EnerMech completes ‘milestone’ pre-commissioning job in Gulf of Mexico

EnerMech says that it has completed a “milestone” pre-commissioning project for a major US energy infrastructure company in the Gulf of Mexico, marking the organization’s largest nitrogen membrane spread to be deployed to date in this geography.

The contract, first awarded in August 2023, was completed over an 11-month period and saw the business deliver its first ever 10,000 SCFM nitrogen spread in water depths of 8,800ft. 

EnerMech says that it provided a turnkey service covering the delivery of specialized services for oil and gas export pipelines for the midstream operator.

That included chartering three light construction vessels, coiled tubing and the design and fabrication of pig launchers and receivers. EnerMech says that the turnkey approach enabled their client to benefit from significant project efficiencies by eliminating the requirement to liaise with other third-party providers. 

Services for both the oil and gas export pipelines included flooding, cleaning, gauging, hydrotesting, and dewatering. 

EnerMech says that it deployed its in-house designed remote flooding console and subsea test pump to manage free flooding and hydrotesting at a water depth of 8,800 feet. 

In addition, multiple high-flow triplex pumps were utilized for hydrotesting the oil export pipeline. A single vessel was equipped for the 10,000 SCFM nitrogen membrane spread, which comprised 18 compressors, 5 nitrogen membranes, 7 nitrogen boosters, and 2 7/8-in. coiled tubing units.
