Protection system for ship loading having a cover system comprising: a. a universal cover adaptable to any size of holds of ships, supported by cables, preferably composed of naval polymeric material, and said cover being inflated by means of air blowers to pressurize air in an annular tube which delivers the air in each of the sections of the cover; b. set of guides coupled by attachment means, preferably magnetic, allowing attachement to metallic parts of the ship's deck to fix the said cables of support; c. a coupling and operation device, composed of a ring shaped structure, preferably made of steel with anticorrosion treatment, which comprises the fixtures and fittings required for the setting and operation of the protection system for loading of ships; d. tractor which is formed by the association of an explosion-proof electric motor, a gearbox, a lubricated rope spreader assembly, reel where the cables are packed, and a fault diagnostic system, which has its own logic and inductive sensor, said tractor being responsible for handling, lowering and collapsing said universal cover; e. monitoring and control system of the loading, equipped with a camera capturing tridimensional images, by means of laser, and a man-machine interface equipped with an industrial computer, which controls all operations of climb, descent and movement of the cover of the protective system for loading of ships; f. an electrical control system, comprising an electrical panel, in which are installed drives, controls of the servo motors and blowers, protective devices, such as breakers, fuses, power supplies, key counters, PLC and electronic control unit of the servo motors; characterized by a g. safety system against the action of wind, equipped with an anemometer, which measures the strength of the wind, and the operational limit of the respective equipment and sends the information to a manager program which, in turn, determines the range in which the equipment can operate, disabling it when wind loads exceed the operating limits; said protection system for ship loading can be adapted to the openings of the holds of ships through cables that run from the coupling and operation device and can be attached to said openings in the hold of the ship through locks, preferably magnetic, where said cable is pulled by tractors and still maintain a cover inflated, preferably made of polymeric material. a. a universal cover adaptable to any size of holds of ships, supported by cables, preferably composed of naval polymeric material, and said cover being inflated by means of air blowers to pressurize air in an annular tube which delivers the air in each of the sections of the cover; b. set of guides coupled by attachment means, preferably magnetic, allowing attachement to metallic parts of the ship's deck to fix the said cables of support; c. a coupling and operation device, composed of a ring shaped structure, preferably made of steel with anticorrosion treatment, which comprises the fixtures and fittings required for the setting and operation of the protection system for loading of ships; d. tractor which is formed by the association of an explosion-proof electric motor, a gearbox, a lubricated rope spreader assembly, reel where the cables are packed, and a fault diagnostic system, which has its own logic and inductive sensor, said tractor being responsible for handling, lowering and collapsing said universal cover; e. monitoring and control system of the loading, equipped with a camera capturing tridimensional images, by means of laser, and a man-machine interface equipped with an industrial computer, which controls all operations of climb, descent and movement of the cover of the protective system for loading of ships; f. an electrical control system, comprising an electrical panel, in which are installed drives, controls of the servo motors and blowers, protective devices, such as breakers, fuses, power supplies, key counters, PLC and electronic control unit of the servo motors; characterized by a g. safety system against the action of wind, equipped with an anemometer, which measures the strength of the wind, and the operational limit of the respective equipment and sends the information to a manager program which, in turn, determines the range in which the equipment can operate, disabling it when wind loads exceed the operating limits; said protection system for ship loading can be adapted to the openings of the holds of ships through cables that run from the coupling and operation device and can be attached to said openings in the hold of the ship through locks, preferably magnetic, where said cable is pulled by tractors and still maintain a cover inflated, preferably made of polymeric material.
