Drilling Operations Halted on West Navion

In connection with minor repair work in the derrick of the drill ship West Navion, cracks in the wire sheaves have been discovered in the hoisting system of the dual derrick set (Ram Rig). As a result of the findings, operations on West Navion have been temporarily halted.

It is expected that the halt will last for another 2-3 weeks before operations are resumed.

Maritime Hydraulics, the supplier of the dual derrick set, has issued a request to "All users of Maritime Hydraulics' Ram Rigs" to inspect all drilling units equipped with the dual Ram Rig.

Consequently, Smedvig will initiate inspection of the drilling rig West Venture, which is also equipped with the Ram Rig derrick set.
