T H E OFFSHORE TECHNOLOGY CONFERENCE is the world's largest and most comprehensive technical conference and exhibition on offshore resource development. The Conference is jointly sponsored by eleven major intemational engineering and scientific organizations that have a total membership of some 700,000 professionals.
The OTC technical program combines the expertise offered by the eleven engineering and scientific organizations. Authors from 27 nations will present practical applications, theory, and research findings on all facets of ocean resource development in the 1993 program, The papers have been placed in 47 sessions covering both state-of-the-art and new technology in every area of offshore resource development.
The four Proceedings volumes have been separated by major areas of interest, with sessions included in each volume listed below. Papers are listed by OTC number, and most are in numerical order.
