Based on a connection matrix and a cost matrix, a mathematical model is presented to describe the optimization evaluation of the layout scenarios of subsea cluster manifolds in ocean engineering at the lowest cost. The connection facilities are considered, including jumpers, pipeline end terminations (PLETs), and infield flowlines. The dedicated series-iteration algorithms programed by MATLAB are conducted to solve this complex nonlinear 0‐1 programming problem. Additionally, numerical simulations are performed to demonstrate the validity of the model and the performance of its algorithms. The results show that the proposed model can precisely describe the layout characteristics of cluster manifolds in engineering and the dedicated algorithms are quite robust. Possible layout scenarios with three-to-eight cluster manifolds for 22 subsea wells can be obtained, from which the optimal one with the lowest cost can be found by comparison. This approach can provide quantitative and efficient references to engineers to assist them in making their decisions in the layout of subsea production systems.
