Odfjell Drilling, a 52-year-old offshore drilling player, has confirmed the wrap-up of a special period survey (SPS) for another semi-submersible rig that was on the agenda this year.

While disclosing the completion of the Deepsea Aberdeen rig’s SPS, the rig owner explained that the unit was returning to operations after three weeks of scheduled off-hire. This marks the end of SPS projects for the firm’s own fleet of rigs, with all four special periodic surveys reportedly completed on time and on budget, as well as with an average downtime below expectations.
