For more than a year the LV Aberdeen and LV Vlaardingen offices have been working together to provide logistics support for the refit of the Helix Offshore vessel ‘Seawell’. This culminated in the execution of the biggest single move within the project, which took place at Nieuw-Lekkerland on the Dutch canal system on Monday 22nd June. IHC had fabricated and completely loaded the main derrick on the quayside and we were challenged to move this unit in the upright position to the re- fitting yard at Flushing (Vlissingen) in Southern of Holland. Standing 37 meters high on a 12 m square base and weighing 500 tonnes this was quite an undertaking.
We employed the floating crane Matador-3 to work together with a pontoon barge to execute the move. Having safely lifted the derrick, the crane then manoeuvred to allow the pontoon to be berthed to receive the lift.
After several hours of sea fastening and welding, the pontoon sailed via the inland canal system for delivery to Flushing (Vlissingen) on schedule. On Wednesday 24th the complete the operation was done to the total satisfaction of the client.
