b'MEMBER NEWSEBDG-Designed Hybrid-Electric Ferry for Casco Bay Lines Enters ConstructionE lliott Bay Design Group (EBDG) an-nounced their design of a hybrid-elec-tricpassengervehicleferryforCasco Bay Lines of Portland, Maine will enter the construction phase. Both EBDG and Casco Bay Lines are PVA members. The 164-foot ferrywillreplaceanexistingdiesel-powered ferry, the Machigonne II, resulting in a reduc-tion of 800 tons of carbon dioxide each year, helping to improve air quality in and around Portland, Maine.EBDG has supported Casco Bay Lines and their steering committee since 2018 as they prepared and planned for this replacement ferry, operating between Portland and Peaks Island, Maine. The contract design meets op-erationalrequirements,increasedpassenger demand,andCascoBayLinesgoalofre-ducing their carbon footprint. As part of the preliminary design efforts, EBDG prepared apropulsionselectionstudytocompare various propulsion systems based on capital cost,operatingcost,reliability,serviceabil-ity,CO 2 emissions,andinportnoiseand exhaust generation.TheresultisaferrythatfeaturesABB Marine&Portshybridpropulsionsystem supportingdiesel-electricandzero-emis-sionsbattery-poweredmodes,aswellasa combination of both.
