THE POSSIBILITIES OF SIMULATION RESEARCH OF THE RISK ASSESSMENT OF LNG TANKER MANOEUVRING IN THE SELECTED AREA
Abstract
The article presents the genesis of safety assessment of LNG tankers, along with safety criteria. The utilitarian need to carry out simulation research risk assessment in respect of a LNG carrier manoeuvring in restricted areas has been justified . As a standard vessel an oil tanker has been assumed meeting the authorisation requirements of the the selected LNG terminal. The shipпїЅs operational conditions have been identified and correlated with the manoeuvres in the terminalпїЅs area. The mathematical models of basic manoeuvres have been built taking into account their execution by admitted to the research ship depending on the possible types of propulsion systems that meet the ecological requirements of navigational zone. In the mathematical description the characteristics of the geometry of the hull (the length over all, breadth, draught) and vessel movement parameters in hydro-meteorological conditions have been taken into account. Diagnosis has been provided for and the mathematical description has been made in respect of the critical manoeuvres in relation to the ship navigationпїЅs safety on the fairway and terminalпїЅs areas. The initial conditions and boundaries have been determined. Simulation studies can be conducted with the use of the software based on dynamic modelling of the designed system as assumed for the purpose of research. Studies can be located in the areas and fairways not technically verified so far.. The opportunities have been presented to conduct research using different methods of risk assessment.
