DeltaStream, developed by Cardiff-based Tidal Energy Ltd, has become one of the first grid-connected demonstration devices worldwide to generate green, sustainable and predictable tidal power. The 400 kilowatt device weighs 200 tonnes and has a frame 16 metres long with a height of 18 metres. It also has a gravity-based foundation which sits on the seabed under its own weight without the need to drill or pile the structure into the seabed.
“The deployment of DeltaStream marks a significant achievement for all involved and Mojo is delighted to have been able to support the Tidal Energy team in reaching this important milestone” said Richard Parkinson, Managing Director of Mojo Maritime.
Mojo Maritime worked closely with Tidal Energy to develop the installation plan and manage the specialist services required to complete the works in the challenging tidal streams in the region. This included Dynamic Positioning (DP2) vessel operations, Remotely Operated Vehicles (ROV), hydrographic survey, heavy lift, cable operations and marine project management. The device was loaded off the quayside in Pembroke Port on Sunday 13th December by the offshore construction vessel ‘Siem Daya 1’ before making the short passage to Ramsey Sound for installation during a suitable tidal window.
Mojo Maritime Ltd is a subsidiary of James Fisher and Sons plc. The company specialises in project management, engineering and consultancy services for the offshore renewable energy industry, employing an experienced team of analysts, engineers, naval architects and master mariners. It has built a successful track record supporting multiple high profile projects in offshore wind, wave and tidal energy. In addition, Mojo actively develops a range of products geared towards reducing the inherent risks and costs of working offshore.
