TRANSIENT SURVIVAL ANALYSIS OF A MOORED FLOATING OFFSHORE PLATFORM: WIND BIASED

In this paper, the very large amplitude roll motions of the capsized MODU OCEAN RANGER is investigated. The dynamical systems approach is utilized to analyze all possible motions for fixed vessel and environmental conditions. The effects of wind bias and an equivalent mooring system is included. As expected, it was found that the effects of wind bias dramatically effected the system's safe basin, a measure of the vessel's resistance to capsizing. Surprisingly, the mooring system was found to have a limited effect on the roll due to it's small size relative to the hydrostatic roll restoring moment.
