Brazilian mining company Vale, the world’s largest producer of iron ore pellets, constructed a processing plant near the port to produce steel pellets for onward export. The import and export of materials meant that a new bulk iron ore jetty was required.
Royal HaskoningDHV was commissioned to carry out a reference design and prepare contract documents for the design and construction of the jetty. Our team then carried out the tender assessment and worked on-site to supervise the completion of construction works.
Supporting this massive structure was an interesting challenge. The approach channels and berthing pockets were dredged to 25m, requiring the removal of more than 8 million m3 of material.
The structure is supported by piles almost 2m in diameter. With the jetty being 10m above the low tide water level, the resulting length and thickness of the piles made handling and driving technically difficult. In total, some 500 piles have been driven.
