Cable company Nexans has been awarded a contract by StatoilHydro ASA to supply the submarine cables for the Sheringham Shoal Offshore Wind Farm project, located around 20 kilometer (km) offshore from Sheringham, on England's north Norfolk coast. The contract scope includes engineering, procurement and construction of two 22km, 145 kilovolt (kV) XLPE submarine export cables, and a spare cable with associated equipment. An optical fiber cable will also be included.

Proving once again that there is little new under the sun (or the waves) is this 1932 version of the wave power generators that we showed here and here. It works on the basis of an "inertia motor" where "When a wave starts to lift the hollow sphere, the massive weight inside, because of its inertia, resists the movement and exerts terrific pressure in the lower cylinder. Finally the inertia of the weight is overcome. Then it possesses momentum. When the sphere reaches the crest of a wave, the combined effort of the momentum and the recoil of the huge, semi-elliptic springs exerts an equal pressure in the upper cylinder. The tremendous pressure is applied to oil, which, in turn, operates a special turbine which runs a generator. The current is conducted to the shore by submarine cable."

The Dutch and Danish power grid operators have announced they are to carry out a feasibility study into the possibility of an underwater electricity cable between the two countries, reports ANP news service. The two firms say the so-called Cobra cable will facilitate the use of renewable power. 'Strong connections between European countries can significantly increase how much wind power can be distributed on European grids,' Peter Jorgensen, one of the directors of Enereginet is quoted as saying. On Thursday the NorNed cable between the Netherlands and Norway – at 580 kms the longest underwater power cable in the world – was officially opened by the Dutch economic affairs minister Mara van der Hoeven. The cable has been operational since May.
