as well as regulatory and environmental considerations along the proposed route.

We draw on a wide range of in-house and commercial databases, academic research, and industry standards. Key data includes seabed bathymetry, sediment types, oceanographic conditions (currents, tides, meteorology), and human activity such as fishing, shipping, and other seabed uses.

As part of the study, we also conduct site visits to evaluate potential beach landing points, assess terrestrial infrastructure, and identify nearby cable landing stations. We facilitate engagement with regulatory bodies, environmental stakeholders, and commercial interests to support a smooth project path from concept to construction.

Risk Management and GAP Analysis

Pelagian are leading industry experts in subsea cables, supplying a comprehensive risk management approach to cable projects at all stages of the life cycle. This risk management of subsea cable engineering encompasses a technical and commercial review of the project as a means of classifying how well a product, dataset or solution meets the needs of the project.

The GAP Analysis is used to highlight areas of deficiency or omission, where additional information would provide a better end product. Pelagian relies on its broad knowledge base and the practical expertise of our specialist consultants to identify where design, manufacturing, survey and installation can be improved to the benefit of the project.
