Takoradi is situated in the Gulf of Guinea. Ordinarily waves are 1.5 metres high, but in stormy weather they are another metre higher. To allow safe and continuous working, we first had to restrain the forces of nature.
Pascal Dumez, project manager civil works: “For the breakwater, we needed 2.2 million tonnes of rocks. Originally, we had contacts with one local quarry, where the quality of the stones was relatively good. But we need 14,000 tonnes of stone per day and also the specific rock sizes were problematic for them to achieve in time, the biggest ones had to weigh 5 to 7 tonnes each. Most quarries are not used to these high production levels and big rock sizes."
"Ultimately we worked with nine quarries and transferred our technical knowledge as to how they could obtain these large rocks and production levels. We even flew in an expert from an Ardennes quarry to show how with changes to drilling techniques, explosives use, charges and placement, the productivity and rock quality could be improved. After three such coaching interventions over four months’ time, they were able to produce the large rocks required.”
A project such as in Takoradi is very capital-intensive. Governments may well have the vision to expand their ports, often their budgets are inadequate. Mathias Van De Vijver, Financial Manager, explains how Jan De Nul can still realise these projects…Read more
The total quay wall height is up to 20.7 metres, with at low tide 3.2 metre above and 17.5 metre below water. It is built of 4,000 concrete blocks each of 50 tonnes, all made on site. When stacking the concrete blocks, these are aligned alternately.…Read more
The project in Takoradi started in 2012; today, it is almost 90% complete. Filip Morobé, Area Director Africa: “What makes this project special, is that there has been no call for tenders. The Ghana Ports and Harbour Authority (GPHA) has…Read more
Apart from wood, Takoradi mainly exports cocoa, bauxite and magnesium. The port is also the central pivot for all supplies to Jubilee Field, a huge offshore oil field west of Takoradi. Another part of the cargo entering the port is intended for countries…Read more
