A best-in-class cable deployment control software MakaiLay was commissioned on the cable laying vessel Giulio Verne in November 2017 by the Prysmian Group, the world leader in the energy and telecom cables and systems industry. Giulio Verne is a DP2 cable laying vessel built to tackle the most challenging worldwide subsea operations and interconnections. It is expected that MakaiLay with its power-cable-specific module will be used by Giulio Verne when it starts working on the North Sea Link installation. North Sea Link is a subsea power cable interconnector between Norway and UK and will be the longest subsea interconnector in the world upon completion in 2021.

“We made it our priority to extend our popular real-time submarine cable installation management software to submarine power cable installations and we are excited that an industry leader like Prysmian Group has decided to use our software,” said Dr. Jose Andres, President Makai Ocean Engineering, Inc. “We have added specific tools to satisfy the unique demands of power cable installations and we will continue to enhance the software as we receive feedback from our installation partners.”

imagery overlay on the terrain in the background, as is shown here.

MakaiLay accurately calculates the shape of the cable in the water column and the condition of the cable near the touchdown point and displays this information in real-time. To accomplish this, MakaiLay integrates data from all the typical instruments available on a vessel, such as navigation (GPS, Gyro), cable data (tension, cable counter & length), currents (ADCP), and bathymetry. This information, together with a 3D dynamic model of the cable provides key information to the installers to properly install the cable along the route with the proper tensions.

The Power cable module includes a collection of tools that were developed for addressing specific issues faced by power cables during installation. Some of the tools included are:

  • Span Analysis tool to analyze the risks of cable free spans along the route.
  • Heave Analysis tool to understand the cables’ response to various sea-states.
  • Auto-Tension feature to maintain proper bottom tension during installation.
  • Tide height correction feature to account for large sea surface height changes.
  • Integrating measurements from touchdown monitoring tools (e.g. ROVs).
