Existing shareholder Foresight Group also participated alongside In-Q-Tel, the strategic investor for the US intelligence and defence communities and allied nations.

Sister company Rovco – which is also benefitting from the fundraise - delivers this technology into the energy transition space, mainly focused on its use for subsea surveys in offshore wind and oil field decommissioning.  The group’s existing customers include energy giants Iberdrola and SSE and ocean services provider, DeepOcean.

Vaarst’s technology is designed to substantially lower the costs of marine operations and present seabed information simultaneously to any device in the world in real time. At present, typical costs for a single service vessel working on a maritime asset can reach up to $10m per month, which is both labour and cost intensive. Vaarst’s technology can help reduce the numbers of people at sea, while improving the data insights gained from offshore robots.

The investment will allow the company to expand its pioneering work in the field of computer vision and data management, as well as supporting the group’s major globalisation plans. This includes expansion to Austin, Texas and Tokyo, Japan, as well as increasing its presence across Europe. Investors cited these growth ambitions as a major factor in the investment decision, identifying the significant opportunity within the marine infrastructure sector, which comprises 10% of all global infrastructure.

Brian Allen, CEO at Vaarst, said: “We’re delighted to have gained the support of some of the industry’s leading businesses and investors to help us execute on our vision – to change the way we conduct over the horizon robotic operations. In doing so, we will not only help the marine industries become safer and more profitable, but will make the investment case for the energy transition more attractive, accelerating the journey to net zero.

"When Vaarst was founded, we looked to bring the latest innovation to the marine survey sector to help drive efficiencies – making them quicker, safer, and more cost effective. As we’ve grown and developed, our technology has become increasingly advanced and its potential to transform other sectors has become ever clearer. “

John Bromley, Head of Clean Energy at Legal & General Capital said: “Our clean energy platform continues to grow, entering new sectors and supporting the growth of innovative new technologies. Rovco and Vaarst are exciting companies which will help further support the global energy transition by supporting the long-term integrity of maritime assets, reducing costs, improving safety and speeding up processes.

"We are excited by their huge potential internationally and the synergies this could bring as we look to the international expansion of our investment in renewable infrastructure such as offshore wind”
