Project "Deep Green"

The Minesto Kite System is lowered to the seabed at a depth of 120 m (400 ft) and can already generate power at low current speeds of around 1.2 ... 2.5 m/s (4 ... 8 ft/s). The kite-shaped device equipped with a turbine is buoyed by the tidal current which moves it in a figure-8 course, helping it reach speeds of comparatively ten times higher than the current. Areas where the Kite System is currently in operation are Holyhead Deep, Great Britain, and Strangford Lough in North Ireland. The current turbines were supplied by Schottel Hydro Germany, and the operator is the Swedish company Minesto. The output of an individual system is at 0.5 MW.

Utilized mechanical seals

EagleBurgmann marine mechanical seal type 19.9700.170.01

Project "Triton"

The Triton platform system enables the installation of any number of current turbines from different manufacturers. The individual turbines are mounted to a supporting structure that is lowered either partially or fully into the ocean and then anchored to the seabed. The platform can be turned to a position that allows easy access for maintenance work. The Fundy Ocean Research Center for Energy is currently testing the Triton T36 in the Bay of Fundy in the Canadian Nova Scotia. The newly developed platform is fitted with 36 Schottel Hydro SIT Instream turbines and supplies an output of 2.5 MW.
