Weight is an important design factor and a primary feature in determining the physical characteristics of a rig. In the marine construction industry, lightship displacements are widely reported, but in jackup construction, designers protect information on the weight of the vessel because weights are an indicator of the design and strength of a rig’s legs which is an important distinguishing feature among designs. Methods for predicting ship weight based on physical attributes have been used for decades, but given the structural differences between jackups and ships, these techniques do not adequately predict rig weight. In this chapter we present an empirically derived lightship displacement function useful for first-order estimates.
