深海平台立柱周围波浪非线性爬升研究进展

随着深海油气田的不断开发,各种适应深海环境的浮式平台陆续涌现。多数深海平台通过立柱支撑上层甲板,波浪沿柱体表面的爬升效应极为明显,大大增加了强非线性砰击和越浪的危险,甚至将导致平台局部结构以及相关设备的破坏。因此,波浪爬升效应在平台设计及结构安全性方面具有重要的意义,并成为平台水动力研究的热点问题之一,是平台气隙预报的一个重要方面。介绍波浪爬升效应在平台设计阶段的重要性,分析波浪爬升的成因和影响因素,就目前国际上相关研究情况及进展进行了详细的阐述,并提出了这一课题未来研究方向的有关建议。

Review of the research on non-linear wave run-up around columns of deepwater platform

with the continuous development of deepwater oil and gas fields,many new types of floating platforms suitable for deepwater environments are emerging.The decks of most deepwater platforms are supported through columns.The wave run-up effects around columns are signifiant mostly,which will largely increase the risk of strong non-linear impacts and green water,even destroy the local deck and relative facilities of platforms.So wave run-up effects on design of platforms and structure safety are extremely important,even becoming one of hot topics in platform hydrodynamics.It is an important part of air-gap predictions.The importance of wave run-up effects in design process is introduced in this paper.The causes and factors of wave run-up are analysed.Furthermore,the related studies and developements in recent years are also presented in detail.The suggestions for further studies in this field are made as well.
