New! IPOZ Metrology 10
In association with our sister company STI, (the largest provider of seismic survey services in the USA), we can help you survey on land in any area or country, for exploration, production or any geographical reference need. Underwater we can help you design a navigation system for Remote Operated Vehicles (ROV) or a survey instrument to measure seabed structures and features, we can survey pipelines from the inside (pigging) and the outside (INS/Acoustic/DVL etc...), we can measure spools (metrology) or any point on any structure (in any orientation). Even within a crumbled underwater platform...
We offer the new Inertial Metrology method to the Offshore market. Between the pipeline network ending at a manifold and the well heads, a piece of pre-fabricated spool is introduced. Since it has to fit to extreme precision both in 3D position and orientation, the flanges are surveyed with care in a process known as seabed Metrology. Traditional Metrology methods such as acoustic network-gyro-bathy are slow, non-productive and affected by interference and multipath. We offer the new Inertial Metrology method where the full metrics are collected completely autonomously in 1 single ROV dive. The same equipment can be used for Riser measurements and pipeline out-of-straightness surveys.
With many years of experience in the pipeline survey business, we believe we offer the best methodology and the best deliverables of the industry. We will deliver accurate maps, GIS information, full report with position and orientation at up to 500Hz of every feature and defect observed by your pipeline pig. Well offer as a bonus a 3D visualization on Google Earth ("Fly Over"), with all geo-referenced information. Here also we specialize in the use of Inertial Navigation for the core positioning and orientation of the pig within the pipe. Contact us and ask for samples of our deliverables.
On land we offer a gamut of solutions where GPS and theodolites fail or are too slow and damaging to the environment. Our inertial survey instruments are the most accurate in the industry. Where GPS needs a clear open sky to receive satellite signal and radio corrections, and when the theodolite requires massive brush and tree cutting to obtain necessary line-of-sight, we can offer an environment-friendly and highly productive survey solution. Our GIPSI system allows us to obtain high rate, high accuracy land survey while walking between trees and shrubs, and therefore leave minimal damages and therefore guarantees low impact land survey at a low cost and maximal precision. For seismic receiver lines, we still cut straight lines, wide enough for the juggies carrying their cables, but with less damage and more productively than conventional survey techniques.
Sewer and Waterline Surveys
IPOZ offers complete 3D survey of centerline of sewers and waterline of all diameters. Automatic recording allows 1Hz to 400Hz density of information. All observed features (corrosion, cracks, welding, valves etc...) are also surveyed automatically or manually. Accurate maps and profiles are provided with full report. Accuracy 1m to 0.1m.
We have three types of inertial instruments for rental:
- Land Survey Units
- Pipeline In-Line Mapping Units
- Subsea Metrology Survey Units
- IPOZ GIPSEA™ Metrology unit rated up to 4000m depth. Surface software INSOne provides extensive real-time functionality as well as post-mission processing capabilities. Within 2-3 hours of diving, sub-inch accuracy can be achieved in real-time.
We can design the tool you need, in particular if the current technologies are failing you: can't use a theodolite in the sewers, can't use a laser to measure distances inside the water pool of a nuclear plant, etc. Need to know the exact distance between two seabed features with a structure in between?
Present us your problem and we'll tell you if we can solve it or not.
The personnel at IPOZ have over 100 years of experience in positioning and over 40 years in Inertial Navigation; we can consult for any new problem and situation. If we can't do it, we'll tell you before you spend a dollar.
