New Port of Pointe Noire, Congo (Brazzavile)
Dynamic mooring analysis and downtime analysis for vessels operating in open sea with wave over 1.5m, period around 3s to 17s.
The Pointe-Noire Port Expansion Project is located approximately 8 km north of the existing port in Pointe-Noire, Republic of the Congo. This major infrastructure development comprises two 300,000-ton bulk ore export berths, one 100,000-ton potash export berth, two 50,000-ton multi-purpose berths, and a southern breakwater for harbor protection. Complementary onshore infrastructure includes storage yards, warehouses, logistics areas, and a production support zone.
To validate berth operability under environmental loading, HalcrowSea performed comprehensive numerical mooring analysis using the industry-standard Termsim II software. The simulations evaluated vessel stability under combined wind, wave, and current conditions, confirming the adequacy of berth layout and design parameters for safe operations.
Utilizing historical seabed topography, meteorological, and oceanographic data, HalcrowSea developed a spectral wave model (Mike 21) covering the project area and adjacent offshore zones. Continuous operational wave conditions from 1992 to 2006 were hindcast using OWI data to simulate long-term wave climates. Downtime analysis was conducted for 150,000 DWT, 200,000 DWT, and 300,000 DWT bulk carriers at each berth, with actual monthly and annual throughput hindcasted to validate design assumptions.
These advanced modeling and analysis techniques provided robust verification of the port's operational design criteria, ensuring the facility can efficiently handle projected cargo volumes while maintaining safety margins under challenging marine conditions, thereby de-risking the significant capital investment and optimizing long-term operational performance.
