【摘要】:海上鉆井平臺是海洋油氣開發(fā)的基礎(chǔ)設(shè)施,隨著平臺的高科技化和大型化,平臺的安全問題受到越來越多的關(guān)注,:如果平臺一旦發(fā)生危險,由于平臺本身及環(huán)境等因素限制,救援將會非常困難,對人員、經(jīng)濟和環(huán)境容易造成巨大危害,對海上鉆井平臺的安全評估變得意義重大。結(jié)合自升式鉆井平臺平面簡圖,對井口附近危險區(qū)域內(nèi)的設(shè)備、伴有油氣作業(yè)的設(shè)備、平臺上明火作業(yè)單元及儲存易燃易爆氣體液體的單元進行火災(zāi)爆炸危險源辨識,辨識容易發(fā)生危險的設(shè)備及事故原因。利用道化學(xué)評價法危險單元選取標準,結(jié)合危險源辨識結(jié)果,確定了平臺上6個危險單元,通過指數(shù)及補償系數(shù)計算,得到6個危險單元的危險指數(shù)及風(fēng)險等級;并從設(shè)備管理、人員、平臺安全檢查以及防護措施等幾方面提出降低事故風(fēng)險措施。進行平臺船舶碰撞模擬研究,從碰撞原因、碰撞環(huán)境以及碰撞力學(xué)機理上對碰撞進行研究,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與船舶模型,運用有限元軟件Ansys Workbench顯示動力學(xué)模塊,對平臺與船舶碰撞進行模擬研究;通過對船舶初始狀態(tài)的設(shè)置,使其以不同速度、不同角度與平臺樁腿發(fā)生碰撞以及在平臺不同作業(yè)水深時與樁腿碰撞,對平臺進行碰撞響應(yīng)分析,分析平臺危險部位;計算平臺遭遇到供給船和守護船撞擊的頻率,提出降低風(fēng)險措施。
[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.
