【摘要】：海上鉆井平臺(tái)是海洋油氣開(kāi)發(fā)的基礎(chǔ)設(shè)施,隨著平臺(tái)的高科技化和大型化,平臺(tái)的安全問(wèn)題受到越來(lái)越多的關(guān)注,：如果平臺(tái)一旦發(fā)生危險(xiǎn),由于平臺(tái)本身及環(huán)境等因素限制,救援將會(huì)非常困難,對(duì)人員、經(jīng)濟(jì)和環(huán)境容易造成巨大危害,對(duì)海上鉆井平臺(tái)的安全評(píng)估變得意義重大。結(jié)合自升式鉆井平臺(tái)平面簡(jiǎn)圖,對(duì)井口附近危險(xiǎn)區(qū)域內(nèi)的設(shè)備、伴有油氣作業(yè)的設(shè)備、平臺(tái)上明火作業(yè)單元及儲(chǔ)存易燃易爆氣體液體的單元進(jìn)行火災(zāi)爆炸危險(xiǎn)源辨識(shí),辨識(shí)容易發(fā)生危險(xiǎn)的設(shè)備及事故原因。利用道化學(xué)評(píng)價(jià)法危險(xiǎn)單元選取標(biāo)準(zhǔn),結(jié)合危險(xiǎn)源辨識(shí)結(jié)果,確定了平臺(tái)上6個(gè)危險(xiǎn)單元,通過(guò)指數(shù)及補(bǔ)償系數(shù)計(jì)算,得到6個(gè)危險(xiǎn)單元的危險(xiǎn)指數(shù)及風(fēng)險(xiǎn)等級(jí)；并從設(shè)備管理、人員、平臺(tái)安全檢查以及防護(hù)措施等幾方面提出降低事故風(fēng)險(xiǎn)措施。進(jìn)行平臺(tái)船舶碰撞模擬研究,從碰撞原因、碰撞環(huán)境以及碰撞力學(xué)機(jī)理上對(duì)碰撞進(jìn)行研究,確定模擬中的初始參數(shù)及分析思路。利用solidworks建立自升式鉆井平臺(tái)與船舶模型,運(yùn)用有限元軟件Ansys Workbench顯示動(dòng)力學(xué)模塊,對(duì)平臺(tái)與船舶碰撞進(jìn)行模擬研究；通過(guò)對(duì)船舶初始狀態(tài)的設(shè)置,使其以不同速度、不同角度與平臺(tái)樁腿發(fā)生碰撞以及在平臺(tái)不同作業(yè)水深時(shí)與樁腿碰撞,對(duì)平臺(tái)進(jìn)行碰撞響應(yīng)分析,分析平臺(tái)危險(xiǎn)部位；計(jì)算平臺(tái)遭遇到供給船和守護(hù)船撞擊的頻率,提出降低風(fēng)險(xiǎn)措施。
[Abstract]:Offshore drilling platform is the infrastructure of offshore oil and gas development. With the development of high technology and large-scale platform, more and more attention has been paid to the safety of the platform. Rescue will be very difficult, easy to cause human, economic and environmental hazards, and the safety assessment of offshore drilling platform becomes significant. Combined with the plane diagram of the jack-up drilling platform, the fire and explosion hazard sources are identified for the equipment in the dangerous area near the well head, the equipment with oil and gas operation, the open fire operation unit on the platform and the unit storing flammable and explosive gas and liquid. Identify dangerous equipment and accident causes. By using the selection criteria of hazard unit and the result of hazard source identification, six hazard units on the platform are determined. The risk index and risk grade of the six risk units are obtained by the calculation of index and compensation coefficient. And from the equipment management, personnel, platform safety inspection and protective measures and other aspects of measures to reduce the risk of accidents. In this paper, the platform ship collision simulation is carried out, the collision cause, collision environment and collision mechanics mechanism are studied, and the initial parameters and analysis ideas in the simulation are determined. Using solidworks to establish the model of jack-up drilling platform and ship, and using the finite element software Ansys Workbench to display dynamics module, to simulate the collision between platform and ship, and to make the ship at different speeds by setting the initial state of the ship. Different angles collide with the leg of the platform and when the water depth of the platform is different, the collision response of the platform is analyzed, the dangerous part of the platform is analyzed, and the frequency of the collision of the platform against the supply ship and the guardian ship is calculated. Risk reduction measures are proposed.
