Noble Discoverer headed to Singapore
The drillship after already undergoing a lengthy upgrade programme in South Korea.
The Anglo-Dutch supermajor in January elected to call off a 2014 reboot of its mishap-filled 2012 drilling season after an unfavourable court ruling and exploration slimdown worldwide.
But Shell had already committed to a three-year deal for the rig starting in late February 2014 at a day rate of $368,000.
"After maintenance and upgrade project in South Korea, rig mobilising to Singapore in preparation for the client's future drilling program."
Neither Shell nor Noble immediately responded to a request for comment on the scope of the work.
The Discoverer had been in Korea under its prior Shell contract since March 2013 for maintenance and upgrades at a day rate of $244,000.
Upstream also previously reported that Shell had signed Transocean (RIG)'s semi-submersible Polar Pioneer to remain on standby in the event that a relief well or other measures were needed.
That unit is also booked on a three year contract at a rate of $620,000 during the July-October summer period and $589,000 during the off-season for the three years, according to Transocean fleet status data.
