Conduit support assemblies and processes for using same

A process for connecting a conduit to a conduit support assembly disposed on a structure floating in a body of water, comprising:

• filling an interior space of the structure with water, wherein:
• a support apparatus of the conduit support assembly is disposed on a first end of a guide tube that is located within the interior space of the structure and in fluid communication with the body of water,
• the support apparatus comprises a support tube, a load ring attached to the support tube toward a first end thereof, a support shoulder located toward a second end of the support tube and extending from an inner surface thereof, a first seal disposed on the inner surface of the support tube between the load ring and the support shoulder, and a split ring assembly configured in an open position,
• the load ring is moveable relative to the support tube in a direction that is parallel to a longitudinal axis of the support apparatus,
• a hang-off adapter of the conduit support assembly is secured to the conduit,
• the hang-off adapter comprises a first load shoulder disposed on an exterior surface thereof that is configured to matingly engage with the split ring assembly when the split ring assembly is in a closed position, and
• a cover of the conduit support assembly is secured to or against the support apparatus or against a second end of the guide tube to at least partially restrict fluid communication between the interior space of the structure and the body of water;
• removing the cover from the guide tube;
• positioning the hang-off adapter partially within the support apparatus;
• moving the split ring assembly from the open position to the closed position so that the first load shoulder matingly engages with the split ring assembly;
• transferring a load of the conduit to the support apparatus via the split ring assembly and the first load shoulder of the hang-off adapter;
• and
• removing the water from the interior space of the structure.

A process for supporting a load of a conduit from a structure floating in a body of water with a conduit support assembly, comprising:

• filling an interior space of the structure with water, wherein:
• a support apparatus of the conduit support assembly is disposed on a first end of a guide tube that is located within the interior space of the structure and in fluid communication with the body of water,
• the support apparatus comprises a support tube, a load ring attached to the support tube toward a first end thereof, a support shoulder located toward a second end of the support tube and extending from an inner surface thereof, a first seal disposed on the inner surface of the support tube between the load ring and the support shoulder, and a split ring assembly,
• the load ring is moveable relative to the support tube in a direction that is parallel to a longitudinal axis of the support apparatus,
• a hang-off adapter of the conduit support assembly is secured to the conduit, and
• a cover of the conduit support assembly is secured within or against the support apparatus or against a second end of the guide tube to at least partially restrict fluid communication between the interior space of the structure and the body of water;
• removing the cover from the guide tube or the support apparatus;
• positioning the hang-off adapter partially within the support apparatus, wherein the hang-off adaptor comprises a first load shoulder disposed on an exterior surface thereof that is configured to matingly engage with the split ring assembly when the split ring assembly is in a closed position;
• moving the split ring assembly from an open position to the closed position;
• transferring a load of the conduit to the support apparatus via the split ring assembly and the first load shoulder of the hang-off adapter;
• and
• removing the water from the interior space of the structure.
