Abstract
A riser tensioner system for offsetting heave and yaw between the riser and the rig on offshore drilling and production platforms during drilling and production operations. A plurality of hydraulic cylinders are connected by a spider. The spider allows individual cylinders to be disconnected from the riser, suspended in place with equipment integral to the riser system, without cranes, and can be repaired without loosening bolts or screws and without wrenches or torque wrenches. Maintenance can take place on one cylinder without disturbing other cylinders supporting the riser. The cylinders can be oriented in a vertical arranged or slanted in an upper end in an inverted cone or 'A' frame orientation.
