A Noble Corporation rig was damaged on Sunday at the Sembcorp Marine Jurong shipyard in Singapore.
Noble Corporation said the Noble Lloyd Noble sustained damage on February 28 after a shipyard crane boom operating near the rig collapsed.
An unspecified number of shipyard personnel also sustained minor injuries.
UK-based Noble said the damage appears to be confined to one area of the rig, including damage to one of the rig’s cranes.
The Singapore Ministry of Manpower has opened an investigation into the cause of the incident.
Access to the rig will be limited during the initial phase of the investigation, Noble said.
The rig is currently in the late stages of construction at the Sembcorp Marine Jurong shipyard.
Construction work was expected to be completed during the second quarter of 2016.
Following mobilization of the rig to the North Sea, the rig was expected to commence a four-year primary term contract with Statoil during the third quarter of 2016, with the contract stipulating a commencement date of no later than March 1, 2017.
Noble said that a thorough rig damage assessment will be required before a revised schedule of delivery and contract commencement can be determined.
