Installation followed the turbine unveiling ceremony held in Invergordon on 12 August. After the event, Atlantis, in conjunction with Hallin Marine, loaded the 22.5m tall, 1300 tonne structure on to the DOF vessel, the Skandi Skolten, to be taken to its dedicated berth at the EMEC.

Once there, it took only seven days to install the gravity base structure, over 1000 tonnes of ballast blocks, and finally the turbine nacelle with its pair of 18m diameter rotors.

The power converter in this 1300 tonne machine is thought to be the largest and most powerful tidal power turbine ever built. Its unveiling was described by Atlantis as a major milestone for the company as well as for the development of the UK’s marine power industry as a whole. “Today is not just about our technology, it is about the emergence of tidal power as a viable asset class that will require the development of local supply chains employing local people to deliver sustainable energy to the local grid,” said Atlantis CEO Timothy Cornelius. “The AK1000 takes the industry one step closer to commercial scale tidal power projects.”

The turbine is rated at 1MW at a tidal velocity of 2.65m/sec. It is the result of ten years of research and development by Singapore-based Atlantis which began scaled testing of tidal prototype designs in 2002.

Since 2002, Atlantis has built, tested and grid-connected a 100 kW tidal device known as the Aquanator, and a 150 kW device called Nereus. In 2008 it unveiled its Solon (AS) series to the market.
