【摘要】：當(dāng)陸上油氣資源經(jīng)過(guò)長(zhǎng)期開(kāi)采之后,海洋石油成為主攻方向,走向深水及超深水是世界海洋油氣工業(yè)發(fā)展的必然趨勢(shì)。半潛式鉆井平臺(tái)和鉆井船是如今全球范圍內(nèi)僅有的具有能夠在超過(guò)1500米水深區(qū)域進(jìn)行深遠(yuǎn)海水域鉆探的兩種裝備形式。其中半潛式鉆井平臺(tái)是深遠(yuǎn)�？碧降闹髁餮b置之一。壓載系統(tǒng)的設(shè)計(jì)是半潛式鉆井平臺(tái)設(shè)計(jì)重要的關(guān)鍵技術(shù)之一,平臺(tái)的浮態(tài)對(duì)于其在各種工況下的性能有著極其重要的影響。美國(guó)船級(jí)社移動(dòng)平臺(tái)規(guī)范(ABS MODU)對(duì)半潛式鉆井平臺(tái)壓載/卸載速率有一個(gè)強(qiáng)制性要求,同時(shí)該系統(tǒng)應(yīng)能在平臺(tái)假定破損條件下保證有效操作,規(guī)范對(duì)壓載泵的配置有失艙的要求。本文主要根據(jù)目標(biāo)平臺(tái)的設(shè)計(jì)要求,在滿足平臺(tái)總體性能的基礎(chǔ)上,通過(guò)學(xué)習(xí)吸收國(guó)外先進(jìn)的技術(shù)與經(jīng)驗(yàn),按照ABS規(guī)范的要求,同時(shí)根據(jù)以往的工程設(shè)計(jì)經(jīng)驗(yàn)對(duì)壓載系統(tǒng)的設(shè)計(jì)進(jìn)行了研究。從注入/排出方式、液位測(cè)量、閥門(mén)控制、設(shè)備配置和容量計(jì)算、系統(tǒng)吸入性能和阻力降估算等不同方面進(jìn)行了詳細(xì)的分析和全面的比較,并根據(jù)比較結(jié)果,選出適用于目標(biāo)平臺(tái)的最優(yōu)配置方案。解決了平臺(tái)在假定破損狀態(tài)下至少有兩臺(tái)泵能夠有效的排空每一個(gè)壓載艙,以及平臺(tái)在規(guī)范允許的最大傾斜角破損工況下系統(tǒng)能正常吸入的關(guān)鍵技術(shù)難點(diǎn),保證了平臺(tái)在任何規(guī)范要求的工況下均能保持正常的浮態(tài),并滿足系統(tǒng)風(fēng)險(xiǎn)可操作性分析(HAZOP)的要求。經(jīng)過(guò)系泊試驗(yàn)和航行試驗(yàn)等的驗(yàn)證,平臺(tái)的各項(xiàng)指標(biāo)均已達(dá)到設(shè)計(jì)要求,亦可證明其壓載系統(tǒng)的設(shè)計(jì)是成功的。
[Abstract]:When onshore oil and gas resources are exploited for a long time, offshore oil becomes the main attack direction, and it is an inevitable trend for the development of offshore oil and gas industry in the world to move towards deep water and ultra deep water. Semi-submersible drilling platforms and drilling vessels are the only two types of equipment in the world which can drill in deep and far sea waters in more than 1500 meters of water depth. The semi-submersible drilling platform is one of the main equipments in the deep sea exploration. The design of ballast system is one of the key technologies in the design of semi-submersible drilling platform. The floating state of the platform has an extremely important influence on its performance under various operating conditions. American Classification Society Mobile platform Specification (ABS MODU) has a mandatory requirement for ballast / unloading rate of semi-submersible drilling platforms. At the same time, the system should be able to ensure effective operation under the assumption of platform breakage, and the requirements of the specification for ballast pump configuration are lost. In this paper, according to the design requirements of the target platform, on the basis of satisfying the overall performance of the platform, through learning and absorbing advanced foreign technology and experience, according to the requirements of the ABS specification, At the same time, the design of ballast system is studied according to the past engineering design experience. Detailed analysis and comprehensive comparison are carried out from different aspects, such as injection / discharge mode, liquid level measurement, valve control, equipment configuration and capacity calculation, system suction performance and resistance drop estimation, and according to the comparison results, The optimal configuration scheme suitable for the target platform is selected. It solves the key technical difficulties that the platform can effectively empty each ballast tank under the assumption that there are at least two pumps in the damaged condition and that the platform can inhale normally under the condition of the maximum angle of breakage permitted by the specification. It ensures that the platform can maintain a normal floating state under any standard conditions and meet the requirements of system risk operability analysis (HAZOP). After the test of mooring and navigation, each index of the platform has met the design requirements, and the design of the ballast system is proved to be successful.
