Study of Pipeline Installation in Ultra-Deep Water with S-Lay

Dr. Zhang Xiangfeng, State Key Laboratory of Structural Analysis for Industrial Equipment, Dalian University of Technology, Dalian, 116023, China Email: [email protected] Since the requirement of oil and gas resource becomes more and more severe, the offshore industry is moving into very deep waters. Different methods are adopted to install marine pipelines, such as S-lay and J-lay methods in deepwater and ultra-deepwater, and Reel lay is also considered but only for installation of small diameter pipe In view of deep water challenges, we need to solve demanding line pipe technology aspects, to develop a new and reliable installation technology for ultra deep waters and difficult sea bottoms, to find the suitable technological measures to tackle environmental hazards, typical of ultra deep waters. S-lay is useful and efficient pipe laying method, which has been proved in actual engineering, its pipe-lay capability is mostly depended on the stinger the pipe lays on when laying, and it still has many problems. In our laboratory, we have received one of the National Hi-Tech Research and Development Program (863) of China, and now studying the deepwater S-lay method and the stinger. To work on this project, the student is encouraged to focus on the following topics: 1. read references about deepwater pipelay, especially S-lay 2. analyze the lay ability of S-lay 3. monitor some important part of the stinger when laying References 1.
