Abstract

This paper reports on wavetank measurements of hydrodynamic loading on a model of offshore structure in waves and current. The model is a large scale steel structure, 3.2 m high, geometrically similar to a real four-legged jacket platform bottom-standing in the ocean floor. Two series of tests were conducted. The model is firstly mounted on a fixed 3-DOF force balance and tested under regular incident waves. On a second stage the force balance is removed to the top of the structure, which is then suspended from the carriage of the tank. The entire experimental apparatus is advanced in still water and i
