Dangote Private Jetty Lagos Nigeria
Project Overview
GeoStructure was appointed by Dangote Group to conduct advanced geotechnical evaluations for the construction of a private jetty at a port facility in Lagos, Nigeria. The project involved complex conditions, including strong currents, high tidal ranges, a combination of various marine/inshore structural elements, and varying subsoil conditions. GeoStructure’s role focused on understanding and optimizing the original design through 3D sub-structure interaction (SSI) finite element analysis (FEA), ensuring that stakeholders had confidence in the jetty’s performance under both service and extreme loading conditions.
Challenges
Solution Approach
3D SSI FEA Modeling
Employed advanced three-dimensional finite element modeling to assess the entire jetty system response, including pile-soil-structure interaction, seismic effects, marine currents, and ship impact loads.
Load Response Optimization
Simulated vertical, lateral, and impact loading to evaluate structural performance and system behavior under service and extreme conditions.
Value Engineering Options
Evaluated multiple options to optimize the piling arrangement, maintaining safety while minimizing material requirements and construction effort.
Forecast Predictive Modeling
Built forecasts of structural trends and service performance over time to ensure reliability prediction at both local and global levels.
