... Venting or Draining system for product before and after each shipment. After completion of each shipment the product in the loading line is required to be drained to purge the system of any residual Hydrocarbon Vapors or VOCs (Volatile Organic Compounds). The (FEED) Front End Engineering Design required...

Regulators could adopt a no/low-venting requirement for FPSOs that would steer the industry towards an alternative solution for the storage tank blanketing. The HC blanketing option provides a simple and reliable manner to eliminate...

A well-designed compressor station will be able to reduce the venting of heavy hydrocarbons from storage tanks, which can increase safety by reducing the possibility of forming explosive vapor clouds near venting tanks. An optimized design can improve safety...

These flashed-off gases will be vented through the cargo-vent system, along with displaced gases (which are significantly higher than flash gases). The cargo-vent system is designed for vent load during cargo-terminal...

... shutdowns (ESDs) while venting the cargo tanks during calm weather. With no wind to disperse the heavier-than-air gas, the result is the mixture falling onto the vessel main deck or the process modules, triggering the FPSO gas-detection system and subsequently causing an ESD. The cost can quickly become...
