NOTE: This Checksheet does not constitute a rigorous engineering approach to safety. It merely provides a
draft Checksheet for Permitting with whatever benefits/limitations that apply to that process. It in no-way
confirms that the jack-up is suitable for the location. This is a Draft Checksheet and further
