Abstract
Systems and methods for stabilizing a riser or similar object against motion can include engaging two or more cylinder apparatus to the object. Communication of fluid between cylinder apparatus, responsive to a force on the object, can limit movement of the object, such as through extension or retraction of pistons within the cylinders. The cylinder apparatus can include internal channels that can accommodate coiled tubing, slickline, wireline, and similar conduits or devices, enabling operations to be performed through the cylinders, independent of their position.
