Abstract: PROBLEM TO BE SOLVED: To provide a wave height calculation device utilizing a ship radar, capable of calculating (estimating) precisely even the height of a small wave. SOLUTION: In this wave height calculation device, a wave number/frequency spectrum from which a noise is removed is generated from a radar image signal (step S101-S103), and an average wave cycle on an observation target region is calculated from the wave number/frequency spectrum (step S104), and a shadow ratio SR which is a ratio of the area of a shaded portion having a low intensity level to the observation target region area is determined from a reverse FFT result (radar image) of the wave number/frequency spectrum, and a significant wave height H1/3 is calculated from a relation; H1/3 =A.SRB using A and B corresponding to the average wave cycle (step S105).

Abstract: PROBLEM TO BE SOLVED: To eliminate scattering of dust sticking to the surface of a cutout conveyor to prevent explosion or ignition, and to extinguish flames quickly while preventing the spread of flames in case of fire.
SOLUTION: In a space 3 formed between a plurality of cargo holds 1 for receiving a bulk cargo C and a ship bottom 2, an air suction passage 9 connected onto a ship 6 is formed in the end of the opposite side to a vertical passage 7 connected onto the ship 6 that is formed at a prescribed part in a bow or a stern. There further formed a ventilation passage 10 communicating the suction passage 9, the space 3, and the vertical passage 7. The space 3 is partitioned into a plurality of sections for extinguishing flames by a plurality of fire shutter devices 13 capable of fastening the conveyor 5 having proper intervals in its cross direction and shutting water and air tightly.
