Planning and design of LNG bunkering facilities
The properties, characteristics and behaviour of LNG differ significantly from conventional marine fuels such as heavy fuel oils and distilate fuels as marine diesel oil (MDO) or marine gas oil (MGO).
For these reasons it is essential that all LNG bunkering operations are undertaken with diligence and due attention is paid to prevent leakage of LNG liquid or vapour and the control of sources of ignition.Therefore it is necessary that throuhout the LNG bunkering chain each element is carefully designed and has dedicated safety and operational procedures executed by trained personnel.
ISO and OGP have issued ”Guidelines for systems for supply of LNG as fuel to ships’‘ to provide guidance for the planning and design of:
- the bunkering facility
- the ship/ bunkering facility interface
- procedures for connection and disconnection
- the emergency shutdown interface and
- the LNG bunkering process control
and thereby ensuring that an LNG fuelled ship can refuel with a high level of safety, integrity and reliability regardless of the type of bunkering facility.
The LNG bunkering interface comprises the area of LNG transfer and includes manifold, valves, safety and security systems and other equipement and the personnel involved in the lNG bunkering operations.
