Gas bunkering vessels are recognized as one of the vital components of the alternative fuel supply infrastructure in the maritime industry. Specifically, the new DNV report titled "Gas Bunkering Vessels - Facilitators of the Transition to Alternative Fuels" examines the key factors affecting the development of these vessels. With the remarkable growth of the LNG bunkering fleet, pressure on the entire fueling ecosystem has increased.
Growth in LNG Consumption and the Need for New Infrastructure
LNG consumption by bunkering vessels is expected to increase by over 500 percent between 2020 and 2024, with a further anticipated growth of 167 percent between 2025 and 2030. Given this rapid growth, fueling infrastructure has been unable to respond quickly to this demand, leading to an increasing gap between demand and available fueling capacity.

Martin Cartwright, DNV Maritime's Global Business Director, stated that "the LNG bunkering market is well-supplied today, but this picture could change significantly with the continued growth of the LNG bunkering fleet." Estimates suggest that the LNG bunkering fleet must more than double by 2030, requiring between 165 and 208 vessels worldwide. This necessitates coordinated investment across the entire fueling value chain.
The Key Role of Gas Bunkering Vessels in the Alternative Fuels Supply Chain
The DNV report emphasizes that gas bunkering vessels should not be viewed merely as fueling assets. These vessels act as a critical link between fuel producers, storage facilities, ports, and ships, helping to ensure safe, reliable, and widespread provision of alternative fuels.
Compared to traditional gas vessels, these vessels require specific designs and operational processes due to their role as fuel suppliers. Frequent transfer of fuel from ship to ship, interaction with various types of receiving vessels, and the need for safe operations in congested port environments create higher expectations for vessel design, safety systems, and crew competency.
Yuri Ilchenko, Chief Engineer and Gas Vessel Specialist at DNV, pointed out the importance of converting existing vessels into bunkering vessels, stating: "Many of these vessels have the necessary capabilities for liquefied gas operations in terms of monitoring systems, safety, and cargo handling. However, success in converting these vessels requires considering factors such as vessel compatibility, fuel transfer arrangements, vapor and pressure management, and operational readiness."
With the increasing demand for gas fuels, fueling safety must develop in tandem with this growth. The report reminds that safety, resilience, and competency alongside infrastructure must evolve to successfully scale up fueling operations.
Ultimately, the safe provision of gas fuel relies on a combination of technology, procedures, and people. Cartwright emphasizes that "operators who establish strong safety management systems and focus on developing competencies will be in the best position to expand their operations safely and reliably."
