SI Ocean Project: Tidal & Wave Energy
Share your data with internal and external clients with the help of MIKE CUSTOMISED! The above example demonstrates on-line access to DHI wave and tidal flow model simulations for energy resource scoping studies - view the interactive map at http://si-ocean.dhigroup.com/map
In 2011, 3.4 MW of wave and tidal energy devices in advanced stages of technology development had been tested across Europe. The International Energy Agency Ocean Energy Systems (OES-IA) vision document, "An International Vision for Ocean Energy”, has forecasted a global wave and tidal deployment potential of 337GW by 2050. Reaching these deployment targets would see long-term benefits including a reduction in carbon emissions, greater security of supply, and economic benefits through job creation and inward investment. If Europe is to maintain a global lead in ocean energy and gain the benefits associated with meeting these targets, an aggressive deployment trajectory will be required. Read more >>>

SuperGen UKCMER Course on Tidal Energy at Queen’s University Belfast
As part of their involvement in the SuperGen UK Centre for Marine Energy Research (UKCMER), formerly SuperGen Marine (www.supergen-marine.org.uk), Queen’s University Belfast held a Doctoral Training Programme course at the Queen’s Marine Laboratory in Portaferry during the week 27th to 31st May 2013. Participants from the various SuperGen partner universities attended the course which covered many aspects of tidal energy production from basic tidal mechanics through measurement of hydrodynamic parameters to performance of tidal energy devices and included a field trip to the SeaGen marine turbine installation in Strangford Narrows.
With support from The Academy by DHI, a full 1-day MIKE by DHI training course was included on 30th May providing instruction in the use of MIKE 21 FMHD to demonstrate the role of modelling in resource assessment and device location studies. This collaborative MIKE by DHI training course was presented by Dr Björn Elsäßer (QUB), with assistance from Steve Flood and Dr Suzie Clarke (DHI-UK).
The Bristol Channel area was used for the MIKE 21 FMHD training course. Participants created their own model mesh and then developed hydrodynamic models into which tidal turbines were added in order to investigate impacts on the overall flow field.
Many thanks to Dr Björn Elsäßer, Queen’s University Belfast, and all the participants.

Large scale Interactive coupled 3D modelling for wave and tidal energy resource and environmental impact using MIKE Software
Scotland has substantial wave and tidal energy resources and is at the forefront of the development of marine renewable technologies and ocean energy exploitation. Wave and tidal energy devices will soon be deployed in arrays, with many sites being developed. It is therefore essential to understand how a number of multi-site developments collectively impact on the physical and biological processes over a wider region. Careful selection of array sites may enable the optimum exploitation of the resource while minimising any environmental impacts to an acceptable level.
The TeraWatt project is a £1m project funded by the Engineering and Physical Sciences Research Council through its Marine Challenge Fund. The project consortium has been established under the auspices of the Marine Alliance for Science and Technology for Scotland (MASTS) with scientists from the Universities of Heriot-Watt, Edinburgh, Highlands and Islands, Strathclyde, Swansea and Aberdeen, and Marine Scotland Science (MSS). The overarching objective of the research is to generate a suite of methodologies that can provide a better understanding of the impact of energy extraction on the resource. Approaches will also be developed that can be employed to assess the physical and ecological consequences of changes to the resource. The project objective will be met by investigating spatial changes in wave climate, physical processes affecting sediments, the shoreline & seabed, and the impacts on organisms living in the seabed, their distribution and the significance of these for other ecological processes.
MIKE by DHI software has been chosen by the TeraWatt Consortium to support their research. Coupled MIKE 3 FMHD and MIKE 21 SW models form the foundations of the adopted MIKE software platform. These core models will be augmented by MIKE 21 BW, MIKE 3 FMMT, MIKE 3 FMST, LITPACK, MIKE 3 FM ECO Lab & ABM Lab, EVA and MIKE Animator in order to consider the specific responsibilities of each partner university.

Met-Ocean Design Conditions in the Pentland Firth
The Pentland Firth in the north of Scotland is one of the most energetic marine sites in Europe, with tidal currents reaching velocities of up to 12 knots (more than 22 km/h). That makes it highly attractive for tidal energy projects. However, the site is also exposed to severe wave conditions, making it a very challenging environment for such activities. Detailed knowledge of the local Met-Ocean conditions is required to ensure the reliability of any planned tidal devices.
The MeyGen tidal stream project plans to build a 398MW tidal turbine array - generating the equivalent electricity to power 400,000 homes - in the Inner Sound of the Pentland Firth. In order to ensure that the foundations and turbine superstructure are not over- or under-designed, MeyGen Ltd. commissioned DHI to provide design criteria, fatigue and operational Met-Ocean data for four locations at the project site.
The study observed severe wave-current interaction occurring in the area. This occurs when tidal currents are sufficiently strong enough to alter the characteristics of the wave climate. In conditions where tidal currents oppose the waves, extremely steep waves are produced. DHI were able to simulate this process and capture waves of similar steepness to the field measurements.
DHI’s results will be used by MeyGen Ltd to further optimise their turbine design and make sure their structures are able to withstand the harshest conditions expected in their design lives. Moreover, turbine installation can be planned to maximise safety and minimise cost and downtime. Deployment of the first units is planned to commence in 2014.
