Impact on upending tools
The design of a monopile upending tool is depending on the integrity of the monopile. A slender monopile demands more connection points from the upending tool to divide the load. At the same time, the weight of the upending tool cannot increase as the crane capacity of offshore installation vessels is easily reached with the heavy structures we see nowadays. We saw the same challenges with the design of a floating monopile tool (also called wet tow plug). Although it’s a floating application, it has the same principles as an upending tool. The challenge here was to add strength and redundancy to the floating monopile tool, but without adding more weight to it.
