Efficiency of procedures protecting vessel safety
Main types of threats of vessel safety have been considered: mistakes of ship experts, refusals of critical elements, failures of software of ship technical means. Some organizational means on minimization of consequences of these threats have been described. The assessment of reliability of vessel safety protection as probabilistic characteristics of a dangerous event has been proposed.

Technique of estimation of indeterminacy in plans of ship operations
The technique of evaluation of indeterminacy in developed plans for safe ship's key operations has been proposed. Regulations of informational processes theory as well as probabilistic methods and entropy approaches have been used for working out the technique. Some examples of its using have been given.
