Patent ID: 8905156

Claim:
A template for use in forming a wellbore in a seafloor comprising: a frame; an annular wellbore alignment funnel coupled with the frame; an annular piling funnel substantially coplanar with the wellbore alignment funnel; a coupling defined by an overlap between an elongated tang member coupled to the frame and a clevis member coupled to the piling funnel, and that has a recess adapted to receive the tang member therein, a bore in the overlap, and a main stud, so that when the main stud is selectively engaged in the bore, the piling funnel is coupled to the frame, and when the main stud is removed from the bore, the piling funnel is decoupled from the frame, and sidewalls on the clevis at lateral ends of the recess that extend along elongate sides of the tang member, vertical slots in the sidewalls, and alignment members that extend laterally from elongate sides of the tang and project through the slots when the tang member is in the recess.
