Abstract: Scheduling support vessels is a critical issue in the offshore oil and gas industry. This talk introduces a mixed-integer linear programming model for designing an optimal vessel schedule to complete prescribed cargo delivery and off-take operations. The model involves various constraints including vessel capacity constraints, base opening hours, and facility commodity demands. For real problem instances, solving the proposed mixed-integer linear programming model is extremely challenging due to its massive dimension. We will discuss heuristic procedures for generating an initial feasible schedule; this schedule can then serve as a good starting point for commercial optimization software packages such as CPLEX. Our experience shows that providing a good starting point is essential for solving large-scale problem instances arising in practice. We have applied the proposed optimization model to investigate real vessel scheduling scenarios in the Australian North West Shelf Project.
