Harbor Harvest: Sustainability and small business on The Sound

Harbor Harvest

A retail center, a transport company, a boat builder and an engine manufacturer walk into a bar... Oh, wait. That was supposed to say they start shipping locally sourced produce across the Long Island Sound using a one-of-a-kind sustainable hybrid vessel to provide  environmentally friendly access to goods during the COVID-19 pandemic.

Meet Harbor Harvest: Connecticut’s innovative solution bringing the farm to the harbor, and then to your table. 

Bob Kunkel has lived in Norwalk, Connecticut for 27 years. A man with a unique background who loved spending time on the water, but also in the kitchen. This duo of passions led him to marry a food market dedicated to selling quality foods and a Marine Highway program on the northeast coast. 

Harbor Harvest HybridFirst, what is this hybrid vessel? Kunkel is the President of Alternative Marine Technologies, which specializes in projects outside of normal propulsion history or ship design. Upon connecting with BAE Systems (an advanced technology company), the two organizations thought to convert BAE’s electric vehicle bus system into a marine project. After working with an initial engine manufacturer, Kunkel and BAE found Cummins Inc.’s fully integrated marine system to be the final piece of their million-dollar idea. Using two QSB6.7 hybrid-ready engines and a display package to monitor the engines, hybrid components and energy storage system, the diesel-electric catamaran was born. 

The hybrid carries approximately 28 pallets of locally sourced goods, 10 of which are positioned in a fully refrigerated and protected walk-in space. The ship acts as a transport channel for family farms and agriculture systems bringing their sustainable goods to the big city. Kunkel mentioned that a local farm’s market generally only achieves a 10-mile radius. With Harbor Harvest, the marine highway allows them to extend their reach without increasing their costs. 

From a sustainability standpoint, the benefits are clear. A trip that Harbor Harvest can complete from Norwalk, Connecticut to Huntington, New York in about an hour takes their trucking counterparts anywhere from 6-12 hours to accomplish. But emissions on the highway aren’t the only thing Harbor Harvest is saving; they’re also improving efficiency of local farmers. Family farms aren’t having to dump their milk or discard their produce because they can’t make it to market. Harbor Harvest is providing their food a reliable and profitable route to people’s tables. 

During the COVID-19 pandemic, the Norwalk-based organization has thrived. While the boat has only been running one or two days a week due to decreased demand from restaurants and retail, they have certainly not run out of essential items.

Harbor Harvest 1st Location

"Large meat processing plants were having issues with closures," Kunkel said. "We’re direct to the farms and custom slaughterhouse, so we didn’t have any problems supplying meat, fish and other products." He followed that local vendors could respond better to the local emergency, saying this accentuated "what 'buy local' and 'support local' really means.”

Harbor Harvest is a perfect storm of sustainability, small business and innovation. Improving the relationship between the farmer, the harbor and the customer is no small task, yet Kunkel and his corporate partners seem to have concocted a flawless operation. Harbor Harvest looks toward the future, hoping they will continue to expand their business with additional hybrid vessels.

With a casual tone but the most serious of intentions, Kunkel concluded, "I think we’re pretty close to changing the world."

California’s natural gas trucks went carbon negative in 2020

Cummins Renewable Natural Gas - California

Vehicles in California powered by renewable natural gas (RNG) removed more carbon dioxide from the atmosphere than they emitted for the first time in 2020, a direct result of the continued drop in carbon intensity of renewable natural gas. 

Adoption of RNG in trucks, buses and other vehicles grew 25% across the state from 2019 to 2020, and RNG use is up more than 170% in the past five years, according to new data from California's Air Resources Board (CARB). 

Meanwhile, the carbon intensity of natural gas derived from renewable sources continues to drop. RNG is increasingly made using methane captured from agricultural waste, landfills and wastewater treatment plants. By capturing gases that may otherwise be released into the atmosphere, RNG can even deliver sub-zero carbon emissions. 

Ninety-two percent of all on-road fuel used in natural gas vehicles in California last year was renewable natural gas.  

"This verified data means California's trucks and buses leave a zero-carbon footprint while virtually eliminating criteria pollutant emissions that contribute to asthma, heart disease, and poor air quality,” said Dan Gage, President of NGVAmerica

In addition to their negative greenhouse gas (GHG) emissions, ultra-low NOx natural gas engines perform at levels that are 95 percent below the federal nitrogen oxide (NOx) standard and 98 percent below the federal particulate matter (PM 2.5) standard. 

According to NGVAmerica, RNG used as a motor fuel in California in 2020 displaced 1.83 million tons of carbon dioxide equivalent (CO2e). To put those numbers into perspective, California RNG motor fuel use: 

  • lowered greenhouse gas emissions by the equivalent amount generated by driving the average passenger car 4.6 billion miles
  • eliminated CO2 emissions, equal to 205.7 million gallons of gasoline consumed, or the energy use of 220,118 California homes in one year
  • sequestered the amount of carbon captured by 2.24 million acres of U.S. forests in one year 

The success of RNG in California is part of a broader trend happening across the United States. According to The Coalition for Renewable Natural Gas, 53% of all on-road natural gas fuel used in 2020 was RNG. Increased availability in RNG has led large nationwide fleets like UPS and Amazon to make significant investments in the number of natural gas powered trucks in their fleet.  

Natural gas vehicles fit seamlessly into current transportation, people and goods movement models because they don’t require radical changes in vehicle technology, transportation infrastructure or support networks.

Repowering your boat? Start with these five considerations

Repowering your boat? Start with these five considerations

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.

How to reap the benefits of a lightweight engine

How to reap the benefits of a lightweight engine

Power-to-weight equals more than just productivity

Operating vocational trucks is all about getting the job done as reliably, quickly and productively as possible. Nailing the power-to-weight ratio on the sweet spot can have a major impact on not just your equipment’s productivity but its longevity and your bottom line as well. There are a number of factors that come into play when spec’ing a vocational vehicle that help ensure that performance capability matches the duty cycle and jobsite conditions. It starts with choosing an engine that has the ideal power-to-weight ratio and pairing it with the correct transmission and tires, based on the most demanding aspects of its operating usage. 

Weighing In 

Regardless of whether you are spec’ing a dump, refuse truck, mixer or bulk hauler, there are substantial advantages to using a lighter-weight engine – provided it has sufficient power. In applications which typically gross out, a lighter weight engine gives you the opportunity to carry more payload (equal to the weight savings). Less weight on the front axle also reduces stress and wear over time, reducing maintenance costs. The weight savings/increased payload can be as much as 630 lbs. per trip in a vehicle, when switching from a Cummins ISX12 to a 2021 X12™. 

Productivity Pays 

Having the right spec with a lighter engine pays big dividends, regardless of the business you are in or the type of vocational vehicles in your fleet. For instance: 

Refuse – A lighter engine with the proper spec can accelerate faster between stops and carry more waste, potentially resulting in greater coverage per vehicle on its daily routes. Depending on the size of the municipality being served, it could reduce both the number of vehicles and manpower needed for total coverage. It can also save money at landfills where there is a per-vehicle charge in addition to the cost of the waste being dumped. 

Mixers – The key is to spec the vehicle at maximum load, making sure that it adheres to local load limits for highways, bridges and roadways throughout the area. Some mixers have three drive axles, to help provide the traction needed to negotiate muddy, difficult worksites with steep inclines. 

Dump Trucks – Similar to mixers, construction dumps can have highly variable load weights and taxing work environments. For increased equipment longevity, operators should be trained in proper loading (between the axles with the initial loading, moving over the axles at the end). 

Bulk Haulers – Tractor trailers are a different configuration and have greater flexibility with regards to load distribution. The fifth wheel can be shifted forward to put more weight on the drive axle, or back to put greater load on the rear axles. When spec’ing the tractor, you can often choose a smaller displacement engine (such as a 12-liter rather than a 13-liter), which will allow for a shorter frame rail and wheelbase measured as BBC. The combined weight savings can be as much as 1,000 lbs. in the front end, and an equivalent increase in payload while staying under the 80,000-lb GVW limit. (The typical load pattern for a tractor trailer is 12K steer axle, 34K tandem axle and 34K trailer). 

Additional Considerations

When spec’ing a vocational vehicle, it is critical to take into consideration seasonal additions like a snowplow attachment, pumps, or any feature that requires an extended front bumper or puts extra weight on the drive axle. When spec’ing an engine for weight savings, it is critical to choose a horsepower/torque rating that meets the highest regular power demand in your duty cycle, and to pair it with an appropriate transmission, ensuring that you get the highest productivity, exceptional reliability and longevity plus driver-pleasing performance. All at a reduced powertrain weight. Cummins PowerSpec can guide you through the entire process
