... increased to 177,000 BOPD when Maximum Allowable Working Pressure (MAWP) reduced from 1463 psi to 950 psi. This paper shows how to increase flow rates without reaching MAWP, two methods are recommended: loop the existing pipeline using a 406.4 mm x 56 km pipe. Use a drag reducing agent (DRA) to reduce...

... for design pressure as MAWP and accordingly adjust hydro test pressure followed by R-stamp requirements for rerating and repair. Shell side hydro test is restricted until recommendations are implemented Novel/Additive Information (25 - 75 words) Although conventional approach of replacing complete Shells...

... in the pipeline below its PP and still be breakable by applying pressure within the pipeline's Maximum Allowable Working Pressure (MAWP). Furthermore, the size of pipeline and the wax's natural insulation capability provides a radial temperature profile which can prevent the core pipeline from seeing a rapid...

... Abstract The Typhoon Field development required 9,000 psi MAWP flowlines from the four subsea wells to the TLP. An overview is presented of the design, manufacturing and installation of these four flexible flowlines. The flowline design required the use of insulation for flow assurance, start...

..." is currently in draft. It provides calculation examples of Maximum Allowable Working Pressure (MAWP), the maximum allowable operating pressure on an annulus, and provides flowcharts illustrating potential actions when sustained casing pressure is discovered. Company Requirements BP has several internal...

... vessels and piping), the calculation methods can be used to find a reduced Maximum Allowable Working Pressure (MAWP), and this paper is focused in find this information. The section has 3 assessment procedures levels, as follows: Level 1 assessment This is a simplified technique that does not account...

... to sustain a full wellhead shut-in. This inherently safer design practice ensured that the flowline pipe was specified with a maximum allowable working pressure (MAWP) equal to or greater than the maximum pressure expected to be produced by the well. This practice has been proven to provide adequate...

However, because the shear pressure at the 16 in. liner hole section MAWP was calculated to be more than 90% of the BSR operating...
