Engineering studies of LNG infrastructure at the Port of Genova


The main objective of the basic studies has been to analyse the LNG receiving system, the LNG ship bunkering system and the LNG non-ship refuelling system in the for the port of Genova.

The basic engineering study has designed an LNG receiving system that will serve the ports within the Tyrrhenian-Ligurian grid and non-Italian networks (e.g. France). LNG will be loaded from large coastal storages in other Mediterranean zones in order to supply various Tyrrhenian-Ligurian LNG small-scale terminals, which in turn will offer LNG supply for vessels and for land transport and industrial uses. Without this infrastructure, LNG supply services will be provided by road trucks operating on long distances with environmental detrimental effects as transport emissions will increase and coastal roads will suffer from additional congestion. Ship-to-ship bunker delivery services will thus represent a much more environmentally-friendly solution in Tyrrhenian-Ligurian ports and they will act as a catalyst easing the LNG uptake in the maritime sector.

Similarly, the LNG ship-bunkering system is represented by the LNG bunker ship for larger volumes (medium and large ships e.g. cruises and ferry vessels) or by tank trucks and ISO container tanks to be transported by rail or sea for smaller volumes (small ships, e.g. tugboats and harbour vessels). The LNG bunker ship represent as well the “floating storage” for the port of Genova.

Additional studies concerns the adaptation, to fit for the purpose of the west Mediterranean area operations, the engineering studies of the small LNG bunkering barge being carried out in PoseidonMedII Action in the context of the Adriatic-Ionian Sea basin.

The following basic characteristics of the bunkering ship have been considered as the starting point of this task: 6,500 m3   and 4.000 m3 LNG capacity; equipped for loading at large terminals and discharging in satellite LNG small scale systems as well as for ship-to-ship operations; capable of easy manoeuvring and equipped with hoses, fenders and other equipment necessary for bunkering activities. For the 6.500 m3 ship, a Cost Benefit Analysis has been performed as well. Basic risk analysis of ship-to-ship operations with the three type standard ships (large, medium and small passenger and Ro-pax vessels) has been performed.

In terms of safety, combined refuelling operations (LNG & traditional fuel) for LNG ships and the possibility to refuel multiple ships simultaneously have been addressed in line with the new Port Masterplan and the related risk analysis together with the update of the potential LNG demand in the medium-long term for the Genoa ferry market.

Finally, as concerns the LNG non-ship refuelling system, the study envisaged the basic and standardised design of a prototype system that will be able to refuel LNG trucks that could be located either in the port area or in the extended port hinterland.

With the purpose of sharing the main studies results and feedbacks and to foster the LNG uptake in the Mediterranean trough the dissemination of the lessons learned from the GAINN4MOS experience, an executive summary report and dissemination material will be available in this section of the website soon.
