Robot boat completes three-week Atlantic mission

Robot boat completes three-week Atlantic missionEssex-based SEA-KIT International’s 12m Uncrewed Surface Vessel (USV) ‘Maxlimer’ successfully returned to Plymouth on 14 August after 22 days of remote survey operations on Europe’s continental margin in the Atlantic Ocean.

Since late July the USV has mapped over 1,000km2 of ocean floor, controlled around-the-clock by SEA-KIT via satellite communications from its Remote Operation Centre in Essex. Notably, the uncrewed vessel returned to Plymouth with its fuel tank still around a third full.

The successful completion of this project is a major achievement for the British SME, clearly demonstrating the capabilities of its remotely controlled USV design in terms of over-the-horizon operation, endurance and ocean-going ability.

Peter Walker, SEA-KIT director of technology, said: “It has been a tense but exciting few weeks. The project’s overall aim was to demonstrate the capabilities of current technologies to survey unexplored or inadequately surveyed ocean frontiers and we have absolutely done that.

“It is a ground-breaking achievement to prove true over-the-horizon capability and the team are elated to have successfully pushed the boundaries of our USV design once again.”

Named UTAS (Uncrewed Trans-Atlantic Survey) and co-funded by the UK Space Agency through the European Space Agency’s Business Application programme, the project was originally planned to be trans-ocean. However, due to travel restrictions and other planning complications resulting from Covid-19, the original plan had to be aborted.

SEA-KIT worked collaboratively with a number of industry partners on the UTAS project. Fugro, Global Marine Group, Map the Gaps, Teledyne CARIS, Woods Hole Group and The Nippon Foundation-GEBCO Seabed 2030 project all played a part in its successful completion.

Jamie McMichael-Phillips, Seabed 2030 director, said: “The data gathered on this Atlantic voyage will be a valuable addition to the global seabed. More importantly, this is another milestone on the journey towards the development of the kind of scaleable, environmentally-friendly technology that we are going to need in order to reach our goal of mapping the whole of the world's ocean floors by the end of the decade.”

He added: “We are immensely proud of the SEA-KIT team and of what they have achieved in being able to operate an uncrewed vessel over the horizon. What began as a scientific challenge taken on by the talented members of the GEBCO-Nippon Foundation Alumni team became an award-winning technology that has now matured into a viable commercial company. This is exactly the kind of innovative ecosystem that GEBCO and The Nippon Foundation were trying to create when they launched Seabed 2030.”

The Nippon Foundation/GEBCO Alumni through Map the Gaps, with their global distribution, allowed for 24hr bathymetric surveying as they remotely operated the multibeam and ensured optimised data acquisition.

The proven ability to conduct remote survey operations with USVs has many beneficial applications across the offshore sector. For example, critical tasks such as trans-ocean cable route surveys, needed to meet the increase in demand for data communications, can be completed without risk to personnel and with significant savings on mobilisation and operational costs when compared to executing the same task with crewed vessels.

Graham Turnock, UK Space Agency chief executive, summed up how USVs are set to redefine offshore operations: “On its 22-day mission the Maxlimer vessel used satellites in the sky to show us what we can do under the sea.

“Robot boats could radically change the way we work at sea and this project, backed by the UK Space Agency, has given us a unique window into the future potential of satellite-enabled maritime operations.”
