【摘要】：隨著近年來(lái)能源的需求越來(lái)越大,海洋資源的開(kāi)發(fā)顯得越來(lái)越重要。海洋油氣資源的開(kāi)發(fā)主要依托于浮式平臺(tái),浮式平臺(tái)的系泊系統(tǒng)使平臺(tái)保持在一定的位置正常作業(yè)。懸鏈線式系泊系統(tǒng)由于其結(jié)構(gòu)可靠、簡(jiǎn)單、經(jīng)濟(jì)性好的優(yōu)點(diǎn)目前被大量使用。 懸鏈線系泊系統(tǒng)在初步設(shè)計(jì)過(guò)程中需要考慮環(huán)境參數(shù)、附加質(zhì)量、阻尼、系泊剛度、最大偏移距離、系泊最大張力、浮體RAO等重要參數(shù)。詳細(xì)設(shè)計(jì)過(guò)程中,主要是對(duì)系泊系統(tǒng)的強(qiáng)度和疲勞性能進(jìn)行分析。其中對(duì)于懸鏈線式多點(diǎn)系泊系統(tǒng)中系泊力的確定,對(duì)其設(shè)計(jì)和在位時(shí)的系泊性能分析都具有重要的意義。隨著海域水深的增加,由于縮比和非線性的影響使模型試驗(yàn)和數(shù)值模擬存在不足。 本文對(duì)考慮彈性形變的懸鏈線方程和浮體運(yùn)動(dòng)進(jìn)行分析,基于懸鏈線方程的定解條件提出通過(guò)測(cè)量浮體六自由度運(yùn)動(dòng)信息和錨泊線姿態(tài)變化來(lái)測(cè)量錨泊力的方法。以我國(guó)南海LH11-1油田的半潛式FPS為依托,對(duì)其系泊系統(tǒng)實(shí)施了原型測(cè)量。通過(guò)對(duì)測(cè)量數(shù)據(jù)的分析,確定測(cè)量方法的誤差滿足工程中測(cè)量的需求。對(duì)懸鏈線的各參數(shù)進(jìn)行分析,得出了相互之間的變化關(guān)系,并據(jù)此分析了采用兩個(gè)傾角傳感器測(cè)量錨泊力時(shí)影響測(cè)量精度的因素和注意事項(xiàng)。最后通過(guò)對(duì)實(shí)測(cè)的角度進(jìn)行統(tǒng)計(jì)和譜分析,得出錨泊線運(yùn)動(dòng)具有波頻部分,并且在惡劣的環(huán)境下波頻部分增大,但是其能量在運(yùn)動(dòng)總能量中占的比例減小。懸鏈線式系泊系統(tǒng)原型測(cè)量技術(shù)的研究,可以作為分析系泊系統(tǒng)的重要手段,且可以作為其他浮式結(jié)構(gòu)的原型測(cè)量的借鑒,具有重要的工程意義。
[Abstract]:With the increasing demand for energy in recent years, the development of marine resources is becoming more and more important. The exploitation of offshore oil and gas resources mainly depends on the floating platform, and the mooring system of the floating platform keeps the platform in a certain position. Catenary mooring system is widely used because of its reliability, simplicity and economy. In the preliminary design of catenary mooring system, some important parameters, such as environment parameters, additional mass, damping, mooring stiffness, maximum offset distance, mooring maximum tension, floating body RAO and so on, should be considered. In the process of detailed design, the strength and fatigue performance of mooring system are analyzed. It is of great significance for the determination of mooring force in catenary multi-point mooring system and the analysis of mooring performance when it is in position. With the increase of water depth, the model test and numerical simulation are insufficient due to the influence of shrinkage ratio and nonlinear. In this paper, the catenary equation and the motion of floating body considering elastic deformation are analyzed. Based on the conditions of the fixed solution of catenary equation, a method of measuring the mooring force by measuring the motion information of the floating body with six degrees of freedom and the change of the mooring line attitude is presented. Based on semi-submersible FPS of South China Sea LH11-1 oilfield, prototype survey of mooring system is carried out. Through the analysis of measurement data, the error of measurement method is determined to meet the requirement of engineering measurement. Based on the analysis of the parameters of catenary, the relationship between the parameters of catenary is obtained, and the factors that affect the measurement accuracy and the matters needing attention when the anchor force is measured by two inclination sensors are analyzed. Finally, through the statistical and spectral analysis of the measured angle, it is concluded that the mooring line motion has the wave frequency part, and the wave frequency part increases under the bad environment, but the proportion of its energy in the total energy of the motion decreases. The research on prototype measurement technology of catenary mooring system can be used as an important means to analyze mooring system, and can be used as a reference for other floating structure prototype measurement, which has important engineering significance.
