Abstract

A frequency-domain procedure for the extreme surge response prediction of tension leg platforms (TLP) under waves and current loading is presented and evaluated. The procedure incorporates both first- and second-order viscous and potential (inviscid) effects. The evaluation is based on results of hydrodynamic tests performed on a 1/60 scale model of a TLP. The tests were specifically designed to quantify the wave current interaction effects on surge. Therefore, the TLP model was tested under currents only (simulated by towing), waves only, and combined waves and current. The procedure is shown to perform well for predicting the extreme response in random waves and current except when groups of large waves are present. In this case, the extreme response is underpredicted. Areas in which this situation can be improved are identified.

Time-domain model for TLP surge response in extreme sea states

Conference Finnigan, T; Botelho, D; Petrauskas, C - Proc., Annu. Offshore Technol. Conf.; (United States)

A time-domain model is presented and evaluated for the prediction of the surge response of a tension leg platform (TLP) in regular and random waves, in the presence of a current. The wave force equation in the model is a modification of the Morison equation. Wave diffraction effects are incorporated in an approximate manner. The time-domain model is evaluated on the basis of experimental tests that were performed on a 1:60 scale model of a TLP. The tests were specially designed to investigate the effect of combined waves and current on surge response. The tests were conducted in regular, randommore »« less
Analysis of non-Gaussian surge response of tension leg platforms under wind loads

Journal Article Kareem, A; Zhao, J - Journal of Offshore Mechanics and Arctic Engineering; (United States)

The nonlinearity in the wind loading expression for a complaint offshore structure, e.g., a tension leg platform (TLP), results in response statistics that deviate from the Gaussian distribution. This paper focuses on the statistical analysis of the response of these structures to random wind loads. The analysis presented here involves a nonlinear system with memory. As an improvement over the commonly used linearization approach, an equivalent statistical quadratization method is presented. The higher-order response cumulants are based on Volterra series. A direct integration scheme and Kac-Siegert technique is utilized to evaluate the response cumulants. Based on the first four cumulants,more »« less

A computer aided design approach for deep water tension leg platforms

Conference Johnson, C

In this research, a software package was developed under the sponsorship of the Offshore Technology Research Center that is funded by the National Science Foundation and administered by The University of Texas at Austin and Texas A and M University. This software package (Johnson (1993)) was especially conceived for educational or research purposes with emphasis on user interfaces, automatic data generation and graphical display. As a result, a state-of-the-art workstation approach was developed that incorporates sound analysis procedures for deep water Tension Leg Platforms (TLPs). The TLP program (OTRC-TLP-2D93) is easy to use -- yet it is capable of producingmore »« less
Direct wave force measurements on a model tension leg platform

Journal Article Vandiver, J - Ocean Sci. Eng.; (United States)

A 1:50 scale model of a tension leg platform without tethers was rigidly attached to a five degree of freedom load cell frame. Regular waves with prototype periods of 4.7 to 14.1 seconds were passed through the model. For each wave frequency wave amplitude to wave force transfer functions were measured as a function of incidence angle. Wave incidence angles were varied in five degree increments. Force transfer functions for the five rigid body degrees of freedom in heave, pitch, roll, surge, and sway were measured and compared with numerical predictions. By applying the principle of reciprocity for linear wavemore »« less
Combined system analysis of tension leg platforms: A parallel computation scheme

Conference Song, X; Kareem, A

This paper concerns dynamics of a tension leg platform (TLP) under wind, wave, and current load effects. A parallel computation scheme for coupled analysis of TLP-tether system is utilized. The method encompasses the combined response of TLPs through coupled substructural systems involving the top platform and bottom tethers. The coupled platform-tether analysis of the example TLP suggests that the nonlinear effects introduced by the tether curvature, mass and varying tension are important, and these effects become more pronounced as the water depth increases. Use of conventional approach that involves several simplifications to evaluate the influence of tethers on the overallmore »« less
