Project:

ALE’s expertise has been put to the test when performing the load-in of the 7,000t Janice A FPU in an extremely tight timeframe in Norway, making this Europe’s heaviest decommission load-in operation by SPMT.

The timing was critical as the client had a specific deadline to meet which would impact on the overall project schedule. In order to meet this, ALE performed all of the required engineering in just two weeks and managed to mobilise a huge amount of equipment, including 267 axle lines of SPMT, to Norway in just 9 days.

The Janice pontoons, which was part of the old rig that was being decommissioned, was located floating in the water in AF Offshore Decom yard in Vats, Norway. This was a challenge as the condition of the structure was unknown in harsh conditions. As a result, the best solution was to pick it up using a semi-submersible barge. It was towed to the quayside, where ALE went underneath the structure and used SPMT`s to pick up the pontoons onto the deck. With 300 axle lines of SPMT ALE loaded it in.

By performing the operation in this way, the complete manoeuvre was completed within seven hours and meant the client could meet the tight deadline.

“To mobilise our equipment and crew in such a short space of time demonstrates our efficiency and engineering expertise. The client was impressed with our performance, commenting on our safe approach to the operations and accuracy throughout. To make a complicated Project like this to a success, a close cooperation between AF Offshore Decom, BOA and ALE was extremely important” explained Paul Karlsen, Regional Manager – Scandinavia.
