A crane boom has collapsed at Sembcorp Marine's Jurong shipyard in Singapore, injuring personnel and damaging newbuild jackup rig, the Noble Lloyd Noble.
The incident took place after a shipyard crane boom operating near the rig collapsed and damaged one area of the structure, including the crane.
Noble said that its rig Noble Lloyd Noble is in the late stages of construction at the shipyard.
An investigation is being carried out by the Singapore Ministry of Manpower to determine the incident's cause.
Access to the rig is limited as the investigation's initial phase is ongoing, Noble said.
The company expected to complete construction on the Noble Lloyd Noble during the second quarter of 2016.
The rig was planned to be mobilised to the North Sea to start a four-year primary term contract with Statoil during the third quarter of 2016.
Noble said in a statement: "A thorough rig damage assessment is required before a revised schedule of delivery and contract commencement can be determined."
The rig is capable of working in water depths of 492ft. It has variable deck load of 17,600 kips, a hook load of 2,000 kips and setback capacity of 1,800 kips.
