DESCRIPTION |
Rock Jacket® is a system
that was developed to offer excellent mechanical protection
to the anti-corrosion coating and the steel pipe of onshore
pipelines with the lowest total installed cost, installation
time and environmental impact in the industry. Rock Jacket® is
a plant applied reinforced concrete pipe coating developed
for rocky terrain, rough terrain configurations such as steep
slopes and for road and river crossings. It has been designed
to be buried directly in blasted out rock trenches without
the use of other costly protective products and is ideal
for both small and large diameter pipelines. |
| FEATURES
AND BENEFITS |
Unique Mechanical Protection
Rock Jacket® is the only mechanical protection system in the industry that offers excellent protection to the anti-corrosion coating and the steel pipe from mechanical damage during pipe handling, transportation, field stringing, bending, backfilling and in-service use. Rock Jacket® is fully compatible with the most widely used anti-corrosion coatings in the market.
Design and Installation Flexibility
Rock Jacket® is the only mechanical protection system in the industry that has no limitations in terms of terrain configuration, trench material type and climate. It has also proven to be bendable to the requirements of all standard construction specifications without any non-standard equipment or additional effort on the contractor's side other than the use of oversized shoes and die on the bending machines for large diameters.
Economic Advantage
Rock Jacket® was developed to be directly buried in blasted out rock trenches. This lowers the total installed cost of protecting the pipeline against mechanical damage compared to the use of more expensive protective systems such as sand padding backfill, mechanical padding or field applied rock shield. Rock Jacket® reduces the costs associated with buying or renting additional equipment, with surplus rock removal and right-of-way costs as it does not need additional trench depth and width.
Global Availability
Rock Jacket® is available for projects across 6 continents. Beside its strategically located fixed plants, Bredero Shaw has unique portable plants that can apply the Rock Jacket®. The plants can be mobilized in a short period of time to meet specific project requirements and to significantly reduce pipe transportation and handling costs. Plant mobilization near the pipeline right-of-way can improve the overall economics of the project and qualify for in-country content requirements. |
