Mitsubishi Shipbuilding receives orders for Japan's first methanol-fuelled RoRo cargo ship duo

Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, on Wednesday (19 June) said it has received orders from Toyofuji Shipping and Fukuju Shipping for Japan's first methanol-fueled roll-on/roll-off (RORO) cargo ships. 

The two ships will be built at the Enoura Plant of MHI's Shimonoseki Shipyard & Machinery Works in Yamaguchi Prefecture, with scheduled completion and delivery by the end of fiscal 2027.

The ships will be approximately 169.9 meters in overall length and 30.2 meters in breadth, with 15,750 gross tonnage, and loading capacity for around 2,300 passenger vehicles.

A windscreen at the bow and a vertical stem are used to reduce propulsion resistance, while fuel efficiency is improved by employing MHI's proprietary energy-saving system technology combing high-efficiency propellers and high-performance rudders with reduced resistance. 

The main engine is a high-performance dual-fuel engine that can use both methanol and A heavy fuel oil, reducing CO2 emissions by more than 10% compared to ships with the same hull and powered by fuel oil, contributing to a reduced environmental impact. 

In the future, the use of green methanol(2) may lead to further reduction in CO2 emissions, including throughout the lifecycle of the fuel. Methanol-fueled RORO ships have already entered into service as ocean-going vessels around the world, but this is the first construction of coastal vessels for service in Japan.

In addition, the significant increase in vehicle loading capacity and transport capacity per voyage compared to conventional vessels will provide greater leeway in the ship allocation schedule, securing more holiday and rest time for the crew, thereby contributing to working style reforms.

Mitsubishi Shipbuilding, to address the growing needs from the modal shift in marine transport against the backdrop of CO2 reductions in land transportation, labor shortages, and working style reforms, will continue to work with its business partners to provide solutions for a range of societal issues by building ferries and RORO vessels with excellent fuel efficiency and environmental performance that contribute to stable navigation for customers.

MMMCZCS publishes report on preparing tanker vessels for conversion to green bunker fuels

The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) recently released its latest publication that sheds light on the technical, economic and environmental impact of preparing tanker vessels for conversion to alternative bunker fuels.

The publication titled ‘Preparing Tanker Vessels for Conversion to Green Fuels’ aims to understand the technical requirements and cost of converting from fuel oil to methanol or ammonia and from liquefied natural gas (LNG) to ammonia.

The publication outlined the project results related to converting tanker vessels to methanol or ammonia fuels.

“To decarbonise the global shipping industry, the world fleet needs to transition to using alternative fuels,” it said.

“However, shipowners are met with a big scope of challenges as they build their decarbonization strategies and determine how to most effectively time their investments in alternative fuel and technologies.”

The report considered reference designs for two types of tanker vessels: LR2 and VLCC. 

These vessel types are two of the largest in the tanker segment, often travel long routes, and have a high fuel consumption ― therefore, they can provide a good illustration of the economic and environmental impacts of different choices relating to vessel conversion. 

For each vessel design, the center defined five levels of preparation for alternative fuels, ranging from no preparation (Level 0) to a dual-fuel newbuild ready to operate on methanol or ammonia (Level 4).

For the LR2 design, the center’s model indicated that the total add-on cost of newbuilding and conversion to operation on methanol or ammonia, depending on preparation level and range, is:

  • 14-27% of the cost of a standard fuel oil newbuild for fuel oil-methanol conversions
  • 25-42% of the cost of a standard fuel oil newbuild for fuel oil-ammonia conversions
  • 47-62% of the cost of a standard fuel oil newbuild (or 21-34% of the cost of an LNG newbuild) for LNG‑ammonia conversions

 The main takeaways from its publication are:

  • Converting tankers to green fuels is technically and economically feasible with careful fleet transition planning and consideration of asset age. The industry possesses the necessary technology and engineering expertise for these conversions.
  • The economic impact of conversions varies based on the chosen green fuel and vessel range.
  • Conversion to alternative fuels affects a vessel’s operating envelope due to differences in energy density and fuel tank size requirements.
  • To maintain the same operational range as fossil fuels, shipowners may need to add tanks on deck (impacting DWT) or sacrifice part of the cargo capacity for fuel tanks.
  • This project focuses on options that reduce the vessel’s operating range but preserve its cargo capacity. Such solutions are believed to have commercial applicability based on industry knowledge.
  • Conversions after ten years of operation on fossil fuels can still considerably reduce a vessel's lifetime greenhouse gas emissions, though financial viability of conversions at this stage of the vessel’s lifetime must be considered.

Steel cutting begins on Fratelli Cosulich methanol dual-fuel bunker tanker

Genoa-based international shipping and logistics company Fratelli Cosulich Group on Friday (19 July) said a steel cutting ceremony was held at Taizhou Maple Leaf Shipbuilding for its methanol dual-fuelled bunker tanker.

The 7,990 dwt IMO Type II chemical vessel has a capacity of over 8,000 m3 and will be able to carry both green methanol and biofuels. It will be equipped with three MAN GenSets designed for running on methanol.

The four-stroke engines will be part of a diesel-electric propulsion system, while an onboard battery storage system will optimize fuel consumption and reduce GHG emissions.

The vessel is scheduled for delivery during the last quarter of 2025 and will be located at the Port of Singapore under a contract with global commodities trader Trafigura.

“With the steel cutting of this state of the art bunkering vessel, we mark an additional important step in our Group’s journey to decarbonization”, said Guido Cardullo, Head of Marine Energy.

Manifold Times previously reported Fratelli Cosulich placing an order for its first methanol dual-fuelled chemical bunker tanker on 15 December which will operate in Singapore.

It will be deployed to deliver marine fuels for TFG Marine, Trafigura’s international marine fuel supply and procurement joint venture with shipowning companies Frontline Ltd and Golden Ocean Group Ltd.

Fratelli Cosulich Bunkers Singapore will oversee the technical management and operations of the vessel for TFG Marine.

Lhyfe and Elyse Energy plan to produce e-methanol bunker fuel from green hydrogen

Green and renewable hydrogen producer and supplier Lhyfe on Wednesday (17 July) announced a partnership with Elyse Energy, a pioneer in the production of low-carbon molecules. 

The partners aimed to develop the production of e-methanol from green hydrogen, at the Loire Estuary’s industrial and logistics port ecosystem.

In November 2023, Lhyfe was selected as the winner of a call for expression of interest (CEI) launched in late 2022 by the Nantes Saint-Nazaire port authority (Grand Port Maritime de Nantes Saint-Nazaire), to set up an industrial green hydrogen production and distribution operation at the Montoir-de-Bretagne site, with a view to decarbonising maritime transport.

With this objective in mind, Lhyfe and Elyse Energy, a producer of low-carbon molecules, announced that they have signed an exclusive agreement for the technical, economic, financial and regulatory feasibility study of a project to produce e-methanol from green hydrogen at this site within the port of Nantes Saint-Nazaire. This is the first collaboration of this kind for either of these two French industrial SMEs.

“E-methanol is a clean fuel that can be used to decarbonise maritime transport, which represents a key industrial and technological challenge for achieving the dual objectives of carbon neutrality and moving away from fossil fuels,” Lhyfe said. 

Implementation of the project will be subject to the conclusions of this study, the granting of operating licences and building permits, and financial investment decisions.

A presentation of the project by the partners is scheduled for September 2024.
