Risk Analysis of Dynamic Positioning Systems based on Incident Data

Dynamic positioning (DP) systems have been an excellent solution for maintaining positions of vessels and heading them in the offshore industries. Many researchers have developed different methods manage the risks related with DP systems. Evidence has shown that the occurrences of position losses of DP vessels are not seldom. This paper the focuses on risk analysis of different DP systems in different applications and uses the statistical methods to estimate DP failure probabilities based on incident data collected by International Marine Contractors Association during 2010-2018. Regression analysis and correlation analysis are conducted for quantifying the risks from different causes, as well as identifying the significant causes and relationships between main- and secondary causes. At the end, the paper also presents some general suggestions for safe operations of DP systems in different applications.
