Tankerman · Operations — Vapor Control
A vapor control system (VCS) collects cargo vapors displaced during loading and routes them ashore so that:
- AThe cargo loads faster
- BVapor emissions are recovered/destroyed instead of vented to atmosphere✓ Correct
- CThe tank is inerted automatically
- DStatic charge is increased
Explanation
A VCS captures the vapor pushed out of the cargo tank as liquid enters and returns it through a vapor connection to a shore recovery or combustion unit, reducing emissions and the fire hazard of venting on deck.
