If you work in the offshore sector, you know that compensating for the vertical heave motion of a vessel is not a new thing when it comes to crane technology.  While lowering equipment thousands of feet down to the seafloor, heave motion is really the only motion that is a significant factor.

For vessels involved with maintaining offshore windfarms however, it’s a completely different story.  While the loads are significantly less than what’s found in deepwater operations, the vessel motions in all three axis make the crane operator’s job much more challenging

Designed especially for the 74 meter Siem Moxie, an infield supply vessel (ISV) that was delivered from Fjellstrand shipyard in Norway last April, this new crane is outfitted with hydraulic systems that enables it to compensate for vessel motions while operating in significant wave heights of up to 3 meters.
