 note = {In order to find the effect of aluminum alloy ship's bottom fouling on the speed performance and
fuel consumption, the fuel flow was measured when an aluminum alloy ship was navigating at a constant
speed. Also the speed test was conducted periodically. The results of the experiment are shown below.
1) According to the record when undocking for five years, the rate of ship speed reduction and that
of fuel consumption increase to the main engine power output were 0.1 to 1.4% and 0.1 to 3.3%
respectively and were nearly unchanged.
2) At the time of eleven months after undocking in 2006, the ship speed reduced by 0.6knot (4%) and
the fuel consumption increased by 2.7kg/nm (21%) when running at full ahead. At the time of eight
months after undocking in 2009, the ship speed reduced by 0.5knot (5%) at half ahead and reduced
by 0.7knot (5%) at full ahead. Meanwhile, the fuel consumption increased by 1.5kg/nm (25%) at half
ahead and increased by 2.7kg/nm (21%) at full ahead.
3) Due to docking, the ship speed increased by 1.0knot (9%) at half ahead and increased by 0.9knot (6%)
at full ahead, and also the fuel consumption reduced by 1.8kg/nm (24%) at half ahead and reduced
by 2.9kg/nm (18%) at full ahead. The simplified bottom cleaning made the ship speed increase
by 0.2knot (2%) at half ahead and increase by 0.4knot (3%) at full ahead, and also made the fuel
consumption reduce by 1.1kg/nm (15%) at half ahead and reduce by 1.5kg/nm (10%) at full ahead., 長崎大学水産学部研究報告, 93, pp.11-17; 2012},
