Riser assist for wellsites
An apparatus and associated method is disclosed for a riser hanging system. The apparatus includes a first elongated member with a provision for a first external mechanical coupling at a distal location on the first elongated member. A second elongated member is mechanically coupled to the first elongated member at proximal locations on the first elongated member and the second elongated member. A third member is mechanically coupled to a first portion of the first elongated member. The third member includes a fourth member to move through at least a second portion of a length of the second elongated member. Mechanical couplers associated with the second elongated member are provided for a second external mechanical coupling of the riser to the apparatus. The riser may be hoisted using the apparatus for better control during coupling to the wellhead.
