1. A system for facilitating multiple interventions in a plurality of wells, comprising:
- a jacking frame mounted on an offshore fixed platform associated with the plurality of wells;
a vertical adjustment mechanism coupled to the jacking frame for vertically adjusting at least a portion of the jacking frame to vertically position well equipment above the wells for an intervention operation in the wells;
a pair of opposing jib cranes mounted to the jacking frame; and
a translation system comprising rails modularly coupled to the offshore platform and to the jacking frame to move the jacking frame laterally along the offshore fixed platform to facilitate access to the plurality of wells, the rails adaptively coupled to the platform in a configuration to enable multiple interventions in the plurality of wells.

Abstract
A technique facilitates intervention operations in a plurality of wells from an offshore fixed platform. A jacking frame is movably mounted on the offshore fixed platform to provide access to selected wells of the plurality of wells. The jacking frame is coupled to a translation system that enables horizontal movement of the jacking frame along the offshore fixed platform to better position the jacking frame for intervention in desired wells. One or more jib cranes are mounted to the jacking frame to lift or deploy equipment with respect to selected wells.

10. A method of treating a plurality of wells, comprising:
-
assembling a plurality of modular rails to form a translation system on an offshore platform associated with the plurality of wells, the rails adaptively assembled according to a configuration of the platform and the plurality of wells; mounting a jacking frame to the translation system for movement along the platform; moving the jacking frame horizontally along the platform to provide access to specific wells of a plurality of wells by moving the jacking frame in a first horizontal direction with a winch and by moving the jacking frame in a second horizontal direction with a hydraulic system; adjusting at least a portion of the jacking frame in a vertical direction to position equipment vertically with respect to the wells; and delivering the equipment into or out of selected wells with a jib crane mounted to the jacking frame for movement with the jacking frame. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system, comprising:
-
a jacking frame mounted on an offshore fixed platform associated with a plurality of wells, the jacking frame comprising at least one mounting platform; a translation system coupled to the jacking frame to selectively move the jacking frame horizontally toward selected wells; an injector rotatably mounted on the mounting platform to inject coiled tubing into and out of the wells; a height adjustment mechanism to enable selective adjustment of the height of the injector with respect to the wells; and a jib crane mounted on the jacking frame to deliver equipment to selected wells. - View Dependent Claims (18, 19, 20, 21)
