Subsea Engineering handbook
2012Co-Authors: Yong Bai, Qiang BaiAbstract:Designing and building structures that will withstand the unique challenges that exist in Subsea operations is no easy task. As deepwater wells are drilled to greater depths, engineers are confronted with a new set of problems such as water depth, weather conditions, ocean currents, equipment reliability, and well accessibility, to name just a few. A definitive reference for engineers designing, analyzing and instilling offshore structures, "Subsea Structural Engineering Handbook" provides an expert guide to the key processes, technologies and equipment that comprise contemporary offshore structures. Written in a clear and easy to understand language, the book is based on the authors 30 years of experience in the design, analysis and instillation of offshore structures. This book answers the above mentioned crucial questions as well as covers the entire spectrum of subjects in the discipline, from route selection and planning to design, construction, installation, materials and corrosion, inspection, welding, repair, risk assessment, and applicable design solutions. It yields a roadmap not only for the Subsea engineer but also the project managers, estimators and regulatory personnel hoping to gain an appreciation of the overall issues and directed approaches to Subsea Engineering design solutions. This title features up-to-date technical overview of deepwater riser Engineering. It is easy to understand. It includes coverage of design, analysis and, stallation. It addresses issues concerning both fixed and floating platforms. It covers technical equipment such as Subsea Control Systems, Pressure Piping, Connectors and Equipment Layout as well as Remotely-operated vehicles.

Overview of Subsea Engineering
Subsea Engineering Handbook, 2010Co-Authors: Yong Bai, Qiang BaiAbstract:The Subsea technology used for offshore oil and gas production is a highly specialized field of application that places particular demands on Engineering. This chapter discusses four parts of Subsea Engineering: production systems, flow assurance and system Engineering, Subsea structures and equipment, and Subsea umbilicals, risers, and pipelines. A Subsea production system consists of a Subsea completed well, seabed wellhead, Subsea production tree, Subsea tie-in to flowline system, and Subsea equipment and control facilities to operate the well. It can range in complexity from a single satellite well with a flowline linked to a fixed platform, FPSO (Floating Production, Storage and Offloading), or onshore facilities, to several wells on a template or clustered around a manifold that transfer to a fixed or floating facility or directly to onshore facilities. After the production system has been installed, numerous operations are in place to ensure safe and pollution-free operations and support the continued flow of hydrocarbons. Facilities and pipelines require periodic inspections to ensure that no external damage or hazards are present that will affect the system's integrity.

ROV Intervention and Interface
Subsea Engineering Handbook, 2010Co-Authors: Yong Bai, Qiang BaiAbstract:This chapter provides an overview of the state of the art for Subsea remote intervention and vehicles, remote operated vehicles (ROV) technologies, and ROV capabilities and requirements for Subsea operations. (ROVs) and remote-operated tools (ROTs) are required to carry out Subsea tasks that divers cannot reach. An ROV is a free-swimming submersible craft used to perform Subsea tasks such as valve operations, hydraulic functions, and other general tasks. An ROT system is a dedicated, unmanned Subsea tool used for remote installationormodule replacement tasks that require lift capacity beyond that of free-swimming ROV systems. Generally, ROVs are used for these issues, which are detailed in the following sections: site survey; drilling assistance; installation assistance; operation assistance; inspection; and maintenance and repair. An ROV system used in Subsea Engineering can be divided into the following subsystems: control room on deck for controlling the ROV Subsea; workover room on deck for ROV maintenance and repair; deck handling and deployment equipment, such as A-frame or crane/winch; umbilical to power ROV Subsea and launch or recover ROV; tether management system to reduce the effect of umbilical movement on the ROV; ROV for Subsea intervention.

Installation and Vessels
Subsea Engineering Handbook, 2010Co-Authors: Yong Bai, Qiang BaiAbstract:The objective of this chapter is to provide a basic understanding of the installation concepts and vessel requirements for Subsea Engineering. The topics covered in this chapter are: typical installation vessels; vessel requirements and selection; installation positioning; and installation analysis. Subsea structures are normally transported from onshore to the offshore installation site by a transportation barge. Once at the offshore installation site, the Subsea structure is transferred from the transportation barge to the drilling rig or construction vessels. Drilling vessels are mainly designed for drilling activities, but they are also used for the Subsea Production System (SPS) installation because of their installation capacities such as water range, lifting capacity, and positioning capacity. Installation of Subsea hardware requires the vessel to keep its position well so that the Subsea hardware can be placed onto the target foundation with the required accuracy. Two methods are widely used for Subsea hardware installation: the guideline (GL) method and the guideline-less (GLL) method. Installation analysis is a type of calculation for the validation of lifting capacity, strength capacity for lifting objects and vessel structures, etc. Installation analysis can be divided into two categories based on different phases of installation Engineering: preliminary installation analysis of the front-end Engineering design (FEED) for determining the installation method, installation vessels and equipment, as well as the relevant installation duration and cost estimations, and detailed installation analysis of the Engineering design with the goal of developing and installation procedure and relevant installation drawings.

Subsea Engineering ROV and seafloor observatory construction
2011 IEEE Symposium on Underwater Technology and Workshop on Scientific Use of Submarine Cables and Related Technologies, 2011Co-Authors: Katsuyoshi Kawaguchi, Sho Kaneko, Takato Nishida, Eiichiro Araki, Tetsuya KomineAbstract:Marine science starts shifting from the age of the exploration in the age of the observation. For the abyss research, submarine cabled seafloor observation is one of the expected Engineering approaches to be realized real-time and long term observation of natural phenomenon. The DONET (Dense Ocean-floor Network system for Earthquakes and Tsunamis) is a submarine cabled seafloor observatory network design for earthquakes and tsunamis monitoring at the western part of the Pacific Rim. Twenty set of high performance observatories are installed to the seafloor in this project. One of the most difficult Engineering in the project is to establish construction method of complex sensor observatory on seafloor. The use of ROV is necessary in the Subsea construction. This paper describes the construction method of seafloor seismic observatory, tools design for construction, and experience result in an actual field.

Type-2 fuzzy logic neural network control and target following for Remote Operated Vehicles
2012 IEEE International Conference on Mechatronics and Automation, 2012Co-Authors: Huang Hai, Jiang Shu-qiang, Wan Lei, Pang Yong-jieAbstract:Accurate control and target following are very important for Remote Operated Vehicles Subsea Engineering. In order to make Remote Operated Vehicles task more effective and accurate, type-2 fuzzy logic neural network has been introduced to model and minimize the effects of uncertainties in rule-base fuzzy logic system. In the online learning strategy, the gradient descent method has been used for online training. The results of tank experiments have proved that the controller can improve the computation efficiency, reduce control errors, vibration and overshoot. Thus the controller displays strong robustness in the underwater robotic control. In the 3-D target following simulations, ROV can precisely follow the target in still and current underwater enviroment. These simulations verify the controller's capacity to realize 3D-trajectory control and target following. It can realize 3D-target following curve tracking, obstacle avoidance and guarantee underwater task accomplishment.
