Technology group Wärtsilä on Tuesday (20 December) said it will supply its hybrid propulsion system with methanol engine for four new heavy lift vessels being built at the Wuhu Shipyard in China. 

Wärtsilä’s innovative hybrid system will minimise the ships’ CO2 emissions, thus supporting the marine sector’s decarbonisation ambitions. The system will feature a variable-speed Wärtsilä 32 main engine capable of operating with methanol bunker fuel. 

The vessels have been contracted by SAL Heavy Lift GmbH, a German heavy lift and project cargo specialist and part of the Harren Group, in cooperation with its joint-venture partner, Netherlands-based Jumbo Shipping. There is an option for an additional two vessels. The order was included in Wärtsilä’s order book in December 2022.

This will therefore make these ships among the first to be prepared to operate on methanol, a clean burning sulphur-free alternative to conventional fossil-based marine fuels. They will also be the first methanol capable ships to employ a variable speed main engine.

The hybrid system also includes Energy Storage, a PTO/PTI generator and motor, a multidrive converter, and the Wärtsilä Energy Management System for controlling and optimising the hybrid operations. The Energy Storage system will be based on Lithium-Titanium-Oxide (LTO) batteries, which can handle higher amounts of deep cycles than normal Lithium-Ion based systems. The ESS will significantly reduce the fuel consumption and/or the necessary size of the port's electric shore connection during crane operations while also providing fuel savings at sea by reducing Engine Load fluctuations in rough seas.

For each vessel, Wärtsilä will also supply the gearbox, the controllable pitch propeller (CPP), the bow and stern thrusters, air shaft seals, as well as the sterntube and bearings.

“These ships represent the next generation in heavy lift shipping. In addition to their technical capabilities, they will feature outstanding environmental performance and help guide shipping towards a greener future,” says Dr Martin Harren, Owner and CEO of SAL Heavy Lift. “We are committed to decarbonising shipping activities, and we wish to thank Wärtsilä for their support and cooperation throughout this project.”

“We are proud to be able to support SAL with Wärtsilä’s market-leading integrated hybrid-mechanical propulsion system. This is a well-proven, future-proofing solution that enables owners and operators to lower operating costs while complying with current and anticipated environmental regulations,” says Matthias Becker, Managing Director of Wärtsilä Germany.

The ships are scheduled for delivery in 2025 and will be used mainly to support wind farm installations.

Wärtsilä is a market leader in hybrid solutions for shipping applications with installations on board more than 70 vessels, and an installed battery capacity in excess of 100 MWh. The company has a broad portfolio of fuel-flexible marine engines that offer sustainable alternatives as the industry journeys towards a decarbonised future.

NYK conducts first Japan bio bunker fuel trial on coal carrier for domestic power utility firm

Japanese shipping firm NYK on Monday (10 February) said it has started a biofuel test run on its coal carrier Noshiro Maru, which is operated by Tohoku Electric Power on 9 February.

This is the first time in Japan that a coal carrier has been used to test biofuel for a domestic power utility company. Mitsubishi Corporation Energy in the Keihin area facilitated the supply of biofuel for the vessel.

Biofuels are made from organic resources (biomass) of biological origin, such as agricultural residues and waste cooking oil, and are considered to produce virtually zero carbon dioxide (CO₂) emissions when combusted.

“Since they can be used in heavy-oil-powered ship engines, which are common on large merchant ships, biofuels are considered a key means of reducing greenhouse gas (GHG) emissions in the transition period from heavy oil to zero-emission fuels,” NYK said. 

“Using biofuel to reduce GHG emissions during sea navigation also contributes to reducing Scope 3 GHG emissions generated by transporting customers’ cargo.”

NYK added it will continue to focus on introducing biofuels and other next-generation fuels, and will contribute to reducing GHG emissions in our customers' supply chains while promoting decarbonisation in marine transport.

IBIA welcomes IMO move to draft guidance change on carriage of bio bunker fuels

IBIA welcomed agreement by IMO’s Sub Committee on PPR 12 to draft Interim Guidance on the carriage of blends of biofuels and MARPOL Annex I cargoes by conventional bunker ships.

The International Bunker Industry Association (IBIA) on Monday (10 February) said it submitted a document to IMO on the carriage of biofuels for supply to a ship for use as fuel oil on board that ship in November 2023.

This highlighted that as conventional bunker vessels were limited in carrying fuel oil of no more than 25% biofuel it presented a potential impediment to the global adoption of biofuels as fuel oil for ships and so to the ambition for the decarbonization of international shipping in the short term, as set out in the 2023 IMO GHG Strategy.

“IBIA therefore welcomes the agreement by IMO’s Sub Committee on Pollution Prevention and Response (PPR 12) to draft Interim Guidance on the carriage of blends of biofuels and MARPOL Annex I cargoes by conventional bunker ships,” it said on its website. 

The guidance allows conventional bunker ships certified for carriage of oil fuels under MARPOL Annex I to transport blends of not more than 30% by volume of biofuel, as long as all residues or tank washings are discharged ashore, unless the oil discharge monitoring equipment (ODME) is approved for the biofuel blend(s) being shipped. 

“The Interim Guidance is expected to be approved by IMO’s Marine Environment Protection Committee (MEPC 83) in April,” IBIA added. 

“IBIA’s membership represents stakeholders from across the global marine fuel value chain, and being able to draw on this technically strong and credible resource will, in its role of having consultative status to the IMO, mean that IBIA will continue to bring important matters to the attention of the wider IMO membership for due consideration.”

Two projects involving ammonia and methanol bunkering infrastructures in the ports of Huelva and Algeciras in Spain were among 39 projects to receive funding under the first cut-off deadline of 2024-2025 Alternative Fuels Infrastructure Facility (AFIF) of the Connecting Europe Facility (CEF), according to the European Commission recently. 

The first ammonia bunkering infrastructure will be in Algecirasa as part of the Andalusian Green Hydrogen Valley. The project aims to deploy a ship-to-ship ammonia bunkering system in the port of Algeciras. 

It includes a 7500 m3 ammonia bunkering vessel, an on-shore ship loading system and the piping infrastructure for the transport of ammonia from the production site to the loading dock.  

Meanwhile, the first methanol bunkering infrastructure will be in Huelva, also as part of the Andalusian Green Hydrogen Valley. The project aims to deploy a ship-to-ship methanol bunkering system in the port of Algeciras. 

It includes a 7500 m3 methanol bunkering vessel, an on shore ship loading system and the piping infrastructure for the transport of methanol from the production site to the loading dock.

The coordinator for both bunkering projects is Spanish bunker and biofuel supplier CEPSA. 

The European Commission said the EU is allocating nearly EUR 422 million to the 39 projects that will deploy alternative fuels supply infrastructure along the trans-European transport network (TEN-T), contributing to decarbonisation. 

With this selection, the AFIF will support other projects including approximately 2,500 electric recharging points for light-duty vehicles and 2,400 for heavy-duty vehicles along the European TEN-T road network, 35 hydrogen refuelling stations for cars, trucks and buses, the electrification of ground handling services in eight airports and the greening of nine ports.

Following EU Member States’ approval of the selected projects on 4 February, the European Commission will adopt the award decision in the coming months, after which the results will become definitive. 

The European Climate, Infrastructure and Environment Executive Agency (CINEA) has started the preparation of the grant agreements with the beneficiaries of successful projects.
