Book Description
In FY 1990, Congress directed the Secretary of the Navy to commission a study by the National Academy of Sciences for the production of an integrated technology plan for the evolution of aircraft carriers in the first half of the twenty-first century. The House-Senate conferees emphasized "that the product of this study is to be a technology plan for the evolution of sea bases for the most efficient and economical accommodation of tactical air power in the first half of the twenty-first century". Based on this broad charter of evaluating sea bases, an examination of the floating ocean platform concept was included in the study. The floating ocean platform is a generic description of a large, relatively stationary or slowly mobile, platform that can be positioned in most areas of the ocean, and can serve a variety of purposes. The present report was the author's input to the study. It was based on technical analyses, literature reviews and surveys, and discussions/visits with the main groups and organizations involved in developing the floating ocean platform. All discussion material was unclassified, as are the contents of this report. All the external inputs and discussions, too numerous to mention, made this report possible, and are greatly appreciated. The first part of this report is the summary narrative that was submitted by the author to the Technology Group of the study. The second part is the viewgraphs that were presented to the Technology Group by the author on 12 February 1991. The third part is a selected bibliography of studies on the floating ocean platform over the past two decades, with over three thousand references identified.

Book Description
This report details a Naval Undersea Center five-year study on the hydrodynamics of floating stable ocean platforms constructed from repetitively cast concrete modules. The effort centered on analytical prediction and measurement through model testing of the following design aspects for several platform configurations: (1) Platform heave, pitch, roll, yaw, surge and sway motion due to wave action; (2) horizontal drag forces in various sea states; (3) structural forces on modules due to wave action; and (4) underwater submersible docking in a module.

Book Description
Offshore platforms are widely used to explore, drill, produce, store and transport ocean resources, and are usually subjected to environmental loading, which can lead to deck facility failure and platform fatigue failure, inefficient operation and even crew discomfort. In order to ensure the reliability and safety of offshore platforms, it is important to explore effective ways of suppressing the vibration of offshore platforms. This book provides a brief overview of passive, semi-active and active control schemes to deal with vibration of offshore platforms. It then comprehensively and systematically discusses the recent advances in active systems with optimal, sliding model, delayed feedback and network-based control. Intended for readers interested in vibration control and ocean engineering, it is particularly useful for researchers, engineers, and graduate students in the fields of system and control community, vibration control, ocean engineering, as well as electrical and electronic engineering.
