Informing sound engineering solutions from the very start of a cable installation project
A DTS should detail all the influences on cable route safety, solutions for the environment encountered as well as specifying the amounts of submarine cable and the plant required to build the system.
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, are long standing Executive Committee members of the International Cable Protection Committee (ICPC) and European Subsea Cable Association (ESCA), and members 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”.
Engineering information which forms the blueprint for successful cable installation
We create comprehensive route position lists (RPLs) and straight line diagrams (SLDs) which detail the position and all aspects of the cable route such as the cable plant (branching units, repeaters, joints, beach manholes), cable lengths, armour types, transitions, slack, water depths, cable and pipeline crossing points, and maritime boundaries.
The RPL and SLD provide the definitive cable and plant quantities for manufacture, system integration and installation.
We ensure the route is designed in harmony with the planned installation methodology and burial tools, making sure that when the cable is installed the offshore teams have a route and cable engineered to produce a quality result.
Gulf 2 Africa (G2A) connecting Oman to Africa via a 1,450km repeater system
OceanIQ completed the route engineering with the information gathered from the marine survey and our Desktop Study, to successfully install the cable connecting Salalah, Bosaso, and Berbera.
BT Highlands and Islands, Scotland – route engineering for the 20 inter-island cables connecting the west coast and Orkney in Scotland
This project involved the engineering design for 40 shore ends and cable routing through some remote sites with challenging geological and tidal current conditions. OceanIQ also managed the route survey and burial assessments for these 20 cable routes.
Uninett system, Svalbard – route engineering for a two segment, 500km system connecting Longyearbyen to Ny-Ålesund in the Arctic Circle, the most northerly commercial cable system in the world.
This project involved overcoming the specific engineering challenges posed by icebergs and shore based ice.
Celtix Connect, Irish Sea
Route engineering for the cable connecting Dublin to Anglesey in Wales
OceanIQ’s route engineering team use the latest bespoke GIS software, both the internally developed GeoCable® and the industry leading MakaiPlan software.
Leveraging one of the largest datasets of marine cable faults in the world to provide peace of mind
Combine this with our intrinsic knowledge of cable installation and maintenance gained from being part of Global Marine Group, and we offer the very best intelligence for your projects.
The report uses anonymised fault data to characterise the risk environment for new cables based on actual faults on existing and out of service cables in that region.
This provides confidence at both a commercial and technical level that a new cable system has been designed with complete knowledge, from historical data, of the real risks it faces and that all possible steps have been taken to mitigate those risks.

Discovering the root cause for reoccurring or unexpected faults on in-service cables to improve system reliability
In many cases these challenging environments will only have come to light after the installation of the cable.
With an unrivalled understanding of cable fault causes, OceanIQ’s Cable Protection Assessment (CPA) uses all of the information available about an in-service cable system to describe the potential root cause of faults and propose solutions for preventing them in the future.
