A GoM operator of a 6-inch subsea oil production flowline experienced severe paraffin blockage. The said deposition prevented a successful hydrocarbon de-inventory procedure in order to properly abandon the asset per compliance regulations. Due to insufficient pump rates, the operator faced expensive, complex subsea intervention tasks based upon routine flow assurance methods typically applied in decommissioning scopes of work.

A major midstream operator required decommissioning solutions for an aged gas pipeline asset. In order to properly abandon the said infrastructure in compliance with BSEE and state regulatory departments, engineering managers determined that an inert gas medium would mitigate several risks. As important, the asset contained a large amount of residual liquid product that required safe capture and disposal.

A Gulf of Mexico upstream operator required pipeline abandonment solutions for one 6 inch pipeline. The operator’s permitted Department of Interior (DOI) decommissioning obligation required a seawater flush volume equal to 110% of the internal pipeline capacity.

LiquiGell® pigs and de-oiling chemistry provide economic solution for multi-phase Gulf of Mexico pipeline decommissioning campaign.

BlueFin Model A manifold systems are designed for high pressure, multiple line flushing and pressure testing.
