Problems solved by technology

[0009] Of course, a larger set of sensors than strictly required by the regulations allows to have a more detailed picture of the state of the ship's platforms and structures, but results in a larger overall size of the system due to the number of sensors, cables and hardware installed on the ship

Abstract

System for assisting the driving of a ship, 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 (40') 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 said magnitude at the predetermined point in the ship structure, compare said indication of magnitude with the estimate of said magnitude so as to determine an offset value, and correct the estimates of the structural loads and/or the estimate of said magnitude on the basis of said offset value.

Description

technical field [0001] The present invention relates generally to the fields of shipbuilding and navigation; more particularly, the present invention relates to a system for assisting in navigating a ship. Background technique [0002] Traditional structural monitoring systems include sensors that record the global and local structural stress states of the ship's structure, pressures affecting the hull, and rigid-body motions of the platform. [0003] It is sufficient to use a limited number of sensors, the associated acquisition hardware and software to meet the requirements of the register, to obtain additional class symbols for structural monitoring (symbol MON-HULL+S for RINA, MON HULL for BV, HM for ABS, DNV for HMON, HSS of Lloyd's Register). [0004] For example, regarding RINA's symbol MON-HULL, the following is sufficient: [0005] - 1 long reference strain gauge located on the centerline for measuring the bending strain of the hull girder; [0006] - 1 vertical ...
