Port of Naples Marks First LNG Ship-to-Ship Bunkering

The Port of Naples has completed its first liquefied natural gas ship-to-ship bunkering operation for a cruise vessel, a milestone that strengthens Italy’s emerging network of cleaner-fuel hubs in the central Mediterranean.

Landmark Operation Fuels Next-Generation Cruise Ship

Publicly available information shows that energy trader Axpo, classification society Bureau Veritas Marine & Offshore and engineering firm Studio di Ingegneria Benvenuto & Associati worked together on the inaugural LNG transfer in Naples. The operation supplied LNG to Sun Princess, a new generation cruise ship built to run on the lower-emission fuel.

The ship-to-ship transfer was carried out using the LNG bunkering vessel Green Zeebrugge alongside the cruise ship, rather than from shore-based infrastructure. Reports indicate that the operation took place within the port area under tightly controlled conditions, demonstrating that Naples can handle large passenger vessels while managing the additional safety requirements associated with LNG.

According to published coverage, the successful operation confirms that the port can support regular LNG refuelling for cruise ships calling in the Bay of Naples. It also gives cruise lines an additional option when planning itineraries for LNG-powered vessels in the central Mediterranean, a region where bunkering availability remains more limited than in northern Europe.

Regulatory Template for Italian Ports

Industry reports indicate that Bureau Veritas conducted a technical review of a Quantitative Risk Assessment prepared by Studio Benvenuto to demonstrate compliance with Italian and international safety frameworks. The assessment considered factors such as exclusion zones, emergency procedures and interaction with nearby port traffic.

The operation in Naples followed guidelines developed by Italy’s Ministry of Infrastructure and Transport and requirements set by the National Fire and Rescue Service, aligning local practice with international LNG bunkering standards. This framework is intended to ensure that ship-to-ship transfers can be repeated safely as traffic grows.

Observers in the maritime sector view the Naples operation as an important precedent for other Italian ports planning similar services. Previous milestones at Genoa and Trieste have already demonstrated LNG bunkering for ferries and container ships, and Naples now extends that capability to large cruise vessels, helping to standardise procedures across the country’s main gateways.

Boost for Low-Emission Cruising in the Mediterranean

LNG-powered cruise ships are being introduced across major brands as part of wider decarbonisation strategies. Compared with conventional marine fuel oil, LNG can significantly reduce sulphur oxide and particulate emissions and lower nitrogen oxide and carbon dioxide output on a tank-to-wake basis, according to industry analyses.

The addition of Naples to the Mediterranean LNG bunkering map is expected to make itinerary planning more flexible for cruise operators deploying LNG vessels in the region. Reports indicate that the Sun Princess already operates itineraries in the Mediterranean, and the ability to refuel in Naples reduces reliance on a small number of LNG hubs elsewhere.

Travel and cruise sector commentators note that ports able to offer cleaner fuel services are increasingly positioning themselves as preferred calls for environmentally focused itineraries. Naples’ new capability may therefore support both the port’s competitiveness and the broader appeal of southern Italy as a destination for next-generation ships.

Operational Collaboration Underpins Safety

Publicly available information describes the Naples operation as the result of close coordination between Axpo, the cruise ship operator, the Port System Authority of the Central Tyrrhenian Sea and Terminal Napoli. Each party was responsible for specific aspects of planning and execution, from fuel supply and vessel handling to risk analysis and terminal operations.

The bunkering itself required synchronised procedures between Green Zeebrugge and the cruise ship, including controlled mooring, transfer line connection, gas monitoring and emergency shutdown readiness. Industry documentation emphasises that such operations are typically carried out with dedicated safety perimeters, temporary restrictions on nearby activities and detailed contingency plans.

By executing the transfer without incident, the Port of Naples has demonstrated that complex LNG operations can be integrated into regular cruise calls. This experience is expected to inform detailed local operating manuals and training programmes for future ship-to-ship bunkering activities in the port.

Implications for Future Infrastructure and Traffic

The successful ship-to-ship operation in Naples adds momentum to Italy’s broader shift toward alternative marine fuels. Other ports in the country have already trialled LNG bunkering for cargo and passenger ships, and analysts suggest that cumulative experience at different locations will inform decisions on additional infrastructure investment.

For the travel industry, the development is likely to influence how cruise lines design routes for new LNG-powered vessels over the coming years. Greater fuel availability in southern Europe may enable more varied itineraries that include a mix of marquee destinations and smaller ports, while still maintaining access to compliant fuel.

While LNG is viewed by many operators as a transition fuel rather than a final destination in shipping decarbonisation, the Naples milestone illustrates how ports can adapt step by step. As regulatory pressure on emissions continues to grow, the ability to offer lower-emission bunkering is expected to remain a key factor in how global cruise fleets are deployed and where they call.
