Cruise ship Mount Washington, resumes service this month after her annual winter lay-up in frozen Lake Winnipesaukee, New Hampshire, but this season the old lady will be powered by a pair of newly installed forward-looking Caterpillar C32 ACERT marine diesel engines when she leaves home port Weirs Beach.

– Propulsion

The majestic Mount Washington, launched way back in the early days of WWll is of 230 ft LOA (lengthened by 24 feet in 1982) with a 1250 passenger-capacity for daily excursion cruises to five different ports of call around the picturesque, unspoiled lake. She was originally propelled (until stripped of machinery appropriated by the U.S, Government for war use) by two Herreshoff Manufacturing Corporation 3-cylinder triple-expansion engines powered by steam from oil-fired water-tube boilers.

Subsequently, in 1946, a re-engined Mount Washington was served reliably for an incredible 64 years (itself a tribute to the engine builders) by a pair of 8-cylinder 615 bhp Enterprise DMG18 marine diesel engines. Perhaps of necessity, the owners decided last year that the time had come to replace them with an EPA Tier ll emission-compliant power plant.

Cat C32 ACERT Diesel Engines

The type of marine diesel engine chosen was the  C32 ACERT model, manufactured at Caterpillar’s state-of-the-art ‘Marine Center of Excellence’ facility in Greenville, South Carolina.  The pair of Vee-type, 12-cylinder, four-stroke engines, deliver 750 bhp (559 kW) each at 1800 rpm, with a mechanically actuated, electronically controlled unit injection (MEUI) fuel system. These Cat engines are also equipped with the ADEM A4 electronic control unit, and responsive twin turbocharging with after-cooling.

Benefits, claim Caterpillar, will be a decline in fuel consumption, particularly at part load, and a reduction in smoke and emissions, while delivering reliable maximum power output. C32 ACERT engines comply with IMO and EU inland waterway regulations, as well, of course, those EPA Tier II limits which are relevant to the operation.

Mount Washington, whose detailed history manifests many examples of the American pioneering spirit, now continues her odyssey on Lake Winnipesaukee powered by technically advanced diesel engines that will drastically reduce exhaust gas emmissions and ensure that this unique cruise experience be there for the next generation of vacationers.
