Cummins - Experts & Thought Leaders

Cummins has extended its portfolio of Onan marine generator sets with the introduction of the MDC (Marine Diesel Cummins) Turbo and Onan QSB7E ranges. Details of the two generator sets will be on display at the Marine Equipment Trade Show (METS), a premium European showcase for professionals in the leisure marine industry. MDC Turbo and Onan QSB7E The arrival of the MDC Turbo and Onan QSB7E means boatbuilders and owners can deal with a single trusted brand – Cummins – for the entire power requirement of their vessel. Cummins is the parent brand of Onan and Stamford, a major name in alternators for marine applications. The electrical power spread of the Cummins marine Onan range stretches from 4 kWe to 195 kWe. Previously, the highest Cummins Onan rating available was 65 kWe. Cummins generator sets are renowned for their robust build quality and outstanding performance characteristics, notably in the area of low noise, vibration, and harshness (NVH). Smooth and efficient power delivery The versatility of the MDC and Onan QSB7E is enhanced by the ability to synchronise the generator sets The two new ranges, which can run on 100% hydrotreated vegetable oil (HVO 100), build on that proud heritage of reliable, smooth, and efficient power delivery. The versatility of the MDC and Onan QSB7E is enhanced by the ability to synchronise the generator sets, yielding benefits such as improved stability of electrical supply, greater fuel efficiency, and higher levels of comfort all around for passengers and crew. MDC genset Cédric Merveillaud, Cummins Director of Marine Europe, said, “With the one supplier for propulsion and auxiliary power, life becomes a lot simpler and more productive for boat builders and owners. Cummins can handle the entire power demand.” The MDC genset complies with EPA Tier 3 and EU Stage V regulations and is available for both commercial and recreational marine applications as a 50 Hz or 60 Hz model. It can also be specified as either non-aftercooled or aftercooled. This provides two power outputs, giving the genset a rating of 40 to 80 kWe and 80 to 110 kWe respectively. User-friendly diagnostics Using the Cummins Onan Digital Display, the MDC provides user-friendly diagnostics including extensive engine and alternator information, ensuring customer ease on the water. At the top end of the Cummins Onan genset scale now sits the Onan QSB7E, a perfect low-noise power solution for a variety of maritime applications including high-end superyachts, small passenger ferries, fishing boats, and offshore support vessels. Available as unclassed, class-ready, and full-class, the Onan QSB7E has 10 power nodes and can be specified with an open or enclosed unit in both 50 and 60 Hz models. Maximum output is up to 195 kWe. Single-side service access MDC and Onan QSB7E have single-side service access and the water-cooled exhaust can be installed Like the MDC, the Onan QSB7E can be supplied with the additional option of a front-mounted power take-off which can be used to power various auxiliary systems, for example, hydraulic pumps, giving the customer flexibility and redundancy onboard. For ease of maintenance and maximum use of space, the MDC and Onan QSB7E have single-side service access and the water-cooled exhaust can be installed either in a forward or rear-facing configuration. At the base of both generators are multiple outlets for fuel and battery cables. Reliability, performance, and durability “Cummins marine genset products are designed and built to provide reliability, performance, and durability at reduced noise and vibration levels,” said Merveillaud. “That’s why this complete marine generator set package is ideal for recreational and light commercial vessels." “The 99kW commercial genset node is very popular in certain markets, and we expect the B4.5 genset package with a Cummins Stamford alternator will be an obvious choice when selecting power for operators for years to come.” The MDC and Onan QSB7E gensets are backed by Cummins’ extensive warranty (five years / 2,000 hours), and users have access to a worldwide service network of more than 10,000 authorised dealer locations, the largest such network in the world. Cummins B4.5 packs a propulsion punch The light but power-dense B4.5 is compliant with IMO II, EU Stage V, and RCD 2 regulations without the use of after-treatment. It offers a power range of 102-250 hp in propulsion format (76-186 kW) and 76-129 kWm in auxiliary format. Due to its optimised turbos, the B4.5 has best-in-class peak torque, which not only provides greater acceleration but makes it easier to maintain speed, even for vessels with high loads such as dredgers and fishing boats. Cost savings The high-pressure common rail fuel system of the B4.5 delivers class-pioneering fuel consumption The high-pressure common rail fuel system of the B4.5 delivers class-pioneering fuel consumption while its cast water-cooled exhaust manifold makes for lower surface temperatures and improved overall performance. The air intake system includes commercial and recreational reusable washable air cleaners for more cost savings. Remote backup throttle option The electrical system is offered in both 12 and 24 volts with simple electrical OEM interface connections that can be integrated with Cummins’ C Command Systems.

Beneteau unveiled its Cummins-powered SWIFT Trawler 54 at the Cannes Boat Show. The latest sleek and sophisticated addition to the Swift Trawler range, which now includes five models ranging from 35 to 62 feet, is designed for leisurely long-range cruising in a serene environment laden with new technology and home comforts. It is a statement of seafaring luxury from Beneteau, the marine brand, which has been working in partnership with Cummins for almost 20 years. The Swift Trawler 54 (17.13m) is powered by two Cummins QSB 6.7 engines each delivering 550hp. The QSB 6.7 is a proven winner for Beneteau, featuring on the Swift Trawler 48 (2 x 425hp versions) and Swift Trawler 35 (single 425hp). Twin Cummins engines With the refined power of the twin Cummins engines, the Swift Trawler 54 has a cruising speed of 8 -12 knots and a maximum speed of 20 knots. It offers a range of 700 nautical miles at nine knots, maintaining a 10% fuel reserve. Handling is enhanced by the ‘Fusion’ hull shape from the drawing board of Dixon Yacht Design. “The QSB 6.7 550hp has excellent power density and gives Beneteau the right balance of power, fuel efficiency and smoothness, with low levels of noise and vibration,” said Patrick Leroux, Recreational Marine Sales Manager at Cummins France, based in Nantes, not far from Beneteau’s manufacturing base. Alternative pod system “It is also equipped with Cummins’ world-beating DockCommand® controlled docking system that integrates engines, transmission and the bow and stern thrusters through a highly responsive joystick, which is easy to use.” The Swift Trawler 54 can accommodate up to six people, with an option for an additional crew berth Aside from the obvious benefit of greater manoeuvrability for the boat around marinas, the Cummins DockCommand® inboard joystick is easier and less expensive to maintain than the alternative pod system. It is suitable for any 35-60ft fibreglass recreational single or twin-engine boat. The Swift Trawler 54 can accommodate up to six people, with an option for an additional crew berth. The living spaces are spacious and bright, thanks to panoramic glazing offering a 360-degree view, and a staircase connects the flybridge to the wheelhouse. Integrated tender supports At the stern there is a 400kg tender lift, ample storage for kayaks and paddleboards and a hydraulic swim platform with integrated tender supports. The foredeck can be used as a sun lounger or open space with table, also incorporating storage for mooring lines and fenders. Beneteau’s ‘Silent Boat’ option allows for up to 10 hours of on-anchor autonomy without the need to run the generator, with a bank of solar panels topping up the lithium battery bank. “The Swift 54 is the most sophisticated boat that I’ve had the pleasure to be involved with in my time working with Beneteau, which goes back to 2006 when I was working for Cummins MerCruiser Diesel Europe,” said Patrick Leroux. Recreational marine world “After 140 years as a business, Beneteau is still a family-owned group, and it has been wonderful to watch them become such a powerful and respected name in the recreational marine world. They have an exceptional portfolio of motorboats, sailing boats and catamarans, ranging from six to 24 metres.” Patrick said a key aspect of the Cummins-Beneteau relationship was the presence of a global aftersales network, especially as the appeal of the boats and the customer base becomes more international. “For a prestigious brand like Beneteau, service is incredibly important. When we started out, I would say about 90% of Beneteau’s sales were to customers in Europe. Today, specialist support in all the major world markets – Europe, the United States, China – is fundamental, and that’s what Cummins can offer through our network of authorised dealers.” Global aftersales network Innovation has been the driving force at Beneteau for 140 years, said Beneteau brand director Jean-François Lair, adding: “The Swift Trawler 54 brings to life our vision of ‘rediscover the journey’, where you enjoy the journey as much as the destination.” “Supremely elegant and integrating cutting-edge technologies, the Swift Trawler 54 brings the comfort on board to another level; in essence, it is everything our customers expect from a Beneteau.”
