As part of the development of the tidal resources of Alderney, ARE commissioned Osiris Projects ( to undertake a series of combined hydrographic, geophysical and oceanographic surveys within the Alderney Race area.

In addition, Osiris Projects completed an investigation into two potential interconnector routes; one 29km route between Alderney and France, and another 36km route from Alderney to Guernsey.
