ABSTRACT- The evaluated project is to develop a commercially viable diesel-electric propulsion system suitable for medium sized (20 m) fishing vessels. Diesel fuel combustion dominates energy and air emissions in the life cycle of fishery products, and is an important parameter in a sustainable fishery. The current evaluation provided an initial estimate of diesel fuel consumption and greenhouse gas emissions versus a defined technology baseline for Newfoundland vessels, and showed a potential reduction of more than 30%. The basic strategy is to replace the single large diesel propulsion engine with electric motors and split the power production to several smaller diesel generators. A diesel engine operates within fixed power and torque curves with clearly defined optimum engine speeds; however, fishing vessels have various distinct modes of operation, each requiring differing power requirements. These include in port operations, steaming, trawling, and fixed gear. Alternatively, electric motors are designed to be highly efficient over a wide range of operational speed and power outputs; the vessel can operate through the whole range of operations by selecting the optimum number of generators for the load. Ancillary benefits include space savings, boat design flexibility, quieter operation and redundancy. Located in Newfoundland, the project is funded by the Technology Early Action Measures (TEAM), a Government of Canada Climate Change Action Fund initiative that acts as a catalyst for the development of greenhouse gas reduction technologies. The System of Measurement And Reporting for Technologies (SMART) is TEAM's greenhouse gas measurement protocol and is consistent with the draft ISO 14064 - Greenhouse gases - Part 2: Specification for the quantification, monitoring and reporting of project emission reductions and removal enhancements. This method is essentially a modified life cycle assessment for energy and air emissions. The greenhouse gas measurement study of the fishing boat project provided one of the first tangible executions worldwide of the draft ISO standard. Specifically, the study showed that the SMART protocol is consistent with the ISO standard, that a 3rd Party validation is practicable, that project and baseline procedures can be developed, and that monitoring and quantification methodologies and procedures are satisfied.
