Abstract

Model tests carried out at 1/14.5 scale on two production risers in a towing tank are described. One of the risers considered is modeled on that used in the Buchan field, while the other has a compact low drag configuration of the same production capacity. The tensioning system was carefully modeled, and vessel surge motions were accurately represented in both regular and irregular waves. Current was represented by carriage motion. Some results are presented for bending moments and displacements for both models and comparisons are made with computer simulations to deduce appropriate values for hydrodynamic coefficients.
