Pipeline Integrity Solutions

HOW TO PREVENT PIPELINE LEAKAGE The three methods used to prevent gas pipeline leakage are (1).   Design and construction (2). Operation and maintenance (3). Education and training These methods are explained below (1). Design and construction a.     Specify the technical specification for each pipeline. b.     Ensuring good construction practices, such as hydrotesting prior to pipeline operation c.     Increasing the protective technology (eg. coating) to further protect the pipeline d.     During the pipeline design, there is the need to evaluate the geography, topography, and geology of the terrain surrounding the pipeline. Avoid seismic, earthquake zone, and areas prone to natural disasters like landslide, swampy, and rocky areas. Perform topographical and geological survey, aerial photography, etc. e.     Perform hydraulic studies and size correctly pump or compressor f.      Accurately size surge su

ADJUSTMENT OF GAS QUALITY To ensure that the gas does not interfere with the integrity (corrode or damage) of the pipeline or other appliances and also meet gas quality regulations such as       a.  Gas Safety (Management) Regulations, 1996     b. European Association for the Streamlining of Energy Exchange – gas, (EASEE-gas) For gas, that does not meet the specified gas quality regulation or specifications; I recommend any of the following measures should be accepted to assure the integrity of pipelines or other appliances. (1) Blending Gas quality adjustment within the network, known as gas mixing or blending. Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is specified and controlled. a.    Within networks not possible if risk of off-specification gas to customers b.    At beach sub-terminal possible-availability/security of supply (2) Gas treatment a.    Derichment of high Wobbe index ga

Design Parameters This section reviews the relationship between the following pressures - MAOP, MOP, design pressure, surge pressure and test pressures - which are to be considered during design. It determines the design parameters and provides definitions and guidance on the parameters identified. Design Pressure (DP) Sometimes known as internal design pressure, this is the pressure that is used in all of the stress calculations in the codes and represents the maximum internal pressure that the pipeline should be capable of receiving during its lifetime at the lowest part of the pipeline system. The design pressure needs to be considered closely with the MAOP, MOP and surge pressure (see below for definitions). Design pressures should not be set unduly high otherwise excessively thick pipe will be required. Design pressures for onshore gas pipelines have been limited in the past by practice or statute. The design codes vary in their maximum pressure, if stated, but a
