Marine Power Systems (MPS), a Swansea-based wave energy developer, has completed the testing of the prototype pump for its WaveSub wave energy converter.
The project has been part-funded by the European Regional Development Fund through the Welsh Government, with MPS receiving a Â£2 million grant in October 2015.
The pump was deployed in the pickling pond, a tidal lagoon in the Pembroke Port prior to being recovered for testing. The aim of the pump testing was to determine whether any biofouling or corrosion affected the performance of the pump, the company explained.
The testing was conducted by Severn Subsea Technologies (SST). SST conducted a series of tests to ascertain its performance, including measuring flow rates pre- and post-deployment at sea.
A critical aspect of the prototype pump testing procedure was to investigate whether the pump could maintain the required flow rates in operation at sea. This is required to ensure the safety and reliability of MPSâ WaveSub device, which is due for deployment this year.
MPSâ WaveSub will provide a renewable energy source through harnessing the energy from ocean waves.
Dr Gareth Stockman, co-founder and managing director of Marine Power Systems, said:
âMarine Power Systems is hugely grateful to the Port of Milford Haven for its support and assistance through its Pembroke Port site which has aided the deployment and installation of the pump, and also to Severn Subsea Technologies for its expertise in the field.
âWe are reaching some exciting and important milestones as we work towards completing all the necessary procedures required to ensure the successful deployment of the WaveSub device. We are pleased with the positive results from recovering the pump prototype and are optimistic about upcoming testing processes we will carry out ahead of deployment of our quarter-scale WaveSub device.â
Natalie Britton, director of operations and commercial at Pembroke Port, said:
âWe are confident that the cluster of engineering skills, combined with excellent port facilities and an unrivalled marine environment off the Pembrokeshire coast, makes Pembroke Port the ideal location for the developing marine renewable sector.
âPembroke Port is a hub where everything from design and testing to manufacture and ongoing maintenance can be carried out, all within close proximity. It is a centre of excellence. In this case, Pembroke Portâs historic pickling pond offered a completely sheltered, secure marine environment for MPS to test components at variable water depth. Itâs been great to be able to help Marine Power Systems add value and confidence to its innovative design.â
