8. A method of supporting a pipe on a vessel, comprising:
coupling a first clamp to a pipe, the pipe comprising a longitudinal axis;
coupling a second clamp to the pipe, the second clamp disposed above the first clamp wherein at least one of the first clamp or the second clamp is movable along a longitudinal axis of the pipe to adjust a distance between the first clamp and the second clamp, and at least one of the first clamp or the second clamp is rotatable relative to the other of the first clamp or the second clamp in at least one plane parallel to the axis;
coupling an overhead structure to the second clamp and the first clamp, the second clamp translatably coupled to the overhead structure and the first clamp rotatably coupled to the overhead structure, wherein:
the second clamp is translatably coupled to the overhead structure through a plurality of actuators; and
the first clamp is rotatably coupled to the overhead structure through a plurality of links and a plurality of spherical bearings; and
coupling a platform to the second clamp below the platform, the first clamp movable with respect to the platform along the longitudinal axis of the pipe.
