In this paper a stochastic model of tanker traffic is developed to determine the probability of vessel casualties resulting from the transit traffic through a narrow waterway. More specifically, the present study models the collision and grounding probabilities in a waterway resulting from course changes due to hydrodynamic forces acting on the vessel. The computation of vessel positions and th...

Design of ship control system has been great challenge since long time, because the dynamics of ship are not only nonlinear but change with operating conditions (de...

Absences attributed to sickness were investigated in 1410 deck and engine-room crew members during a period of two years and five months. The mean frequency of absences was 0-23 per man year, with a mean duration per absence of 41 days. The absence frequency varied with both rank and place of work. Altogether 23% of deck officers serving throughout the study and 43% of engine-room ratings had o...

UNLABELLED Currently, the bacterial composition of raw milk in tanker trucks and the outcomes of transfer and storage of that milk at commercial processing facilities are not well understood. We set out to identify the bacteria in raw milk collected for large-scale dairy product manufacturing. Raw bovine milk samples from 899 tanker trucks arriving at two dairy processors in San Joaquin Valley ...

In this paper, the variants of fender protection traditional port tugs and possibility using on unmanned vessels such type are considered; main elements investigated. At present, technical level mechanisms, instruments software allows creating crewless vessels. One promising directions in development is tugs, since having relatively large river sea they perform production tasks water area appro...
