Offshore Production Deck Restoration With Belzona

Industry:

Oil & Gas (OILG)

Application:

Ships and Offshore Structures (SOS)

Customer Location:

Gulf of Mexico, USA

Application Date:

November 2013

Application Situation:

Total restoration of production platform deck using Belzona Cold Plate bonding system.

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.

Products:

Belzona 1121 (Super XL-Metal)

Belzona 9111 (Cleaner Degreaser) 

Belzona 5811 (Immersion Grade)

Substrate:

Carbon Steel

Application Method:

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.

Belzona Facts:

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.
