Tematy:: weather routing
isochrones method
Opis:: The paper is focused on adaptation of an isochrones method necessary for application to a weather routing system with evolutionary approach. Authors propose an adaptation of the isochrones method with area partitioning assuring that the route found by the adopted method would not cross land. In result, when applied to a weather routing system with evolutionary approach, this proposal facilitates creation of initial population, resulting with routes of reduced collision risk and low costs of passage.

Opis:: The article presents some safety-related problems of the computer control systems and overall automation. The development of automation and information technology in recent years has forced to develop a number of new technologies and solutions for advanced process control and other technical installations. It seeks for automation of complex technical installations, conceived as means of controlling all subsystems and devices automatically, without human intervention. However, if we consider the economic aspects, the maintenancefree concept is not justified. The partial automation of selected systems is also of interest. This work considers some general aspects of control system design with emphasis on safety aspects. As an example of the protection system, the installation of diesel engine oil lubrication is presented.

Tytuł:: Non-linear backstepping ship course controller
Autorzy:: Witkowska, A.

Data publikacji:: 2007

Tematy:: backstepping
Lapunov function
asymptotic stability
Opis:: A ship, as an object for course control, is characterised by a nonlinear function describing the static manoeuvring characteristics. One of the methods, which can be used, for designing a non-linear course controller for ships is the backstepping method. It was used here for designing the configurations of non-linear controllers, which were then applied for ship course control. The parameters of the obtained non-linear control structures were tuned to optimise the operation of the control system. The optimisation was performed using genetic algorithms. The quality of operation of the designed control algorithms was checked in simulation tests performed on the mathematical model of the tanker completed by steering gear.

Opis:: The paper is concerned with the problem of safe trajectory planning for approaching during emergency STS (Ship to Ship) transfer operation with oil spill. The safe trajectory means that the way points does not cross in the area of the environment with the static and dynamic obstacles and at the same time satisfies ship's stopping and speed deceleration performance. The evolutionary path planning algorithm is used to determine trajectory designed as way points and straight line segments between them. The way points - ship positions and velocity can be treated as reference value to support navigator in decision making during Approach Manoeuvre and to mitigate the risk of collision which mostly results from exceed velocity of approaching. The task of trajectory planning is defined as constant optimization process to minimize trajectory length, course alteration and maximize safety in a navigational environment. This paper examines exemplary navigational scenario based on emergency STS accident.
