A Study on the Motion Characteristics for Habitability of Floating Offshore Structures in the Sea near Korea |
Abstract |
A statictical apporach is emploued to investigate the motion characteristics of the different types of floating offshore structures. A long term cumulative probability is evaluated that the acceleration response of the structure exceeds a limited value. Three type of structures, i. e. a barge,semisubmersible and tension-leg platform are selected as typical floating structures. These structures are assumed to be constructed in-shore Pohang, Pusan, Kusan and Cheju. Theresults of long term prodiction of acceleration responses are compared with the criteria for human exposure to the vibration proposed by ISO, from which the habitability of the different types of floating structures are discused. It is comfirmed that the semisubmersible and the tension-leg flatform are most preferable form the point of view of habitability because the cumulative probability that the response of these structural types exceeds the habitability criteria is much smaller than that of the barge. |
