Multi-Criteria-Decision-Making of Floating Supports with Large-Capacity OWT at Deep Water

Abstract:

The paper presents an assessment methodology for comparable evaluation of a Spar and a Barge support with multi-megawatt OWT. Stability and hydrodynamic performance of both two floaters are checked by SESAM software. Taking consideration of rotational excitation frequencies of the OWT and primary wave excitations, reasonable engineering attributes of the structures are derived. The attributes are applied in multi-criteria decision making method-TOPSIS combining with environmental and economic attributes for benchmarking relatively better solution. The outcome of the study would contribute towards a more informed decision making process for the most suitable configuration of a new floating support structure for large wind turbine at deeper water.
