Japan Ocean Industries Association (hereafter JOIA) has been organizing the research project, "Study on Ice Load Acting on Marine Structures", since the fiscal year of 1993. The motivation behind the project was the national security of Japan which to secure steady and abundant energy resources for a long time period is one of vital needs for Japan. Cold regions, especially ice-covered waters were recognized as regions where could be important for future developments of natural energy resources. Therefore, JOIA planned the research project to obtain better understandings ice load on marine structures in order to design safe and economical structures for the future developments. It has been five years past since the project started. What the project has done and what the project has obtained from those studies are summarized in this report. And a future plan is also stated. Because of the page limitation, many details of the studies are not presented in the paper. The authors wish to see the references.
The project was originally planned as five years project with three task working groups. The Working Group (WG) on Technical Survey has summarized the current status of the related technology and fed them to the other working groups. The WG on Ice Tank Experiments has engaged to establish numerical codes to estimate ice loads on both vertical sided and conical structures through utilizing results from ice tank experiments.
