A quantitative study by NEITI and OpenOil shows that in 10 years (2008 to 2017) Nigeria lost between 16b and 26b for. Productivity and cost estimators for conventional ground-based skidding on steep terrain using preplanned skid roads. The estimated cost benchmarks provide critical input for steep slope wine growers’ cost-based pricing policy. ![]() Strategies to reduce the cost disadvantage are outlined. Although estimated skidding costs were higher when the designated skid roads were used, the increased costs may be offset by a reduction in adverse stand and site impacts, and a reduction in the safety hazards often associated with ground-based skidding on steep terrain.Įrickson, Michael D. Under certain conditions, the transformation of manual steep slope sites into TTs can be a viable economic option. Productivity levels decreased while costs increased as the amount of winch line cable needed to be pulled to choke logs increased. ![]() Comparisons of productivity and costs were analyzed for an overland random access skidding method, verses a skidding method utilizing a network of preplanned designated bladed skid roads. ![]() Continuous time and motion study techniques were used to develop productivity and cost estimators for the skidding component of ground-based logging systems, operating on steep terrain using preplanned skid roads. ![]()
