COMPUTERIZED ANALYSIS OF OFFSHORE CONCRETE GRAVITY PLATFORMS

Data on wind, currents and waves are briefly discussed for concrete gravity platforms in the North Sea environment. For fluid loading on these structures, the J.R. Morison equation is initially adopted with a qualifying assumption covering drag and inertial forces. The Keulegan-Carpenter number is considered for the relative magnitude of these forces. A Stokes non-linear fifth order theory is adopted for a better description of the wave crest and incidental wave potential. Two well known diffraction theories are used to evaluate and compare the pressure distribution and resulting forces and moments on these structures. A Computer Program F-WAVE is written in Fortran IV to process results on Condeep Platform placed in water depth up to 330 m.
