The transportation of windmills depends on various parameters. From the logistic side, most of the logistics costs consist of transporting wind turbine blades, tower and power case with a gearbox and an electric generator. Other parts are not very big and transportation costs will be relatively low. Windmills of some manufacturers can reach 100 meters or more. Wind turbines get heavier, rotor blades are longer, and the tower components are larger. The wind turbine body can weigh 75 tons or more.
One of the cheapest modes of transport is water transportation.
However, this type of transport requires specialized knowledge, careful planning and precise execution.
At the planning stage, it is very important to carefully coordinate with the carrier and / or shipping company storage, loading and securing plan. And when performed by experienced surveyors or manufacturer representatives must closely monitor the entire process, and in case of the slightest problem, stop the process and request to fix the problem.
Mafitrailers on Ro-Ro ships satisfy all the requirements for safe loading and transportation of all parts wind power plants.
Turbines – devices used to convert the energy of steam, gas, wind water into mechanical work, intended for the generation of electricity. They stand out for their considerable weight and dimensions and transportation of turbines is not a trivial task.
When organizing the transportation of the turbine, the following factors are taken into account:
- The mafi trailer for the transportation of the turbine must be selected based on its carrying capacity.
- It is important to consider the load dispatch. In many cases, a mafi trailer with a low loading height may be required so that the height of the load on the roll trailer is within the height of the ramp opening along which the roll trailer is towed into the ship’s hold.
- The turbine must be securely fastened, its stability must be ensured on the mafi trailer.
- Conditions at the place of loading / unloading should allow the roll-trailer to freely enter or to leave the vessel.
These conditions are optimally ensured at the port berths where ro-ro ships are loaded.
There may be temperature requirements (due to sensitive electronics), even that condition can be met on a ro-ro ship.
Transportation of massive equipment (weight of the reactor vessel – about 300 tons, steam generator – 340 tons) is a complex logistic operation.
From the manufacturer’s site, the reactors frame and the steam generator are separately delivered to the specialized motor vehicles to the nearest river berth then go by water to the nearest deep-water port, and from there on universal ships around the world.
Over 14 types of equipment are supplied for NPP power units, including equipment of the reactor building: reactor plants, sets of steam generators, main circulation pipes, main circulation pumps, pressure compensation system equipment, tanks for emergency cooling systems and passive protection of the core systems, etc., as well as building equipment turbine hall: high pressure heaters, vacuum, condensate and feed pumps, equipment for separation and reheating systems of a turbine unit.
The reactor is a vertical cylindrical body with an elliptical bottom, inside of which the core and internals are located.
From above, the reactor is hermetically sealed with a lid with drives of mechanisms and organs installed on it regulation and protection of reactors and branch pipes for the output of cables of sensors of in-reactor control.
The cover is fastened to the body with studs. In the upper part of the body, there are nozzles for supply and coolant outlet, as well as branch pipes for emergency coolant supply when the circuit is depressurized.
To transport such cargo, you will need tramp shipping – irregular sea transportation that is carried out in random directions without a specific schedule, in which such vessels are used:
- Handysize: dry cargo vessels with deadweight ranging from 10,000 to 50,000 tons
- Suez-max: vessels whose characteristics make it possible to cross the Suez Canal with a full load. The deadweight of such a vessel is approximately 150,000 tons with a length of about 285 meters and a width of 35 meters. The maximum draft of such a vessel is 23 meters.
- Panamax: a vessel with a deadweight of up to 75,000 tons, which, when fully loaded, can pass the Panama Canal.
- Capesize: a vessel (usually a dry cargo ship), the dimensions of which do not allow passage of the Panama Canal.
