The technology group Wartsila introduces its new Wartsila 25 medium-speed 4-stroke engine. Based on Wartsila’s highly successful modular technology platform, this latest addition to the company’s engine portfolio is designed to accelerate and support the maritime sector’s efforts in achieving decarbonised operations.

The Wartsila 25 engine’s modularity offers shipowners and operators maximised flexibility, while the engine’s efficiency and fuel economy deliver minimised emissions. The engine is already capable of operating on diesel, LNG, or on either gas or liquid carbon-neutral biofuels, and can easily be upgraded to operate with future carbon-free fuels as they become available. The flexibility of having different valve timing options is a key enabler for future fuels and emissions optimisation.

The Wartsila 25 is intended to be the first Wartsila engine to run on Ammonia as a fuel – technology development is currently underway with a technology concept readiness slated for 2023, followed by planned product release soon thereafter.

“This engine marks the beginning of a new era of future-proof medium speed, small-bore engines, and comes as an important step towards the maritime industry meeting its decarbonisation goals. The Wartsila 25 ticks all the boxes. It is a small but powerful engine, and it provides an effortless transition to future fuels, making it a future-proof investment already today. Most importantly, the Wartsila 25 brings all of these advantages whilst keeping the total cost of ownership within reason.” says Roger Holm, President Marine Power & Executive Vice President Wartsila Corporation.

When operating with natural gas the engine is IMO Tier III compliant, as it also is with diesel when integrated with a Wartsila NOx Reducer emissions abatement system. Furthermore, it enables economically viable compliance with regulations such as the IMO’s CII and EEXI protocols that enter into force in 2023.

The Wartsila 25 is designed for long periods of maintenance-free operation and it supports dry-docking schedules with a time-between-overhauls of up to 32,000 hours. As a result, both downtime and operating costs are significantly reduced. Data-driven dynamic maintenance planning and predictive maintenance services can extend the TBO even further.

The Wartsila 25 features a robust and highly efficient turbocharging system with a high pressure ratio. It is now available in 6L, 7L, 8L and 9L cylinder configurations, while the dual-fuel version has a power output ranging from 1.9 to 3.1 MW, and the diesel version from 2.0 to 3.4 MW. The common-rail high pressure fuel injection technology optimises combustion and the fuel-injection settings at all loads. This in turn promotes smoke-free operation.

Other features include a self-learning proportional, integral, derivative control to reduce calibration needs, and the gathering of critical engine data for predictive maintenance, reporting and analysis purposes via Wartsila’s Expert Insight service. The modules can be replaced ‘on the fly’, which eliminates the need for separate software downloads. Optional and easy-to-apply adjustments for arctic or tropical conditions and for reducing emissions to the level of a pure gas engine are also available.

In less than 12 months, Klaveness Digital together with ZeroLab have commercialized an emissions monitoring solution that is now live in CargoValue. The monitoring solution, titled ‘Emissions’, is now measuring a significant share of emissions from global dry bulk shipping, empowering its customers to continuously track and manage their carbon footprint.

“Arming our industrial customers with crucial insight like this means they can spend their time actively looking for emissions hotspots and opportunities to reduce their footprint,” said Klaveness Digital Managing Director Aleksander Stensby.

Mitigating carbon risk in the supply chain

Monitoring of emissions was just recently added as a service to the CargoValue platform, marrying industry expertise and technical know-how to mitigate carbon risk in supply chains across all main shipping segments. “In dry bulk we’ve expanded fast and are now serving major global accounts in aluminium, grain and mining to name a few,” Stensby added.

The platform tracks greenhouse gas emissions generated by every freight shipment, using calculations based on satellite data, vessel particulars and actual behaviour. This complements and corroborates an increasing share of data coming into CargoValue from vessels reporting their actual emissions.

Putting data to use in a smart way

“Quality data is the backbone of the digitalization movement, with demand coming not only from customers, but also investors and other stakeholders. Working with us allows charterers to take action now on accurately measuring, assessing, and benchmarking their Scope 3 emissions,” adds Stensby, arguing that the industry needs to follow the example of the first movers and drop the “wait and see mentality” often linked with zero fuels or regulatory agenda.

Head of ZeroLab Morten Skedsmo, whose team has led the development of ‘Emissions’, is pleased to see more customers realize the value of accurate monitoring. “As a shipping company we are taking action on our own emissions and helping other companies do the same, we want to create value every step of the way.”

Building on the insights available through the Emissions module in CargoValue, ZeroLab’s team then apply their expertise to focus on helping charterers to explore reduction strategies, for example by establishing an emissions trajectory in line with the customer’s ESG commitments. As up to 30% of emission reductions can be achieved through improved operational efficiency, the team uses the data to guide customers on where improvements can be made across the supply chain.

Collaboration is key

Stensby, meanwhile, emphasizes the critical importance of collaboration across the value chain in driving decarbonization. “As well as quantifying supply chain emissions and assessing how they align with established frameworks for ESG compliance and industry initiatives such as the Sea Cargo Charter, CargoValue enables collaboration with stakeholders in real-time to build transparency. Some customers have incorporated their global operations and spanning hundreds of supply chain stakeholders into the platform.”

“Digital transformation, leveraging intelligent, cost-effective ways to complement work done by humans is key for survivability and profitability. With our platform of services providing end-to-end commodity visibility, we can act as an extension of customers’ own supply chain function and guide them on their digital journey towards resilience and long-term sustainability,” Stensby concluded.

PortXchange Products B.V., one of the leading tech start-ups in the maritime domain for predictable and sustainable shipping, has announced a long-term global partnership with BigMile, supplier of software for calculating and analysing transport-related CO2 emissions. Through their combined efforts, the two companies will provide digital solutions to increase transparency of shipping emissions in port areas.

With the growing pressure on the shipping and logistics industries to reduce the emissions footprint, ports are emerging as critical players to drive sustainability efforts. However, most ports currently lack the necessary means to track emissions, which is the first step in developing decarbonization strategies to meet the ambitious reduction targets set by the International Maritime Organization.

By working together, PortXchange and BigMile are ideally positioned to equip ports worldwide with a unique digital service that will allow them to monitor emissions from vessels, road, and rail transport, and help them quantify the impact of their sustainability programmes. “We are excited to partner up with BigMile – the leader in CO2 footprint standardization – and to contribute our vast experience in the maritime industry to this collaboration,” says Sjoerd de Jager, Managing Director of PortXchange.

Enhancing decarbonization through digitalization

Although most shipping emissions occur during the voyage, their negative impact is most directly noticeable in ports because these are usually located close to cities. In fact, around 230 million people are directly exposed to shipping emissions in the world’s top one hundred ports. Digitalization can significantly enhance decarbonization efforts by providing means to calculate and monitor emissions and subsequently implement measures and interventions to reduce emissions.

“With our flagship product called PortXchange Synchronizer, we offer a solution that allows vessels to optimize their sailing speed for just-in-time arrival at the port. This reduces fuel consumption during the voyage and avoids unnecessary waiting time at anchorage, which leads to lower emissions in the port area,” continues De Jager.

“Port authorities can play a significant role in facilitating JIT arrival by supporting data-sharing initiatives and offering incentive schemes such as JIT-induced port fee discounts. There are several examples of such schemes currently being trialled, including at the ports in Rotterdam, Los Angeles Long Beach, Singapore, and Esbjerg. Thanks to the insights provided by the combined digital service from BigMile and PortXchange, the effectiveness of these measures becomes transparent. These insights are critical to underpin the investment strategies for these measures,” he adds.

Supporting targeted operational and strategic decisions

“In this collaboration, our aim together with PortXchange is to encourage and facilitate ports worldwide to map their current footprint so that they can then make targeted decisions to reduce emissions in and around the port. These measures can be either operational, such as optimizing the sailing speed as Sjoerd already mentioned, or strategic in nature, because the multi-modal split of emissions creates a more comprehensive picture of where transport emissions come from. This allows ports to take a holistic approach to port call decarbonization,” states Jan Pronk, Managing Director of BigMile.

Strategic measures could include electrification and the construction of shore power systems, he explains: “Shore power systems can potentially be an important part of the energy transition. If ships turn off their generators and use shore power when they are at the quay, they are a lot less polluting. The BigMile and PortXchange platform can provide insight into how much air pollution a shore power connection can prevent. Right now, ports are facing strategic choices about whether – and if so, where – to install shore power systems.”

BigMile and PortXchange are currently working on their first implementation of this digital service in the Port of Rotterdam. The service will also become available to other ports by the end of this year.

As part of the strategy to decarbonise its customers’ supply chains, A.P. Moller – Maersk has entered a green methanol partnership with U.S. based project developer Carbon Sink LLC. This is Maersk’s 8th such agreement in the efforts to accelerate global production of green methanol.

The parties have signed a Letter of Intent covering the development by Carbon Sink of green methanol production facilities in the United States. The first facility will be co-located with the Red River Energy existing bioethanol plant in Rosholt, South Dakota, USA, and will have a production capacity of approximately 100,000 tonnes per year.

The commercial start is anticipated in 2027 and Maersk intends to purchase the full volume produced at the plant, with options for the output of subsequent Carbon Sink facilities at other locations.

“Securing green fuels at scale in this decade is critical in our fleet decarbonisation efforts. We have set a 2040 net zero target for our entire business – but importantly to stay in line with the Paris Agreement, we have also set 2030 targets to ensure meaningful progress in this decade. Partnerships are essential on this journey – and I am very pleased to welcome Carbon Sink on board.” said Berit Hinnemann, Head of Green Fuels Sourcing, A.P. Moller – Maersk.

Carbon Sink uses a commercially available technology to produce green methanol by combining green hydrogen from electrolysis of water using additional renewable electricity and biogenic CO2. The CO2 for the first project will be waste CO2 captured from the Red River Energy bio-ethanol plant, recycling those emissions into green methanol.
“We are very pleased to be working with Maersk in support of their mission to decarbonise the shipping sector. Carbon Sink brings a vast wealth of knowledge, experience and partnerships to help them achieve their ambitious corporate goals. Our multi-project development strategy creates a pathway for the supply of significant volumes of green methanol to help meet the demand of Maersk’s growing dual-fuel ship fleet.” said Steve Meyer, CEO of Carbon Sink.

Carbon Sink joins seven other strategic partners working to secure the green fuel needed for the 19 container vessels Maersk currently has on order which are capable of operating on green methanol. In March, Maersk announced six partnerships with CIMC ENRIC, European Energy, Green Technology Bank, Orsted, Proman, and WasteFuel with the intent of sourcing at least 730,000 tonnes per year by the end of 2025. A seventh partnership with Debo was added in August.
