FAQ
Answers to guide your maritime journey
What is an LNG bunkering vessel?
An LNG bunkering vessel is a specialized vessel that transports LNG and delivers it as fuel to other ships. It combines LNG cargo containment and handling systems with dedicated transfer, pressure-control, boil-off gas management and safety systems for ship-to-ship bunkering.
What is the difference between an LNG bunker vessel and an LNG bunker barge?
An LNG bunker vessel is generally self-propelled and can operate independently between LNG terminals and receiving ships. An LNG bunker barge may be non-self-propelled and rely on tugs or other port infrastructure, making it primarily suited to local operations. Terminology and configurations can vary between markets.
How does ship-to-ship LNG bunkering work?
During ship-to-ship LNG bunkering, the bunker vessel moors alongside the receiving vessel and the transfer systems are connected. After safety checks and cool-down, LNG is transferred under controlled pressure and flow, with vapour managed as required. Once bunkering is complete, the transfer system is drained, purged and safely disconnected.
What equipment is needed for LNG bunkering?
LNG bunkering requires dedicated transfer hoses or loading arms, manifolds, piping and valves, emergency shutdown (ESD) systems, gas and leak detection, and appropriate fire protection. Depending on the system, vapour return, custody-transfer metering and emergency release or dry-disconnect arrangements may also be included.
What does LNG bunkering system design cover?
LNG bunkering system design covers cargo tank selection, transfer capacity, piping and manifolds, pressure control, boil-off gas management, vapour return and safety systems. The design must also consider compatibility with receiving vessels, terminal interfaces and applicable class and statutory requirements.
What sizes of LNG bunkering vessels are typical?
LNG bunkering vessels range from small units with a few thousand cubic metres of LNG capacity to larger vessels exceeding 10,000 m³. The appropriate capacity depends on bunker parcel size, receiving vessels, port infrastructure, operating range and expected bunker demand.
