Project

Makeni project consists of a sugarcane estate, a bioethanol refinery and a biomass fuelled co-generation (electricity) plant.

The plant will supply green electricity and heat to the bioethanol plant from the sugarcane biomass, and generate 120 GWh per year for the national grid, representing approximately 20% of Sierra Leone's needs of electric power. The plant reduces greenhouse gas emissions by 56.000 tCO2 per year through the replacement of fossil fuel-intensive electricity production.

Assignment
SECO's assignment consisted in the assessment of the structure of the main buildings of the plant, the storage tanks and the conveyors.
We assessed the stability of the foundations, the design of the concrete and mainly steel superstructures. Service loads, fatigue and seismic conditions were taken into account in our own calculations for validation.
Visits on site were carried out during the works in order to assess the construction process, the conformity to the drawings and the quality of the execution.
