ABERDEEN, UK --MB Inspection has removed and replaced the top section of the flare tower on BP's Magnus platform in the UK North Sea.
Aker Kvaerner awarded the $812,000 contract earlier this year, following assurances that MB could safely and effectively remove 30 m (98.43 ft) of the 75-m (246-ft) steel tower, which stands 126 m (413 ft) above sea level, along with flare tips and vent lines.
An offshore team of 11 rope access technicians prepared the tower by disconnecting all wiring, un-bolting the sections, and removing the walkways. MB also used air hoists to lower discarded material, as there was no crane on the platform suitable for this task.
The crane onboard theSaipem 7000, stationed alongside the platform, then removed the tower, replacing it with a new section that had been fabricated onshore. This part of the operation was completed in under three hours. According to MB's rope access manager Paul Munro, although flare tip replacements are commonplace in the North Sea, this was the first attempted removal of an entire section of a flare tower.
