Monitoring and reliability study on structural elements at Onne Port Extension using non destructive method

Abstract

A reliability and failure monitoring study was done to ascertain the durability of Onne port extension in order to achieve the expansion and rehabilitation intention of the Nigerian Government. A non destructive method of structural adequacy test method using the Schmitt hammer test was done to ascertain the structural integrity of the members using rebound value scheme. The upsurge in materials and human activities due to Onne port as an acclaimed oil and gas free zone area have necessitated the construction of additional berthing facilities, a massive reinforced concrete diaphragm walls at both the front and the back of shores measuring (1300mm x 2600mm) and (1000mm x 15250mm) widths and depths respectively and is tied at 1000mm intervals with 80mm diameter bars. The diaphragm walls numbering 6912 staggered 500mm, mortar vireo pile of differential lengths, Stabilization Island compacted at 95% of maximum dry density with a 250mm thick reinforced concrete slab as quay deck were tested. The need to standardize the facilities in the port is to meet international best practice
