Spill containment and hull protection
What it is
- A layered set of systems designed to detect abnormal conditions and bring cargo operations to a safe stop.
- Emergency shutdown links the ship and the terminal or bunker vessel so both sides can stop a transfer.
Where it is used
- Cargo and bunkering operations on every LNG vessel and terminal interface.
Key design characteristics
- Gas, fire and low-temperature detection across cargo and machinery areas.
- Drip trays, water curtains and material selection protecting the hull from cryogenic spill.
- ESD valves and, on transfer interfaces, emergency release arrangements.
Benefits
- Independent detection and shutdown layers reduce reliance on any single safeguard.
- Clear ship-shore agreements define responsibilities before an operation begins.
Operational considerations
- System configuration follows the applicable code requirements and the specific project design.
- Training, drills and interface checks are as important as the hardware.
