Drones can help offshore logistics to improve safety, increase production efficiency, and reduce CO2 emissions. Drones will also be used in the development of new energy solutions on offshore stations. The aim is to see new logistics and support infrastructure, which will complement what we now have on ships and helicopters. Johan Castberg FPSO requires offshore drone logistics operations and for that purpose literature review on the history and types of drones is done to establish a multi-criteria system. Based on that multi-criteria system a drone fleet with different ranges and payload capacities is established. Keeping an eye on the advanced and upcoming drone technologies that can boost the use of drones in offshore logistics different power sources are discussed. To fulfill the objectives of offshore drone logistics in a pre-operational and operational phase different challenges have been discussed in this thesis project that includes type of logistics model in the supply chain, loading and unloading mechanisms with human safety and Environmental parameters, Operational and maintenance regime, and feasibility analysis of the implementation of drone logistics. All these pre-operational and operational phase challenges are discussed in detail and solutions to different challenges are proposed
