Thanks to the emergency response with a new high voltage switchboard from Siemens and Power Management system Delomatic 4 from Deif, the drilling rig Transocean Winner could continue its normal operation after power production was shut down due to fire.

Performed artificial respiration on rig after fire

During Christmas 2009 a fire struck the high voltage switchboard on board the drilling rig Transocean Winner while operating in the North Sea. The rig assumed emergency power and drilling operations were immediately suspended. Since the accident occurred in the middle of the Christmas period the situation became more complicated, and the Transocean management in Houston entered emergency mode.

Artificial respirationProject manager Kolbein Tjelle left the same day from GMC Elektro in Haugesund to the Transocean office in Stavanger. Tjelle’s solution was to give «artificial respiration» by temporary power production.

Diesel units were picked up by emergency freight from Norway and The Netherlands, transformers from Madrid, and switchboard containers from Deep Ocean. GMC Diesel and GMC Maritime assisted with the installation and operation on board the rig.

Very short down timeThe down time for Transocean Winner was minimal due to the close follow up from GMC Elektro, who also attained DNV approval.

– It was vital for Transocean to maintain rig operation, and the alternative with towing to shore would have shut down the rig for a longer period. GMC Elektro has in short done a tremendous job with the solution and installation, says Jarle Lerstøl with Transocean Norway.

The Transocean Winner continued operating during an emergency power shutdown, thanks to GMC.

Diving vessel Acergy Osprey was upgraded from DP2 to DP3, against all odds.

The rebuilding of diving vessel Acergy Osprey from DP2 to DP3 was basically impossible without a separate switchboard. GMC Elektro, however, found a solution that DNV fully approved.

Delivered impossible DP3 upgrade

When regulatory change required that dynamic positioning (DP) for the diving vessel be upgraded a few years ago, the shipowner faced a huge challenge with Acergy Osprey. This diving ship, which was in full operation for customers in the North Sea, was certified as DP2. It only had a single room for instrument boards, while an upgrade to DP3 required two separate rooms.

– The requirement was a DP3 certification, which sets strict requirements for backup systems that are physically separated in a different room, says Kolbein Tjelle at GMC Elektro in Haugesund.

Splitting the instrument panelsThe assignment was given to GMC Elektro, and 20 professionals were sent to start working on Acergy

Osprey. The job was described as «impossible» due to the construction of the ship, but GMC still managed to find a solution by splitting the panels.

– All panels had to be rebuilt completely, with fire separation and separation of onboard power systems, Tjelle says. All panels were connected to systems for early detection of fire, and extinguishing systems were mounted within all boards.

– The work took about three weeks before we could upgrade to DP3 and invite DNV to certify the changes, Tjelle says.

New assignment for OspreyThe successful upgrade from DP2 to DP3 made the shipowner able to take on further diving assignments with Acergy Oprey. GMC Elektro was later hired to refit the diving systems and to reterminate the ship’s umbilical - the lifeline between the boat and its diving bell.

During a subsequent planned maintenance project GMC Elektro detected that a number of ship plate switches had fatigue damage from extended use and strain.

– This is a typical problem that we solved by replacing old switches with new ones, says Tjelle.
