Subsea well template levelling system
A template levelling system is described for levelling a template on piles implanted in the floor of a body of water. The template has receptacles, comprising in combination: a pile receptacle carried in each template receptacle on a gimbal, the pile receptacle having a lower flange extending outwardly from and below the template receptacle; slip means located within each of the pile receptacles for gripping one of the piles to prevent downward movement of the template with respect to the piles; and hydraulic jack means for gripping the pile receptacle and pulling it and the slip means upwardly, causing the flange to contact the lower side of the template receptacle to lift the template to a level position.
