Abstract:

Shiptrack occurrence is restricted to a narrow range of environmental conditions and ship operating characteristics. Under environmental conditions favorable for shiptrack formation, not all vessels produce a track. Shiptrack producing diesel vessels are distinguished from non-shiptrack producing diesel vessels by a 17.7 percent higher rate of fuel use, 8.8 percent larger power plant size, and one knot higher transit speed. T-tests comparing these two populations indicate that powertransit speed, powerfuelspeed, powerfuel, tonnagefuel use, powerhull cross-section, transit speed, power plant size and rate of fuel use are tactically distinct greater than 60 confidence level. These parameters and ratios of parameters may be useful in predicting the occurrence and non-occurrence of shiptracks.
