DNV has bestowed an Approval in Principle (AIP) upon Hyundai Heavy Industries (HD HHI) for its groundbreaking designs of liquefied natural gas carriers (LNGC) and very large ethane carriers (VLEC), showcasing innovative features such as forward accommodation and wind-assisted propulsion systems (WAPS). This significant recognition took place during a ceremony at the Gastech 2025 exhibition in Milan, Italy, highlighting the maritime industry's shift towards sustainable practices.

The AIP covers two specific designs: the 174,000 cubic meter LNGCs and the 100,000 cubic meter VLECs. Notably, this marks the first instance where HD HHI has integrated a forward accommodation layout with tiltable rotor sails, a feature that underscores the company’s commitment to addressing the industry's evolving environmental challenges. The LNGC will be equipped with four tiltable rotor sails from Norsepower, while the VLEC will utilize two, enhancing the vessels' operational efficiency and fuel consumption.

The forward accommodation concept is strategically designed to mitigate issues associated with WAPS installations, such as compliance with COLREG regulations and visibility concerns. By relocating crew accommodation to the fore section, the design not only improves the overall efficiency of wind-assisted propulsion but also contributes significantly to fuel efficiency and emission reduction, aligning with the industry's increasing regulatory demands.

In a parallel development, DNV also awarded an AIP to HD Hyundai Mipo Dockyard (HD HMD) for an ammonia dual-fuel medium gas carrier (MGC) design, which similarly incorporates a forward accommodation layout. This innovative configuration allows for greater flexibility and maximizes usable space on board, facilitating the integration of eco-friendly technologies, including carbon capture and storage units and alternative fuels.

D.J. Lee, Executive Vice President and Head of the Initial Design and Detailed Design Division at HD HMD, emphasized that this design reflects their dedication to meeting customer needs while adhering to global sustainability targets. Collaborating with DNV, the company aims to expedite the adoption of next-generation technologies that will drive a greener maritime industry.

Earlier this year, HD HHI signed a joint development project agreement with DNV and TUI Cruises to explore the integration of solid oxide fuel cell (SOFC) systems on cruise ships, further demonstrating their commitment to advancing global decarbonization efforts in the maritime sector. This series of innovations positions Hyundai Heavy Industries at the forefront of a transformative era in shipping, where environmental responsibility and technological advancement go hand in hand.
