WHEN IS COLLISION UNAVOIDABLE?
The motions of a large super tanker in response to various maneuvering commands is computed using the nonlinear hydrodynamic coefficients presented by van Berlekom and Goddard. The results of the simulations were analyzed to determine the critical range (the range at which collision is unavoidable) and the simple maneuvers necessary to minimize this range. The study shows that the critical range depends strongly on the two ships' headings and speeds, and on the permissible maneuvers. The effect of design features, such as rudder size and radar accuracy does not appear very significant. The effect of operating procedures such as "Rules of the Road" or the "Right Turn Rule" does seem significant.
