The world’s biggest and deepest pool for testing the latest underwater technology, helping advance subsea robotics and even training astronauts is being planned in Cornwall.

The £150 million Blue Abyss facility will be the world’s leading extreme environment research, test and training centre serving the offshore energy, marine, defence and space sectors, and will be created at the Aerohub Enterprise Zone at Cornwall Airport Newquay.

Blue Abyss is expected to create 160 jobs, pump £50m of build costs into Cornwall during its 18-month construction, and generate £8m annually for the local economy.

With the world’s first commercial astronaut training centre, other markets for the facility span offshore energy, maritime defence, ocean ecology, human life sciences and commercial diving. It will help in the further development of remotely operated subsea robots and mini submersibles.

The centrepiece of Blue Abyss is an aquatic centre featuring a 50m by 40m stepped pool with a 50m deep shaft. The pool holds over 42,000 cubic metres of water – the equivalent of 17 Olympic size swimming pools or 168 million cups of tea – making it the largest and deepest indoor pool in the world.

Blue Abyss is the brainchild of ex-forces diving instructor and management consultant, John Vickers, and has the support of British astronaut Major Tim Peake, who sits on the Blue Abyss Advisory Board.

Tim Peake said: “I am proud to be part of the Blue Abyss team and I am delighted to see the project take such an important step forward with today’s announcement.

“Cornwall is the perfect home for Blue Abyss, a region with great potential for its space, aerospace and renewable energy ambitions. This project will join Goonhilly Earth Station and Spaceport Cornwall as significant national assets It will create a deep sea and space research, training and test facility, as well as fantastic educational resource, helping to widen our knowledge of how humans and technology can function in extreme environments, for the benefit of people and the planet.”

John Vickers, Chief Executive of Blue Abyss, said: “We’re planning a globally unique facility with a wide range of potential uses that tap into so many of the industries that Cornwall and the South West are known for. Blue Abyss will be a huge research asset for aerospace, offshore energy, underwater robotics, human physiology, defence, leisure and marine industries, and a fantastic education centre for children and university students.

“Cornwall already feels like our natural home and we’re delighted to have received such a warm response.”

Steve Double, MP for St Austell and Newquay, said: “Blue Abyss is a perfect example of the sort of facilities for which the UK should be renowned and I’m delighted the project has chosen Newquay as its home. It will foster many of Cornwall’s emerging industries, creating skilled, well-paid jobs and collaboration across industry, research and education.”

And Mark Duddridge, Chair of the Cornwall and Isles of Scilly Local Enterprise Partnership (LEP), said: “Blue Abyss has the potential to become an iconic project for Cornwall and a genuine world-class resource. It fits perfectly with our local industrial strategy to create quality jobs in growth industries like offshore renewable energy and space.”
