摘要
船舶应急抛锚贯入深度对海底管线的埋深有着重要的参考价值,为深入研究当前船舶应急抛锚贯入深度计算方法在相同工况下的特点及适用性,对基于Young公式和基于有限元模拟的船舶应急抛锚贯入深度计算方法进行分析并作对比.结果表明,两种方法的计算结果总体一致,但基于有限元模拟的船舶应急抛锚贯入深度计算方法得到的贯入深度值较大,这可为相关的海底原油管线保护埋深设置时,船舶应急抛锚贯入深度计算提供参考.
Abstract
The depth of emergency anchoring has important reference value to the buried depth of submarine pipe-lines,in order to compare the characteristics and applicability of the existing methods for calculating the penetration depth of ship emergency anchoring under the same working conditions,this paper analyzed and compared the calcu-lation process of ship emergency anchoring based on Young formula and finite element simulation.The results show that the calculation method of emergency anchoring penetration depth based on finite element simulation has a large penetration depth value.The study in this paper can provide a theoretical basis for the calculation of emergency an-choring penetration depth when the protection depth of submarine crude oil pipelines is set.This study can provide theoretical basis for the relevant buried depth setting of submarine oil pipeline protection.
