...Detailed Field Assessment A detailed field-based assessment of dynamic strain was carried out in order to understand the affect of process changes on weld dynamic stress and to provide input data for the fatigue life assessment. The assessment was broadly completed as follows: Step 1...

... Abstract During the construction of pipelines for the transportation of oil and gas, the inspection of girth welds is a critical step to ensure the integrity and thereby the safety and durability of the pipeline. In this paper we present an advanced technology ‘IWEX’ for the non-destructive...

... includes the qualification to sour service resistance under 6.84bar H 2 S of the base material and the welds without post weld heat treatment. Fracture toughness tests under 6.84bar H 2 S were also conducted, and the results fed into an Engineering Criticality Assessment (ECA) to define the Non-Destructive...

... explored alternate repair strategies, leading to the development of the DCN-patent pending µ-Habitat welding system. The µ-Habitat makes it possible to respond quicker, execute subsea repairs faster and guarantee quality at a fraction of the cost of bespoke or modular habitats. Through size reduction...

... It was the first time to use a ceramic shoes by Installation contractor, which leads to no previous experience. During the welder training onboard the vessel and preproduction weld we noticed that sometimes the ceramic coating have been damaged and debris have been in direct contact to the weld...

... their proprietary software tools to analyze the inspection data. The data contains signatures from the inspected pipeline. A skilled analyst with the help of the software tool is able to classify the signatures. The classification is divided into known features of the pipeline like weld, magnetic marker, sleeve...

... Many factors affect the flaw sizing accuracy such as probe positioning with respect to weld centre line, scanning speed, pipe band position, scanning surface condition, temperature etc. for which it is essential to study the uncertainties that will have effect on project specific acceptance...

...Data Filtering Artificial intelligence can be used to filter through huge amount of data to find the location of possible problems. This capacity can be used for many purposes. It can be used to look for geometry indications like the weld root, cap signals or the surface of the part. It can...

... insulation resistance. Chemical compatibility testing was performed on a number of metallurgies using a modified NACE H 2 S Sulfide Stress Cracking test based upon ANSI/NACE Standard TM0177. H 2 S test coupons of the various metallurgies were welded and formed, for testing of the tubing. The test coupons...
