摘要
海洋石油102水上软钢臂式系泊系统在发生YOKE压溃事故后,对其YOKE结构进行了相应的加强,但改造造成的潜在影响尚未明晰。本文从结构强度角度,分析YOKE加强环改造影响,计算结果表明,认为改造后YOKE结构主要影响为由原有的弹性形变占主要作用变为刚性的应力集中占主要作用,改造后的储备强度不完全满足使用要求,应尽快对其进行相应加强。
The yokestructural was reinforced after Haiyangshiyou 102 soft YOKE mooring system collapsed,but,there＇s no reliable impact analysis of the modification. This paper analysed the structural impact with FEA method. Results has shown that the elastic--deformation--dominance has turned into stresses--concentration--dominance,which is not enough to meets the requirement.
