PlanSea collaboration yields £6.5million saving for Nexen

A collaboration between Aberdeen-based software firm PlanSea Ltd and Nexen has resulted in a yearly saving of £6.5 million for the operator.

By applying software developed by PlanSea, Nexen were able to simulate 65 weeks of North Sea operations using different schedules of platform supply vessel (PSV) operations. The simulations demonstrated that significant improvements in fleet size and vessel utilisation were possible if operations were reorganised.

The innovative system, which was developed by an expert team at Robert Gordon University before being spun-out as a separate company in 2015, uses advanced algorithms to optimise vessel utilisation. Working with PlanSea, Nexen were able to reduce their North Sea PSV fleet from four vessels to two.

Jim Cargill, CEO of PlanSea Ltd said: “The ability to accurately identify feasible ways in which reduced fleets can operate and validate that in realistic simulation is a game changer. There is a tremendous opportunity for the industry to collaborate with shared PSV fleets, potentially taking 40% – 50% out of resource costs. In the North Sea that could mean continued viability for assets that are struggling to break even in the current environment.”
