Tankerman · Operations — Line Displacement / Clearing
After completing a transfer, cargo hoses and the manifold are cleared by:
- ALeaving the line pressurized
- BDisconnecting immediately while full
- CDraining/blowing the line back to a tank (or to shore) before breaking the connection, with a drip tray under the manifold✓ Correct
- DOpening the hose to the deck
Explanation
Before breaking the connection, the hose/loading arm and manifold are drained or blown clear (back to a tank or ashore) so no cargo spills when uncoupled, with a drip tray/containment under the manifold to catch residual product. Pressure is confirmed relieved first.
