Typical Standards & Specifications
Concrete weight coating (CWC) is a plant-applied reinforced concrete coating system externally applied by using either impingement or compression (wrap) method to either bare pipe or pre-coated offshore pipe with a minimum thickness of 25mm, intended primarily for submerged service for water or oil and gas pipeline system.
The objective of a concrete weight coating is to provide required negative buoyancy to the pipeline, ensuring stability on the seabed, and/or to provide required additional mechanical protection for the pipe and its anti-corrosion coating during installation and throughout the pipeline's operational life.
