Triton S - Small Platform 1 - 3 MW

Back Button 2

The TS platform can accommodate several rows of turbines, making it adaptable to either a few large turbines or multiple smaller turbines, as well as to different turbine types including fixed or variable pitch and shrouded or non-shrouded. Access can be gained to the electrical rooms at the tops (bows) of the spar buoys in both operating and maintenance positions.

Example - Triton S 1.25 MW:

This layout accommodates 25 SCHOTTEL STG 50 turbines, mounted on three rows.  The small size of the turbines enables low total weight/MW, lower cost and simplified location and handling.

These turbines have markedly lower weight and cost, enabling low overall system cost and simplified location and handling.
