(Signature): Gu Tong (Date): July 2, 2015 Supervised by: Shi Guoyou Professor Dalian Maritime University Assessor: Co-assessor: ii ACKNOWLEDGEMENTS This paper is developed as part of my studies to obtain the master degree of Maritime Safety and Environmental Management (MSEM) at WMU and DMU. I am profoundly grateful to all people who have supported and helped me in various ways during my studies. First and foremost, I would like to express my deepest gratitude to Tianjin VTS, Tianjin MSA, where I have worked for almost 5 years. It is my leaders and colleagues that provide me with this precious opportunity to join the MSEM program in Dalian, and they really helped me a lot with my research paper. I would like to thank my supervisor Professor Shi Guoyou, for his patience and encouragement and for guiding me through the process of this project. His help is indeed valuable. I must give my heartfelt thanks to all professors attending the MSEM 2015 program. Their professional knowledge broadened my eyesight and instilled in me new ideas and methodologies, without which the study would not have been completed. I remain very grateful to all the classmates of MSEM 2015. I thank them for their company and for sharing their views and experiences. Together we experienced a nice time in DMU. iii ABSTRACT Title of Research Paper: Risk Assessment of Water Area Covered by Tianjin VTS Degree: MSc Tianjin port is located in the central position of the Bohai port region of China and it is one of the most important foreign trade ports and the important node of Beijing Tianjin Hebei modernization comprehensive transportation network. With the rapid development of maritime economy, the vessel traffic flow is increasing sharply and marine traffic situation is becoming more and more complex, which brings harmful effects and difficulty on the communication order and traffic organization. How to do with the challenges faced by VTS, how to identify the key sources of risk, and how to optimize risk management have become a series of serious problems. This paper analyzes the characteristics of Navigation, collision avoidance and grounding avoidance in the area covered by Tianjin VTS, and identifies the distribution of ship flow in the area and the trend of water transportation accident, then concludes the preliminary risk factors in the VTS area. The author uses the PAWSA risk analysis method, which is necessary for risk identification, analysis, summary and identify risk level of each VTS partition for Tianjin VTS. After risk assessment, the author tries to come up with the safety recommendations and measures, hoping to do some help to set up new supervision mode of Tianjin VTS. iv KEYWORDS: Risk assessment,
