| 摘 要： | Spar technology has been applied to the deep-sea oil and gas exploitation for several years.From the first generation of classic spar,the spar platform has developed into the second generation of truss spar and the latest cell spar.Owing to its favorable adaptability to wide range of water depth and benign motion performances,spar has aroused quite a lot of interests from oil companies,universities and research institutes.In the present paper,a new cell-truss spar concept,put forward by the State Key Laboratory of Ocean Engineering(SKLOE)at Shanghai Jiao Tong University,is studied both numerically and experimentally.The numerical simulation was conducted by means of nonlinear time-domain fully coupled analysis,and its results were compared to the experimental data.Whereafter,detailed analysis was carried out to obtain the global performances of the new spar concept.Proposals for the improvement of numerical calculation and experimental technique were tabled meanwhile.
