Full-life Cycle Optimization Model of the Offshore Jacket Platform

摘要

In this paper, the full-life cycle optimization model of offshorejacket platform is proposed based on the work environment andstructural property. The initial investment, maintenance cost and failureloss cost are unified into the model. In the full-life cycle model, the totalcost of the jacket platform structure system in its full service period istaken as the objective function and the initial reliability vector of thelayer elements partitioned in advance is taken as the design variables.Different full-life cycle optimization models can be obtained withrespect to considering the system reliability constraint or not.
