The customer is one of the leading natural gas processing companies in Dubai. Dubai Petroleum supplied the feed for the plant until 2011 when they stopped supplying feed for various reasons, which lead to the customer shutting down for an indefinite period. The Kanoo Group discussed with the customer the possibilities of corrosion occurrences while the plant is down. A series of presentations were made and they offered the customer a turnkey mothballing solution for long-term corrosion protection.
The total mothballing area estimated was 80,000 sq mt which included around 30,000 sq mt of insulated pipes and columns. The Corrosion Under Insulation (CUI) application, a major challenge, was achieved in the following way:
Half inch holes were drilled externally on the insulated surface at intervals of 1.5 meters.
VpCI®-658 was injected at 0.5 ltr per cubic meter.
The holes were sealed.
Clearly visible UV stable labels were applied on the outside with equipment details, preservation date, next inspection date, next preservation date etc.
With the help of a skilled team and good project management the entire project was completed within 7 months, much earlier than planned. Personnel at all levels within the plant appreciated the efforts of the successful completion and expressed satisfaction in the way the project was conducted. The Kanoo Group received an appreciation letter for their efforts. (Letter Attached)
