 The Cameron RST Ring is a swivel/tension ring that eliminates the need to manually connect riser tensioner lines and goosenecks every time the riser is run. In the stored position, the RST ring is suspended from the diverter housing. The tension lines, as well as the choke/kill/auxiliary line hoses remain connected to the ring in the stored position. The RST ring is designed to meet customer required tension capacities up to two million Pounds. Features: - Hydraulically actuates the load segments, retracts the alignment pins, stabs the choke/kill/auxiliary line subs and actuates the diverter storage segments.
- Alignment pins ensure proper orientation of the telescoping joint to the RST ring and support the weight of the ring until the load is transferred to the tension lines.
- Load shoulders in the ring are hydraulically extended/retracted to engage/disengage the load shoulder on the telescoping joint.
- Load shoulder position indicators provide visual assurance that the load shoulders are in position.
- Choke/kill/auxiliary line pins are hydraulically stabbed into floating seal subs on the telescoping joint to ensure proper engagement, eliminating the need to manually connect the lines in the moon pool area. Replaceable seal inserts and replaceable pistons on the gooseneck stabs are provided to ensure ease of maintenance.
- Alignment funnel to provide guidance when pulling the riser.
- Full 49-1/2" bore through the ring while running riser.
