DNV GL 5-year class renewal/SPS (Special periodic Survey)

About 75% of the scope has been carried out while the rig was in operation. The remaining scope was completed while the rig was at anchor. The idea of doing SPS over such a long period of time is to minimize the impact of needed downtime. No downtime was taken while in operation, we utilized existing time windows to complete the scope that could be done in operation. Putting skills of co-operation and planning to the test. But we managed on time and without any QHSE incidents.

Our key duties.
