Abstract
An interactive environment is supposed to be one of the most important technologies for developing teaching systems for a deck crew. It enables modeling different interworking scenarios (excursions) among marine crafts as well as responding maritime facilities to operator performance, etc. The ship crew is possible to be taught in order to know how to act effectively in alarm or challenging situations in such an environment. A virtual polygon can also be used as a decision making support system to forecast growing threats and then choose the best behavior strategy/policy. The paper illustrates the findings of a virtual polygon development for simulating navigation safety problems with Blender environment applied for a three-dimensional graphic image representation, Delphi programming language for software support of the developed methods and a user interface design. The authors explained a layout algorithm for constructing three-dimensional offshore surface vessels. Moreover, the researchers simulated various situations in different weather effects and wind and wave perturbation in their study.
Highlights
Virtual polygons established for navigation allow one to test prototypes of above-water crafts movements one to another, to other crafts, such as low-flyers, and the environment/ external conditions
Each situation listed in the simulation subsystem consists of offshore surface crafts models contained in the subsystem of graphic images, and a staged environment that included sea surfaces in different meteorological conditions and the presence / absence of different guided and unmanned crafts
A graphical user interface for modeling various situations mentioned in the Beaufort wind force scale is a form with thirteen buttons, an area for outputting a situational pattern, and an output field for a verbal definition of wind capacity, an average wind velocity, and a description of the wind effect in the main sea
Summary
Virtual polygons established for navigation allow one to test prototypes of above-water crafts movements one to another, to other crafts, such as low-flyers, and the environment/ external conditions. The paper notes that the critical technology for designing marine training systems is an interactive marine environment in virtual reality and online mode. The information about them is obtained from an Automatic Identification System (AIS) In this regard, the authors dwell on a number of additional practical problems arising in developing the architecture of the necessary software. The authors dwell on a number of additional practical problems arising in developing the architecture of the necessary software It is known from the paper [7] that simulators are used in education to imitate a ship engine operation in a virtual reality. It is important to point out that there is an opportunity to train the crew to act in such emergency situations that cannot be performed in real conditions according to safety requirements for precisely that reason for using simulators [9]
