Obiettivo To lay a 12" flexible at 550m.At an earlier stage, we have fabricated a prototype and simulated on land the working conditions of the flexible.Hydrostatic crushing due to external pressureStatic acial tractionDynamic movementsA. To determine the resistance to collapse (55 bar) with the outer layer Pierced, the following material was utilised. Compression chamber Pressure delivery system Reduction in volume measuring system Measuring thermometreBefore being put into the chamber the flexible is filled with water and connected to the measuring system. While the pressure in the box is increasing, the flexible decreasing in volume expels some of the water which it contains. This water collected in a graduated cylinder gives the amount of volume decrease.B. To verify the tensile strength (160 t), the force corresponding to a flexible Submerged at 550 m, the following material was utilised:A tensile machineMeasuring apparatusThe sample was held at one on a fixed point of the bank bya ferrule, the other extremity was attached to the jack of the traction block.C. A study of the behaviour of a flexible laid on the bottom but not touching The soil and therefore exposed to cyclical forces by the currents was examined With the aid of a fatigue machine. The bending is given by the inclination of the jaws which hold the extremities Of the flexible, rotation is implicit in this arrangement.
