Abstract: A system for transferring crude oil from an onshore location to an offshore vessel comprises a buoy, a floating vapor hose supported by the buoy and configured to be connected to the vessel for discharging vapor; a subsea pipe-line end manifold (PLEM); a subsea vapor hose extending between the PLEM and the buoy, and connected via the buoy internal piping to the floating vapor hose; a subsea vapor line extending between a vapor processing facility and the PLEM and connected to the subsea vapor hose; wherein the system further comprises a drain for the removal of condensed vapor from at least one of the floating vapor hose, subsea vapor hose and subsea vapor pipeline.

Abstract: A system for transferring crude oil from an onshore location to an offshore vessel comprises a crude oil supply assembly for transferring the crude oil from an onshore oil supply to the vessel, and a vapor return assembly for transferring vapor from the vessel to a vapor processing facility. The vapor return assembly is provided with a fan configured to promote a flow of vapor through the vapor return assembly from the vessel towards the vapor processing facility. The system further is provided with a member for energizing the fan.
