A subsea pipeline (also known as an offshore or submarine pipeline) is a that laid on the seabed inside specially constructed trench [...]

The present paper describes fuzzy logic simulation of shielded metal arc welding (SMAW) process to predict the Quality of weld joint. It describe the quality of weld joint & effect of welding current, voltage and welding speed on tensile strength of shielded metal arc pipe welded mild steel joints. An ERW Mild steel pipe I S 1239 of 6 mm thickness and 150 mm diameter were used as the base mater...

Several developments in the past have greatly helped to enhance ultrasonic detection and sizing. An important step forward was the introduction of Time of Flight Diffraction (ToFD), making sizing considerably less dependent of defect orientation. Optimized pulse-echo techniques, advances in transducer technology and software support combined with ToFD now enable the relatively high reliability ...

In this study, a techno–economic model was used to calculate the costs of CO2 transport and specify the major equipment required for transport in order to demonstrate and implement CO2 sequestration in the offshore sediments of South Korea. First, three different carbon capture and storage demonstration scenarios were set up involving the use of three CO2 capture plants and one offshore storage...

This study used a digital imaging technique (DIC) to obtain the strain distribution at various locations in undermatching X80 pipe girth-weld joints under uniaxial tensile loading. In addition, microstructure characteristics and deformation patterns different regions were analyzed by scanning electron microscopy (SEM). The results showed that there was heterogeneity between of welded joint. Str...
