This study addresses a significant research gap related to hydrate formation in subsea gas pipelines, with specific focus on deposition rates during shutdown scenarios, which has received limited attention previous studies. Past employed various methodologies, including experimental, analytical, and computational fluid dynamics (CFD) approaches, predict conditions, but none have tackled the pre...

Slugging flow poses significant challenges to the offshore multiphase flowline and riser systems. Slug is characterized by an uneven regime whereby pipeline pressures, temperatures, or volume rates fluctuate. One of most common causes severe slugging low pressures which buildup fluid over time, consequentially pressure oscillations. This mostly occurs in vertical risers wells. The negative effe...

Transmission and distribution pipelines have a significant role in the oil and gas industries. Pipelines are facing different threat like corrosion, improper design and incorrect operation. Gas vapor released from a pipeline (owned by NIOC) failure spread out and reached to ignition source. Due to gas outdoor spreading, “flash fire” occurred and flame return caused “vapor cloud explosion” of ga...
