Responses of Square Tension Leg Platform Subjected To Regular Wave

This report provides the analysis of square tension leg platfonn (TLP) subjected to
regular wave. Recent depletion of near shore oil resources is quite a big issue and
therefore, this project studies on other alternatives to extract oil in deep water for
water depth greater than 300m. The assumption made for this project is that the
tension leg platfonn is subjected to a regular wave. Dynamic analysis conducted in
the 'Frequency Domain Analysis'. The project objectives are to detennine the forces
reacted on square tension leg platfonn, to see the responses of square tension leg
platfonn in the direction of surge, heave and pitch, to calculate the tension forces
produced on each tether and to prove that tension leg platfonn is worth in deepwater
exploration. Wave kinematics value is found by using Airy Wave theory while the
acted forces by using Morrison equation. Overall, the responses of the TLP have been
found within allowable limits, thereby confinning the suitability of TLP for
deepwater application.
