OFFSHORE PRODUCTION DECK RESTORATION WITH BELZONA
Industry: Oil & Gas (OILG)
Application: SOS-Ships and Offshore Structures (SOS)
Substrate: Carbon Steel
Customer Location: Gulf of Mexico, USA
Application Date: November 2013
Belzona 1121 (Super XL-Metal)
Belzona 9111 (Cleaner Degreaser)
Belzona 5811 (Immersion Grade)
Problem: Years of service without adequate maintenance in the offshore environment caused severe corrosion/metal loss of the production deck, impacting the structural integrity and personnel safety.
- Condition of deck before restoration.
- Installation of plate bonding system.
- Restoration of new plates complete.
- Two coat system of Belzona 5811 applied to new deck plates.
Total restoration of production platform deck using Belzona Cold Plate bonding system.
The deck area to be restored was cleaned and prepared by UHP/aggregate/rust inhibitors. Belzona 9111 was used as a wipe down to clean and degrease all areas. The Belzona Cold Plate Bonding System was installed using Belzona 1121 as adhesive. A two coat system of Belzona 5811/Aggregate was installed afterwards. The aggregate was used to create an antislip surface.
The asset owner had determined it would require 10-12 days of downtime to utilize the traditional welding process to lay down new plates with a production loss of US $ 350,000 per day. The comparison of welding materials/labor and Belzona plate bonding/labor indicated the latter to be about 20% higher. However, considering there would be no downtime/production loss with Belzona, the operator determined the entire materials and labor cost would be offset by one day of downtime, making an overall gain of over US $3 M.
