REVIEW OF DATA RELEVANT TO THE DESIGN OF TUBULAR JOINTS FOR USE IN FIXED OFFSHORE PLATFORMS

The report is divided into four essentially self-contained chapters, each with its own Table of Contents, Nomenclature, and References. The title of the chapters are: (1) Static Strength, (2) Stresses, (3) Fatigue, and (4) Displacements. API RP2A "Recommended Practice for Planning, Designing and Constructing Fixed Offshore Platforms" contains, among many other things, criteria for the static- strength design of simple tubular joints. Also, through its reference to AWS Section 10 of D1.1, "Design of New Tubular Structures," API RP2A provides criteria for the fatigue-strength design of simple tubular joints. The review of available test and theoretical data indicates that the criteria of API RP2A are supported by a substantial amount of data and give engineering quidance of quality equivalent to that contained in the ASME Boiler Code, Section III, Nuclear Power Plant Components. Indeed, the support data for tubular joints are more extensive and complete than in the nuclear power plant components area; which faces similar problems of static strength and fatigue evaluation. This report was prepared during the time where API RP2A--January, 1976 and AWSD1.1--1975 were current documents. Chapter 1 contains some comparisons with "API RP2A--1978." However, these comparisons were limited to certain criteria proposed by P.W. Marshall, and accepted by API for revision to APIRP2A--1976. Since completing this report, revisions of both the API and AWS documents have been made. Some of the comments made in this report may not be applicable to now-current versions of the API and AWS documents.
