The Business of Towing: Job Costing Insights

In the towage industry, managing costs and maximizing profitability are crucial for success. With fuel, crew wages, and maintenance driving up operational expenses, accurately assessing the cost to serve each customer is essential. In this article, we will pinpoint on how towage companies can use data-driven insights to optimize job costing, implement better pricing strategies, and avoid loss-making operations. By leveraging technology and data, companies like LionRock can help unlock the full potential of their resources and improve profitability.

Tugboat Operations - Optimizing Tugboat Jobs and Towage Plans for Efficient Operations

Cost to serve on tugboat jobs

In the competitive world of maritime services, understanding the cost to serve is crucial for towage companies aiming to maintain profitability and long-term sustainability. Cost to serve refers to the total cost associated with providing a service to a customer, encompassing both direct and indirect expenses. Accurately assessing this cost is essential, as it enables companies to price their services appropriately, identify areas for efficiency improvement, and avoid unprofitable business activities.

The components of cost to serve in the towage industry are multifaceted. Direct costs are the most apparent and include expenses such as fuel, crew wages, and maintenance. These costs are variable, fluctuating with the level of service provided. For example, fuel costs vary with the distance traveled and the type of operation, while crew wages may change depending on overtime or the need for additional crew members for specific jobs. Maintenance, another significant direct cost, depends on the wear and tear of the vessels, which can vary with usage intensity and environmental conditions. While costs like administrative expenses, insurance or depreciation of assets may not fluctuate directly with the level of service, they contribute significantly to the overall cost to serve. Understanding and balancing these kind of different costs is the key to managing and reducing the overall cost structure.

Better Pricing

In the towing industry, effective pricing is a cornerstone of profitability. In order to set prices that are both competitive and profitable, companies need to consider several factors that influence pricing decisions. One of the most critical factors is the demand in the marketplace. An understanding of the dynamics of demand, including peak periods, seasonal variations and the competitive landscape, allows towage companies to strategically adjust prices.

Cost to serve is another important factor. It provides a baseline for pricing decisions. Unsustainable operations and potential financial losses result from pricing below the cost to serve. It is therefore essential to accurately calculate all associated costs to ensure that prices cover costs and contribute to profitability.

Avoiding Loss-Making Business

Losses often stem from common pitfalls such as low-margin contracts, high operational costs, and inefficient resource allocation. One of the most significant contributors to loss-making in towage is entering into low-margin contracts. These agreements, often secured to maintain market share or during competitive bidding processes, can severely impact profitability. While these contracts may ensure a steady stream of work, they frequently fail to cover the full cost to serve, leading to financial strain. It is essential to carefully evaluate the profitability of each contract before committing, considering not only the direct costs but also the indirect and variable costs associated with delivering the service.

High operational costs are another major factor that can turn a profitable business into a loss-making one. These costs include expenses such as fuel, crew wages, and maintenance, which can quickly escalate if not managed efficiently. Companies must continuously seek ways to optimize operations, such as improving fuel efficiency, maintaining equipment to prevent costly breakdowns, and ensuring that crew levels are appropriate for the demand.

Inefficient resource allocation also contributes to losses. This can occur when vessels are underutilized, or when too many resources are dedicated to low-value tasks. Optimizing the deployment of vessels and crews based on-demand forecasts and real-time data can help prevent waste and ensure that resources are used where they generate the most value.

Data and Technology for Optimization

Data plays a critical role in helping different towage companies to understand and manage their cost to serve. One of the greatest challenges is not assessing the costs but gathering the right data to make better decisions. Data-driven solutions can offer detailed insights in operational performance and resource usage. With the help of data analytics, towage companies can measure the true cost of serving each customer. This cost can include fuel consumption, tugboat idling time or crew deployment. Having such detailed cost analysis provides companies to perform a more refined customer profitability analysis and adjust the pricing strategies accordingly. Accessing and integrating this data in a usable form can be challenging. Without the right systems to gather, process and analyze data, companies risk losing valuable insights. LionRock can help towage companies to collect, analyze and interpret the data they need to make better operational decisions.

Introduction – Biofuel to power diesel tugboats

The maritime industry is undergoing a significant transformation as the European Green Deal and the IMO push towards greater sustainability. This shift is driven by the urgent need to reduce carbon emissions and mitigate the environmental impact of maritime operations. Among the various strategies being explored, the use of advanced biofuels stands out as a promising solution. Advanced biofuels, such as FAME (Fatty Acid Methyl Esters) and HVO (Hydrotreated Vegetable Oil), can power diesel tugboats and offer a viable alternative to traditional diesel fuels.

FAME is a biodiesel produced by transesterification of vegetable oils with methanol. It is renewable and biodegradable, making it an attractive option for reducing emissions. HVO, on the other hand, is produced through the hydroprocessing of vegetable oils and animal fats. It has a higher calorific value and greater chemical stability than FAME, making it particularly promising for maritime use. These biofuels are derived from renewable resources and have the potential to significantly reduce diesel tugboats’ greenhouse gas emissions.

Biofuels are gaining attention due to their ability to lower carbon footprints and their compatibility with diesel tugboat engines, which do not require modifications to function. According to the European Biodiesel Board, biofuels can reduce carbon emissions by up to 90%  compared to conventional diesel, making them a key component in the transition to greener maritime operations.

Understanding the Production Pathways of Biofuels

The diagram above illustrates the production pathways of FAME and HVO. Both biofuels are derived from vegetable oils and animal fats but follow different processing methods:

  • FAME Production: Begins with the esterification process, where vegetable oils or animal fats are converted into biodiesel through a reaction with methanol. The methanol required is produced in a dedicated methanol plant.
  • HVO Production: Involves a process of hydrotreatment and isomerization, in which the raw oils and fats are converted into biodiesel after reacting with hydrogen produced in dedicated plants. 

These processes highlight the complexity of biofuel production and the key steps involved in transforming raw materials into sustainable fuel options for maritime operations.

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.

Comparing Conventional and Hybrid Propulsion Systems in Maritime Applications

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.

AIS Marine Traffic – AIS Tracking Systems Explained


How AIS Technology Transforms Maritime Safety and Efficiency

The Automatic Identification System (AIS) revolutionized maritime safety by combining GPS and VHF radio technologies, initially focusing on collision avoidance in poor visibility and at night. Over time, AIS evolved beyond its primary role, providing critical data for traffic services and coastal surveillance, especially for vessels out of shore-based systems’ reach. This evolution was significantly propelled by the introduction of satellite-based AIS receivers in 2008, expanding global maritime visibility and data accessibility. Today, AIS is indispensable, with a ship locator mandated for a wide range of vessels to enhance navigation, safety, and operational efficiency across the maritime industry.

AIS for Avoiding Collisions

The introduction of GPS for civilian purposes led to the first AIS vessel tracking and identification system. AIS was developed by integrating GPS time and position data with long-standing VHF radio technology. Initially developed under the International Maritime Organization (IMO) in the 1990s, AIS was as a ship-to-ship anti-collision system for use in poor visibility and at night, in support of radar and conventional watch keeping. Over time, the amount of information that could be transmitted in the VHF signal grew and its usefulness increased.


In its early years, AIS was useful for (1) avoiding collisions, (2) acting as a traffic service and (3) providing coastal surveillance. Of these, the main purpose was to prevent collisions by allowing vessels to see who else is operating in their immediate vicinity, which primarily concerned large vessels at sea outside the range of shore-based systems. The technology identifies every vessel individually, along with its specific position and movements, enabling a virtual picture to be created in real time. This was achieved by providing information on the ship’s identity, type, position, course, speed, navigational status and other safety-related information. The AIS standards have further improved to include a variety of automatic calculations based on these position reports, such as Closest Point of Approach (CPA) and collision alarms.


Since not all ships have the system, AIS is usually used in conjunction with radar. However, the use of AIS is increasing, as international maritime law requires AIS transponders to be fitted aboard international voyaging ships with a gross tonnage of 300 tonnes or more, and on all passenger ships regardless of their size. Further, given its visibility and safety advantages, many smaller vessels also voluntarily install AIS units. The result is that AIS is used almost universally in the worldwide commercial maritime industry, and increasingly so in the leisure marine sector.

AIS Transceivers: Class A and Class B

Today, the AIS system consists of a VHF transmitter, two VHF TDMA receivers, a VHF DSC receiver, and a communications link to shipboard displays and sensors. It uses GPS for position and timing information, with data being broadcast automatically to ensure seamless ship-to-ship and ship-to-shore communication.

 

AIS transceivers are divided into two categories: Class A and Class B, each differing in the volume of data reported and the frequency of reporting. Class A transceivers, mandatory for all international voyage ships above 300 gross tonnage and all passenger ships, broadcast various information, categorized into static, dynamic, and voyage-related data fields. Dynamic information, such as the ship’s speed and location, is transmitted every 2–10 seconds while underway and every 3 minutes while at anchor. Static and voyage-related details are shared every 6 minutes. In contrast, Class B transceivers, often used by smaller, primarily pleasure, vessels, transmit a reduced set of data at less frequent intervals. This differentiation ensures that the vast network of maritime traffic can communicate effectively, tailoring data sharing to the operational needs and capacities of different vessel types.

Evolution of AIS Data Collection

To improve the management of AIS marine traffic, the original AIS system relied heavily on direct ship-to-ship, ship-to-coast, and coast-to-ship communication within the very-high-frequency (VHF) radio wave range. This method, however, only covered 10–20 nautical miles, making AIS data difficult to collect and highly regionalized. Despite the limited horizontal range, AIS tracking systems have a much longer vertical transmission range, reaching up to 400 km. This enabled the significant leap forward in 2008 when AIS receivers were deployed on satellites. This development vastly increased the range, as satellites equipped with AIS receivers began to capture data transmitted by onboard AIS transceivers globally, enhancing the effectiveness of AIS tracking systems.

These satellites have dual roles. In busy port areas, they supplement terrestrial AIS receivers, enhancing AIS marine traffic management by providing comprehensive global coverage. Otherwise, ports risk becoming overwhelmed by the sheer volume of data from numerous vessels. Globally, they facilitate the collection of AIS data in almost real time, bridging the gap left by the limited range of terrestrial systems.
