Abstract: 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.

Abstract: A fastening assembly of a fire door to a bulkhead includes a shaped frame, to which is hinged the door, which includes a first bracket facing at least in part a first side surface of the bulkhead, and a primary flange, mechanically connected to the first bracket. The fastening assembly has a subframe, which in turn includes a second bracket, parallel to the first bracket and facing a second side surface of the bulkhead, and at least one secondary flange, mechanically connected to the second bracket. At least one joint mutually connects the frame and the subframe, to retain the bulkhead between the first and the second bracket mutually facing, without engaging simultaneously the bulkhead the portion of the first bracket facing the first side surface and the portion of the second bracket facing the second side surface.
