  • Split base plate assembly for multiple completion wellheads
    Patent number: 6857471
    Abstract: A base plate assembly for supporting a number of tubular strings within a tubular housing comprises two base plate portions which when secured together are adapted to be supported on an upper end of the tubular housing. Each base plate portion comprises a top plate which includes an end face and a number of semicircular openings that extend from the end face. Thus, when the base plate portions are secured together, the semicircular openings align to form a number of circular bores which are each adapted to receive a corresponding tubular string. Also, the base plate portions may be disconnected and removed from the tubular housing after the tubular strings are secured in position.
