US 2026/0176938 A1 · SUBSEA FLUID TRANSFER SYSTEM AND PROCESS FOR USING THE SAME

Abstract

Subsea fluid transfer systems and process for using same. The subsea fluid transfer system can include first and second end termination assemblies, a plurality of fluid transfer conduits, and a plurality of separator assemblies. The first and second end termination assemblies can each include a mechanical connector first part, a fluid coupler first part, and a fluid header conduit in fluid communication with the fluid coupler first part. The plurality of fluid transfer conduits can be in fluid communication with the fluid header conduit of the first and second end termination assemblies. Each separator assembly can define a plurality of conduit bores therethrough and each fluid transfer conduit can be disposed within a corresponding conduit bore defined each separator assembly. The plurality of separator assemblies can be distributed along a length of the plurality of fluid transfer conduits and configured to maintain a separation distance between adjacent fluid transfer conduits.
