The present study investigates road safety culture (RSC) as an explanation for this discrepancy by: (1) Comparing the road safety behaviours among professional and private drivers in Norway and Greece, (2) Examining factors influencing road safety behaviours. While Norway had the lowest road mortality rate in Europe in 2017, Greece had one of the worst road safety records of all EU-27 countries. Sensitivity analyses indicate that the consideration of the expected costs from accidental events significantly impacts the obtained solution, and that investments to reduce these costs may improve the overall cost-efficiency of an Arctic offshore drilling support fleet. Some of the obtained solutions are similar to corresponding real-life fleets, indicating that the approach works in principle. As demonstrated through case studies, the approach may help to find a range of cost-efficient fleet compositions. The approach applies an Artificial Bee Colony algorithm-based optimization procedure. The approach considers the combined effect of the expected costs of accidental events, the versatility of individual support vessels, and ice management. The approach studies the main types of duties related to Arctic offshore drillings: supply, towing, anchor handling, standby, oil spill response, firefighting, and ice management.
This article presents an optimization-based approach for sizing and composition of an Arctic offshore drilling support fleet considering cost-efficiency.
