ABOUT
IPOZ SM2® Inertial Module is a mapping module used in In-Line Pipeline Inspections (ILI) based on Inertial Navigation technology. It is the perfect mapping tool for all pipeline inspections (pigging) recording raw linear and angular motions at 400Hz. The IPOZ SM2® Inertial Module™ driving the SM2 is a tactical grade IMU that provides a direct measurement of linear and angular motions as the PIG travels down the line. A powerful embedded recorder stores the high rate data for post-mission downloading and processing.
By design the IPOZ SM2™ ILI module can operate in the most extreme pigging situations including high pressure, velocity and temperatures, and is meant to flow inside the pig, with the pipeline product usually.
APPLICATIONS
SM2 ILI Kit is perfect for
Capturing Pipeline Pig Inspection anomaly data
Mapping pipelines onshore and offshore
Offshore Out of Straightness surveys (OOS)
THE IPOZ DIFFERENCE
+ INPUTS
- Power: 9-36V, 12W
- Optional Odometer Pulses: TTL
+ OUTPUTS
After the survey, the raw data is sent to IPOZ for post processing and delivery of reports in Industry Standard formats (ILI reports, ASCII, SEGP1, DXF, DWG, SHAPE…)
+ KEY SPECS
- Vibration: Mil 15g rms, 20-20,000 Hz @ PSD
- Shock: Mil 90g, 6ms terminal sawtooth
- Power Mil-Std-1275A,
- Hours of operation: 240, or determined by batteries.
- Operation temp: -54C +71C continuous operation
- Angular range >1,000 deg/s.
- MTBF: >20,000h
+ POST-PROCESSED ORIENTATION ACCURACY
- 3D Orientation: less than 0.1 degree
- Solutions delivered typically at 1” or user defined intervals
+ POST-PROCESSED POSITIONAL ACCURACY
- Horizontal Position: less than 1m, better on request
- Vertical Position: less than 1m, better on request
- Recommended distance between AGM & Control Positions: less than 1 km
- Marker Accuracy: less than 0.1m
+ PRODUCTIVITY
The results of comparison surveys show that the accuracy of the 3D positions and orientations derived from the IPOZ SM2™ and ML1™ data are of the highest level in the industry. After post-processing, continuous 3D positions within 1m are the norm, and can be brought to the decimetric level by request. Orientations are typically 0.1 degree or less. To maintain accuracy, a control point is placed approximately every kilometer along the line to provide “ties”. Those tie points are precisely surveyed and often times occupied by a device called an Above Ground Marker (AGM) box, which gives exact timing information of pig passage in order to apply the tie position to correct the inertial error.
