Hydrodynamic Analysis of a Small Tension Leg Wellhead Platform in Deep Water:Guidelines for Analysis of the Surface Completion Floater

摘要

The objective of the study was to find suitable hydrodynamic methods to quantifydifferent relevant contributions to the extreme motions and tensions in the tendons and risers in extreme 100-year conditions, and to establish guidelines for conducting hydrodynamic analyses. With model tests on a fixed model of the SCF, standard 3D diffraction/radiation programs have been validated for first order wave forces on the hull and have showed that for the means forces, the viscous effects are important.
