FOREWORD

The purposes of the ISOPE conference are to:

- promote technological progress and activities, the intemational technological transfer and cooperation, and opportunities for engineers to maintain and improve technical competence; and

- provide a timely intemational fomm for the technical activies, cooperation, opportunity and fellowship among researchers and engineers,

by developing focused session topics with high quality (in both originality and significance) papers accepted through rigorous review, establishing a high intemational standard for publication and worldwide distribution and promoting interdisciplinary interaction between academia and industry.

The International Society of Offshore and Polar Engineers (ISOPE) has already held 7 successful international meetings: First (1990) Pacific/Asia Offshore Mechanics Symposium (PACOMS-90), Seoul, 1990; First (1990) European Offshore Mechanics Symposium (EUROMS-90), Trondheim, 1990; ISOPE-91, Edinburgh, 1991; ISOPE-92, San Francisco, 1992; ISOPE-93, Singapore, 1993; and ISOPE-94, Osaka, 1994, and Special Offshore Symposium China (SOSC-94/PACOMS-94), Beijing, 1994.

This year the 5th Intemational Offshore and Polar Engineering Conference (ISOPE-95), The Hague, June 11-16, 1995, for the second time since 1989, features 6 plenary and 66 technical sessions from industry, academia and govemment. Authors from 36 countries present some 370 380 refereed papers on recent worldwide developments in frontier technologies in:

Offshore Resources & Energy, Offshore Mechanics and Technology, Environment, Geotechnical Engineering, Offshore and Arctic Pipelines, Risers, Mechanics of Cables & Mooring, AUV, ROV & Robotics, Ice Technology, Russian Arctic, Hydrodynamics, Tubular Structures, Materials, Welding & Corrosion, Composite Materials, Mechanics & Applications, Reliability & Safety, Computational Mechanics, Marine & Ship Technology, and other emerging topics.

We greatly appreciate the help from colleagues around the world in the successful organization of ISOPE-95, particulariy from the authors and reviewers in meeting deadlines. On behalf of all the individual TPC members (listed in this volume), we would like to thank the reviewers (listed in this volume) for their help in maintaining the technical accuracy and q u a l i t y of papers. The cooperation from IRO, The Netherlands, Delft University o f Technology, and Colorado School of Mines, and the efficient handling of the conference organization by the ISOPE staff are greatly appreciated.

On behalf of the Technical Program Committee, it is our pleasure to welcome participants from all over the world to the 95 Conference, a truly international conference. The ISOPE-96 Conference will be held in Los Angeles, May 26-31, 19ISOPE-96.
