56 02 MARKET AND INDUSTRY TRENDS energy project in the Mokpo Jeonnam region of South Korea, and another one in the United Kingdom, off the Isle of Man.20 In spite of the challenges faced, in early 2015 Aquamarine reported operating data for its Oyster 800 device, noting that it has operated as expected and even exceeded expectations at high sea statesi . The company’s plan is to continue development of the next generation of the device along with the WavePOD, a subsea generating unit for wave energy generators that is being developed in co-operation with several other parties.21 Atlantis Resources (UK/Singapore) announced in early 2014 that it had reached an agreement with Dongfang Electrical Machinery (China) for testing in preparation for deployment of Atlantis’s 1 MW AR1000 tidal stream turbine at an offshore demonstration project in Zhejiang Province in China. Dongfang also would provide low-cost manufacturing for the new 1.5 MW AR1500 turbine, which was developed by Atlantis in co- operation with Lockheed Martin (United States). 22 Having acquired a majority stake in the MeyGen project in Scotland in 2013, Atlantis Resources announced in early 2015 that it had commenced construction of onshore facilities, including directional drilling for subsea cables for turbine interconnection.23 Atlantis also announced a construction contract with Lockheed Martin to build Atlantis’s AR1500 turbines for the project, scheduled for delivery in 2016. The turbines feature active rotor pitch control and full nacelle yawing capability.24 In addition, Atlantis signed a contract with Andritz Hydro Hammerfest (Norway) to supply three 1.5 MW tidal turbines to the first phase of the MeyGen Project.25 OpenHydro (a subsidiary of DCNS, France, since 2013) partnered with Alderney Renewable Energy in plans to develop a 300 MW tidal array. The joint venture, called Race Tidal Ltd., would use 150 of the company’s 2 MW turbines.26 Following tests in Brittany (France), OpenHydro and EDF (France) committed to deploying two new turbines as a pilot project in 2015, with an eye towards pre-commercial farms in subsequent years.27 Alstom (France) also has plans in the area. In late 2014, together with GDF Suez (France), Alstom was chosen by the French government to supply four of its new turbines for the Raz Blanchard (Alderney Race) tidal pilot project, to begin operation in 2017, with an expected operational lifespan of 20 years.28 The company will deploy its improved tidal turbine technology, the 1.4 MW Oceade 18, featuring variable pitch blades and rotating nacelle to best face the oncoming tide.29 Nautricity (Scotland) tested its 500 kW dual-rotor contra- rotating marine turbine (CoRMaT) during 2014 at EMEC’s test bed in Shapinsay Sound (Scotland). In early 2015, the company secured an alternate grid-connected testing berth at EMEC’s Fall of Warness site, where stronger tides allow further testing under the harshest sea conditions.30 Magallanes Renovables (Spain), supported by the EU-funded Marinet project, launched a prototype of its floating ATIR turbine at EMEC in late 2014 for its first testing at sea. A full-scale version would have a capacity of 2 MW.31 OpenHydro also continued to test and develop its technology at EMEC, installing a new generation of its device in early 2014.32 New tidal projects were planned at Canada’s Fundy Ocean Research Center for Energy (FORCE) in the Bay of Fundy. OpenHydro and its local partner Emera were given a green light at FORCE for their plan to deploy two 2 MW tidal turbines in 2015 as a first phase towards a commercial-scale project known as Cape Sharp Tidal.33 Black Rock Tidal Power (Canada), a subsidiary of marine propulsion manufacturer Schottel (Germany), was offered a demonstration berth to deploy its technology, which combines a Triton platform developed by TidalStream (UK) with 16 of Schottel’s 70 kW “floating” tidal generators (STG).34 Schottel also saw its STG turbines deployed at another test site by Sustainable Marine Energy (UK) off the Isle of Wight.35 Later in 2014, the newly formed Schottel Hydro announced its new instream turbine (SIT). The company’s technology is based on the premise that reducing turbine size leads to a better ratio of power and material use.36 The ocean power industry saw some acquisitions in 2014, in addition to Wave Energy Scotland’s purchase of Pelamis’ assets. Fortum (Finland) acquired a minority stake in Finnish wave energy developer Wello.37 Wello’s single device, called the Penguin, is said to contain all original parts from the time of construction in 2011, establishing confidence in the durability of its design.38 The Penguin is a floating platform that encapsulates a rotating eccentric mass that is actuated by waves, driving a generator typically used in wind turbines.39 Tocardo acquired fellow Dutch company IHC Tidal Energy from Royal IHC. In doing so, Tocardo supplemented its horizontal-axis turbines with a vertical-axis technology that is nearing commercialisation.40 In early 2015, Tocardo also acquired the intellectual property of Swanturbines (UK), including its subsea tidal turbine technology.41 In recent years, tidal and wave technologies have advanced the most of all ocean energy technologies, with tidal power expected to be commercially viable earlier than wave technologies.42 While tidal technologies show a greater convergence in design, wave energy devices are more varied and generally have not reached the same stage of development. The differentiation in wave energy devices is due in part to variability in wave resource characteristics at different water depths.43 i - A sea state is a general condition of the ocean surface with respect to waves and swell as generated by tidal forces and wind.
