Booms of two STS cranes, operated by TRP, extended in anticipation of larger post-Panamax vessels
Kalmar, part of Cargotec, has successfully completed the engineering of boom extensions on two ship-to-shore (STS) cranes operated by Terminales Rio de la Plata (TRP) at the Port of Buenos Aires, Argentina.
The project, awarded to Kalmar in January 2013, took just seven months to complete, with both cranes returned to full operation in August.
TRP, a DP World Container Terminal business, currently handles 800,000 TEU annually. It is now gearing up for the arrival of substantially larger container vessels, some with capacities of up to 18,000 TEU. This required the STS cranes’ boom geometry to be adapted and extended from 45 metres to 51 metres.
Extension of the boom was then undertaken at ground level which involved the welding of new interfaces, magnetic particle testing and ultrasonic testing inspections to confirm structural integrity and, finally, the reassembly of all the components before relocating the crane to its original quay position.
