摘要
畸形波具有波高巨大、传播速度极快、偶发性强和能量集中等特点,对海洋平台的破坏尤为突出.论文以生产平台和支持平台为研究对象,通过数值模拟与模型试验相结合的方法,对双平台联合作业在畸形波作用下受到的波浪砰击进行研究.运用经过模型试验修正的数值模拟,采用组合波聚焦模型建立畸形波.以典型畸形波"新年波"为例,在时域上开展畸形波工况下双平台多浪向波浪砰击特性研究.研究成果对双平台联合作业的设计与工程应用具有一定的指导和参考价值.
Abstract
Freak waves have the characteristics of huge wave height,extremely fast propagation speed,strong sporadicity,and energy concentration,and its damage to offshore platforms is particularly prominent.The paper takes a production platform and a support platform as the research object to study wave slamming characteristics of the dual-platform under the action of freak waves through numerical simulation and model test.A combination wave focusing numerical model,which is corrected by the model test,is used to establish the freak wave.Taking the typical freak wave"New Year wave"as an example,wave slamming characteristics of the dual-platform are studied in the time domain with multi-wave directions.The research results have certain reference value for the design and engineering application of dual-platform joint operation.
