The scope covered flushing and cleaning of a long-distance deepwater oil export pipeline, supporting safe and compliant decommissioning and abandonment activities. Execution was delivered through a tightly engineered offshore plan designed to meet all regulatory and environmental requirements.

Under the scope, EnerMech delivered an integrated solution incorporating high-pressure pumping, hydrocarbon filtration, and vessel-based operations. Residual hydrocarbons were safely displaced from the pipeline, achieving verified hydrocarbon-free status in line with environmental standards.

Charles “Chuck” Davison, Jr., CEO of EnerMech, said: “This award from Subsea7 reinforces EnerMech’s position as a trusted partner for complex pipeline decommissioning projects. The scope involved technically demanding work in a challenging offshore environment, requiring proven capability, experienced teams, and a relentless focus on safety. We’re proud to have delivered this program through disciplined execution and close collaboration with Subsea7.”

Nuno de Sousa, SVP Energy Solutions at EnerMech, added: “Pipeline flushing and cleaning is a critical step in the decommissioning process and must be performed with precision. For this scope, we applied a fully integrated execution model, combining specialist equipment, strong project controls, and Gulf of Mexico experience. Our teams delivered the work safely, efficiently, and in full regulatory compliance.”

Engineering, preparation, and offshore execution were completed safely and in line with project requirements. The successful delivery of this scope marks a key milestone in the wider decommissioning program, demonstrating EnerMech’s capability to execute complex offshore pipeline cleaning projects safely and to specification.
