Wartsila Japan LNG ferry 1

Maritime technology group Wärtsilä on Tuesday (19 May) said it will provide a complete LNG package, comprising the Wärtsilä 31DF engine, gearbox, and LNGPac storage, supply and control system for two new ferries being built on behalf of Ferry Sunflower, a subsidiary of Mitsui O.S.K. Lines (MOL). 

The ships are being built at Mitsubishi’s Shimonoseki shipyard in Japan, and will be the first LNG-fuelled ferries to be built in Japan, it added. 

The ferries Sunflower Kurenai and Sunflower Murasaki are about 200 metres long and will be capable of carrying approximately 763 passengers, 136 trucks and 100 passenger cars at a speed of 22.5 knots. 

They are scheduled to commence operations in 2023 on the Osaka – Beppu route.

The order with Wärtsilä was booked in the second quarter of 2020 and this newbuild project has been adopted for Japan’s energy conservation rating system for coastal ships, a demonstration test programme to enhance operational efficiency.. 

Wärtsilä said its 31DF dual-fuel engine was chosen for these ferries specifically because of its very high efficiency.

It also provides safe and continuous gas mode operation, which were other key requirements in the specification.

“Wärtsilä’s vast experience and know-how in LNG solutions for the marine sector is again recognised with this landmark order for the first Japanese built LNG-fuelled ferries,” said Keisuke Yasutake, Area Sales Manager, Wärtsilä Japan.

“We are able to offer LNG-based products and systems having a proven design and high performance, with a strong reference list that supports our value proposition.” 

“MOL is dedicated to reducing the environmental impact of its business activities, and these two ferries are being built in line with that objective,” added Makoto Yamaguchi, General Manager, Technical Division, Mitsui O.S.K. Lines.

“By operating on LNG they will have a greatly reduced carbon footprint, and the high-performance Wärtsilä engine fits our requirements perfectly.”

Wärtsilä has had lengthy and strong relationships with both MOL and Mitsubishi. Mitsubishi Shipyards, for example, has delivered ferries, LNG carriers, and a seismic research vessel all with Wärtsilä engines.

Shipfinex: The green fleet transition has a financing problem

Capt. Vikas Pandey, Founder & CEO, Shipfinex argues green shipping progress is uneven: major carriers can finance alternative-fuel vessels, while smaller owners face capital constraints.

Shipfinex: The green fleet transition has a financing problem

By Capt. Vikas Pandey, Founder & CEO, Shipfinex

The numbers on alternative-fuel orders look encouraging. Seventy-two percent of newbuild capacity ordered in the first ten months of 2025 was for alternative-fuel vessels, with LNG dual-fuel accounting for 60% of that figure. More than 1,369 LNG dual-fuel vessels are now in operation or on order globally. By most measures, the transition appears to be happening.

Look at who is actually placing those orders. MSC. Hapag-Lloyd. CMA CGM. Carriers with balance sheets large enough to absorb the cost premium of alternative-fuel newbuilds and relationships with Chinese leasing companies that extend leverage ratios unavailable to most of the industry. The Strait of Hormuz disruption this March accelerated that activity further: LNG tanker charter rates spiked above $200,000 per day and carriers with deep pockets moved to lock in fuel flexibility. Meanwhile, for vessels under 6,000 TEU, orders for conventionally fuelled tonnage rose to 28% of capacity ordered in 2025, up from 19% the year before. That is not a story of broad commitment to green fuels. It is a story about who has access to capital.

An alternative-fuel newbuild costs materially more than a conventional equivalent. Methanol-ready designs, ammonia-ready structures, LNG dual-fuel systems, each carries a cost premium above the base vessel price. For an independent shipowner financing through a traditional bank, that gap is increasingly difficult to bridge. Top-40 bank lending to shipping fell from $454.9 billion in 2011 to $284.3 billion by end-2023. The Chinese leasing companies that absorbed part of that contraction are structurally oriented toward Chinese-built vessels under long-term contracts with tier-one counterparties. Independent bulk owners, mid-tier tanker operators, feeder container companies: they are working with a materially shrunken pool of willing lenders at precisely the moment they are being asked to upgrade their fleets.

This bifurcation deserves more attention from the marine fuels industry than it currently receives. Bunkering infrastructure investment follows demand signals. Alternative-fuel bunkering at secondary ports, methanol at regional hubs, LNG outside the major transhipment centres, requires a broader fleet base of alternative-fuel vessels to justify the investment. If green fuel adoption stays concentrated among a handful of majors rather than spreading across the independent owner fleet, the economics of scaling bunkering supply infrastructure outside the primary corridors remain thin.

Capital market structure and marine fuel adoption are connected, and pretending otherwise slows both. Digital instruments representing economic exposure to vessel-owning Special Purpose Vehicles, structured within regulated frameworks like VARA in Dubai, can extend the base of capital available to shipowners below the tier-one threshold. That capital base does not replace bank lending. It reaches operators that bank lending currently does not.

The Hormuz disruption reminded the industry that fuel supply chains carry geopolitical risk. The financing gap raises a quieter but equally structural point: the demand side of the green fuel equation depends on shipowners being able to afford the vessels that create that demand. Alternative-fuel bunkering infrastructure will scale when the fleet ordering those vessels does. Right now, that fleet is smaller than the order book numbers suggest.

Report: MSC Cruises ships operated on over 9,800 mt of bio-LNG and biofuels in 2025

MSC Group’s Cruise Division used 9,839 metric tonnes (mt) of renewable fuels in 2025 across its fleet, according to its 2025 Sustainability Report published last week. 

The company used a combination of bio-LNG and biofuels across its fleet, resulting in emissions reduction of 48,714 mtCO2e compared to equivalent fossil fuels. 

Based on the Energy Transition Plan, the report showed that MSC Cruises and Explora Journeys remain on track to achieve net-zero greenhouse gas (GHG) emissions for marine operations by 2050. In 2025, MSC Group’s Cruise Division achieved the International Maritime Organization’s (IMO) 2030 carbon intensity reduction target five years ahead of schedule. 

The report said the MSC Cruises demonstrated a net-zero voyage using biomethane was possible with the launch of MSC Euribia in 2023. 

Since then it has actively engaged with fuel producers and suppliers to secure affordable high quality renewable fuels and in 2026, it began blending them into its operations at scale. 

The bio-LNG it sourced in 2025 was produced from a variety of different sustainable feedstocks, including food waste, sewage sludge, organic municipal waste and, most notably, manure. 

As most of its fleet remains conventionally powered, biodiesel represents the only drop-in solution available for these vessels today. 

In 2025, MSC Europa ran on a total of 6,856 mt of bio-LNG while MSC Opera used 1,727 mt of hydrotreated vegetable oil (HVO). MSC Seaview sailed using 572 mt of HVO and 684 mt of a B24-VLSFO blend.

Roatán marks first STS LNG bunkering operation with Carnival cruise ship

Carnival Cruise Line’s LNG-powered flagship, Carnival Jubilee, recently bunkered LNG marine fuel in Roatán, Honduras.

According to Francesco Scarso, Senior First Engineer of Carnival Cruise Line, the event marked the first-ever ship-to-ship (STS) LNG bunkering operation to take place in Roatán.

“​I recently acted as the Person in Charge (PIC) for the inaugural Ship-to-Ship (STS) LNG bunkering operation ever to take place in Roatán, Honduras—fueling Carnival Cruise Line’s beautiful LNG-powered flagship, the Carnival Jubilee,” he said in a social media post. 

“Executing a cryogenic transfer for an Excel-class vessel in a brand-new location brings immense responsibility. From coordinating with port authorities to managing strict safety zones, ensuring ESD link integration, the operation required total focus and zero room for error.”

He added that ​this successful operation marked a giant leap forward for sustainable shipping and the expansion of LNG fueling options.
