Exploring Alternative Fuels for Tugboats

The maritime industry is actively researching a wide range of alternative fuels to replace the traditional diesel fuel used in tugboats, with the aim of reducing emissions and improving sustainability. Among the fuels being considered for this transition are hydrogen, methanol, synthetic diesel, ammonia, biofuels, and batteries. Hydrogen has the advantage of zero emissions at the point of use and high efficiency, making it an attractive option for the future. However, it requires new infrastructure for production, storage, and distribution. It also poses handling and safety challenges due to its high flammability. Additionally, hydrogen has a lower energy density compared to traditional diesel, which means larger storage volumes are needed onboard vessels, posing further logistical challenges.

Methanol can be stored and transported as a liquid at ambient temperatures, using existing infrastructure, and has a higher energy density than hydrogen. However, methanol combustion still produces CO2, although less than conventional diesel. Without significant changes to existing engines or infrastructure, synthetic diesel can seamlessly replace conventional diesel. However, its production is energy intensive and often relies on fossil fuels, which can offset its environmental benefits.

Another promising candidate is ammonia, with its high-energy density and carbon-free combustion. However, ammonia is highly toxic and corrosive. It requires stringent safety measures for storage and handling.

Biofuels offer a renewable and potentially carbon-neutral option, derived from organic materials such as vegetable oils, animal fats and waste biomass. They are an attractive transitional fuel because they can frequently be used in existing diesel engines with little or no modification. The carbon dioxide released when they burn is roughly equivalent to that absorbed while growing the biomass, making biofuels more sustainable than fossil fuels. However, biofuel production can compete with food resources and lead to deforestation if not managed sustainably. This poses significant challenges in balancing food security and environmental impacts.

Battery electric tugs offer a zero-emission solution at the point of use. They can use renewable energy sources for recharging. However, the energy density of batteries is lower than that of liquid fuels, which results in a shorter range and longer refueling times. Furthermore, the environmental impact of manufacturing and disposing of batteries must be considered. Choosing an alternative fuel means balancing these factors to achieve the best environmental and operational outcomes. Ongoing research and technological advances will continue to shape the future of marine propulsion.

Hydrogen Production: Pathways and Sustainability

Hydrogen can be produced in numerous ways, each with varying degrees of sustainability. Green hydrogen, produced by electrolysis using renewable energy sources such as wind, solar or hydroelectric power, is the most sustainable option. This process splits water into hydrogen and oxygen, with zero emissions if the electricity used is renewable. Green hydrogen represents the pinnacle of sustainability. It aligns perfectly with global decarbonization goals and provides a truly clean fuel alternative for the maritime industry.

In contrast, a significant proportion of hydrogen today is produced by steam methane reforming (SMR). This involves reacting natural gas with steam to produce hydrogen and CO2. This method, which is often referred to as gray hydrogen, results in a significant amount of greenhouse gas emissions. Blue hydrogen offers a slightly greener alternative by capturing and storing the CO2 produced during SMR, but the process still relies on fossil fuels and the effectiveness of carbon capture and storage (CCS) technologies.

Another emerging method is turquoise hydrogen, which is produced by the pyrolysis of methane and produces solid carbon instead of CO2. If the carbon by-product can be effectively used or stored, this method has the potential to reduce emissions. However, it is less sustainable than green hydrogen because, like blue hydrogen, it relies on natural gas.

The sustainability of hydrogen as a marine fuel depends on the method of production. Green hydrogen, which has the potential for zero upstream emissions, emerges as the ideal solution. However, the transition to green hydrogen will require significant investment in the infrastructure for renewable energy sources and in electrolysis technology. Hybrid approaches combining different production methods may be necessary during the transition period. Ultimately, the development of renewable energy capacity and the efficiency of electrolysis will be critical to making hydrogen a truly green solution for the maritime industry.

Well-to-Wake Emission Profile of Hydrogen as a Marine Fuel

The well-to-wake emission profile of a fuel covers its entire life cycle, from its production (upstream) to its combustion (downstream). This comprehensive assessment is essential to understand the true environmental impact of hydrogen as a ship fuel. Hydrogen’s well-to-wake emissions are significantly lower than those of conventional marine fuels. This is especially true when produced using renewable energy.

Green hydrogen, which is produced by electrolysis using renewable energy sources, offers the cleanest emissions profile. The only by-products of its production are oxygen and heat, both of which have a minimal impact on the environment. At the point of use, hydrogen fuel cells emit only water vapor. There are no CO2, NOx or particulate emissions. This makes green hydrogen an exceptionally clean fuel throughout its lifecycle.

However, the emission’s profile is different for hydrogen produced from fossil fuels, such as gray or blue hydrogen. The production process for gray hydrogen is a significant source of CO2 emissions, which can outweigh the downstream benefits. Blue hydrogen aims to mitigate this by capturing CO2 during production. However, overall sustainability depends on the efficiency and reliability of carbon capture and storage technologies.

The energy density is another critical factor in the assessment of the viability of hydrogen as a marine fuel. Hydrogen has a lower volumetric energy density than conventional fossil fuels. This means that it requires larger storage volumes or higher pressures. This can have an impact on the design and operation of hydrogen-powered vessels and will require advances in storage technology and vessel design in order to optimize efficiency. Especially on tugboats that have limited space, this poses a challenge.

The understanding and optimization of hydrogen’s well-to-wake emissions is critical to the assessment of its true environmental impact. Green hydrogen offers a way to significantly reduce the maritime industry’s carbon footprint. However, the transition requires careful consideration of production methods and technological advances to maximize its benefits.

In addition, noise pollution in ports and harbors is reduced because hydrogen fuel cells operate more quietly than conventional diesel engines. This quieter operation can improve the working environment for crew members and contribute to the overall sustainability of the port.

However, the operational challenges of a hydrogen-powered tugboat are significant. One of the main challenges is the lower energy density of hydrogen compared to traditional marine fuels. Hydrogen has a higher space requirement for storage, which has implications for vessel design and cargo capacity. High-pressure tanks or cryogenic storage solutions are required to store sufficient hydrogen on board. This adds complexity and cost to vessel design and operation.

The need for specialized refueling infrastructure is another challenge. Ports will need to invest in facilities for the production, storage, and distribution of hydrogen to support hydrogen-powered vessels. This will require a significant capital investment as well as co-ordination between port authorities, shipping companies and energy providers. Safety is also a critical issue due to hydrogen’s flammability and the need for strict safety protocols during storage and handling.

Despite these challenges, data-driven evaluation of hydrogen-powered tugboats has shown promising results. The Hydrotug 1, for example, has demonstrated effective performance in reducing emissions and improving operational efficiency. Ongoing data collection and analysis will be essential for the optimization of fuel consumption, the improvement of operational profiles and the enhancement of the overall viability of hydrogen-powered tugboats.

Conclusion about the Hydrotug

Emission Abatement Systems – AES to reduce Tugboat Emissions

Emission Abatement Systems for Tugboats: Systems for Cleaner Maritime Operations and Reduction of Tugboat Emissions


Tugboat emissions have become a growing concern as the maritime industry faces increasing pressure to reduce its environmental impact and meet global sustainability targets

The maritime industry plays a pivotal role in global trade and logistics, but it is also a significant source of environmental pollution. Tugboats, essential for maneuvering larger vessels in harbors and confined waterways, contribute to this pollution with their emissions of nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter (PM), and carbon dioxide (CO2). As the world becomes more environmentally conscious, there is a growing emphasis on cleaner maritime operations. 

In the pursuit for cleaner maritime operations, tugboat companies are increasingly focusing on Emission Abatement Systems (EAS). These systems, essential for reducing pollutants emitted by tugboats, mark a significant advancement in environmental stewardship within the maritime industry. As the sector faces heightened scrutiny over its environmental impact, adopting EAS not only aligns with global sustainability goals but also ensures compliance with stringent environmental regulations set by international bodies.

Understanding Emission Abatement Systems – EAS

Emission Abatement Systems are designed to minimize the release of harmful pollutants from marine vessels. These systems target emissions such as NOx, SOx, PM, and CO2, which contribute to both human health and the environment. By implementing EAS, the maritime industry can significantly reduce its pollution footprint and contribute to global efforts to combat climate change.

EAS employs various methods to reduce emissions, primarily focusing on exhaust gas treatment and improved combustion processes. Exhaust gas treatment involves technologies like Selective Catalytic Reduction (SCR) and scrubbers to remove or neutralize pollutants before they are released into the atmosphere. Improved combustion, on the other hand, enhances engine design and fuel quality to achieve more complete combustion and reduce the production of harmful emissions. Techniques such as Exhaust Gas Recirculation (EGR) help achieve this by lowering combustion temperatures and reducing NOx formation.

Selective Catalytic Reduction (SCR)

SCR systems are highly effective in reducing NOx emissions, which are a major contributor to air pollution and have significant environmental and health impacts. SCR technology operates by injecting a urea-based reagent, often referred to as AdBlue or DEF (Diesel Exhaust Fluid), into the exhaust stream. This reagent undergoes a chemical reaction with NOx gases in the presence of a catalyst, converting them into harmless nitrogen and water vapor.

The process involves a series of steps: as the exhaust gases pass through the SCR system, the urea-based solution is injected and thermally decomposes into ammonia. The ammonia then reacts with the NOx over a catalyst, typically made of materials like vanadium, tungsten, or zeolites, to produce nitrogen and water. This method is not only efficient but also reliable, making it a preferred choice for marine applications. The effectiveness of SCR systems in reducing NOx emissions by up to 90% has made them a staple in modern emission control strategies. SCR systems are integral to meeting stringent IMO Tier III regulations, which mandate significant reductions in NOx emissions for ships operating in Emission Control Areas.

Exhaust Gas Recirculation (ERG)

EGR systems recirculate a portion of the engine’s exhaust gases back into the combustion chamber. This technique reduces the oxygen concentration and lowers the peak combustion temperature, which significantly reduces the formation of NOx. NOx is primarily formed at high combustion temperatures, so by lowering these temperatures, EGR systems can effectively cut NOx emissions.

The EGR process involves routing a portion of the exhaust gas back into the engine’s intake manifold. This recirculated exhaust gas is mixed with fresh air before entering the combustion chamber. The presence of inert gases (such as CO2 and H2O) in the recirculated exhaust gases absorbs heat during combustion, which helps lower the overall combustion temperature and thus reduces NOx formation. This method is particularly effective in marine engines, where steady operating conditions allow for optimal EGR performance.

EGR systems also have the advantage of being relatively straightforward to modify into existing engine designs. Their proven efficacy in emissions reduction and their adaptability to various engine types make EGR a viable solution for meeting regulatory requirements. EGR is a well-established technology that continues to evolve, with advancements aimed at improving its efficiency and minimizing potential drawbacks such as increased particulate emissions and engine wear.

Scrubbers

Scrubbers are another effective technology for reducing emissions from marine vessels. They operate by washing the exhaust gases with a liquid, typically seawater or a specialized scrubbing solution, which absorbs and neutralizes pollutants such as SOx and PM. This method is particularly useful for vessels that use high-sulfur fuels, as it allows them to comply with sulfur emission regulations without needing to switch to more expensive low-sulfur fuels.

There are two main types of scrubbers: open-loop and closed-loop. Open-loop scrubbers use seawater directly to wash the exhaust gases, relying on the natural alkalinity of seawater to neutralize the sulfur oxides. The cleaned exhaust gases are then released into the atmosphere, and the wash water is discharged back into the sea after treatment to remove harmful components. Closed-loop scrubbers, on the other hand, use a recirculating scrubbing liquid, usually containing an alkaline substance like sodium hydroxide, to treat the exhaust gases. However, open-loop scrubbers have faced criticism due to their potential impact on marine environments, as the discharge from these systems can harm aquatic ecosystems. This concern has led to stricter regulations in some regions.

Scrubbers can reduce SOx emissions by up to 98%, allowing ships to meet IMO regulations that limit sulfur content in marine fuel to 0.5% globally and 0.1% in designated ECAs. This technology not only helps in regulatory compliance but also offers a cost-effective solution for operators, as it allows the continued use of high-sulfur fuels while still meeting tugboat emission standards.

Benefits of Emission Abatement Systems for Tugboat Operations

Implementing EAS ensures that tugboats comply with international regulations such as those set by the IMO, designed to minimize marine pollution and protect the environment. By adhering to these standards, operators not only avoid penalties but also contribute to global environmental protection efforts.

Beyond regulatory compliance, EAS significantly reduces the carbon footprint of tugboat operations by lowering tugboat emissions of CO2 and other pollutants. This leads to improved air quality in port areas and coastal regions, benefiting both the environment and public health. Cleaner operations also enhance the industry’s image and demonstrate a commitment to sustainability.

Moreover, EAS enhances the operational efficiency of tugboats. Improved engine performance and increased fuel efficiency translate into substantial cost savings over time. By optimizing fuel consumption and reducing maintenance needs, operators can achieve significant economic benefits while maintaining compliance with environmental standards.

When maneuvering ships into and out of ports, pilots and tugboat captains first and foremost responsibility is to do this in a safe manner. Nonetheless, there is a growing recognition that maneuvers should also be executed with as low emissions as possible. Hence, towage and the pilot industry are taking initiatives to adopt greener practices. This article explores the various strategies these industries are employing to mitigate their environmental impact, highlighting the existing efforts and the importance of integrating data into these.

Collaborative Efforts to Reduce Emissions

Fuel consumption in maritime operations can be significantly influenced by the collaborative efforts of tugboat captains and maritime pilots. The efficiency of maneuvers in port, including the level and nature of tug assistance, directly impacts fuel usage. Additionally, the expectations set by pilots regarding tugboat speed and power usage during operations can drive significant changes in fuel consumption.

To address emissions effectively, a broader, industry-wide approach is necessary. Accordingly, to help reduce the emissions of tugboats and pilot ships, the European Tugowners Association (ETA) Nautical Technical Committee has worked together with the European Maritime Pilots Association (EMPA), to establish practices to improve energy efficiency. Their advice is condensed in a collaborative report, which defines a series of recommendations for tugboat captains, pilots, and harbor masters to help them optimize the energy efficiency of the tugs and the assisted vessels during harbor operations. These recommendations are based on 3 main principles: Planning, Cooperation and Communication.

Furthermore, initiatives like the Greenport project exemplify how bringing together academia, industry, and training providers results in a comprehensive strategy to reduce emissions of port services. Greenport emphasizes behavioral changes through education and the strategic use of existing digital technologies to create substantial emission reductions. 

As both of these initiatives highlight, the industry is well aware of its responsibilities in reducing emissions. It is making several attempts at how to achieve these goals, specifically focusing on making operations more energy efficient. Both approaches aim at reducing the fuel consumption of sailors, whether through increased planning or training of the captains. However, as we lay out in the following section, either attempt would greatly benefit from having data on the sailing behaviors of captains.

Role of Data in Promoting Sustainable Port Practices

To achieve the desired emission reductions that port operations are seeking with their initiatives, integrating data into their solution is essential. Doing so not only supports the behavior changes in the short term but also provides a measurable framework to further enhance operational efficiency and achieve environmental sustainability in the long term. 

First, data plays an important role in setting benchmarks and monitoring the progress of the initiatives. By establishing clear performance metrics, tugboat operators and maritime pilots can regularly review their energy efficiency. This will help measure the impact of the given advice, and help establish best practices. This includes tracking fuel consumption, and emissions data during different types of ship maneuvers. In addition to setting benchmarks, these targets highlight areas for improvement. 

Second, using performance data can enhance training programs developed by European bodies like the ETA and EMPA. By obtaining and analyzing specific data, training modules can be tailored to address common inefficiencies or errors in operations. Such a personalized training approach ensures each sailor receives guidance based on their performance, leading to more fuel-efficient tug masters and pilots. Even the most skilled operators can learn from data on their sailing patterns.

How Data Can Improve Sailing Performance of Tugmasters and Pilots

Following the integration of data to set benchmarks and tailor training, maritime pilots can apply these insights to refine their operational strategies for tugboats further. Specifically, data related provided within the context of certain pilot commands – such as the timing and intensity of tugboat use in various port maneuvers – can help pilots identify optimal patterns that maximize fuel efficiency. Such a detailed analysis of pilots’ data can help illustrate the precise effects of their directives on fuel consumption, such as the differences between requiring full power for short durations versus moderate power for extended periods. 

When provided with this understanding, pilots can make informed decisions to adjust their sailing behavior, thereby reducing unnecessary fuel use and emissions without compromising on service quality or safety. Such a proactive use of data not only complements the established benchmarks but also enhances ongoing efforts to optimize operational practices in real-time, leading to sustainable improvements across maritime operations.

Conclusion

The integration of data into port operations is not merely an option, but a necessity for promoting sustainable practices. By setting clear benchmarks and monitoring progress, maritime operators can ensure their initiatives lead to measurable improvements in energy efficiency and environmental sustainability. The continuous analysis and application of performance data play a critical role in refining operational strategies and enhancing training programs, ultimately leading to more efficient and environmentally friendly port activities.

Hybrid Tugboat: Pioneering the Future of Maritime Sustainability


An overview of the recent developments for green hybrid tugs

Hybrid propulsion tugboats are at the forefront of transforming the maritime industry. By integrating alternative fuels and cutting-edge propulsion technologies, these tugboats offer significant environmental and operational benefits.

The Paris Agreement of 2016 has intensified global efforts to reduce GHG emissions, making it a critical issue for the shipping sector. In response, the International Maritime Organization set ambitious goals in 2018 to halve GHG emissions from international shipping by 2050, with the ultimate goal of achieving zero emissions by the end of the century.

Therefore, hybrid propulsion comes into play because of its promise of reducing emissions. Hybrid vessels can operate on electrical power combined with conventional fuel or utilize a blend of traditional and alternative sustainable fuels. Tugboats, given their near-shore operations and regular recharging needs, were among the earliest maritime vessels to adopt battery technology. The first hybrid tugboats began operations as early as 2009, with fully electric, zero-emission models following in 2019.

This article explores the innovations in the field of hybrid green tugs, focusing on both the environmental and operational benefits, as well as the challenges. To do so, industry examples and case studies will be provided.

Hybrid Tugboat models through the years

Through the years, tugboats have increasingly relied on batteries and various fuels to reduce emissions and enhance efficiency.

In 2010, the US-based company Foss Maritime’s hybrid tugboat Carolyn Dorothy, powered by diesel engines and batteries, demonstrated significant environmental benefits. It retained the power and maneuverability of conventional tugs while dramatically reducing emissions, noise, and fuel consumption. The hybrid electric tugboat achieved a 73% reduction in particulate matter, 51% in nitrogen oxide, and 27% in carbon dioxide. 

In 2015, NYK Line and IHI Power Systems Corporation developed Sakigake, the first Japanese LNG-fueled tugboat. Using LNG, Sakigake reduced sulfur oxide emissions by nearly 100%, nitrogen oxide by 80%, and carbon dioxide by 30% compared to heavy oil. Currently, IHI Corporation is working on developing a hybrid ammonia-powered tugboat. Ammonia, which emits no CO₂ when burned, shows promise as a next-generation fuel for reducing shipping’s environmental impact. 

Another example of the industry’s commitment to innovation and sustainability is offered by Seabulk’s hybrid diesel-electric tugs Spartan and Titan. These new green hybrid tugs, which started to operate in the USA in 2022, combine the benefits of diesel and electric propulsion for enhanced efficiency and reduced emissions. They offer exceptional power and maneuverability, fitting the high-powered needs of their customers while improving fuel efficiency.

Another example is the Hydrotug 1, operating in Antwerp since 2024, which features dual-fuel BeHydro engines that run on hydrogen or traditional fuel. This tug is part of the Port of Antwerp-Bruges’ plan to transition to a climate-neutral port by 2050.

The Panama Canal Authority’s new hybrid tugboats are another example of the growing adoption of this technology in high-profile operations. In October 2023, the Authority contracted for ten hybrid electric tractor tugboats, aiming to reduce emissions during ship towage through the canal and docking in Panamanian ports. Corvus Energy plays a crucial role in the performance of these 30-meter long hybrid tugboats by supplying advanced battery systems. These battery systems enable the tugboats to operate efficiently and sustainably. Corvus Energy CEO, Fredrik Witte affirmed that the battery systems significantly decrease vessel emissions, supporting the Authority’s goal of achieving net-zero GHG emissions by 2050.

Finally, one last notable project that has yet to come to fruition is Svitzer’s methanol hybrid fuel cell tug. The company is designing the world’s first methanol hybrid fuel cell tug, aiming to combine the environmental benefits of methanol with the efficiency of fuel cells. This new hybrid electric tugboat is expected to enter operations in 2025, helping the port of Gothenburg to fulfil the ambitious target to reduce shipping emissions within the port area by 70% by 2030.

Insights:

The graphic illustrates a comparison between conventional propulsion systems and hybrid propulsion systems for hybrid tugboat in maritime applications. The conventional system, depicted in the top diagram, consists of a main engine connected to a shaft, Zpeller, and an auxiliary generator to manage the hotel load. The hybrid system, shown in the bottom diagram, integrates a motor/generator and a battery into the propulsion chain. This system allows for a smaller main engine, with the motor/generator and battery providing additional power as needed. The auxiliary generator remains in place to handle the hotel load, while the hybrid configuration enhances efficiency and reduces emissions by optimizing the power sources.

 

The Challenges of adopting green hybrid tugs

The promises of adopting green hybrid tugboat are many, but there are also some downsides, both when it comes to hybrid electric tugboats which rely on batteries, and when the hybrids rely on non-conventional fuels. 

The very first downside, for all hybrid tugboats, is the need to invest on two propulsion systems and their maintenance. In the case of electric hybrid systems, for example, these have higher start-up costs due to the expensive Battery Energy Storage Systems. Additionally, crew training for these highly automated systems can be costly. And the need for significant space to install batteries also adds to the vessel’s weight.

But, when it comes to relying on alternative fuels, instead, these might not be as green as expected. If Hydrotug 1 or the Japanese ammonia-fueled tugboat are taken in examination, it is arguable that their reliability on hydrogen is a downside because this is very energy-intensive to produce and difficult to transport. Despite this, hydrogen produces no emissions when burned, and it can even be produced in an entirely green way, through sustainable processes or renewable resources. This shows the importance of assessing “well-to-wake” and “tank-to-wake” emissions to understand the environmental impact of fuels when evaluating the performance of a hybrid tugboat.

But, apart from the disadvantages, the benefits of hybrid tugboats are the primary reasons why they are attracting owners and operators globally. And with thorough data analysis, research, and development, companies will be able to elevate the hybrid sector to its full potential.

Operational Profiles and Data Utilization

Hybrid propulsion technology has been deployed on tugboats to reduce emissions and enhance the efficiency of operation. The operational profile of a vessel plays a significant role in determining the efficiency and emissions of hybrid propulsion systems. By analyzing and optimizing these profiles, maritime operators can improve fuel efficiency and reduce emissions. Continuous monitoring and optimization of operational profiles are vital in achieving the full potential of hybrid tugboats. Doing this in the right way results in an improved performance of the ship in terms of fuel consumption, emission regulation, operational flexibility, and reduced noise and vibration.

Operational efficiency of hybrid electric tugboats can be improved, for example, by implementing power management strategies that are able to optimize the running hours of the engines to run them at optimum efficiency. Or also, by knowing when to change the primary source of energy for the propulsion between high and low-speed operations.

Conclusion - A Greener Future with Hybrid Propulsion

In conclusion, the potential of hybrid propulsion in reducing emissions and improving efficiency is immense. These green hybrid tugs have demonstrated benefits in lowering fuel consumption, cutting emissions, and improving operational performance. By integrating alternative fuels, advanced battery systems, and data analytics, hybrid tugboats can significantly lower their environmental impact while maintaining high operational efficiency. 

Continuous innovation and effective data utilization are essential in maintaining and enhancing their performance. As the maritime sector increasingly pursues carbon reduction initiatives, the number of hybrid tugboats worldwide is projected to grow significantly. The maritime industry is poised for a greener future, driven by the adoption of hybrid propulsion technologies.

Green Ports: Decarbonizing Ports through Data


A look into the maritime shipping industry, the environmental effect of inefficient ports, and how maritime companies use technology to combat this issue.

The International Maritime Organization (IMO) aims to have net-zero shipping emissions in under three decades. Yet, the global shipping industry produces over a gigaton of greenhouse gasses every year. While barriers to advancements for this goal are in no short supply, companies such as Techbinder and LionRock Maritime are already using data to reduce carbon waste.

Maritime Shipping as a Greenhouse Gas Contributor

According to the IMO, maritime shipping accounts for nearly 3% of all global greenhouse gas emissions. This is about 1.2 gigatons of human produced gasses, of which approximately 800–850 tons are carbon dioxide. Left the way it is, without policy or technological intervention, all shipping emissions are predicted to increase by 16% before 2030. The sheer volume of greenhouse gasses that comprise the shipping carbon footprint is a aggravating the climate problem and in need of solutions.  Ports are a primary cause of maritime shipping emissions, contributing to 2% of all greenhouse gas emissions, worldwide. Ports play a large, and essential, role in the shipping industry. This is why port decarbonization is a key component of lowering maritime emissions and creating a greener industry.

Port Decarbonization: a Closer Look

Port decarbonization is the process of eliminating environmental impact associated with activities in port, such as tugboat operations, and cargo handling. A key part of this is reducing carbon emissions. The goal is to transition ports to more sustainable and eco-friendly practices, for both local and global communities.

Workboats form a critical part in port decarbonization: A 2002 study in British Colombia and Washington State showed that 28% of port CO2 emissions were from harbor craft and tugboats, making them the second-largest port CO2 contributor, behind container ships.

Each step towards port decarbonization is a step towards a shared environmental goal. There are several strategies to achieve this. They include the use of renewable energy sources, more efficient technologies, and improved logistics to minimize emissions and environmental harm. Each solution comes with its own limitations, making some advancements easier to adopt than others. However, one major tactic to reduce emissions, optimizing operations through the use of data, is already in use.

Technology for the Environment

New technology helps ships pollute less. By using data, shipping companies can learn important things about how their ship’s operation. From granular data about ship’s maneuvering to the utilization and performance of its machinery. The insights gained can help see blind spots and areas for improvement.

While there are similarities between ship types, each of those also has unique characters that requires a tailored optimization approach. While route optimization is (still) considered a major source of fuel optimization and emission reduction for long haul ships to decrease emissions, it is probably less relevant for harbor tugboats. Harbor Tugboats typically operate over relatively short distances within ports, meaning they have less extensive routes to optimize.

Reducing the Carbon Footprint of Tugboats

Today, it is difficult to accurately measure and thereby help decrease the fuel consumption of tugboats. Tugs are designed for a wide range of operations and similarly have a wide spread in their consumption range. Fuel consumption meters, widely used in other shipping segments, have found low adoption in the tugboat sector. The high investment cost as well as the installation from a barrier. Not only are these units expensive, they are also time-consuming to install.

We wanted to address the challenges and promises of accurately measuring fuel consumption without having to rely on expensive fuel consumption meters. In doing so, trying to make data more accessible to tugboat owners, thereby contributing to the goals of port decarbonization and the creation of green ports. LionRock Maritime’s expertise is tug operations data. Applying machine learning and contextual data analysis, LionRock explored correlations between tugboat speeds, power variations, and the unique characteristics of the vessels they assisted, aiming to reduce the shipping carbon footprint. While the direct correlation between tugboat speed and power during light sailing is strong, large variances occur during vessel assistance. LionRock’s innovative models using contextual and engine data separately showed promising results. However, the fusion of these models provided strong predictions of fuel consumption per job, marking a significant breakthrough in accurately estimating tugboat fuel usage, thus contributing to port decarbonization efforts and the reduction of the shipping carbon footprint.

An obstacle to obtaining RPM data lies in its collection from the tug’s engine, necessitating an installation process. To streamline this installation process and ensure the tug remains in operation, LionRock partnered with Techbinder. A tech scale-up from the Netherlands with backing from Schneider Electric that produces and installs industrial grade and cyber-secure data-loggers. LionRock has built a set of software that decodes the data and understands the tugboat operations, helping to turn data into actionable advice. By combining hardware and software, this joint endeavor promises a low-cost solution for assessing tugboat fuel consumption without disrupting tugboat operations, thus advancing the vision of green ports.

The Future of Maritime Shipping

The future of the shipping industry is a low carbon footprint. Port decarbonization is an essential part of this process. As awareness and prevalence of environmental issues continues to grow, ports will have to level up to reduce their environmental impact. The International Maritime Organization has already set net-zero emission goals by 2050, for the entirety of international shipping. This is in alignment with the Paris Agreement, which calls for immediate emission reductions as well as net-zero greenhouse gas waste no later than 2050. In some countries, emissions cost the environment and businesses. The European Union has already instrumented fees for excessive CO2 emissions, adding financial pressure to reduce waste.
