PPG SIGMASHIELD™ 880: Pertamina Refinery Unit IV, Cilacap, Indonesia

Pertamina IV

PPG SIGMASHIELD 880 enhances productivity while protecting jetty

The Customer

The Pertamina (PERSERO) Processing Unit RU IV in Cilacap, Indonesia has been in operation since 1976. This refinery boasts the country’s largest production capacity of 348,000 barrels per day.

Pertamina RU IV processes raw crude oil from the Middle East while simultaneously extracting lube oil and asphalt. It supplies between 34% and 60% of Indonesia’s national fuel needs.

The Challenge

Like many refineries, the Pertamina RU IV Refinery faces the major challenge of protecting critical refinery infrastructure from the ravaging effects of a coastal environment and corrosion. This is particularly difficult with jetty structures that are exposed to tidal zones, wave action, debris, on- and offloading activities, and the damaging effects of saltwater.

The coastal location of the jetty structure makes repair and maintenance even more of a challenge due to tidal limits on surface preparation and painting windows. Painting crews must therefore work quickly and efficiently to remove the old coating and corrosion, and begin repainting immediately.

The Solution

The PPG SIGMASHIELD 880 coating was selected because of its abrasion- and corrosion resistance performance, easy application characteristics and as it can be rapidly immersed into splash and tidal zones.

The PPG SIGMASHIELD 880 coating’s high-surface tolerance makes it ideally suited to withstand exposure to saltwater. Its rapid drying time was a key to the successful application at Pertamina RU IV. The coating was subjected to immersion within 30 minutes after application due to the tide but continued to cure without adverse effect.

Although the PPG SIGMASHIELD 880 coating is not reinforced, it still achieves the abrasion resistance that is important in this Pertamina jetty application due to the wave action and debris to which the pilings will be exposed.

Its improved cathodic disbondment protection provides enhanced corrosion resistance. Conclusively, the PPG SIGMASHIELD 880 coating is an excellent choice for a splash zone application in extreme environments, such as the tropical climate in Cilacap, Indonesia where the Pertamina RU IV refinery is located.

The Result

The maintenance and application of the PPG SIGMASHIELD 880 coating was completed within the constraints of this tidal zone, saltwater immersion and coastal environment.

Inspection of the Pertamina jetty 18 months after the maintenance and repainting with the PPG SIGMASHIELD 880 coating demonstrated superior corrosion and protection performance relative to the competitor product, which showed numerous areas of breakthrough rust and corrosion on jetty pile pipes.
