PSA probes drill floor incident on Valhall jackup
The Norwegian Petroleum Safety Authority will investigate an incident involving dropped objects that occurred last Sunday on the jackup Maersk Invincible.
OSLO, Norway – The Norwegian Petroleum Safety Authority (PSA) will investigate an incident involving dropped objects that occurred last Sunday on the jackup Maersk Invincible.
On the drilling module two swell packer stands came loose from the fingerboard, slid from one side of the derrick to the other and ended up in a gangway. Each of the stands, made up from lengths of drill pipe, weighs 1 metric ton (1.1 ton).
No injuries were reported, but a PSA team is traveling to the rig for the investigation. Their main objectives will be to clarify the course of events, describe the actual and potential consequences, and identify direct and underlying causes for future experience.
On a more positive note, the PSA has given Aker BP permission to transfer operation of the control room functions for the Ivar Aasen field in the central Norwegian North Sea from the platform to an onshore control center.
The relocation complies with the plan for development and operation (PDO) approved in 2013, which states that the field should be capable of control from a central control room on land. The transfer will take place shortly.
The consent covers the production facilities and associated wells, the subsea installations and their associated wells, infield pipelines, the oil loading system and gas export pipeline.
Draugen is an oil field situated roughly 150 km (93 mi) north of Kristiansund. Production started in October 1993 through a fixed concrete platform with an integrated deck, with deposits in the area produced by subsea wells tied back to the platform.
