A human-powered submarine built by university students has received a professional makeover from the 3M Automotive Refinish Centre ahead of the European International Submarine Races.

3M is sponsoring the WarwickSub team and spent five days stripping, masking, priming, curing and painting the single-person, pedal-powered vessel a grey, 3M red and black, to prepare it for the competition in July.

“It’s not often we get to work on a human-powered submarine, so we really enjoyed putting our skills and products to the test," said 3M applications engineer James Cavalot. "We’re really pleased with the end result, which we hope will help the WarwickSub team to stand out in the competition.”

Good looks

The technology company took on the task of making HPS-Godiva 4 the best-looking contender, having sponsored the WarwickSub project for the past five years, providing services, products and expertise for each successive team.

Ahead of the ISR 2017, 3M had carried out extensive work – including filling, sanding, polishing and painting – on the hull of last year’s entry, HPS-Godiva 3. The hull was made using a resin filled with 3M glass bubbles to create maximum buoyancy and the entry went on to earn the 2017 WarwickSub team three awards.

The hull held up so well that this year only the new paint job was needed, giving the engineering undergraduates more time to focus on the submarine’s internal systems.
