Backfilling of Gas Pipelines
South Pars Gas Field Development Phase 20 & 21
The South Pars Gas Field Development Phases 20-21 project is instrumental in expanding one of the world’s largest natural gas fields, necessitating robust and reliable offshore infrastructure. Read more . . . Commissioned by IOEC, this initiative called on Delta Offshore Technology to perform backfilling operations for two critical gas pipelines, each equipped with a 4.5-inch piggy-back line for transporting mono ethylene glycol (MEG). By ensuring precise placement and compaction of approved materials, Delta Offshore Technology helped secure long-term pipeline stability under challenging offshore conditions, reflecting its commitment to quality, safety, and environmental standards in large-scale energy projects.
