Accounting for cyber risks in the safety management of the operation of power equipment of a floating regasification plant
The requirements of the resolutions of the International Maritime Organization (IMO) provide for the need to organize the management of cyber risks in navigation safety management systems. The article presents technogenic risk as a criterion for assessing the level and ensuring safety, which is understood as a measure of possible hazards, simultaneously taking into account the frequency of occurrence of an undesirable event and the consequences of the implementation of an undesirable event. The results of the analysis of the operation of floating regasification units of liquefied natural gas, based on operational experience and collected statistical data, are presented. The model "tree of failures" is constructed, the resulting event in which is a gas leak. It is established that a "gas leak" can occur with a frequency of 0.4 1/year. The management subsystems of a shipping company that allow remote control and management of power plants and equipment are considered. The disadvantage of the systems is their vulnerability to cyber attacks. Based on the analysis of publications of the DNV classification society, eight main vulnerabilities in the field of cybersecurity of a floating regasification installation were identified. Based on the statistics of cyberattacks on the infrastructure of industrial enterprises of the Russian Federation in 2019, it was found that the frequency of cyberattacks on ship equipment will be approximately 0.009 1/year.
