Iron ore marine bulk export terminal

New marine terminal facilities are needed at an iron ore mine in Brazil. Our navigation simulation studies supported the terminal design, and we also made recommendations to increase the operability of the facility. We confirmed wave conditions and mooring forces using a 3D physical model.

A new Capesize export terminal for Brazil

New marine terminal facilities are required at an iron ore mine in Brazil. The new terminal will comprise a loading pier in 18m of water depth to service vessels up to 220,000 dwt. The loading pier will be accessed via a 3.5 km long access bridge and the berth is to be protected by a breakwater approximately 650 m long.

Integrated navigation and physical tests

HR Wallingford carried out a series of navigation simulation studies to inform and support the development of the terminal design. We assessed the navigability of the terminal by ‘Capesize’ bulk carriers in adverse environmental conditions (wind and current).  The navigation studies also determined if the dredge footprint can be optimised;  and established the tug requirements and associated safe ship manoeuvring environmental operating limits.

We also examined extreme wind, wave and currents to estimate weather downtime at the berth and the maximum mooring loads.  This led to recommended improvements to the mooring arrangements at the berth that would increase the operability of the facility.  Wave conditions in the lee of the breakwater and mooring forces were then confirmed using a 3D ship mooring physical model.

Optimised navigation and mooring structures

Accommodating the navigation requirements of very large ‘Capesize’ ships brings special challenges, that have engaged our simulation and physical modelling facilities to the full. Our work has provided assurance that the new terminal will be navigable in extreme conditions. We have also helped our client to optimise the terminal design, reducing cost and increasing operability.
