Songa Offshore have yet another BOP headache on one of its new CAT D semisubmersible drilling rigs.
The offshore drilling company reported the news Tuesday via its latest fleet status report, stating that the company’s brand new Cat D Songa Equinox “experienced further unplanned BOP related downtime”.
Another BOP Headache For Songa Offshore
Songa Offshore didn’t elaborate on what the problem was, but noted the downtime of the Equinox ran from 22nd January to 5th February 2016.
The failure of the BOP comes only days after the drilling rig reentered service from what Songa are calling ‘weather related repairs’.
The repairs in question were connected to the rig’s dynamic positioning, which failed on 24th December last year during drilling operations.
The failure caused the Equinox to drift off location with the bit still downhole forcing the rig’s management to trigger the Emergency Disconnect System (EDS)- cutting the drill string.
The initial repairs were finished on 12th January, 10 days before its latest BOP issues, giving the Equinox an operational efficiency of 46%, after only entering service at the end of 2015.
Songa Cat D BOP
The BOP issues comes the same month as Songa reported similar issues with one of its other new CAT D rigs- the Songa Endurance.
Like the Equinox, the brand new Songa Endurance only entered service at the end of 2015, having been hired on longterm deals by Norwegian oil major Statoil.
The rig’s BOP also suffered a failure during final testing prior to drilling its first well. Again, much like its latest incident, Songa haven’t given any further insight into the issue.
As with the Endurance, the Songa Equinox entered a period of downtime for repairs, only reentering an operational state on the 5th February, giving the rig an operational efficiency of 11% for the month.
No details have been given to the cost incurred by the downtime, or by the operation involved of reattaching and removal of the damaged drillstring from the well.
Songa Drilling Rigs
In its January update, Songa also noted that its latest driller, the Songa Encourage was delivered on 16 December 2015, and is now on its way to Norway.
Songa also stated that its Songa Trym drilling rig has been cold stacked as it looks for further work, after its current contract was cancelled early.
