Theresa May is set to announce support for an underwater engineering base in Aberdeen to boost the oil and gas industries.

The Prime Minister will use her speech at the Scottish Conservative conference to back industry plans to build a multimillion-pound centre "to bring areas of excellence in underwater technology together".

It is hoped the creation of an underwater hub will build on the country's expertise in subsea robotics, remotely-operated vessels and help the oil and gas sector diversify away from fossil fuels.

Announcing the Government's backing for a centre of excellence for the underwater industry, Mrs May is to tell the conference in Aberdeen: "It would bring areas of excellence in underwater technology together under a single commercial vision - creating jobs, boosting the local economy and cementing Aberdeen's place as an energy hub for offshore and renewables.

"Our subsea engineering sector already supports tens of thousands of jobs - 60% of which are based here in Scotland.

"It would help established businesses thrive and create new opportunities as the world makes the shift towards clean growth. Supporting industry, helping us in the fight against climate change and creating new skilled jobs and opportunities for people to get on."

Praising the "outstanding contribution" the oil and gas sector has made to the UK economy, Mrs May will add: "It has developed a world-class centre of expertise in the incredibly challenging conditions of the North Sea.

"The UK Government has done a lot to support the sector as the oil price has fluctuated over the last few years.

"Being a United Kingdom, with the world's fifth largest economy, gives us the broad shoulders to do that."

Companies will now be invited to submit business cases for the hub for the Department for Business, Energy and Industrial Strategy to review.

UK Government Business Minister Andrew Stephenson said: "As the UK continues to transition towards a low-carbon economy, the Global Underwater Engineering Hub can help the region rise to the challenge of this transition, helping to anchor the UK's expert engineering supply chain here in the north east of Scotland.

"It will build on the UK's position as a world-leader in underwater technology and skills, which can be exported around the globe in growing sectors like renewables and decommissioning."

Scottish Secretary David Mundell added: "Scotland is an exceptional place to do business and its engineering opportunities are world leading. The UK Government supports Scottish industry and that is why we are backing the underwater engineering hub in Aberdeen.

"The UK Government has shown time and again its commitment to the city's oil and gas sector and now we are investing in the blue economy to ensure the region continues to prosper with jobs, investment and innovation."
