The ecoSpray Tidal energy platform

 

Abstract: Floating tidal power generation platforms are developed due to their advantages in positioning turbines in strong surface flows, and their potentially more cost effective installation, operation, and maintenance. Developing a platform and mooring system capable of withstanding large turbine thrust loads and wave loads is needed. Numerical modeling of the system is critical to reliably dimension the components without over engineering and overspending. Validation of numerical models using full scale platform deployment data and accurate wave, current, and wind measurements is required to reduce risks. This process ensures sound engineering assumptions are employed, which leads to optimized structural design and reduced cost. With the goal of reducing risks associated with floating tidal platforms, the ecoSpray tidal energy test platform was deployed in Grand Passage, N.S., Canada in March 2016. The design process, construction, and deployment of the ecoSpray platform, moorings, and anchor blocks provide valuable experience for the industry. The development and validation of the floating platform numerical model in ProteusDS and the boundary element method (BEM) code ShipMo3D is reviewed. The results of the time-domain simulations are compared with data from the deployment.


Title: PLAT-O at FloWave: A validation of ProteusDS at modelling response of a taut-moored tidal platform at tank-testing scale

Date: Wednesday, August 30th

Time: 2- 3:20pm

Stream:  Tidal Device Development & Testing 9

Room: Geography Building, Lecture Theatre

Abstract: The motion and mooring tensions of a scaled-down PLAT-O#2 physical model was measured in axial currents at FloWave, Edinburgh. At high flows, the platform ‘squats’ – arc motion along the upstream lines and about their anchors – to a stable lower depth. The compliance improves load share and survivability in extreme seas. To further investigate the squatting motion, the tested set-up is simulated ‘like-for-like’ in ProteusDS software. The modelled and measured trends, motion and line loads, are comparable. A significant lift force is identified with further work focused on estimating it at sea.


Title: IEA OES Task 10 WEC Modelling Verification and Validation

Date/time/location: To be determined

Abstract: This paper is the first joint reference paper for the OES Task 10 WEC modelling verification and validation group. The group is established under the Ocean Energy Systems (OES) Energy Technology Network program under International Energy Agency (IEA). OES was founded in 2001 and task 10 was proposed by Bob Thresher (NREL) in 2015 and approved by the OES Executive Committee EXCO in 2016. The kick-off workshop took place in September 2016 where the initial base line task was defined. Experience from similar offshore wind validation/verification projects (OC3-OC5 conducted within the International Energy Agency Wind Task 30) [1], [2] showed that a simple test case would help the initial cooperation in order to present results in a comparable way. A heaving sphere was chosen as the first test case. The group of project participants simulated different numerical experiments such as heave decay tests, regular and irregular wave cases. The simulation results submitted by the project participants are presented and discussed within this paper.
