An investigation is being undertaken by BMT, Hythe, Southampton, to study the behaviour of flexible offshore structures under the action of waves and tides. This, known as the Compliant Cylinder Project, is jointly sponsored by Government, and the oil and gas industry. They enable the stiffness and natural frequency to be varied, the cylinder in made is six segments which can then be controlled by means of a hydraulically operated locking system.
The locking equipment situated between adjacent cylinders is illustrated in the photograph. His includes hydraulic pistons, cylinders, brackets, and clamp, all of which were produced from FERRALIUM 255 (UNS S32550, Alloy 255, DIN 1.4507, ASTM F61). This alloy was chosen because of its proven record of outstanding resistance to sea water, combined with high strength. The cylinder has been tested on the Christchurch Bay tower since last winter where wave heights up to seven metres have already been experienced.
