The development of a robust hydraulic pan-tilt rotator is an integral part of the OASYS cable touchdown monitoring system. Designing such systems is a true mechanical engineering challenge: the system has to remain submerged in the splash zone for an extensive period and it has to withstand the effects of thruster wash while maintaining a 0.001 degree accuracy for object referencing.
Version 2 was finalised last year and achieved a 100% uptime performance during installation of the 44 Galloper cables. The new version includes a reduction in size and weight and a further improve in durability.
