It is important for every DP professional to understand the system well that they are going operate or maintain. Keeping this in view, this book starts with an introduction to the functioning of DP system. Chapter two makes the reader aware of the six degrees of the movements. The understanding of the movements controlled by the DP system and the movements compensated for offsetting the readings of the position reference sensors is explained. Chapter three deals with the seven components of the DP system, how they connect with each other and how the controller controls the thruster output with the help of thruster allocation logic. Asking questions make the learning process more interactive. The book includes the questions and their answers which address various aspects of Bloom’s taxonomy of understanding, applying and evaluating the subject. Chapter four to chapter fifteen contain the questions and answers. These chapters include questions and answers from basic functioning of the DP system, the sensor, position reference sensor, test on PRS, automation and networking used in DP system, various tests and trials conducted and importantly the operations related questions.

This is a report on the use of dynamically positioned vessels rather than mobile drilling units which is becoming more prevalent for intervention and maintenance of subsea wells. Recently the range of vessels being considered to perform this work has expanded to include diving vessels, ice breakers, ROV support vessels and other specialized vessels in order to minimize costs. The latter types may not have the equivalent dynamic positioning capability or level of redundancy associated with the classes of intervention vessels originally considered for use. This trend towards lower costs coupled with new applications of technology may also introduce other low cost vessels into the market such as supply vessels.

This book proposes a new approach to dynamic and online risk assessment of automated and autonomous marine systems, taking into account different environmental and operational conditions. The book presents lessons learnt from dynamic positioning incidents and accidents, and discusses the challenges of risk assessment of complex systems. The book begins by introducing dynamic and online risk assessment, before presenting automated and autonomous marine systems, as well as numerous dynamic positioning incidents. It then discusses human interactions with technology and explores how to quantify human error. Dynamic probabilistic risk assessment and online risk assessment are both considered fully, including case studies with the application of assisting operators in decision making in emergency situations. Finally, areas for future research are suggested. This practical volume offers tools and methodologies to help operators make better decisions and improve the safety of automated and autonomous marine systems. It provides a guideline for researchers and practitioners to perform dynamic probabilistic and online risk assessment, which also should be applicable to other complex systems outside the marine and maritime domain, such as nuclear power plants, chemical processes, autonomous transport systems, and space shuttles.

Current technological advancements in diving systems have been paramount to increasing the depth and duration of commercial and military diving operations. Even with such advances and the use of proven engineered diving systems, as humans continue to strive for deeper and longer dives, significant risk to all personnel is inherent. Minimization and mitigation of such risk is vital to meet the need for continued use of manned-diving systems to perform specific underwater tasks. This paper will focus on developing mixed qualitative and quantitative risk analysis tools using current human and organizational factors (HOF) research and database software that can be applied to diving operations. Surprisingly, assessment, evaluation, and management of risks associated with diving operations are rarely performed even in today's high-tech environment. Since a major component of the diving operation is the human and organizational element, there should be adequate safety management systems in place to assess their likelihood of failure. Assessment and monitoring are vital to ensure safe procedures in diving operations and require effective operator/diver involvement and training.
