Barge Loading Data
Cargo Hold Vapor Header Pressure
This is an eight inch pipe that collects vapors from all of the holds on the barge. There is a pressure relief valve on this pipeline to ensure pressures in the holds do not rise above safe levels. Thus, without this safety valve, the barge’s cargo hold tanks could rupture due to the unsafe high pressures. The pressure relief valve is set to open at a pressure of 34.0 inches of water column. When this valve opens, hydrocarbon vapors are released into the atmosphere.
Vapor Line Pressure Safety Valve
The vapor line sends vapors from the cargo hold vapor header to the vapor recovery unit. There is a pressure relief valve on this line to ensure pressures in the line do not rise above safe levels. The pressure relief valve is set to open at a pressure of 27.6 inches of water column. When this valve opens, hydrocarbon vapors are released into the atmosphere.
VRU House Alarm
This is an electronic monitor in the Vapor Recovery Unit (VRU) house to detect any leaks from the VRU. The VRU house contains the equipment that condenses vapors to liquids and returns them to the cargo holds. Any vapors that are not condensed and returned to the holds are burned in an engine onboard the barge. An alarm would indicate that VRU is not operating properly. This may result in the release of hydrocarbons to the atmosphere.
