The rig locking system is hydraulically driven and can be configured to work with any rig jacking systems of the jack up rig to perform the rig locking and the load transfer operation. It is designed in compliance with the rules of ABS, DNV, BV, Lloyd's Register and CCS rules.

The rig locking system mainly consists of :
