Geotechnical drilling is a critical element for the construction of the Cabinda Plant, forming part of EPCM works assisting to determine the integrity of the site and determining the ground conditions for the design of plant foundations and footings.

The site investigation programme, which includes the geotechnical drilling and laboratory test work is being managed by GID Engenharia, an engineering inspection, consulting and projects company based in Cabinda.

The scope of work includes a review of the proposed granulation plant location and identification of any key areas of geotechnical risk, test pitting, including penetrometer assessments and construction materials suitability testing including PSD, CBR, Atterberg limits. The diamond boreholes are drilled to visually assess subsurface conditions, perform in-situ falling head permeability tests and obtain laboratory samples. The outcome from the Geotech programme will assist in finalising the foundation and earthworks design parameters for the granulation plant.

Fabrication of the granulator’s key equipment is now well underway with two of the three large drums required for the plant under manufacture at FEECO’s headquarters in Green Bay, Wisconsin, US.
