DeltaStream Installation

Mojo Maritime delivers specialist marine project management services for the first Welsh tidal energy generation project. 

Completion of installation means DeltaStream is now one of the first grid-connected demonstration devices worldwide.

Leading tidal energy marine operations contractor Mojo Maritime Ltd (Mojo), part of James Fisher and Sons plc, led the installation of the first Welsh tidal energy generator for Tidal Energy Ltd (Tidal Energy).

Working closely with Tidal Energy, Mojo developed the installation plan and managed the specialist services required to complete the works in the challenging tidal streams experienced in the region. This included Dynamic Positioning (DP2) vessel operations, Remotely Operated Vehicles (ROV), hydrographic survey, heavy lift, cable operations and marine project management.

Chris Williams, Development director of TEL added:

“We have worked closely with the local supply chain and contractors to install the necessary infrastructure to make this project happen. We would like to thank Mojo for their hard work, resilience and support which has helped us reach this pivotal milestone.”

Completion of the installation, in Ramsey Sound, Pembrokeshire, means that DeltaStream will become one of the first grid-connected demonstration devices worldwide to generate green, sustainable and predictable tidal power. 

DeltaStream, developed by Cardiff-based Tidal Energy, weighs 200 tonnes with a frame 16m long and height of 18m. The 400kW demonstration device 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 patented DeltaStream device was loaded off the quayside in Pembroke Port on Sunday 13 December by the offshore construction vessel ‘Siem Daya 1’ before making the short passage to Ramsey Sound for installation during a suitable tidal window.

Managing director of Mojo Maritime, Richard Parkinson said:

“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.”
