Tankerman · Safety — Bonding
Current U.S. guidance on an insulating flange or non-conductive hose section in the ship/shore connection is intended to:
- AImprove cargo flow
- BBreak the metallic path and stray-current loop between ship and shore✓ Correct
- CIncrease static charge
- DReplace the need for inert gas
Explanation
An insulating flange (or a single length of nonconductive hose) breaks the electrical continuity between vessel and shore, preventing galvanic/stray currents that could arc when the connection is made or broken. A separate bonding cable is generally not recommended.
