Charting Services

Having access to accurately mapped submarine cable routes has become essential following the increase in seabed usage from industries such as telecoms, renewable energy, oil & gas and resource mining.

Protecting cables by minimising unexpected human intervention

There are over 200 faults on submarine fibre optic cables annually, and 74% of those are caused by accidental third party activity such as fishing, anchoring, dredging or other marine user intervention.

Sharing seabed data with the relevant authorities and other seabed users in the form of cable awareness charts or flyers can help minimise that figure, ensuring other marine users are aware of the location of these important assets to avoid damaging them.

OceanIQ® can produce professional, branded cable awareness charts for issue by the client to authorities and vessel masters for this purpose. These charts can support a fishing liaison strategy to counter the most widespread cause of damage to cables.

For a wider reach, we can also set up and manage a dedicated website to host the charts in a convenient location. Please click here to view one of our cable awareness sites.

Customised GIS, custom cable charts, and installation chart updating are available to support the following:

  • Survey data from CAD based survey charts
  • Route engineering
  • Burial verification surveys
  • Integration of legacy data into a customised GIS GeoCable® format
  • Production of installation north-up and alignment sheets, burial graphs
  • Overview/location maps
  • Planning charts
  • Route position lists and cable crossing lists
  • Landing site diagrams
  • Seismic activity charts
  • International territorial boundary charts
  • Geo-referencing of aerial photographs and satellite images

Please click on the pins below to open up an example of the charts available.

Digital Cable Awareness Charts

Our web-based Cable Awareness Charts detail all the cable segments, landing points and countries that form part of a cable system.

Our interactive GIS provides accurate cable routes to other seabed users. By sharing cable locations, third party damage can be prevented and minimised for the long-term security and integrity of the connectivity they deliver across the globe, for cable owners and end-users.

Our branded cable awareness websites display all the relevant data along the  full length of a cable system. All charts provide the cable owner’s contact details and are freely available to download and use.

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...
