Abstract
With gap elements modeling the gap contact condition between jacket platforms guided supports and the conductor pipe, the deflections of the conductor pipe induced by the motions of Jackup in cantilever mode, and offsets of the jacket platforms under operating conditions are investigated. The limiting relative excursions between the jacket out of phase or in phase with the jackup and the distributions of the moment are quantified by the strength and stability analysis of the conductor systems. The results show to avoid an overload for given conductor strength and dimensions, the maximum relative displacement between jackup and jacket platform with guide offsets is about 75.0cm.
