随着海洋石油开发向深海进军,在海洋工程建造方面,导管架的建造也日益向大吨位、大跨度发展,陆地建造导管架的单片结构重量最大已经超过了1000吨,单台或两台吊机吊装已经不能满足施工需求,很多时候会采用3台以上吊机进行吊装。本文通过对4台不同型号履带吊机抬吊重达1153吨结构物中的各影响因素进行综合考虑,对该吊装的计算原则进行探讨,并采用海洋结构分析软件SACS对各台吊机分别达到极限工况时的结构物强度及其他吊机的工况进行分析,使得整个吊装计算过程更加完善,更好的指导现场施工,同时为今后大型钢结构的多吊机协同吊装计算方法提供了技术参考。
With the development of offshore oil industry entering into the deep sea, the construction of jacket has also been increasingly expanded to large tonnage and large span in the construction of offshore engineering. The weight of single-piece structure of jacked jacket built on land has exceeded 1,000 tons in maximum. One or two Crane hoisting can no longer meet the construction needs, often using more than three hoisting crane hoisting. In this paper, four different models of crawler crane lift weighing up to 1153 tons of the structure of the factors considered in comprehensive consideration of the principle of calculation of the lifting, and the use of marine structural analysis software SACS, respectively, to reach each crane The strength of the structure under extreme conditions and the working conditions of other cranes are analyzed to make the whole lifting calculation process more perfect and better to guide the on-site construction and to provide technology for the future hoisting crane hoisting method for large-scale steel structures reference.
