ROSEN’s integrated approach - providing inspection, integrity and engineering - is capable of fulfilling the requirements of MAOP (maximum allowable operating pressure) validations comprehensively and holistically.
It consists of three complementary activities that cover all aspects of MAOP calculation and validation: Review and alignment of data, utilizing existing ILI data and the determination of pipeline properties with the new ground-breaking inspection service RoMat.
ROSEN’s integrated approach will fulﬁll all requirements of MAOP validation comprehensively and as a whole.
THREE COMPLEMENTARY ACTIVITIES
REVIEW AND ALIGNMENT OF EXISTING PIPELINE INFORMATION
Clients receive a comprehensive review and alignment of records (e.g. as-built drawing, pipe books, mill certificates, hydro test pressure records, etc.). Pipe information is digitized and incorporated into a structured format for a pre-existing or new GIS/IMS database.
UTILIZING EXISTING ILI DATA ROSEN can perform extended data analysis routines and processes on conventional ILI technologies. This gives our client new and in-depth information related to the pipeline properties and categorized into classes. The new view on existing ILI data provides a pipeline DNA.
ROMAT USES NOVEL ILI TECHNOLOGY FOR PIPE GRADE DETERMINATION
ROSEN’s innovative material characterization service RoMat assists the operator and provides an assessment of the yield strength of each pipeline joint. This measurement is closing the gap of existing pipe propertys methods. The high-resolution approach provides unique information along the entire pipeline irrespectively of the accessibility from above ground.
All gathered information is prepared for easy integration into a geographical information system (GIS) and to be further processed in an integrity management system (IMS). A comprehensive alignment of records is provided. The pipe line and pipe property information can then be further processed in an asset integrity management system (AIMS) such as ROAIMS.
MAOP is a fundamental parameter for further integrity assessment exercises, including defect assessments and quantitative risk exercises. Formal requirements in confirming MAOP for high-risk locations, such as high consequence areas (HCA) and moderate consequence areas (MCA), will define future processes to confirm or re-confirm MAOP. The novel Integrated Approach oﬀers MAOP validation at it's highest confidence.
