【摘要】：隨著工業(yè)發(fā)展對(duì)自然資源的消耗，陸地上的石油、天然氣資源日益枯竭，淡水資源也極度貧乏。而在大海的深處恰恰蘊(yùn)藏著大量的油氣及淡水資源，因此，，海洋工程的發(fā)展，勢(shì)必走向深海。 深海資源的開發(fā)需要面對(duì)惡劣的海洋環(huán)境，因此需要重量更大，結(jié)構(gòu)更強(qiáng)的海洋結(jié)構(gòu)物才能完成這一任務(wù)，而這種結(jié)構(gòu)物的安裝日益受到人們關(guān)注。浮托安裝法是針對(duì)于特大型海上結(jié)構(gòu)的一種極具發(fā)展前景的安裝方法，它利用潮水變化帶來的巨大浮力，將重量巨大的海上結(jié)構(gòu)從浮托駁船上轉(zhuǎn)移到預(yù)定的支撐結(jié)構(gòu)上，完成安裝過程。 本文以荔灣3-1的浮托安裝的過程為背景，研究對(duì)浮托安裝過程的實(shí)測(cè)技術(shù)，并根據(jù)實(shí)測(cè)結(jié)果，對(duì)浮托安裝的數(shù)值預(yù)報(bào)技術(shù)進(jìn)行對(duì)比研究。 進(jìn)行的主要工作有：利用GPS/INS監(jiān)測(cè)駁船六自由度運(yùn)動(dòng)；利用X波段測(cè)波雷達(dá)得到浪、流；利用壓力式潮位儀和機(jī)械式風(fēng)速儀監(jiān)測(cè)潮位及風(fēng)；利用光纖應(yīng)變片監(jiān)測(cè)駁船護(hù)舷載荷；監(jiān)測(cè)數(shù)據(jù)的集成顯示；對(duì)實(shí)測(cè)結(jié)果的質(zhì)量進(jìn)行分析，并將處理后的實(shí)測(cè)結(jié)果應(yīng)用于浮托數(shù)值計(jì)算，對(duì)比分析出數(shù)值計(jì)算在預(yù)報(bào)浮托安裝過程中的可靠性。 得到的主要結(jié)論有：本文給出了一套浮托安裝過程中，駁船運(yùn)動(dòng)和海洋環(huán)境的精確測(cè)量方案；給出了一種經(jīng)濟(jì)有效的護(hù)舷載荷估算方法；設(shè)計(jì)出一套方便于工程應(yīng)用的數(shù)據(jù)通訊與集成顯示方案。相應(yīng)的，成功測(cè)量出可靠的實(shí)際數(shù)據(jù)，可應(yīng)用于對(duì)比模型試驗(yàn)與理論計(jì)算結(jié)果；通過與理論計(jì)算的對(duì)比分析，得出通過采取合理的數(shù)值波浪模型及粘性阻尼系數(shù)，時(shí)域分析方法能夠較為可靠的預(yù)報(bào)浮托駁船的波頻運(yùn)動(dòng)情況的結(jié)論。
[Abstract]:With the consumption of natural resources by industrial development, the oil and natural gas resources on land are exhausted day by day, and the fresh water resources are also extremely poor. There are a lot of oil and gas and fresh water resources in the depths of the sea, therefore, the development of marine engineering is bound to go to the deep sea. The development of deep-sea resources needs to face the bad marine environment, so it needs heavier and stronger marine structures to complete this task, and the installation of this kind of structures has attracted more and more attention. Float installation method is a promising installation method for super large offshore structures. it transfers the heavy offshore structure from the buoy barge to the predetermined support structure by using the great buoyancy caused by the tide change, and completes the installation process. In this paper, based on the installation process of the float in Liwan 3 / 1, the measured technology of the installation process of the float is studied, and the numerical prediction technology of the installation of the float is compared according to the measured results. The main work is as follows: using GPS/INS to monitor the movement of barge with six degrees of freedom; using X-band wave radar to get waves and currents; using pressure tidal level gauge and mechanical anemometer to monitor tide level and wind; using optical fiber strain gauge to monitor barge fender load; integrated display of monitoring data; The quality of the measured results is analyzed, and the processed measured results are applied to the numerical calculation of the float, and the reliability of the numerical calculation in the process of predicting the installation of the float is compared and analyzed. The main conclusions are as follows: in this paper, a set of accurate measurement scheme of barge motion and marine environment in the process of float installation is given, an economical and effective method of fender load estimation is given, and a set of data communication and integrated display scheme is designed, which is convenient for engineering application. Accordingly, reliable practical data can be successfully measured, which can be applied to compare the results of model test and theoretical calculation, and through the comparative analysis with theoretical calculation, it is concluded that the time domain analysis method can predict the wave frequency motion of buoy barge more reliably by adopting reasonable numerical wave model and viscous damping coefficient.
