Apparatus and method for supporting structures on offshore platforms
First Claim
1. An apparatus for supporting an injector head on a platform comprising:
- a base frame mounted to the platform, said base frame having a first bracket and a second bracket attached thereto;
a x-axis frame having a first pivot point and a second pivot point, and wherein said first pivot point is pivotly connected to said first bracket and said second pivot point is pivotly connected to said second bracket so that said x-axis frame is movable along an x axis, and wherein said x-axis frame has a third bracket and a fourth bracket;
a z-axis frame having a third pivot point and a fourth pivot point, and wherein said third pivot point is pivotly connected to said third bracket and said fourth pivot point is pivotly connected to said fourth bracket, and wherein said upper frame is movable along a z-axis;
a sliding frame assembly operatively positioned within said z-axis frame, and wherein said sliding frame assembly has a plurality of rods and wherein the injector head is operatively connected to said rods;
a top plate attached to said z-axis frame so that a cavity is formed, and wherein said sliding frame assembly is contained within said cavity.

Abstract
An apparatus for supporting a structure on a platform. The platform may be a floating platform. The apparatus comprises a base frame, wherein the base frame has a first bracket and a second bracket attached thereto. The apparatus further includes a x-axis frame having a first pivot point and a second pivot point. The apparatus further comprises a z-axis frame having a third pivot point and a fourth pivot point. A sliding frame assembly is operatively positioned within the z-axis frame, and wherein the sliding frame assembly has a plurality of rods for connecting with an injector head. The apparatus may further include a motion restriction system that restricts movement of the x-axis frame and the z-axis frame. The sliding frame assembly comprises a sliding pad for lateral movement. A method for compensating for the movement of a floating platform having a riser extending therefrom is also disclosed.
