Systems for transferring fluid across a boundary and processes for using same

A system for transferring a fluid between a first body rotatively coupled to a second body, comprising:

• a first fluid conduit disposed on the first body and comprising a first valve;
• a second fluid conduit in fluid communication with the first fluid conduit and comprising a second valve;
• a third fluid conduit disposed on the second body and comprising a third valve;
• a fourth fluid conduit in fluid communication with the third fluid conduit and comprising a fourth valve;
• a first fluid swivel comprising a fixed part rotatively coupled to a rotating part, wherein the rotating part of the first fluid swivel is in fluid communication with the first fluid conduit;
• a second fluid swivel comprising a fixed part rotatively coupled to a rotating part, wherein the fixed part of the second fluid swivel is in fluid communication with third fluid conduit;
• and
• a fifth fluid conduit configured to fluidly connect to either one of:
• (i) the fixed part of the first fluid swivel and the fourth fluid conduit or (ii) the rotating part of the second fluid swivel and the second fluid conduit, wherein:
• the first fluid conduit, the first valve, the first fluid swivel, the fifth fluid conduit, and the fourth fluid conduit define a first fluid path when the fifth fluid conduit is fluidly connected to the fixed part of the first fluid swivel and the fourth fluid conduit, and
• the second fluid conduit, the second valve, the fifth fluid conduit, the second fluid swivel, and the third fluid conduit define a second fluid path when the fifth fluid conduit is fluidly connected to the rotating part of the second fluid swivel and the second fluid conduit.

A process for redirecting a fluid flow from a first fluid path to a second fluid path in a system configured to transfer a fluid between a first body rotatively coupled to a second body, comprising:

• closing a first valve and a fourth valve of the system, wherein the system comprises:
• a first fluid conduit disposed on the first body and comprising the first valve,
• a second fluid conduit in fluid communication with the first fluid conduit and comprising a second valve,
• a third fluid conduit disposed on the second body and comprising a third valve,
• a fourth fluid conduit in fluid communication with the third fluid conduit and comprising the fourth valve,
• a first fluid swivel comprising a fixed part rotatively coupled to a rotating part, wherein the rotating part of the first fluid swivel is in fluid communication with the first fluid conduit,
• a second fluid swivel comprising a fixed part rotatively coupled to a rotating part, wherein the fixed part of the second fluid swivel is in fluid communication with third fluid conduit;
• and
• a fifth fluid conduit fluidly connected to the fixed part of the first fluid swivel and the fourth fluid conduit, wherein the first fluid path is defined by the first fluid conduit, the first valve, the first fluid swivel, the fifth fluid conduit, the fourth fluid conduit, and the fourth valve;
• disconnecting the fifth fluid conduit from the fixed part of the first fluid swivel and the fourth fluid conduit;
• connecting the fifth fluid conduit or a sixth fluid conduit to the second fluid conduit and the rotating part of the second fluid swivel;
• and
• opening the second valve and the third valve to establish fluid communication between the second fluid conduit and the third fluid conduit, wherein the second fluid path is defined by the second fluid conduit, the second valve, the fifth fluid conduit or the sixth fluid conduit, the second fluid swivel, the third valve, and the third fluid conduit.
