Project Number: M-2000-002
Project Title: BNL Cast Iron Joint Detector
Project Start Date: 2001
Projected End Date: 2004
Technical Details: The
objective of TEMASU (Terrestrial Magnetic Surveyor)
is to provide the ability to locate cast iron
joints and other ferrous magnetic metallic pipeline
fittings, such as couplings, valves and drip-pots.
TEMASU does not employ technologies used by conventional
equipment, but it incorporates an entirely new
approach to locating metallic substructures. TEMASU
measures the perturbations caused in the earth's
magnetic field by ferromagnetic objects. The magnetic
field, being relatively constant, will compress
and deflect as it passes through a buried metallic
object. TEMASU will process these measurements
using mathematical algorithms and visually display
this information on a real-time map. The specific
objectives are to: 1. Locate buried cast iron
pipe bell joints non-invasively (no direct contact
and from the street surface); 2. Provide reliable
information on a consistent basis; 3. Determine
buried pipe location in real-time; 4. Ruggedize
the for field conditions; 5. Make it lightweight
and simple to use.
The TEMASU concept was developed by Brookhaven National Laboratory (BLN), Upton, New York. The project (originally funded by Con Edison and KeySpan) was approved by NYGAS for BNL to provide a field proven tool. Although the technology showed promise during the concept phase, it was unable to detect pipe and or joints in a variety of field tests. As a result of this, a decision was made to not continue this development effort.
