Reductions in Energy Consumption and Emission of Harmful Exhaust Gases by Fishing Vessels

Abstract

This article presents an analysis of the influence of engine types, fuel types and selected methods of fuel treatment before injection on reductions in fuel consumption and exhaust emission components. This is the first of such studies, the continuation of which will allow a comprehensive assessment of the impact of cutter operations on environmental pollution. For the selected type of cutter, EEOIs (Energy Efficiency Operational Indicators) were determined to be a measure that takes into account both fuel consumption and harmful gas compound emissions depending on the type of engine used and the type of fuel. The data necessary to prepare this analysis were obtained during operational tests carried out on selected cutters with various types of engines fuelled with liquid fuel and a new catalytic fuel treatment method developed by the authors, while for the case of using gas fuel and a common rail engine, possible effects were forecasted. The effects of engine type, years of manufacture and fuel type (liquid and gas) on fuel consumption and emissions of selected exhaust components are demonstrated. The positive effects on fuel consumption and emissions of harmful exhaust constituents obtained, under laboratory test conditions, for an engine fuelled with catalytically treated fuel have allowed further research directions to be set for cutter engines equipped with injection equipment with applied catalytic coatings.

Enhancement of Maritime Sector Decarbonization through the Integration of Fishing Vessels into IMO Energy Efficiency Measures

“…Meanwhile, the IMO has several conventions that apply to the safety of fishing vessels, such as the 1995 STCW-F and the Torremolinos International Convention and its amendments of the 2012 Cape Town Agreement; the fishing sector does not have to comply with the IMO energy efficiency precepts, even if a part of the fleet exceeds the 400 and 5000 GT thresholds, with a propulsion power of up to 6000 kW, which could correspond to many small merchant or ferry vessels [29,30]. This sector of the maritime industry consumed 12.86 million tons of fuel during 2018 and emitted about 40.7 million tons of greenhouse gas emissions, which accounts for 4% of emissions of the maritime sector.…”
