OSLO –The Petroleum Safety Authority Norway (PSA) has launched an investigation into a serious incident on the drilling rig Deepsea Atlantic.

During lifting conducted on Aug. 10, a length of conductor casing weighing roughly 7 metric tons (7.7 tons) fell about 6 m (20 ft) onto the catwalk. One person was standing on the drill floor about 6 m (20 ft) away, but was not injured.

This incident occurred while the rig, which is operated by Odfjell Drilling AS, was working for StatoilHydro on the Gullfaks South field.

The elevator opened while lifting the first length of 30-in. casing from its horizontal position on the catwalk to vertical, causing the top end of the pipe to fall.

Since the bottom end of the casing had not lifted clear when the incident occurred, the measured weight on the lifting block at that point was 3 metric tons (3.3 tons). The operation immediately ceased.

The PSA has appointed a three-member investigation team to clarify the sequence of events and identify the incident’s direct and underlying causes.
