Abstract: Disclosed is a subsea live hydrocarbon fluid retrieval system and method. The system and method include the ability to depressurize the fluid while enacting controlled venting of the gas entrained in the fluid during a controlled ascent to the surface from the seabed. The system and method do not require ancillary equipment at surface for management of gas or pressure. The fluid arrives at surface with minimal gas and pressure.
