Marine transportation industry and regular lines, in particular, have been increasing the last 20 years significantly. The increment of the
ships draft and the power of engines during the docking and undocking maneuvering is generating serious problems to harbors.
Nowadays, the present propulsion systems are closer to the soil of the docks with higher power engines, causing sediment erosion close
to toe of the docks which, in turn, may cause severe problems to the docking platforms. Moreover the eroded sediment is deposited along
the inner harbor reducing the water level and operative zones for several vessels maneuvering. Today, the equations used to compute the
future erosion are based both in theoretical equations with hypothesis far from reality and experimental studies using one helix as the
propulsion system. The docking and undocking maneuvers are the most effective in terms of erosion, in particular for vessels without the
help of a tugboat or pilot.
The project aims to evaluate the erosion caused by double helix stern propulsion systems varying the pitch and including the effect of the rudder.
The tools used to reach the main objective will the a maneuvering simulator, field obtained data, physical models at a
laboratory and finally the introduction of a numerical eulerian model.
The specific objectives are:
- To evaluate the in-situ effects of a vessel monitoring the docking and undocking maneuvering and its consequences on the soil erosion.
- To propose a new empiric equation to obtain the bottom velocity for a double helix propulsion system including the pitch and rudder
- To design new docking and undocking maneuvers in order to minimize the erosion cause by the propulsion system.
- To design new docking and undocking maneuvers in order to eliminate deposition zones using the effects of the propulsion system.
- To develop and validate a numerical tool to simulate flux evolution in rotational systems, free water surface and erosion caused.
