The present invention provides a system and method of side-stepping the need to retrain neural network model after initially trained using a simulator by comparing real-world data to data predicted by the simulator for the same inputs, and developing a mapping correlation that adjusts real world data toward the simulation data. Thus, the decision logic developed in the simulation-trained model is preserved and continues to operate in an altered reality. A threshold metric of similarity can be initially provided into the mapping algorithm, which automatically adjusts real world data to adjusted data corresponding to the simulation data for operating the neural network model when the metric of similarity between the real world data and the simulation data exceeds the threshold metric. Updated learning can continue as desired, working in the background as conditions are monitored.

A system assists the driving of a ship and is configured to estimate the structural loads of the ship due to the direct wave excitation, and structural loads of the ship due to the whipping effect caused by the wave slamming. The system includes at least one reference sensor adapted to provide an indication of a motion or stress magnitude at a predetermined point of the ship structure, and is further configured to calculate an estimate of the magnitude at the predetermined point in the ship structure, compare the indication of magnitude with the estimate of the magnitude so as to determine an offset value, and correct the estimates of the structural loads and/or the estimate of the magnitude on the basis of the offset value.

A floating structure for transport is presented, formed by a train arrangement of rotary bodies of revolution that reduces the drag of same during sailing, the train arrangement of rotary bodies being formed by a front body, intermediate bodies and a rear body that have rotation synchronized with the speed of travel of the structure, the intermediate bodies of revolution being connected together by longitudinal rotation shafts by connections secured to an upper platform, while the longitudinal rotation shafts of the front body and the rear body are connected to the rotation shafts of adjacent bodies by hinges, which are pivotably connected to an end of draft-adjustor, pivotably connected at their other ends to the upper platform, the longitudinal rotation shafts being disposed perpendicular to the structure's travel direction and associated with actuators. The rotary bodies are separated by a distance of approximately 5% or less of their diameter.
