TidalStream Technology

The TidalStream Triton dual-mode platform enables highly cost effective deployment and operation for a number of horizontal axis tidal turbines.  The turbines themselves use technology and components developed from the wind industry that already exist, and have benefited from ongoing development over the last 20 years. A number of alternative turbines can be used, the SST platform providing the installation and maintenance base that will reduce costs and provide safe operating conditions.

Benefits:

The Triton platform improves the cost effectiveness of single tidal turbines by:

• creating a multi-MW system with a single seabed shear foundation - up to 10MW
• enabling float-out installation without barges, cranes, jack-ups or divers
• providing a stable platform for safe and simple topside access to machinery and systems
• maximising energy capture by using the full depth of the tidal stream (currents near the surface generally run significantly faster than those near the seabed)
• maximising energy and reducing loads by allowing the turbines to align with the flow
   

Seabed Anchorage:

The connection to the seabed is vital to withstand several hundred tonnes of sideways thrust from the turbines.

Unlike other tidal turbine anchorages, there are no large overturning moments, just shear, so that a number of alternative methods are possible, depending on the seabed conditions, depth, currents and accessibility to possible drilling plant.

Some of the options are illustrated below:

The TidalStream technology is scalable - from a twin rotor system up to 2MW system for constrained sites up to the six-rotor 10 MW platform for deeper water and highly energetic sites.

The most powerful tidal current energy generator now in development - 10MW from a single installation

TidalStream have now completed successful testing of a six-rotor scale prototype of Triton demonstrating its versatility, stability, and opportunities for easy access and maintenance
