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.

Given the diverse stakeholders in the maritime industry, it is understandable that collaboration is a challenge. However, the interconnected ecosystem of maritime makes collaboration essential. From ship owners and operators to port authorities, from shippers to shipbuilders, from classification societies to marine service providers and others, there are vast opportunities to work together and cooperate. To gain insight, we asked our Expert Panel Roundtable: How can the maritime industry increase collaboration, and what are the benefits?

More than almost any trend, decarbonisation is driving the future of maritime. That reality alone makes decarbonisation the perfect topic for our first-ever Expert Panel Roundtable column. Traditional maritime fuels, like heavy fuel oil, release harmful pollutants that contribute to air pollution and have adverse health effects. We have to do better, and discussions in the maritime industry centre on which combination of alternative fuels and other technologies can solve the shorter- and longer-term challenges of decarbonisation. For an update on the various approaches, we asked our Expert Panel Roundtable: What are the latest maritime technology trends in decarbonisation?
