Dynamic Behaviour of Tension Leg Platform under Impulsive Loading
Keywords: Dynamic analysis, tension leg platform, offshore structures, impulse, impulsive loading
AbstractIn the literature on dynamics of tension leg platforms (TLPs), the effect offrequently occurring environmental forces, such as those arising due to wave, wind, current, tide, etc. has given the due consideration. However, less probable forces, such as that arising due to collision ofship with iceberg or any huge sea creature, etc., have not been considered in the study. Such small duration impact forces, usually termed as impulsive forces, may take four possible shapes: (i) rectangular, (ii) sinusoidal, (iii) triangular, and (iv) half-triangular. In the present study, response ofTLP has been obtained for all these four shaped impulsive forces. The result ofthe analyses shows that there is a dramatic change in surge, heave, and yaw responses of TLP due to such forces. In addition, a comparative study to find the most influencing impulsive force out of these four has also been conducted.
