ILI Tool Support Services:
Tool Propulsion
Streamlined sourcing, reduced
project timeline, ease of schedulingand increased first run successFeatures and benefits

Baker Hughes, Process & Pipeline
Services (PPS) is the only company
able to provide best in class service
and equipment that will ensure firsttime right in-line inspection (ILI) andoff-line tool propulsion in one turnkey
package.
Intelligent pipeline inspections
provide the most sophisticated data
for the integrity of a pipeline systemand, in conjunction with hydrostatic
testing, are a fundamental part ofsafe operation. ILI tools are generally
propelled with pipeline product;but, occasionally, conditions exist
where another medium is needed for
propulsion, such as:• Pipeline is offline, idled,decommissioned or brand new• Normal operating parameters

are not ideal for ILI tool (pressureand/or velocity)• Product chemistry isincompatible or harmful to ILI tool
materials• Product temperature is above/

below ILI tool limits• Pipeline is dirty and requires

mechanical/chemical cleaning
ahead of ILI tool (multi-pigcleaning train)• Commercial or operational

constraints of certain mediums
may dictate water, hydrocarbon
liquid, compressed air or inert
gases as the propulsion mediumof choiceDetailed pre-engineering of therequired flows and pressures for eachindividual application is imperative.
PPS owns and operates proprietarymodeling software that accurately
simulates real-world pipeline
conditions. PPS Pre-commissioning& Maintenance group (P&M) has
developed this software over decadesof implementation, resulting in theaccurate prediction of the movementof smart pigs during gas and liquid
propulsion scenarios. By utilizing
customer supplied data, PPS P&M candesign a custom tailored solution
to provide optimal conditions fora successful first run, while also
minimizing the cost impact to you.
Providing turnkey service, including
engineering, project management,
and precise run parameters is ourstandard. We have the equipment
and personnel to manage tool
loading and extraction, lifting support,
tool propulsion, automated backpressure control, tracking, and tool
decontamination.
PPS can provide the solution thatworks best for you and the inspectionof your line.

• No disconnect between
pumping design parameters
and actual execution• A single project manager is
responsible for the overall
project from the initial tool
selection, launch, run, andtool retrieval to delivery of
final run data
• Overall goal for the infield
program is to gather the best
quality data for a reliableinspection report• No need to issue multiple
purchase orders• The use of multi-skilledcrews onsite, driving project
efficiencies

Additional solutions• Mechanical and chemicalcleaning• Separation• AGM tracking and tool
decontamination• Bolt torquing and tensioning• Nitrogen purging• Fluid pumping• Hydrotesting• Mobile flaring• Gas recompressionTypes of tool propulsion
NITROGEN (N2)
• Available in most larger populations areas; capableof high pressure/flow• Inert gases do not support combustion or interact
with pipe wall or ILI tool
• Venting to atmosphere does not require disposal

efficient cleaning• Water disposal may be difficult and costly plus

regulations vary by state/city• Air clean and dry required after dewatering on gas

pipelines

BATCH• Batch liquid will be propelled through the pipeline

WATER• Readily available• Allows for ultrasonic inspection• Incompressible fluids minimize speed excursions ofILI tool
