一、前言以石油危机为主因的原油、天然气的价格的高涨,促进了对存在于北极海域的丰富的能源的开发,近几年来已实现了若干开发项目。在开发北极海域内资源的活动中,需要大量的破冰船等冰海船舶、冰海钻井平台等各种冰海结构物,为耐受苛刻的气象,海象条件、冰的载荷等,要求使用与常规的开发海洋能源的船舶,海洋结构物不同的设计标准及材料。特别
I. Introduction The rising prices of crude oil and natural gas, mainly caused by the oil crisis, have promoted the development of abundant energy resources existing in Arctic waters. In recent years, several development projects have been realized. In the development of resources in the Arctic sea area, a large number of ice-sea vessels such as icebreakers and ice-sea drilling platforms are required. In order to withstand harsh weather conditions, walrus conditions, ice load, and the like, The development of marine energy vessels, marine structures of different design standards and materials. especially
