Abstract
A light-weight, modular drilling template. A template is constructed of light-weight tubular steel having ring stiffeners to provide adequate crush resistance to withstand collapse under hydraulic loading provided by water pressure at 1800 feet water depth. The template is constructed as a pod-receiving frame with separable pods that may be installed after the frame has been set on the seafloor and leveled. The individual pods may be fine tune leveled by means of adjustable jacking mechanisms that form part of the latching devices that secure the pods to the frame. A method for installing a foundation template subsequent to installing the drilling template is also described.
