Cummins Inc, a leading manufacturer of diesel engines for the commercial marine industry, will feature one of the most impressive engine line-ups at Nor-Shipping (Oslo, Norway; June 4-7) with a “smallest-to-largest” commercial marine engine display featuring the QSB7 at 132 hp (98 kW) and the QSK95 up to 4,200 hp (2983 kW).
The 6.7-liter and 95-liter engines highlight the extension of Cummins commercial marine power at both the low and high ends of the range.
“We are excited to offer an expanded range of power options from our smallest 6.7 liter product all the way up to our largest 95 liter product – a benefit for our offshore and commercial transport customers operating in the North Sea and globally,” says Rachel Bridges – Marine Regional Leader, Europe and Middle East.
With prime power ratings from 98 to 210 kW, the QSB7-DM is ideal for ship’s service and emergency genset power. All ratings are I MO Tier II and EPA Tier 3 certified, plus 50 Hz ratings feature EU Stage Ilia non-road certification. The QSB7 utilizes advanced combustion technology to reduce emissions in-cylinder without the need for aftertreatment. Plus, the engine has been certified by globally-recognized marine classification societies, including American Bureau of Shipping (ABS), Bureau Veritas (BV), Det Norske Veritas (DNV), Germanischer Lloyd (GL) and Lloyd’s Register (LR). It was designed to meet Safety of Life at Sea (SOLAS) and multi-engine Unmanned Machinery Space (UMS) requirements.
The QSK95 offers flexibility in power configurations for propulsion: auxiliary, genset and diesel electric applications. With ratings from 1,864 to 2,983 kW (2,500 to 4,200 hp), the QSK95 is ideal for high-hour, hardworking vessels such as tugs, inland waterway towboats, offshore support vessels, passenger transport, dredges, short sea cargo and coastal tankers.
The QSK95 provides a power output previously exclusive to medium-speed marine engines with the advantage of a lower capital cost, a more compact installation and exceptional fuel efficiency. The engine was designed to achieve IMO Tier III and EPA Tier 4 emissions using Cummins own SCR clean exhaust aftertreatment, a uniquely integrated solution offering more efficient packaging and reduced space constraints.
Despite the difference in size and output between the QSB7 and the QSK95, the two engines share a similar Cummins electronic control system, bringing the benefit of diagnostic commonality supported by a worldwide service network.
