Ocean tidal streams are one of the key sources of clean’ energy still to be fully commercialised.  For the UK alone they could provide up to 16% of the nation’s total electricity requirement and are an essential part of helping to meet carbon emission reduction targets.

However, up until now, the problem has been the lack of a cost effective and practical tidal turbine deployment and maintenance system that can meet this challenge.                              

Triton - the multi-megawatt tidal turbine platform that brings the cost of installation and maintenance of tidal energy turbines below that of offshore wind.

The ‘Triton’ Semi-Submersible Turbine (SST) concept is designed for deep water, such as the 60m deep Pentland Firth - too deep to mount turbines on towers to the seabed economically and too rough for surface floaters to survive.

Instead, the turbines are mounted on semi-submersible spar buoys tethered to the seabed gravity anchorages by a swing-arm

A key feature is that the turbines use technology and components developed from the wind industry, that already exist and that have been developed over the last 20 years. It is only the support structure that is truly new and innovative.

This site explains the resource available, the principles behind the turbines, how they can be installed, maintained and removed, and what the costs could be. This service is intended for education on tidal energy in general, and on the Triton concept in particular.

The TidalStream ‘Triton’:

• can be equipped with up to 10MW of turbine capacity from a range of turbine suppliers
• is simple to install, maintain and remove in fast tidal races
• provides easy access in a wide range of conditions for routine maintenance and unscheduled repairs with minimal  downtime
• is designed to survive the incredible power of the sea in all conditions
• provides a highly cost-effective and efficient turbine deployment system.
