Abstract
A system for transferring fluids from a free-standing riser to a surface vessel comprises a first valve assembly including a first valve spool and a first isolation valve configured to control the flow of fluids through the first valve spool. In addition, the system comprises a second valve assembly releasably coupled to the first valve assembly with a hydraulically actuated connector. The second valve assembly includes a second valve spool and a second isolation valve configured to control the flow of fluids through the second valve spool. Further, the system comprises a deployment/retrieval rigging coupled to the first valve assembly and configured to suspend the first valve assembly and the second valve assembly from the surface vessel. Each isolation valve has an open position allowing fluid flow therethrough and a closed position restricting fluid flow therethrough, and each isolation valve is biased to the closed position.
