Abstract
Three-column TLP is a new design variation of the common four-column TLP. The objective of this study is to find the hydrodynamic feasibility of the three-column TLP. This accomplished by comparing the three-column design to the ISSC TLP. The ISSC TLP is chosen as the parent TLP and the column diameter, distance between column centers, water depth, environment and pontoon dimensions are kept the same for the ISSC TLP. The initial design shows a satisfactory hydrodynamic characteristic set for the three-column. A detailed coupled analysis of the platform is done using Higher Order Boundary Element Application (HOBEM). The wave excitation forces, responses and average drift forces are computed for wave heading 0 degree and 30 degree. A non-linear quasi-static study is done for the tendons. The three-column design is compared with the four-column design and the comparison shows the two are hydrodynamically similar. Three-column TLP can be considered as a viable alternative for four-column TLP.
