Abstract
A system for levelling a template adjacent the floor of a body of water comprising a plurality of gripping assemblies pivotally coupled to the template and receiving the supporting piles therein, with portions of the piles extending above the template; and a jacking assembly capable of being lowered down each of the piles, releasably connected to the template adjacent the associated gripping assembly and raising or lowering the template in the area of each pile to level the template. The jacking assembly comprises an outer housing, and a double acting hydraulic piston slidably received in the housing, with a pile gripping assembly being coupled to the piston. The gripping assembly in the jacking assembly and those in the template are each formed from a plurality of ring segments that are serrated on the inside and have tapered ribs on the outside, these segments being received in a bowl having corresponding tapered ribs. The segments are spring biased upwardly and inwardly into the pile gripping position and released downwardly and outwardly by hydraulically actuated pistons. The method of installing the template comprises landing the template on the floor of the body of water, passing a set of casing piles through passageways in the template and implanting the casing piles in the floor of the body of water with portions of the piles extending above the template, levelling the template, and rigidly connecting the levelled template to the piles.
