Repowering your boat or entire fleet is an important decision, and a decision you will live with for a long time. These repowering decisions could deliver improved financials and customer satisfaction for your business, in addition to enhanced performance and efficiency for your vessel. 

For the best results for your business, consider all aspects of repowering before making your final choice.

To help you with this, we have compiled the five repowering considerations below for you and everyone else in the marine industry. Whether the boat is used for fishing, towing, ferrying or pleasure, these considerations will help narrow down the repowering options that you should consider. 

We also recommend you reach out to your local Cummins Inc. marine expert if you want to discuss these further.   

Identify the goals of re-powering your boat 

The first and most critical step is to clarify what your goals are in repowering your boat. 

Start with the mission of the vessel. A ferry boat or water taxi that carries commuters or tourists may benefit from reduced noise and vibration. Meanwhile, a trawler or seiner that generates revenue through fishing could value performance and durability over weight.

Often, fleet owners and captains look for one or a combination of the following outcomes from repowering. Check these out and determine which of these are your primary goals. 

Considerations while repowering your boat

 Reducing the emission of pollutants:

  • The need to reduce engine emissions is often the key driver for repowering boats. This need could be driven by new emission regulations or emerging customer, owner or governmental demands. 

Improving fuel economy:

  • Offers dual benefits of a reduced environmental footprint and lower cost. Improved fuel economy and a lower total cost of ownership is often a key goal of repower for commercial vessels ranging from tugs to fishing boats. 

Increasing cruise speed:

  • A common repower goal for vessels that generate revenue by shuttling back and forth on a route. These could be passenger ferries, commuter boats, offshore support vessels and beyond. 

Reducing noise and vibration:

  • For boats that have people as their primary source of income, providing a comfortable and quiet ride is key. Operators of water taxis, dinner cruises, tour boats, crew boats and river cruises can turn reduced noise and vibration into quantifiable financial gains. 

Increasing reliability:

  • This is a common repower goal among different types of vessels. For commercial vessels, the financial cost of downtime makes reliability an important consideration during repowers. If a boat is on the hard or in port waiting on parts or a service technician, it is not making money. In addition, minimizing the unplanned nature of downtimes is another goal of repowers, especially during a time when constrained supply chains could result in longer lead times for parts needed.

Better total cost of ownership (TCO):

  • For many commercial vessels, this is a key consideration during a repower. Things that factor into TCO include the upfront price of the engine, fuel economy as mentioned above, midlife service, and parts pricing.

This is a long list, but it is very important to think through the primary goals of your repower early on. Having this clarity will help you make better choices in the upcoming steps of repower process.

Engine emission considerations while repowering your boat

We all want to have less impact on our planet and leave a cleaner environment for our children. 

Reducing engine emissions also has economic benefits for many boats. Customers of a whale watching tour or passenger ferry often wouldn’t mind paying extra for being on a boat with lower environmental impact. Reducing environmental impact is also good for business reputation. 

Let’s look at two of the important emission aspects while repowering your boat: 

1. Compliance with emission regulations:

Most often when your vessel is under EPA regulations, you can repower your boat using an engine that has an equivalent or better emission level with the engine being replaced. Meanwhile, emission compliance often has local aspects depending upon the local regulations you face. You can contact a Cummins Inc. repower expert to discuss the unique requirements for your need. 

2. Geographies your vessel will operate:

Emission requirements for ships often change among different geographies, including different ports. If your ship is operating across geographies with differing emission regulations, then your ship needs to comply with each of them, independent of where it is built. This need to comply with different emission regulations will impact your repower choices.

Selecting mechanical or electronic engines while repowering your boat

Engines with mechanical or electronic controls is a very common decision boat owners face during a repower. This is a frequent choice as many boats that are approaching an overhaul still have mechanical engines. There is a good reason for it; Cummins marine diesel engines have long and productive lives. For example, Seaspan Cavalier got close to 60,000 hours of operation without ever removing a head.

“Boat operators loved the mechanical engines due to simplicity in troubleshooting and ease of working with simple tools like a screwdriver,” says Brian Pinkstaff, Marine Market Leader - Cummins Sales and Service, North America. “Meanwhile, today’s modern electronic engines are more self-sufficient. A combination of sensors and displays make it much easier for the captain or the crew to monitor the engine performance. There is not much to adjust with these electronic engines, giving more time to focus on the operation of the vessel,” adds Brian.

Electronic engines bring a long list of advantages over their mechanical counterparts. Here are three of these advantages: 

Improved power density:

Engines with electronic controls are often smaller than their mechanical counterparts while producing the same or higher power output. This favorably impacts both the space claim and weight of the engine. The smaller displacement also often results in lower fuel consumption for electronic engines. 

Improved torque:

Engines with electronic controls can continuously change the fuel injection rate based on the load. This improves the engine’s ability to respond to changing load demands. This means the boat operator can benefit from the higher torque produced by the electronically controlled engine. 

Reduced noise and vibration:

Electronic engines can also operate at lower speeds than mechanical engines. This is thanks to the ability to control the injection events mentioned above. As a result, electronic engines create less noise and vibration for those onboard. This is especially critical when the ships mission is to carry people. 

Mechanical engines also have their unique use cases. They could be the right solution if you prefer not to make any additional work in your vessel and need to swing a new engine and go.  

Physical fit while repowering your boat

Boats have expertly designed engine rooms with high precision. It becomes the ultimate challenge if your new engine has significant physical differences than the existing engine or if you need to add an aftertreatment. 

“Start with checking the space available for the new engine. Newer engines often produce the same power output using less space. Then determine whether you are replacing any of the other components such as transmissions, air intake systems and beyond,” says Cedric Merveillaud, Director of Cummins Marine Europe. “Then review the weight differences, as this could impact the overall performance and stability of the boat. Finally check for differences in noise generated by the engine and power system. Engines with electronic controls often help on the noise and vibration front,” adds Cedric. 

The need to be within these physical parameters will likely help you eliminate several options. This will make it easier to choose the right repower solution.

Partner with the right company to repower your boat

Repowering a boat is easier said than done. There are lots of parameters covered above to work with while repowering a boat. To ensure repowering goes as smooth as possible, it is critical to partner with the right company. 

By partnering with a company like Cummins, that has a strong marine heritage dating back to the company’s start in 1919, you are signing-up for peace-of-mind. The right partner can help you through vessel surveys, sub-system analysis and decisions around whether to re-use various power system components. 

As you consider different partners and system integrators for repower, also check out four topics mariners should consider while evaluating partners. 

Repowering your boat doesn’t need to be a stressful decision. The considerations outlined above will get you started in your thinking. Meanwhile, your unique situation likely requires more in-depth discussions. The next step is to have a discussion with a partner local to you, with a deeper understanding of your business.

Natural gas engines from Cummins can offer considerable longevity and reliability when properly maintained – so much so they are lasting decades and counting. 

Between 2008 and 2009, more than 3,730 Cummins B Gas Plus natural gas engines were procured through OEM partners Tata Motors and Ashok Leyland and delivered to the National Capital Region of India. Deployed into the Delhi transport Corporation’s (DTC) transit bus fleet, nearly 15 years later, the engines remain in service. To date, the buses have travelled approximately 5.4 billion kilometers – yes, billion – over the last 15 years.

“Cummins engines are sought after globally for their world-class reliability and durability,” explained Puneet Jhawar, General Manager – Natural Gas. “We have learned a lot from our experience in India, among other countries adopting natural gas engines, learnings that have influenced our next generation of engines.”

Last year, Cummins announced the B6.7 natural gas engine will be available in India. Built for school buses, shuttles, and medium-duty trucks, the B6.7N boasts up to 240 hp/560 lbs-ft torque.

As the most mature, proven, and least disruptive alternative power technology available today, natural gas engines offer range flexibility and deliver a similar power, performance, and driving experience as diesel engines. Cummins natural gas engines help fleets reduced their overall environmental impact without significantly increasing the cost of operation or sacrificing performance or uptime.

The power of Cummins’ natural gas engines was on display at the India Auto Expo in Greater Noida Uttar Pradesh, India this month.

Green travel is on track: Our fuel cell systems are powering the world’s first 100%-hydrogen passenger train fleet

Holiday vacation plans? Visit us in Europe where we’re powering the world’s first fleet of hydrogen trains. The Alstom Coradia iLint trains are outfitted with Cummins fuel cell systems and run on the world’s first 100%-hydrogen-powered passenger train route. The trains convert hydrogen fuel into energy and turn existing, non-electrified infrastructure into zero-emission rail lines. These trains emit only steam and condensed water while in service and operate with low noise levels that improve both operator and passenger comfort.

The hydrogen fuel cell systems used in the trains are assembled at Cummins’ Hydrogen Fuel Cell Systems Production Center in Herten, Germany. The facility was fully operational in 2022, enabling accelerated adoption of hydrogen technologies across Europe and the globe.

North America? Check. Europe? Check. We’ve expanded our New Power footprint across the globe

This year, we drove the green hydrogen economy forward across the globe by supporting new infrastructure projects and advancing government decarbonization goals.

We have broken ground on our new gigawatt PEM electrolyzer manufacturing plant in Guadalajara, Castilla-La Mancha, Spain. Construction is scheduled to be complete by the end of 2023. The 200,000 sq. ft. facility will have the capacity to produce 500MW per year, scalable to more than 1GW per year.

Our Oevel, Belgium electrolyzer manufacturing facility expanded its capacity to 1GW thanks to the Important Project of Common European Interest (IPCEI) Hy2Tech program. IPCEI will help Cummins develop a new generation of PEM electrolyzer cell stacks to power large-scale hydrogen production systems. Operation began at our new Hydrogen Fuel Cell Systems Production Center in Herten, Germany this year, which further enables the adoption of hydrogen technologies across Europe. 

We expanded our Mississauga, Ontario, Canada campus by adding a third facility dedicated to hydrogen technology. The new facility accommodates the company’s growing staff, hydrogen production capacity and new product development, putting Cummins in a better position to support the developing hydrogen market in North America.

The wait is over - our electrified powertrains made their official debut

We unveiled the Meritor 17Xe ePowertrain integrated with a Cummins battery system. The 17Xe is designed for heavy-duty trucks with the capacity to support 44 tons of gross combined weight. The assembly also features Cummins’ new lithium iron phosphate (LFP) battery pack. 

Our clean drivetrain options offer performance and packaging advantages for diverse applications across the globe.

Electrolyzers are stateside: We’re starting production in the U.S.

We announced that we'll begin producing electrolyzers in the U.S. for the first time at our Fridley, Minnesota facility. To drive the domestic green hydrogen economy forward, we'll start at 500 megawatts (MW) of manufacturing capacity annually, scalable to 1 gigawatt (GW) in the future.

recipients holding trophies

Cummins Inc. (NYSE:CMI) announced the 2022 recipients of the company’s most prestigious technical award, the Julius Perr Innovation award. Now in its 23rd year, the award recognizes employees who demonstrated excellence in innovation and technology by developing significant intellectual property for our products.

This year’s recipients are Cummins employees Richard Ancimer, Krishna Kamasamudram, Ashok Kumar, Guoqiang Li, Tim Proctor, Michael Wilson, and Aleksey Yezerets. Acknowledgement also goes to Neal Currier, Ed Hodzen, and Vivek Sujan.

ABOUT THE INNOVATIONS

The first winning patents relate to the mitigation of sulfur accumulation on a selective reduction catalyst (SCR).

Ancimer, Currier, Kamasamudram, Kumar, and Yezerets developed methodologies to not only monitor this accumulation of sulfur but regenerate the catalysts faster, and at lower temperatures, through the synchronization of engine operating conditions during regeneration. Their work is employed on Cummins products, such as Euro IV/V/VI, EPA 2010, Tier IV, and in regions high sulfur fuel, and will likely continue playing a role in meeting future emission regulations.

Wilson developed a different approach targeted for the service channel in areas with high sulfur fuel, particularly the Euro V products in South America.  A key feature of his invention involves the deactivation of cylinders, and his work has been cited numerous times by non-Cummins patents.

For second winning technology, Hodzen, Li, Proctor, and Sujan invented the SmartTorque2 (ST2) feature, which is part of the award-winning Eaton Cummins SmartAdvantageTM  Powertrain. This feature automatically senses a variety of factors, such as grade and weight, and selects the optimum torque for performance and fuel economy. The invention was first in production in 2013 and has been a standard offering of the X15 product since 2017.

ABOUT THE AWARDS

This award was created to honor Dr. Julius Perr, who retired from Cummins in 1997 as Vice President - Fuel Systems.  Dr. Perr, who passed away in 2005, joined Cummins in 1958 after fleeing Communist Hungary.  He made Columbus, Indiana (USA) home and began a 41-year career as a Cummins engineer and leader.  In his lifetime, he was named the inventor or co-inventor of 186 granted patents and remains an inspiration to many in our industry.

This article was authored by Chuck McClaugherty, Bear Electric, a Cummins Authorized Dealer.

Smart phones, smart TVs, virtual assistants, smart thermostats, smart locks and doorbells. Our homes are now filled with smart devices. Unfortunately, most of them become useless without power to run or recharge. This is why homeowners should consider installing one smart device above all other: a home standby generator. 

As a Cummins Authorized Dealer, I install a lot of Cummins QuietConnect™ home standby generators throughout Oregon. With increasingly severe weather, rolling blackouts, and aging power grids, I can tell you without a doubt a backup generator is a worthwhile investment. 

The best part of owning one of these smart devices? You don’t have to tell it when to turn on and off. It does it automatically. 

In a nutshell, here’s the process:

When we install a Cummins home standby generator, we also install a Cummins automatic transfer switch. This transfer switch constantly monitors the electric utility power coming into the home. If it detects a break in service, it will automatically disconnect the home from the electric utility line in a split second and turn on the Cummins generator to power the home instead. The generator is fed either by a natural gas line or by a propane tank.

While the Cummins generator is powering the home, the transfer switch will continue to monitor the electric utility line. Once it detects that power has been restored, it’ll automatically disconnect the generator from the home’s electrical system and reconnect the electric utility.

You don’t have to do anything. Nada. Zilch. The generator and the transfer switch do all the work. In some cases, you may not even realize there’s a power outage until you look out the window and see all your neighbor’s houses are dark.

Just as critical as having a Cummins Authorized Dealer professionally install your backup generator and transfer switch is making sure you choose the right size generator for your home. If it’s too small, the load won’t be able to power everything in the house. If it’s too big, you’ll consume extra natural gas or propane when you use it.

The easiest way to make sure you select the right size generator is to have your dealer do it for you. But if you want to get a feel for how much generator you’re going to need, Cummins has an excellent blog post on calculating the generator wattage you need or you can use the generator size calculator at Cummins.com.

We live in a world full of smart devices. Make sure you can keep yours up and running during power outages with a Cummins QuietConnect home standby generator.
