Abstract

Research teams from the Departments of Mechanical Engineering at Heriot-Watt University and University College London began a program of model basin testing in 1980 to supplement the scarce data available for verification of marine riser simulation computer programs. Combinations of floating platform and riser models were subjected to regular and random wave excitation and the resultant displacements and bending moments of the riser were recorded as digital time histories on computer discs. Three riser configurations were chosen for study: Two were of circular cross-section but of different diameter to length ratios, while the third model was of a multi flow line pattern. The test facilities, techniques, scaling effects and results are discussed.
