Desktop Study

A DTS should detail all the influences on cable route security, solutions for the environment encountered, as well as specifying the amounts of submarine cable and the plant required to build the system.

Driving the Sector

Working together with our peers to drive positive industry change is an integral part of the work that we do as a business. OceanIQ’s parent company, Global Marine Group, is a long-standing Executive Committee member of the International Cable Protection Committee (ICPC,) and European Subsea Cable Association (ESCA), as well as being a member of the North American Submarine Cable Association (NASCA).

All our Desktop Studies comply with ICPC Recommendation No 9, ‘Minimum Technical Requirements for a Desk Top Study’.

A technical reference for the entire project, and throughout the life of the cable system

OceanIQ’s, DTS will detail factors likely to influence all subsequent activities – from survey through to installation, and then throughout the system’s operations and maintenance lifecycle.

Our experienced team of route engineers will:

  • Visit potential landing sites to assess the engineering requirements, then meet with local representatives of relevant marine authorities and visit industry representatives and other entities whose actions may affect the integrity of the cable (e.g., fishing, shipping, planning, and port authorities).
  • Research bathymetry, seafloor and shallow seabed lithology, currents, weather, seismology, tides, permits, other seabed users, fishing, and shipping.
  • Identify areas of potential difficulty for survey, installation and subsequent maintenance.
  • Investigate and detail environmental and cultural factors relating to the cable route, highlighting relevant statutes and regulations of the various authoritative bodies, including reflecting upon the impacts and potential risks of climate change.
  • Identify possible sources of risk to the cable – and the extent of that risk for the cable system. This includes an analysis of faults on existing systems nearby from OceanIQ’s extensive database. This data can also be supplied in a stand-alone Cable Fault Analysis
  • Identify permits, licences and other regulatory requirements necessary to install the cable and for the cable to remain in situ along the proposed route.
  • Recommend routes that do not conflict with existing subsea infrastructure.

Determining reliable cable ampacities for marine high voltage cables.
Posted: 11/03/2025

Determining reliable cable ampacities for marine high voltage cables.

Determining reliable cable ampacities for marine High Voltage Cables is currently the subject of significant industry and academic reassessment in order to optimise the operation (ampacity), design (cross-sectional area) and subsequent efficiency, longevity, CAPEX and profitability of both submarine power cables and their dependencies (Enescu et...
