ABS Knowledge in Ship Energy Efficiency Highlighted

The ABS Ship Energy Efficiency Measures Advisory was referenced in a Reuter’s article discussing the connection between the demand for transportation in the US and the demand for oil.

"The speed of a vessel has a dramatic impact on fuel consumption because the speed is related to the propulsive power required by approximately a third or fourth power relationship," according to the American Bureau of Shipping. "Roughly this means if you double the speed you increase the power required by a factor of at least 8."

"Likewise, sailing at 90 percent of the design speed requires only 75 percent of the power. The corresponding reduction in total fuel consumption is offset a bit by the longer time spent to complete the voyage. So by slowing down 10 percent the vessel can save about 20 percent in fuel".
