Halliburton Pipeline and Process Services has been involved in the pipeline construction industry for almost three decades and has amassed an extensive track record of projects from all over the world covering onshore and offshore, oil and gas, large and small diameter pipelines. In recent years, projects have expanded to include work in deepwater environments such as Brazil, Gulf of Mexico and the Philippines with unique new technologies being born from the extreme challenges posed from these deepwater markets.
Halliburton provides the complete suite of pipeline precommissioning and commissioning services under a single project management team in order to provide enhanced safety, quality and schedule performance on any project. The services available from Halliburton are as follows:
Halliburton can flood (or fill) pipelines of any diameter from 2 in. to over 56 in. over distances of hundreds of kilometers. Our filtration and chemical injection systems have the capability and flexibility to meet your project's most demanding requirements for water quality and treatment. Refer also to our SPU™ subsea pigging unit for details of our system that provides pipeline precommissioning activities without the need for diver intervention.

Proving a pipeline has not been buckled, dented or otherwise damaged during construction activities requires passage of a gauging tool through the pipeline. Halliburton provides gauging tools to meet your most demanding project specifications. In addition, Halliburton has developed unique technology that can be used in conjunction with conventional gauging tools to monitor the distance travelled, velocity and pressures to more accurately determine the location of any detected damage.

Halliburton provides controlled pressurization and monitoring of testing operations using equipment supplied from our fleet of specialized pumping equipment. Pipeline test pressure is typically held for a period of 8 to 24 hr with calibrated instrumentation recording both pressure and temperature throughout the test period. Refer also to our SHU™ subsea hydrotest unit for details of our system that provides pipeline precommissioning activities without the need for diver intervention.

Halliburton Pipeline and Process Services has developed unique technologies for use in the precommissioning and commissioning of pipelines as described below:
Umbilical Testing and Commissioning
The flushing, cleaning, hydraulic testing and electrical testing of all subsea control umbilicals is completed to a high degree of cleanliness in a safe and efficient manner.
SPU™ Subsea Pigging Unit
The SPU subsea pigging unit is the proven technology used to flood newly laid pipelines in water depths from 5 to 5,000 meters (16 to 16,400 ft.).
The SPU device filters, chemically doses, controls the flow and monitors the flooding/pigging operations without the need for an attendant vessel. This can radically improve the flexibility of project vessel usage during precommissioning activities.
The self contained unit can be left for extended periods subsea while other project activities are being completed.
SHU™ Subsea Hydrotest Unit
The SHU subsea hydrotest device is the proven technology used to test newly laid pipelines in water depths from 5 to 5,000 meters (16 to 16,400 ft.).
The SHU device filters, chemically doses, pressurizes and monitors the testing operations without the need for an attendant vessel. This can radically improve the flexibility of project vessel usage during precommissioning activities. The self-contained unit can be left for extended periods subsea while other project activities are being completed.
