Handling of 560 wind turbine generator components for the Amakhala Project, South Africa
ALE was contracted to provide the handling of 560 wind turbine generator components for the Amakhala project in the Eastern Cape of South Africa. ALE were responsible for receiving the components at the Port of Ngqura, transporting them to a temporary storage and to site before finally offloading the components on site.
A total of 56 wind turbine generators needed to be delivered (excluding related accessories and containers). these comprised of 10 components each namely, three blades, one nacelle, one rotor hub, one drivetrain and four tower sections. the components ranged in weight and dimensions, with the longest blades transported to date by ale at 58.5m.
The components arrived by means of eight geared vessels in the Port of Ngqura, Port Elizabeth. ALE were the first company in South Africa to make use of a new laydown outside the Port of Ngqura.
Throughout the course of the project, ALE received the components and transported them from the finger jetty to a temporary storage facility in the port, before reloading the components for onward transportation. In order to handle the components, ALE supplied two mobile cranes and one telehandler for the port operations.
The components were then transported to the site located in Amakhala, Bedford, approximately 250km from the port. The 58.5m blades were transported by means of 3 x 4 axle lines of nooteboom axle quarto-extendable blade trailers. The nacelle, hub, drivetrain and four tower sections were transported individually on 7 x 8 axle lines of nooteboom single extendable trailers.
On the day of transportation, the components departed from the port of ngqura under the control of the police traffic escorts. The components travelled together in convoy consisting of 10 special abnormal load trailers, 20 ALE light vehicle escorts as well as the presence of the police escort to site.
Once on site, ALE offloaded the components using two mobile cranes and one telehandler with a rigging crew and site manager to oversee and coordinate the offloading operations.
The feed rate was to deliver two complete turbines per week, consisting of 20 components in total.
The project lasted approximately eight months.
