    Hat-trick of awards for WarwickSub team

    A human-powered submarine built by students at the University of Warwick picked up three awards at the International Submarine Races in Washington DC.

    • The International Submarine Races were held from 25-30 June and the WarwickSub team of engineering undergraduates picked up awards for the Best Use of Composites and the Best Design Outline. HPS-Godiva III was also placed third for speed in its category.

      To give the submarine the best chance of success in the races and make it the best-looking contender, Godiva III’s 2.8-metre-long hull spent two weeks at 3M’s state-of-the-art Automotive Refinish Centre in Atherstone, Warwickshire, in May.

      3M engineering technician, Clive Cooch, and 3M applications engineer, James Cavalot, dedicated their full attention to the submarine during its stay, working on the project full-time.

      They began by filling in small holes in the bodywork using the 3M Dynamic Mixing System to give a high-quality finish. Next, Clive and James smoothed down the surfaces using 3M™ Cubitron II™ abrasives that feature precision-shaped grains, helping them to slice cleaner and faster.

      Using the 3M™ PPS™ Paint Preparation System, the pair then applied an undercoat of primer and used 3M abrasives to remove any final imperfections before spraying the hull in dazzling blue and orange paint.

      To achieve the ultimate finish, Clive and James polished the vessel using products from the 3M™ Perfect-It™ Finishing Materials range.

      The recycled carbon fibre hull itself was made using a resin incorporating 3M glass bubbles to create maximum buoyancy and reduce the weight of the submarine and 3M™ Scotch-Weld™ EPX Adhesive DP490 was used to fix aluminium mounting plates, which will hold some internal components, onto the hull.

      3M also provided the team with personal protective equipment to use throughout the project, including respirators, safety eyewear, coveralls and ear plugs.

      At the Washington races, the WarwickSub team won the Best Use of Composites award for the innovative use of recycled carbon fibre in the hull and its design report earned the top prize for Best Design Outline. In addition, Godiva III reached a top speed of 2.52 knots, the highest speed registered by any WarwickSub team, earning third space for speed in its category.

      Michael Andronicou, WarwickSub business development manager, said: “We are delighted that we were also the best team from the UK in terms of the number of awards won and the speed of our submarine.

      “3M’s support has been paramount to the success of this year’s WarwickSub Godiva III. Thanks to the provision of 3M materials and technical support, as well as the amazing paintwork, our submarine stood out from all the other entries and received countless compliments.”

      Last year’s WarwickSub team – also sponsored by 3M – won the Best Design Report award at the European International Submarine Races, held in Gosport.
