Triton 6 (up to 10MW output in deep coastal sites) shown in the operating position in the foreground and maintenance position in the background.
Tidal current power generation - A Triton 6 platform in operation. The platform is free to follow the tide maximising energy capture - the semi-submersible spar buoys are always clear of the seabed.
The Triton system has turbines mounted on semi-submersible spar buoys, secured to a seabed anchorage by a rigid swing-arm tether. This gives a platform that can be towed to the site already assembled, then deployed into its operating position by simple water ballasting.
By de-ballasting, the system can be brought back to the surface when required – for example for annual maintenance, de-fouling or repair.
All of the electrical equipment required to produce grid-compliant electricity can be contained within the Triton structure and accessed, both in the operating and maintenance positions.
‘Triton’ is a tidal energy platform system being developed by TidalStream Limited. It offers tidal turbine developers a more cost effective deployment and operation system for their turbines than can be provided by single installation systems.
The platform is adaptable and a range of turbine types can be accommodated, providing the installation and maintenance base that will reduce costs and enable safe operating conditions.

The Triton platform
system:
- up to 10MW of turbine capacity from a single seabed installation
- float-out installation and removal
- on-board access for scheduled maintenance and unscheduled repairs, with minimal downtime
- can support a range of turbines from 3rd party developers
- can use gravity base, pinned located or single pile foundation
- catamaran sea-going stability for the roughest conditions
- cost of energy potentially at or below that of offshore wind - and half that of single tidal turbine installations.
Triton - large scale tidal power potential
Triton has been selected by SSE Renewables for inclusion in the BRIMS Scoping Report, August 2013. The Brims Tidal Array site is located to the south of Hoy in Orkney and within the Crown Estate’s Pentland Firth and Orkney Waters Strategic Area. The site will prove a major first step in delivering large scale tidal power to the UK national grid and has a potential maximum capacity of 200MW.
Using 10MW rated Triton platform systems, this requirement could be met by just twenty units - each extracting energy from the full water depth.

TidalStream is undertaking a project through the TSB ‘Marine Energy: Supporting Array Technologies’ programme to confirm the seabed connection methodology of the platform.
