Model tests to establish a design method for TLP-tether systems

;

Model tests were conducted in regular and random waves with a view to establishing a design method for tension leg platform (TLP)-tether systems. Linearized and nonlinear analytical methods were used, and the calculated values were compared with measured values. The nonlinear method was used in analyzing a TLPtether system under such critical sea conditions as would cause the tethers to snatch - a situation that should be avoided in the design of TLP tethers - and under unstable conditions with all tethers at one corner of the TLP broken off. The results of these investigations are reported in this paper.
