FREE SWIMMING INSPECTION SERVICES

Our high resolution Combination Inspection tools are available in diameters 3"-12" . They identify and record all pertinent pipeline data including hardware, girth welds, bends (angle and degree), metal loss defects and pipeline specific geometry such as ovality, dents and body wall changes. All pipeline features are then recorded with reference to pipeline location and clock position. Our I.D./O.D. discrimination technology is also included which allows defects to be identified with respect to the internal or external pipe body wall.

Onstream is proud to offer a single combination inspection tool that is one of the shortest in the industry. Our design makes it easy to use existing barrels and pig facilities which save time and money to your overall Inspection costs.

By Combining all our recording instruments into this short body tool we eliminate the need for you to make multiple inspection runs to gather the same data sets our tools do with a single run.

Onstream's high resolution Inertial Mapping Unit (IMU) solutions are available in all diameters 3" thru 12". The IMU provides pipe center-line mapping, and 3-dimensional coordinates for all features identified in the pipeline. This greatly enhances your dig accuracy up to 1 meter, and provides geographic locations for all features in your lines.

The High Resolution IMU is another leap forward for the pipeline Industry. We are extremely proud to offer the first proven 3" and 4" diameter IMU in both Free Swimming and Tether applications. The information gathered by this unit accurately locates and provides 1 meter accuracy for digs, which alleviates the need to chain from a known point and can greatly reduce costs when compared to digging in the wrong location. It also has the ability to map the pipeline and overlay other Geospatial data in a GIS format.

When combined in a series of multiple runs Onstream's IMU can identify and quantify pipeline movement and give invaluable information before a pipeline surfaces or shifts leading to rupture. This unit is placed in conjunction with our Combination Inspection Tool and run during the same time, greatly reducing time and money.

Onstream is proud to offer this innovative solution for Pipeline integrity proofing. Used in conjunction with a traditional plated Gauge tool, this device is able to identify, quantify, and provide locations of any possible restrictions in your pipeline that would negatively affect a Inline Inspection Tool.

A standard Gauge tool can only provide go-no-go results. It does very little to identify specific threat conditions that could be contained in a pipeline. It also is very subjective, leaving interpretation of the Gauge plates open to a case by case basis, and once a gauge tool is damaged it becomes useless for any other potential obstructions in that line. Onstream is taking the guess work out of traditional gauge tools by developing the Smart Gauge Tool.

This revolutionary tool uses our standard Geometry, speed, and distance telemetry the same way our smart tool does. We then are able to download and analysis that data to provide a detailed report concerning any restrictions found in your pipeline. This information is crucial in determining the corrective actions needed to allow a Inline inspection to proceed and gives a far greater advantage to any company trying save cost instead of throwing money at unknown restrictions.


BI-DIRECTIONAL TETHERED SERVICES

Our high resolution Combination Bi-Directional Inspection tools are available in diameters 3"-12" . They identify and record all pertinent pipeline data including hardware, girth welds, bends (angle and degree), and metal loss defects. All pipeline features are then recorded with reference to pipeline location and clock position. Our I.D./O.D. discrimination technology is also included which allows defects to be identified with respect to the internal or external pipe body wall.

Our Bi-Directional Combination Tether Tool was designed to provide an inline inspection option for the lines deemed "un-pigable" by tradition free swim standards. Our system uses Single Pass technology that allows us to record data on both the send and pullback of an Inspection. This naturally saves time and money and allows a far more aggressive inspection schedule.

Data is processed on site and a preliminary report is given within 24 hours after completion of an inspection. When your line is down timing is everything, and Onstream always delivers where it counts.

Onstream is now proud to offer an industry first Bi-Directional Caliper Tool. This tool gives pipeline specific geometry such as ovality, dents and body wall changes within the Bi-Directional apparatus and attaches to our Single Pass Tether Combination Tool for quick and efficient use of inspection time and resources.

DOCUMENT SUPPORT & FAQ

1What is the Maximum Distance an Inspection Tool can achieve?
With our Tether Technology we have achieved a line inspection of 5700 meters, however, this will depend on variables such as cleanliness, bends, elevation changes, wall thickness and product. A general rule of thumb is plan for an average of 3000 meters. Our Free Swim Inspection Tool has inspected lines as long as 300 miles long and required an inspection time of over 30 days.
2What do you mean by 1.5D Bends?
1.5D bends or "Tight Radius Bends" are illustrated in the following document Onstream Bend Examples (PDF) for your convience
3Where Can I find a Pipeline Questionnaire?
Please Click here for our most current Onstream Pipeline Questionnaire (PDF)
4How clean does the line have to be for a Tether inspection?
Our Tools our extremely robust at achieving a successful inspection with less than ideal line conditions. However, the greater the cleanliness of the line, the better chance of success.
5How long will it take to complete a Tether Inspection?
Our Tether Tools run at 70m/min, both directions and gather data sets on both the insertion and pull back.
6Do we need to have a straight alignment to the Tether truck for Inspection?
No, A sheave can be used if anchored to a suitable structure or piece of machinery (trackhoe, dozer ect)
7How do I get Pipe Verified by Onstream
Onstream has the capability to verify your recently inspected pipe, either by hand or 3-D laser scan. In order to properly prepare your dig outs before sending, please review Onstream Pipeline Verification Instructions (PDF) for further information.
