1. A line termination system for a riser string, comprising:
a slip joint having an axis and an outer diameter;
a ring adapter mounted to the slip joint and having an adapter feature formed therein;
a ring body mounted to the ring adapter and having a body feature for engaging the adapter feature on the ring adapter for radial alignment therebetween, and a discontinuity formed in the ring body such that the ring body is circumferentially discontinuous with respect to the slip joint, wherein the discontinuity defines a dimension that exceeds the outer diameter of the slip joint, such that the ring body moves radially with respect to the slip joint such that the slip joint passes through the discontinuity during assembly and disassembly of the riser string; and
a plurality of terminal blocks mounted to the ring body for terminating termination lines associated with the riser, wherein the plurality of terminal blocks are in fluid communication with the termination lines associated with the riser string via the ring adapter string.
