Detection and Reduction of Fuel Consumption in Fishing Vessels
Journal Title: Turkish Journal of Maritime and Marine Sciences - Year 2018, Vol 4, Issue 1
Abstract
Subject of fuel consumption and savings in fishing vessels which is extensively studied in the international arena also have great importance for Turkish fisheries. With the widespread use of motorized fishing vessels, it is realized that fuel costs could reach up to 50% of total fishing costs and could threaten economic sustainability of fishing industry. This study reviews up to date influential fuel-saving factors in terms of operational and technical modifications, and suggests potential improvements to increase energy efficiency in fishing vessels. The most important factors in the operational area are seen as: Energy audit, flowmeter installation, reduction of cruising and trawling speeds, periodical maintenance, and savings up to %50 are achieved. In terms of technical modifications: Choosing the appropriate engine, gearbox and propeller, improving hydrodynamic structure of vessel, and reduction of drag force through modernisation of fishing gears appear as changes made in the first plan, and savings up to %40 are achieved. Although changes for energy saving requires initial investment cost, it will contribute to economic sustainability and ecosystem-friendliness of fishing activities in the long term.
