Africa: Maputo harbour

An engineering geological study of the entire seafront of the Maputo harbour, in Mozambique was conducted between 2013 and 2014. The investigation consisted of 132 rotary core boreholes to average depths of about 25 m; 8 piezo cone penetrometer tests (CPTu) were also conducted and 104 boreholes were drilled in 4 parallel transects on land and over water at existing berths while 28 boreholes and CPTu testing were conducted over water, at potential new berths. In soft material, continuous down-hole standard penetration tests (SPT) were performed. The Maputo Port Authority used the results of the investigation to inform engineering design of new berths and for the upgrade of existing infrastructure.
