To provide a pneumatic fender whose diameter is capable of being greatly enlarged during use compared with when it is not being used, such as during storage, transport, and the like. The body portion 2 is configured by laminating a plurality of reinforcing layers 5 between the inner layer rubber 4 and the outer layer rubber 7, the cords 6a, 6b of reinforcing layers 5 that have been laminated adjacent to each other intersect and are arranged at a predetermined cord angle A with respect to the body axial direction, an intermediate rubber layer 8 is interposed between each of the reinforcing layers 5, in an uninflated neutral state the thicknesses of the intermediate rubber layers 8 are 1 mm to 5 mm, and the cord angle A is set to 15° to 45°, so when the interior of the fender 1 is filled with air to the prescribed internal pressure, the cord angle A increases to a static angle while the intermediate rubber layers 8 deform in shear, and the body portion 2 increases in diameter and inflates.

A computer 11 of a ship monitoring device 1 arranges one kind of transmission data between two consecutive start control codes and two consecutive termination control codes. The computer 11 also arranges information indicating a type of the transmission data between the transmission data and the start control codes and between the termination control codes and the transmission data. In this way, the transmission data is transmitted in form of packet data. Therefore, transmission data in information communication between ships and sensed information in information communication of fenders can be easily distinguished from each other. In addition, a type of information transmitted as the transmission data can be easily identified.

A method and a system for assisting steering and mooring alongside of vessels that enables operators to easily obtain physical relationship between two vessels and the states of mooring lines and fenders when the operators lay the two vessels aboard and moors them alongside for loading cargoes are provided. Physical relationship between a hull of the first vessel (1) and a hull of the second vessel (2) is calculated in the form of numerical data based on information on a reference position of a first vessel (1) that is detected by a first GPS receiver, information on a reference position of a second vessel (2) that is detected by a second GPS receiver, oscillation information on the first vessel, oscillation information on the second vessel, information on a distance between the two vessels that is measured by distance measuring device, coordinate data including hull outer shape and the like against the reference position for each vessel, and air pressure data for each fender. Information on the physical relationship between the hull of said first vessel (1) and the hull of said second vessel (2) based on the numerical data and the state of each fender are displayed on a first display device provided for a steering room of the first vessel and a second display device provided for a steering room of the second vessel by means of animation.

Provided is a pneumatic fender that suppresses damage to a flexible hollow body and an energy-absorbing body and exhibits improved ship sway reduction effects. A pneumatic fender is provided with an orifice (10) that allows for communication between an interior space (4A) of a flexible hollow body (4) and the interior space (7A) of the casing (7), and a safety valve (8) that opens and allows for communication between the internal space (4A) of the flexible hollow body (4) and the internal space (7A) of the casing (7) by opening when the internal pressure (P) of the flexible hollow body (4) reaches a predetermined pressure (P1).

Numeric values "a" representing a respective order of transmission by a plurality of transmitting units, and a numeric value N representing the total number of transmitting units, are set for each of the transmitting units. At startup, a transmitting unit 100 for which the numeric value "a" representing the order of transmission of the unit itself has been set to 1 sets a trigger value to N and transmits information about the numeric value "a" of the unit itself and detection information input from a sensor portion; and, when the numeric value N is detected from a received signal, transmits the numeric value "a" of the unit itself and detection information. When a numeric value of a-1 is detected from a received signal, the transmitting unit 100 for which the numeric value "a" representing the order of transmission of the unit itself has been set to a number other than 1 transmits the information of the numeric value "a" of the unit itself and detection information.
