The incident occurred on mobile drilling unit Transocean Barents in connection with work on well 6305/7-5H D North on the Ormen Lange field.
Transocean Offshore Ltd NUF (Transocean) holds an acknowledgement of compliance (AoC) and operates Transocean Barents.
A roustabout was injured on 4 March 2015 while carrying out an inspection in the derrick. He was on a work platform about 12 metres above the drill floor, and was probably bending forward a little over the railing when the yoke for the top drive descended and snagged him.
The roustabout was squeezed/struck between the yoke and the work platform railing, but managed to twist free. He suffered injuries to his head, neck and back. The incident had the potential to cause serious injury or death.
The investigation team from the Petroleum Safety Authority Norway (PSA) started work on the unit on the day the incident occurred. In addition to conducting its own investigation, the PSA supported the police inquiry. Transocean also investigated the incident and had participants from Shell in its team.
Nonconformities identified by the PSA’s investigation relate to:
The PSA has asked Transocean to describe how it intends to deal with these nonconformities.
