Abstract
A slip assembly particularly adapted for use in conjunction with forming a supportive connection between a subsea template or related support structure and support pilings for the template. The slip assembly comprises a floating slip bowl for receiving a plurality of cylindrical slip segments which are movable radially inwardly into gripping engagement with a support column or pile member by a hydraulic cylinder actuator assembly which is connected to a cylindrical ring having a link interconnected with each of the slip segments to permit radial inward and outward movement of the segments in response to axial extension and retraction of the actuator. The slip assembly includes an upwardly facing guide funnel for guiding the pile into a central passage through the slip assembly.
