Opis:
This paper concerns the application of bayesian network to planning and monitoring life saving actions at sea. The presented bayesian network was formed a.o. on the basis of the determined life raft safety function. The proposed bayesian network makes it possible to determine reliability of conducted life saving action, with accounting for a large number of events which influence course of the action. Reliability control was proposed to be applied to search and rescue - SAR action in contrast to risk control. Reliability levels were defined to make the assessing of safety of conducted SAR action, possible.

Opis:
The main components influencing the efficiency of rescue actions are: estimating the localization of an accident, estimating the survivor acting and error of its valuation, marking out the estimated survivors localization and an error of that localization, correct estimating a search are. The following elaboration presents the method of estimating the search and rescue area based on the search objects leeway speed regression model. There have been used a diffusion process (Fokker – Planck equation) during projecting a model to mark out a search probability area map.

towing resistance
Opis:
The paper presents the experimental and numerical investigations of a novel design of a pneumatic life raft in calm water conditions. Two main issues were considered: the life raft performance under tow and its resistance in calm water conditions. The experiment and CFD simulations were performed by using the full scale prototype to eliminate the scale effect. The towing tank tests confirmed the results of numerical computations. The compatibility of the results of numerical and experimental tests was high mainly because the new life raft does not deform under the hydrodynamic and aerodynamic loads. The characteristics similar to rigid body behaviour result mainly from a new construction and materials used for manufacturing the life raft.

Opis:
The paper presents the results of investigations on the life raft leeway induced by the fluctuations of wind direction. The surface current is one of the main factors determining the life raft leeway, but the recently conducted research confirmed that there are also other elements influencing the perturbations of leeway direction. The field experiments showed diversion of the life raft leeway from the downwind direction. This diversion can be explained by the existing cross wind component. The wind tunnel tests allowed to determine the aerodynamic coefficients in the fluid-state control system. On the basis of the test results the expression for the wind pressure force has been formulated. The mean deviation and median of probability distribution of the leeway diversions from the downwind direction has been determined on the basis of investigations conducted at sea. The models for the life raft velocity dependent on wind velocity, developed for the life raft with drogue and without drogue, are presented in the paper.
