TIDAL ENERGY TECHNOLOGY
PLAT-I (PLATform for Inshore energy) is a innovative floating tidal energy system and the first of its kind in the world. It is dependable, maintainable and accessible year-round, and its modular design allows for it to be easily assembled on-site. The tidal platforms only require 2 meters of water for launching and towing them to their deployment location. The system is moored with a turret configuration allowing it to weather-vane with the tide or river flow. The SCHOTTEL SIT250 turbines are mounted on SIT Deployment Modules (SDMs) allowing them to be quickly raised above the surface for inspection and maintenance, while also reducing draft for transit.
For a complete solution, we design, produce and install innovative rock anchoring and mooring systems such as screw anchor piles, groutless rock anchors, and grouted annular piles.
We value the health of marine environments and so protecting wildlife is essential to our projects. We are committed to the reliable collection of environmental data to provide valuable information regarding the interaction of in-stream tidal energy devices and their surrounding environment.

SWING UP TURBINE DEPLOYMENT MODULES
PLAT-I’s design has been developed through numerical modelling and scale model testing at the University of Edinburgh’s FloWave test tank. Its trimaran design provides low resistance and enhanced lateral and longitudinal stability. The mooring turret integrated into Sustainable Marine's proprietary design enables alignment with the tide or river flow in any direction. The swing up turbine deployment modules (SDMs) allow access to the turbines above the surface of the water, and coupled with the low mass of the SCHOTTEL turbines allows blades and nacelle to be swapped on-site.
