NON-‐METAL PIPELINE AND RISER R&D

48 Quality Engineering Services to the Offshore Energy Industry

Operator: Petronas Location: Malaysia Water Depth: Shallow Water Year: 2011 – 2013 Background: Many different circumstances can lead to corrosion, one class of corrosion causes is called Microbiologically Induced Corrosion (MIC). Anaerobic Sulphate Reducing Bacteria (SRB) produce hydrogen sulphide, causing sulphide stress cracking. Internal corrosion due to SRB can result in the replacement of the pipelines as short as four years. One solution is to use non-metal pipe instead of non-liner steel pipe. DMAR Work Scope: •  Engineering supports include strength and fatigue

analysis through complicated FE modelling, on bottom stability analysis, weight coating design, installation and test procedure development.

INFIELD LINER INSERTED INTO CORRODED PIPELINE AND RISER (LIFE EXTENSION)

Microbiotical Induced Corrosion

Operator: Petronas Location: Malaysia Water Depth: Shallow Water Year: 2012 – 2013 Background: Anaerobic Sulphate Reducing Bacteria (SRB) produce hydrogen sulphide, causing stress cracking. Internal corrosion due to SRB can result in the replacement of the pipelines as short as four years. One low cost efficient solution is to insert plastic Infield Liner into the existing corroded pipe. DMAR Work Scope: •  Engineering supports include installation

procedure development and analysis, and test procedure development
