A major midstream gas transmission company required stress corrosion cracking (SCC) integrity assessment services by hydrotesting to remain compliant with regulatory specifications. The project consisted of a single 101.9 mile pipeline with both 24 inch and 26 inch diameter pipe. Significant environmental hazards were encountered from pipeline contaminants. Additionally, unknown to the pipeline operator, the pipeline contained a significant amount of debris.

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.

An operator of a mini-TLP experienced flow assurance problems in a subsea oil production flowline system. Operator knowledge and production history identified the issue as a paraffin blockage. Unsure of the blockage location and remediation method, several failed attempts at pressure cycling from the subsea and platform sides resulted in a mechanical remediation need.

A GoM operator experienced problematic pressure differentials over a period of time, ultimately resulting in a completely plugged 6” flowline. Heavy paraffin solids completely plugged the flowline and prevented the transportation of liquid product. Upon an evaluation of available remediation methods, an extended reach mechanical solution was selected.

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 midstream company required a Department of Transportation (DOT) integrity assessment on a 30-inch transmission gas pipeline. In order to meet federal compliance standards for continued gas operations, the operator elected to execute a hydrostatic pressure test between an existing compressor station and a mainline valve location.

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.

A major midstream gas transmission company required Stress Corrosion Cracking (SCC) integrity assessment services to remain compliant with regulatory specifications. The pipeline was installed in the 1970s and was located in an environmentally sensitive area with high stakeholder interest and visibility. Further increasing project sensitivity, the pipeline owner expected multiple ruptures during the hydrostatic pressure tests phase. In order to compensate for this risk, an extensive outage period was scheduled and communicated to all customers.

A GoM upstream operator experienced problematic pressure differentials. Over a period of time this resulted in heavy paraffin deposition and ultimately caused several pigs to become stuck in the 6” flowline. Upon an evaluation of available remediation methods, an extended reach mechanical solution was selected to remove the lodged pigs and properly remediate the paraffin deposition.

A GoM operator witnessed a leaking 6” pipeline. Upon repairing the visual leak and attempting to perform a successful hydrostatic pressure test a second non-visual leak occurred, ultimately resulting in extended production loss.

In order to perform a second assessment and bring production back online, the pipeline assessment required a 100% fluidpacked volume of seawater to ensure an oxygen-free environment.
