Abstract:
1. An umbilical system for providing utilities to a rig by suspending conduit above at least one rail, the umbilical system comprising: a first cart capable of elevating a first portion of conduit a maximum clearance distance from a level of the at least one rail, the first cart comprising: a) a first base; b) at least two first cart right-side wheels for slidably engaging a first rail among the at least one rail, each wheel having an axle; c) at least two first cart left-side wheels for slidably engaging a second rail among the at least one rail, each wheel having an axle; and d) a pair of substantially vertical supports attached to the first base, the pair of substantially vertical supports, joined together at a distal top end, the pair of substantially vertical supports supporting a first arched conduit-support surface entirely above the at least one rail, wherein the first arched conduit-support surface exposes a convex surface upwards and having lips that droop downward; a second cart capable of elevating a second portion of conduit the maximum clearance distance from the level of the at least one rail, the second cart comprising: a) a second base; b) at least two right-side wheels for slidably engaging the first rail among the at least one rail, each wheel having an axle; c) at least two left-side wheels for slidably engaging the second rail among the at least one rail, each wheel having an axle; and d) a pair of substantially vertical supports attached to the second base, the pair of substantially vertical supports, joined together at a distal top end, the pair of substantially vertical supports supporting a second arched conduit-support surface, wherein the second arched conduit-support surface exposes a convex surface upwards and having lips that droop downward; wherein the second rail is substantially parallel the first rail.
