Abstract
Abstract Clean energy captured by offshore wind turbines have been widely used for supporting onshore activities. In the near future, facilities such as offshore wind turbines can also play an important role in energy transition of offshore activities. Offshore wind energy can be employed for electrifying the operations in offshore fish farms, which are traditionally supplied by diesel-engine barges/generators. Based on this motivation, this study focuses on a design of shared mooring system between a semi-submersible offshore fish cage and a spar-type floating wind turbine. A numerical model of the proposed shared-mooring system is implemented in a global response analysis software SIMA for performing fully coupled time domain simulations. The configuration of the shared mooring line is determined using an engineering approach which comprises Irvine's formulation, system eigenvalue analysis and cost estimation. Moreover, relevant case studies by altering the environmental conditions are performed. Extreme operational conditions that may give large relative motions are investigated thoroughly. The dynamic performance of the integrated system is compared with that of individual structures. The global motion of the floating wind turbine and its mooring line's tension behavior are obviously influenced by the existence of the shared line. In general, the present work investigates the feasibility of a shared-mooring system for these types of offshore structures and further gives insights about the engineering design procedure.
期刊介绍:
The Journal of Offshore Mechanics and Arctic Engineering is an international resource for original peer-reviewed research that advances the state of knowledge on all aspects of analysis, design, and technology development in ocean, offshore, arctic, and related fields. Its main goals are to provide a forum for timely and in-depth exchanges of scientific and technical information among researchers and engineers. It emphasizes fundamental research and development studies as well as review articles that offer either retrospective perspectives on well-established topics or exposures to innovative or novel developments. Case histories are not encouraged. The journal also documents significant developments in related fields and major accomplishments of renowned scientists by programming themed issues to record such events.
