The inspection process designed by the two companies helped identify critical points along the route and the company made adjustments to ensure the equipment could be transported safely. Melca Transporti worked with ENEL Green Power to conduct the path simulations. (Fig.5)Ĭhoosing the Vehicles, Simulating the Route with AutoTURN Through a range of speeds, from 5km/h to 20km/h, each iteration showed the swept path of the simulated vehicle matching the swept path of the field test vehicle accurately. The oversize vehicle geometry and the steering characteristics of each component have been reproduced in a plan and meets the guidelines regulating the automatic steering of rear axles of the semi-trailers in relation to the front truck axles (Fig.4). With the possibility of customizing the AutoTURN® library, defining the "vehicle type" and "ad-hoc" simulation profiles have been fundamental design aspects. The last ones are mainly common in Australian and North American regions (called "road train", combination of truck and 2 or more trailers). The software allowed ENEL Green Power to perform vehicle swept path analysis and simulate the driving conditions of the area.ĪutoTURN® includes a large selection of predefined vehicles, organized in international libraries and the software performs the simulation of "elementary" manoeuvres as well as of "simple" vehicles, trucks and special vehicles.
The aspects listed below are potential issues in the traditional approach, which is suitable for short routes and/or simple studies: They also tested the vehicle swept path of an oversized vehicle with an unloaded trailer. They measured the topography and the most critical curves along the route. Local engineering professionals were called in to inspect the overall topography of the route to assess any challenges. Moreover, it has been possible to identify possible adjustments to the existing infrastructure in order to safely operate the oversized vehicles. The actual tests have been set aside because they would have affected the road traffic and delayed the project schedule. The objective of the path simulation along the provincial roads SP 3 and SP 107 was to verify the priori conditions of the existing infrastructure. Two routes in particular: Strade Proviciale (SP) 3 and 107, from Reggio Calabria harbour to the project sites presented challenges to the engineers. The location of Piani di Lopa and Campi S.Antonio wind farm sites, which experts say are excellent for the wind and the rated power output, means engineers must study and plan the routes carefully prior to the transportation stage of the wind turbines components.ĭue to the conditions, use of specialized software simulating oversize vehicle paths is important for evaluating how the transportation of wind turbine components along the provincial roads might be achieved. They are mostly classified as "mountain roads", both for the geometric road characteristics and for horizontal curves of low radii.
The Aspromonte region infrastructure network has a limited number of paved roads. In Reggio Calabria, the ENEL Green Power project proposed 2 wind farms development to be constructed in two areas: Piani di Lopa with 14 wind turbines rated output 0.85 MW and Campi S.Antonio with 25 wind turbines rated output 0.85 MW, within the boundaries of the three southern Italian municipalities of Bagaladi, Montebello Jonico, and Motta San Giovanni.
With green technology like wind farms gaining popularity as generators of clean, efficient energy sources, technology and engineering are coming together to make these projects as safe and cost-effective as possible. Narrow mountain roads, steep hills and challenging ‘S’ curves are just part of the landscape in the ‘toe’ of Southern Italy, where wind farms are becoming a common part of the countryside.
