Hydraulic Oil Jacking Rigs: Failsafe Reliability, Even in Brutal Conditions

Oil rig safety with punishing wind and seaoil rig birds eye view

Frigid North Sea conditions. Few settings demand as much from a locking hydraulic system. Our Bear-Loc® serves on hydraulic oil jacking rigs. Our most extensive installation was on a mobile rig, operated by GlobalSantaFe (now owned by another company).
Twenty-four Bear-Locs®, each with 650 ton locking capacity, were installed--six on each of the four legs—to assure that the platform remained safely positioned.  It’s mission critical. Human lives and the surrounding environment depend on the failsafe reliability of Bear-Locs®.

At the time it was the biggest mobile jacking rig.  Our last overhaul for this project was completed in 1996. The job requires a perfect service record: In fact, no rig using Bear-Locs® has ever toppled.

One of our engineers remembers this project and an unexpected high seas adventure.
“Safety is a high priority on rigs. I made multiple visits to the installation, overseeing the repair/overhaul. During one safety training, we were placed in a box with a window to simulate a helicopter, and dropped into a large pool, submerged and flipped upside down. We had to demonstrate that we could escape!”
