Abstract
A motion compensating system and method for use on a vessel during well intervention operations through a riser. The system can comprise an upper floor having an opening therethrough, a lower base having an opening therethrough positioned below the upper floor, a first plurality of cylinders extending between the upper floor and lower base, and a riser tensioner. Each cylinder of the plurality of cylinders can be pivotally connected to the upper floor and lower base for moving the upper floor with respect to the lower base. The riser tensioner can have an upper portion, lower portion, and central cavity extending longitudinally through the upper and lower portions, wherein the upper portion can be adapted for connection with a riser or an intermediate tubular member that is connectable to the riser. The lower portion can be connected to the lower base within or about the opening of the lower base.
