The planned out-of-service period is 60 days, excluding transit time to and from the shipyard. Total budged yard stay cost is $90 million.
Work scope includes major drilling and well control equipment maintenance and re-certification, anchor winch upgrades, inspections, modifications and investments, with limited steel/piping replacement.
Songa says there has been a slowdown in the marketoffshore Norway this year in line with global trends, with oil companies letting options for drilling contract extensions lapse.
Since late last year Norwegian shelf operators have declined options for four semis in Norway. As a result several rigs will likely exit the sector soon.
The situation should improve from the second half of 2015 and into 2016 as a result of low net fleet growth, Songa adds, with various known new rig requirements already emerging.
