The author has designed over one hundred major tanks that store plastic powders and pellets. This article gives some practical examples of how to analyze and design plastic storage tanks. Examples were taken from files of completed projects. All tanks are classified as either shallow or deep; an example of each is given. A series of four articles was written to report on a study about vessels made of aluminum or steel, and joined by bolting or welding. The first three articles are “Bolted Aluminum—Alloy Connections,” “Welded Tanks for Dry Bulk Plastic Storage,” and “Bolted Tanks for Storage of Plastics.” The state-of-the-art is presented. Although computer programs have been developed, some equations still used are empirical, and the assumptions are conservative. Not all authorities agree on the proper method of analysis. A research study of the whole tank, rather than its parts, should be made.

This is a paper that summarizes the state of the practice and state of the art in the prediction of seismic behavior of cylindrical liquid storage tanks. It can be divided into five parts. In the first part the seismic performance of these types of tanks during recent   earthquakes is brielfly reviewed. From this review it becomes evident that a large percentage of these tanks have failed or suffered severe damages. The different types of failure are classified into several categories. The second part of the paper discusses the desing of some of the thank that suffered damages andthe state of the practice is summarized by reviewing present seismic code desing provisions. Thirdly, the soundness of these code provisions is analyzed in view of the state of thank.  Results obtained in recent theoretical and experimental investigations of such behavior are summarized and implications regarding needed improvement in seismic desing are assessed. Results from analyses of an existing  thank using different methods are presented and compared. An improved procedure for the practical seismic resistant desing of these thanks is outlined in the fourth part of the paper. A series of practical desing rules which provide extra margins of safety are offered and the extra cost required is discussed. Finally, recommendations for future research to improve the desing and construction of this type of liquid storage thanks are formuated.

The Past

This is a review of selected publications over the past eight years, dealing with the analysis and design of self-acting, gas-lubricated bearings. An effort has been made to evaluate the advances made both in the understanding of the basic phenomena involved and in the technical analytical ability to deal with them. Whenever possible, design procedures have been referenced and illustrated.

This paper describes the installation planning for a major self-floating offshore platform that recently has been installed in the North Sea. Attention is given to the naval architectural aspects of the installation planning with particular emphasis on three phases: analysis and design, scale-model testing, and field activity preceding and during the actual installation operation. The paper describes the state-of-the-art in the installation planning of major self-floating offshore platforms of the kind being designed and built worldwide, and demonstrates the close coordination of many diverse disciplines in planning such installation operations.
