The nautical studies can be used to optimize existing ports, increase ship size or draft and to assess the safety of new operations.

In this example, we used 3 simulators to test new towing techniques for a large containership.

In an area with heavy traffic, the nautical simulations can be used to test the safety of simultaneous operations and to support the authorities to define the rules.

In this case, we intended to check how the passenger ferries would affect the traffic of large containerships.

TPN-USP can execute simulations of all types of STS operations: at anchor, at berth or underway.

In this example, a STS LNG operation with a yoke-moored FSRU is being tested.

TPN-USP can do simulations of multiple vessels operations. In this example, we have 4 vessels:

• DP vessel eqquiped with the real DP system (hardware in the loop)

• Tugboat with automatic winch control

• Conventional tanker

• FPSO (not manned)

Inland navigation presents particular challenges. In the Amazon rivers, the large convoys are subjected to strong river currents and cross large vessels, requiring traffic coordination and nautical studies.

In this example, we tested if the convoy transporting fuel could safely cross other convoys of vessels in critical areas of the Madeira River.

To maneuver a ship under extreme conditions (waves, currents, wind, tide variation) requires deep investigation using nautical studies and maneuvering simulations.

In this example, large bulk carriers navigate in a natural depth terminal subjected to strong currents and tide variation. The accurate definition of the tide window is crucial for a safe maneuver.
