M/S Mount Washington Repower Project

In October of 2009, Winnipesaukee Flagship Corporation undertook a project to repower the excursion vessel Mt. Washington, with funding from EPA 2009 DERA.  The old engines in the Mt. Washington were two 1946 Enterprise DMG-18s, each producing 615 HP.  The Enterprise engines were pre-regulation EPA Tier 0 engines, and emitted much more NOx and PM than their contemporary equivalents.  This repower achieved the goal of reducing pollutant emissions in three steps: lower emitting engine technologies, more efficient fuel combustion, and installation of diesel exhaust aftertreatment.

M.J. Bradley & Associates assisted the Winnipesaukee Flagship Corporation during the bid evaluation process, and the decision was made to install two 2010 CAT C32s, each producing 750 HP.  The new CAT engines are EPA Tier 2 Marine compliant, and significantly quieter than the old engines, a topic of frequent complaint from Lake Winnipesaukee residents.  MJB&A provided support to this project from start to finish, including grant funding procurement, competitive technology procurement, installation and finally, technical and financial reporting to NESCAUM.  This project was completed in May 2010, and is achieving annual emissions reductions of 7.36 tpy NOx and 0.3 tpy PM.  With a total project cost of $600,000, these reductions are being achieved at a lifetime cost of $9,000/ton NOx and $220,000/ton PM.
