Project description
Jack-up global strength analysis was prepared to demonstrate that after accounting for wasted areas the jack-up hull is structurally adequate to withstand the maximum survival for the environmental criteria noted in the Operating Manual.

FEA Model


Stress Plot

R.E. Scope of work
was to prepare stress analysis of hull structure for survival storm conditions and compare results between as-built plate thicknesses and wasted plate thicknesses (15 % less). The main plating (main deck, bottom deck, side shell, internal BHD, stiffeners and beams) was also checked per applicable ABS minimum scantling requirements.
Engagement Conditions
Upload your problem to us and give us relevant input to allow us to resolve your problem, we will need:

1. As built drawings to create 3D model.
2. Static and environmental loads.
3. Wasted area of structural elements.
