A comprehensive motion and load model for tension leg platforms.



Executive Summary

TLPsim is a comprehensive analysis tool used for design, evaluation, maintenance and failure analysis of Tension Leg Platform (TLP) systems. It provides detailed tendon and platform performance data under specifiable water depth and environmental conditions, including characteristic (r.m.s.) and peak tendon loads in the forecast maximum storm. A wide range of environmental conditions is accommodated, including extensive built-in wave spectral types, azimuthal spreading of wave directions, an optional independent background swell, and steady or fluctuating wind and/or current. The program is especially useful for deep-water applications which are difficult to study thoroughly using conventional model-scale tests. Execution is carried out in the frequency domain, resulting in short run times and unambiguous predictions of statistical response values.
