Learn about our rigorous Cummins Onan marine generator testing

0
comments

To make it to final production, marine generators from Cummins Onan have to go through a series of exacting design steps and tests. This robust process is described in a new flyer available on our website.

Cummins Onan engineers start with analysis-led design (ALD) techniques to model generator components. With the designs optimized in a 3D CAD system, prototype units are built and then extensively tested.

Some tests take place in our new acoustical testing center, or ATC, on our Fridley, Minnesota campus. The ATC, the largest engine-testing facility of its kind in the world, enables Cummins engineers to precisely measure the sound output of generators, including with binaural recording to mimic human hearing.  Other tests, critical to understanding and reducing generator vibration, are conducted on shake tables.

All these design and testing steps are detailed in a new flyer that you can download here

Partnering on the voyage of The Greatest Loop: Cummins Onan and Beneteau Powerboats

0
comments

We are proud to be one of the partners helping Beneteau Powerboats outfit a Swift Trawler 34 for the voyage around the Great Loop, the popular circumnavigation route of the Eastern U.S. The boat, named The Greatest Loop, will make the passage starting May 15, 2012, from Annapolis, Maryland, and return in September 2012.

The trip is designed to show the seaworthiness and comfort of Beneteau Powerboats in particular and promote the cruising lifestyle in general. We are supplying a 7.5 kW MDKBJ marine generator, rated at 1100 amps and converted to run at 60 Hz. The generator will power all the appliances, controls and other electrical loads on the boat.

This Quiet Diesel model has the highest power density of any housed set in the Cummins Onan product line. Based on wattage at full load and the volume of the generator, the unit delivers 26% more power per unit volume compared to competitive generators. This advantage in power density extends to other models as well. For example, even compared with larger 7 kW 50 Hz generators from other manufacturers, the Cummins Onan 6 kW 50 Hz delivers 24% more power per generator volume. By offering more power in a smaller package, designers and boat owners have more space available for other necessities and amenities.

Cummins Onan marine generators are exceptionally quiet with minimal vibration. Plus they are extremely robust and backed by the world’s largest global support network. Beneteau has chosen to equip both its sailboats and powerboats with Cummins Onan generators. The Greatest Loop also uses a Cummins Marine engine.

As described by the America’s Great Loop Cruisers’ Association (AGLCA), the Great Loop is the “continuous waterway that encompasses the eastern portion of North America including the Atlantic and Gulf Intracoastal Waterways, the Great Lakes, the Canadian Heritage Canals, and the inland rivers of America’s heartland.” The entire route can range from 5,000 to 7,500 miles, depending on the particular options chosen. Most Great Loopers make the passage counterclockwise, to take advantage of favorable river currents. The most popular kind of boat used for the trip is a recreational trawler, such as Beneteau’s The Greatest Loop.

According to Beneteau, the Swift Trawler 34 is a performance-based cruising boat offering exceptional fuel efficiency, stability and maneuverability. With a very sea-worthy hull, and plenty of living space, the Swift Trawler 34 is designed for the ocean and life at anchor. Its size and clever features make the Swift Trawler 34 very easy to handle, solo or as a couple.

The Greatest Loop, hull 202, was built at one of Beneteau’s trawler factories in Challans, France, and arrived in the U.S. on March 23, 2012. She is currently being outfitted with the latest equipment supplied by Beneteau partners Cummins, Cummins Onan, Raymarine and Dometic Marine. Other industry partners lending support for the journey include America’s Great Loop Cruisers’ Association, MarinaLife, SGB Finance and Annapolis Yacht Sales, in addition to other Beneteau dealers around the country.

Beneteau is known worldwide for its sleek design, quality construction and innovation in the manufacturing of seaworthy sailing and power yachts. The Beneteau company began more than 125 years ago when Benjamin Bénéteau started building fishing trawlers in Saint-Gilles-Croix-de-Vie, France. Today, the company continues under the leadership of Benjamin Bénéteau’s granddaughter, Madame Annette-Bénéteau Roux. Beneteau has grown to twenty manufacturing facilities in France, Italy and the United States. Another production facility for powerboats is about to start operations in Brazil.

Marine publications throughout North America and Europe will be aboard The Greatest Loop for specific segments of the journey to document and share their experience with their readers. Or if you’re interested in following her journey yourself, you can participate in the expedition at The Greatest Loop Website or The Greatest Loop Facebook page.

Besides supplying the generator, we’ll be participating in events and gatherings along the route, as well as monitoring the performance of our Quiet Diesel generator. More information on the 7.5 kW generator and our role in the voyage is available at now.cumminspower.com/beneteau/.

But be sure to also keep an eye out for more blog posts from us that will keep you updated as the adventure gets underway as well as all along the way. We can’t wait to cast off!

comments

With operations in paint, hydraulics, lubricants and power generation, FT Farfan is a large business in Trinidad and Tobago that serves customers in the energy, petrochemical, industrial, agricultural and woodworking industries. The company recently added another line of business: a distributorship for Cummins Onan with a focus on the marine generator market.

There are significant opportunities in selling and servicing marine generators to commercial fishing vessels, especially in repower, or the replacing of existing onboard generators. Recently, with orders growing at a rapid pace, our goal was to help FT Farfan increase their technical expertise and service capabilities as quickly as possible.

Accordingly, two FR Farfan sales engineers attended extensive Cummins Onan training. With the help of Juan Hernandez, the Cummins Onan Caribbean Territory Manager, and our distribution development team, the sales engineers were able to easily get up to speed on our line of marine generators and installation procedures.

Juan Hernandez said, “We are enhancing our distributor capabilities, which are critical for us to grow our marine business in the Caribbean region. Through training sessions such as this one with FT Farfan, we strive to provide our customers with the right products and quality services.”

The Miami Boat Show, held February 16–20, was a very successful event for Cummins Onan on two key fronts—connecting with industry partners and connecting with customers.

Many of our OEM boat-building partners were on hand, including Brunswick, Sea Ray, Hatteras, Sunseeker, Beneteau, Riviera and Ferretti. This provided a great opportunity to together explore new opportunities and further strengthen relationships. It was exciting to see the new models our partners had on display and the interest they generated among buyers. Riviera, an Australian company, reported record sales during the show.

Cummins Onan enjoyed a great booth location and attracted plenty of traffic, with engineers and naval architects particularly well represented. The staff from dozens of Cummins Onan dealers welcomed many interested buyers from around the world, including attendees from Asia-Pacific as well as Central and Latin America.

Barry Stamm, Marine Sales Manager at Cummins Power South, was especially pleased with the strong sales in the booth, prompted in part by special pricing in effect for the show. He observed that a majority of customer inquiries at the show concerned repowers, replacing existing engines and generators. In addition, our knowledgeable application and service engineers expertly addressed a wide array of both technical and service questions from booth visitors.

Our many thanks to all of you who visited our booth and to all those who made the 2012 show such a success. See you in 2013!

Cummins Onan at METS: record attendance, busy booth, well-received seminars

0
comments

The Marine Equipment Trade Show, or METS, was held in Amsterdam November 15–17, and it broke last year’s attendance record by 2%. Cummins Onan participated in this largest trade show for boats and marine equipment. We hosted lots of activity in our booth and had a good turnout for our two seminars on the important topic of reducing vibration in marine generators.

Vibration has long been one of the key issues challenging the marine industry. Cummins Onan has relentlessly devoted decades of design and optimization to manufacture the quietest generator sets with the least vibration. Both of our seminars on reducing vibration — one basic and one advanced — were led by Steve Seidlitz, a senior technical advisor at Cummins Power Generation with 39 years of industry experience. Steve is an expert in mechanical dynamics related to vibration control.

The basic seminar dealt with fundamental concepts and terms, covering these topics:

• Why We Care About Excessive Vibration
• Mechanical Dynamics
• Frequency Domain and Why Working in It Is Very Important
• Resonances
• Engine Order and Excitation
• Place to Go for Continuing Education

The advanced seminar delved into the following:

• Mounting System Design
• Importance of the Generator Set’s Supporting Structure
• Taking Vibration Measurements
• What These Measurements Tell Us
• The Problem with Using Overall Vibration Levels

Steve will be using information he presented in the seminars as the basis for a white paper on vibration that will be published in 2012. We’ll let you know when it’s available, so stay tuned!
