Design Optimization of Ocean Wind Turbines
Arnfinn Nergaard, UiS, arnfinn.nergaard@uis.no
Objective
The Ocean Wind Turbine (OWT) industry is at its very early infancy. There are a few cases however, all based on taking “land” turbines offshore. Taking a land turbine into deep waters, we basically need tree new systems; a floater, a station keeping system, and a subsea power transmission system. The three key elements in this proposal are the turbine, the floater and the station keeping system. While the present first generation OWTs are designed with floater and station keeping systems to suit existing land turbine technology, it is more than likely that future designs will be based on an integrated system design approach where the turbine, the floater and the station keeping system are designed with a strong interrelation between all disciplines for optimizing the design. The key parameter to optimize is the ultimate energy cost in terms of NOK/kWh, must take both investment and operational cost into consideration.
Proposed Steps in the Project
• Establish a design basis for a case application. This will consist of the nature given conditions, any applicable R&R and operational requirement in terms of capacities and regularity.
• Scrutinize important merits and establish requirements for a new OWT rotor/turbine. Screen existing rotor system designs and analyse match with wanted merits. This will have to be done in cooperation with a recognized wind power engineering institution. This might lead to proposals for new designs altogether. The main outcome of this activity ought to be weights, forces, dynamic loads, COG, and mechanical interface requirements between the rotor/tower and the floater.
• Scrutinize important merits and establish requirements for a new OWT floater. Screen existing floater alternatives and analyse match with wanted merits. This might lead to proposals for new designs altogether. The main outcome of this activity ought to be layout GA designs of the proposed floater(s) with key parameters like overall dimensions, COG, and ballasting requirements etc.
• Scrutinize important merits and establish requirements for a new OWT station keeping system. Screen existing alternatives and analyse match with wanted merits. This might lead to proposals for new designs altogether. The main outcome of this activity ought to be station keeping system designs with specifications, operational merits, operational characteristics etc, and impact on multi turbine wind park layout.
• Global and structural motion analysis of the complete and combined unit to determine the motions themselves and consequences for global and structural forces in all the three elements.
It is proposed to see this as an iterative process with a number of loops until technical improvement potential is judged to be relatively small.
Proposed Final Step
Establish a simple economy model and estimate investment and operational cost for the new OWT to indicate its overall energy cost levels and finally to compare with competing concepts.
Deliveries 2010
• Establishment of a preliminary design basis for the overall project.
• Establish contacts with other institutions and potential industry partners
