Abstract

A method of placing a template on the seafloor beneath a floating vessel. The method comprises suspending the template beneath at least one sling-mounted pendant buoy and using a tow cable and restraint cable to position the template in a position generally centered beneath the vessel. An extendable support, such as a drill string, may be connected to a previously attached descent sling, control lines and buoy slings detached, additional ballast added as needed, and the template lowered to the seafloor.
