FOREWORD

Offshore deep water development is progressing in full swing all over the world. Record water depth drilling and production is being seen observed at a steady pace. Structures that are receiv-ing special attention in these developnnents are the floatreceiv-ing offshore structures.

This trend is continuing in this year's Offshore Technology Symposium. A large number of papers deal with floating moored systems, including risers and cables. Other areas receiving spe-cial interest at the symposium include ocean wave analysis and hydrodynamic analysis. In gen-eral, the response this year has been quite enthusiastic. A total of about 9 5 papers will be pre-sented at the Offshore Technology Symposium. The subject matter is varied and includes the fol-lowing topics:

• Ocean Wave Mechanics

' Computations of Hydrodynamic Forces • Offshore Structures Design

• Structural Mechanics • Risers and Cables

• Floating and Moored Structures • Ship Dynamics

• Jackets and Tension Leg Platforms • Ocean Energy Technology

The development of the symposium sessions is a culmination of enthusiastic, and volunteer efforts of the session organizers. This year there has been a special effort put forth by the Japanese Session Organizers. With the help of their reviewers, the session organizers have ensured that quality papers are presented at this conference. The conference organizing com-mittee recognizes and acknowledges their efforts.
