PETRONAS Carigali (PCSB) is the owner and operator of an extensive network of sub-sea pipelines which are situated offshore from main land Malaysia, in the South China Seas. Many of these pipelines run from platform to platform and platform to onshore facilities over distances of between several hundred meters to several kilometers and in varying depths of water. Severe internal corrosion, due in large part to Sulfate Reducing Bacteria (SRB) has caused some of the pipelines to have a drastically reduced life span which has historically resulted in the replacement of pipelines becoming necessary within a time period as short as four years. Historically, there has not been a viable methodology that could be utilized to install such a corrosion barrier within a sub-sea pipeline, thus the project for the design and development of InField Liner? (IFL?) system was instigated and within three years brought to a highly successful conclusion incorporating the full rehabilitation of an 8" pipeline carrying Crude media and which was due to been decommissioned within six months had the installation not gone ahead. This particular pipeline is now fully anticipated to provide a further 25 years of operational use to PCSB. Robert A. Walters, IFL? Global Project Director and Chairman of Anticorrosion Protective Systems (APS), discusses the innovative InField Liner Technology, its offshore deployment within the PETRONAS pipeline network and the strategic plans for future global expansion. The company APS is a globally recognized pipeline rehabilitation specialist engineering and contracting company which is head-quartered in Dubai, U.A.E.
