Figure 14: Estimated Current Fuel Consumption for SESSF Vessels Surveyed and Fuel Consumption after Adopting Engineering Solutions
From these recommendations, the estimated reduction of fuel use per year for each vessel was calculated and is summarised in Figure 13 and Figure 14 respectively.
6. CONCLUSIONS
The project was able to successfully estimate the fuel consumption of southern rock-lobster fishing and south- eastern shark and scalefish long-line fishing vessels operating within Tasmanian waters. The amount of fuel consumed by southern rock-lobster and SESSF vessels can be reduced by the adoption of the following engineering solutions:
Reduction of vessel speed during steaming to fishing grounds to between 6.5 and 7 knots for southern rock-lobster vessels, and 6.5 and 8 knots for south-eastern shark and scalefish vessels.
Replacement of bilge keels with retractable passive stabiliser fins.
Replacement of flat-plate rudder section with a NACA foil section.
Replacement of keel cooling with heat exchanger if vessel uses deep-water port.
If replacement of keel cooling is not possible, then run keel-cooling pipes as part of the bilge- keel structure to reduce appendage drag.
