Classification society DNV and the Liberian International Ship and Corporate Registry (LISCR) on Tuesday  (15 September) have awarded an Approval in Principle (AiP) certificate to South Korea’s HD Hyundai Heavy Industries (HD HHI) for a new 12K LNG Bunkering Vessel design, tailored to the needs of cruise ships. 

The AiP was presented to Mr. Ryu Hong Ryeul, CTO / HD HHI, by Vidar Dolonen, Regional Manager for Korea & Japan at DNV, during a ceremony at Gastech 2026 yesterday.

The new concept, a dedicated LNG bunkering vessel (LNGBV) for the cruise segment, has been developed to address the unique operational challenges associated with refueling cruise ships. In particular, unlike conventional designs, the concept removes the bridge wings to avoid interfering with cruise ships’ lifeboats during bunkering operations.

To compensate for the reduced side visibility resulting from the removal of the bridge wings, the vessel is equipped with a CCTV system. In addition, side visibility safety and efficient bunkering operations have been enhanced through the addition of the HiNAS SVM (Hyundai Intelligent Navigation Assistant System Surround view monitoring system), which shows a 360-degree top-view AR image converted from inputs from multiple fish-eye cameras installed around the ship.

Mr. Ryu Hong Ryeul, CTO at HD HHI, said: “By enabling ship-to-ship (STS) LNG bunkering operations without the need for a floating pontoon, this 12K LNGBV bunkering vessel is expected to make LNG bunkering for cruise vessels more efficient and flexible. If this type of LNGBV becomes more widely adopted in the market, this could bring about significant changes in the demand structure and operating models of the LNGBV market because this new type of LNGBV is able to carry out bunkering more freely and flexibly, not only for cruise ships but also for conventional merchant vessels.”

Alfonso Castillero, Chief Executive Officer, Liberian Registry, said: “The Liberian Registry is pleased to support this Joint Development Project, which addresses the specific operational and safety considerations associated with LNG bunkering for cruise ships. The AiP represents an important milestone in advancing a practical and flexible vessel concept while maintaining a strong focus on safety, regulatory compliance and operational reliability.”

Vidar Dolonen, Regional Manager for Korea & Japan at DNV, added: “The transition to lower-emission shipping depends not only on vessels, but also on the supporting infrastructure that enables alternative fuels to be used safely and efficiently. With LNG continuing to play a leading role both the cruise sector and the maritime industry’s decarbonization efforts more broadly, this LNG bunkering vessel concept represents an important step toward building the capabilities needed for the maritime energy landscape.”

An Approval in Principle (AiP) is an independent assessment of a concept within a defined framework of requirements. It confirms the feasibility of the design and verifies that no significant technical barriers exist to its implementation.

South Korea’s Hanwha Power on Wednesday (16 September) said that it has obtained approval in principle (AiP) from the American Bureau of Shipping (ABS) for the concept design of a 22,000-cubic-meter LNG bunkering vessel at Gastech 2026 held in Bangkok, Thailand.

The certificate presentation ceremony was held on September 15 local time, with Hanwha Power Marine Solution Business Division Head Hoon-min Kim, Vice President Jong-kyu Hwang, who oversees Technical Solutions, and key ABS representatives in attendance.

With the latest AiP, Hanwha Power has completed its lineup of medium- and large-scale LNG bunkering vessels, ranging from 7,500-cubic-meter to 22,000-cubic-meter.

A key feature of the concept design is its LNG-ammonia multi-cargo capability, which enables the vessel to transport not only LNG but also ammonia, an emerging next-generation bridge fuel. 

The design incorporates high-manganese steel cargo containment technology, Mc-C, allowing the vessel to adapt to the future transition to alternative fuels with minimal design modifications. This provides shipowners with greater long-term technological flexibility and competitiveness.

Considering the operating characteristics of bunkering vessels, which primarily operate in coastal waters, Hanwha Power has also applied a hybrid electric propulsion system that integrates an onshore power supply (OPS) system with an energy storage system (ESS). The system is designed to minimize harmful emissions while the vessel is berthed or operating in coastal areas, while also improving operational efficiency and economic performance.

In addition, Hanwha Power has incorporated the Group’s core technologies, including dual-fuel generator sets, ESS, electrical power system integration, integrated automation system, and cargo handling system. By integrating these technologies, the company aims to maximize the competitiveness and business synergies of its integrated engineering and procurement (EP) package, covering both engineering and procurement capabilities.

“This ABS AiP marks another important milestone demonstrating Hanwha Power’s technological reliability and commercial viability in the global eco-friendly vessel market,” said Hoon-min Kim, Head of Hanwha Power’s Marine Solution Business Division. 

“Building on the Hanwha Group’s differentiated clean-technology capabilities, we will continue to provide global shipowners with optimized integrated solutions for the transition to more sustainable marine transportation.”

US cryogenic equipment company Chart Industries recently said the company will supply the liquid hydrogen fuel systems for Samskip’s SeaShuttle 1 and 2, the world’s first hydrogen-powered container vessels.

The company said the project will demonstrate how liquid hydrogen can enable zero-emission operations for commercial shipping, bringing together advanced storage technology, fuel conditioning systems, bunkering interfaces, and safety solutions to support reliable vessel operations. 

“Most importantly, these are not demonstration concepts. They are commercial vessels designed to operate on the Rotterdam-Oslo corridor, showcasing how hydrogen is moving from possibility to practice,” it said in a social media post. 

“We’re proud to support Samskip and our project partners as we help advance the future of sustainable maritime transport.”
