Before commencing the Inclination Logging
NOTE!
Before commencing the inclination logging, follow the on-
screen calibration instructions, ensuring this is done on a
reasonably level, at surface.
NOTE!
Inclination surveys are always best carried out in reverse,
after completing your survey.
Inclination Sensing
Some Proteus crawlers are tted with a sensor for inclination. The incli-
nation measures the “slope” of the pipe as the crawler is driving along.
The CCU, or a PC running suitable software applications (such as WinCan),
can log the values of the crawler inclination during the survey. From the
logged value, the CCU (or PC) can produce a graph showing the inclina-
tion slopes that the crawler experienced while driving along.
What inclination is for
Inclination is used to show the general trend in slopes within a pipe. It is
not for accurate measurement, and can’t accurately detect bumps such
as pipe joints.
Mainly it is used to look for signs of where there might be dips or peaks in
the pipe which could become water or silt traps.
Recommended Conditions for Inclination Logging
The quality of the inclination log depends upon many inuences. When
logging inclination, Minicam recommends the inclination is logged:
• in a clean pipe, so that the crawler does not lose traction
• when the crawler is reversing out of the pipe (to minimise
shaking due to the crawler pulling on the cable)
• at a medium speed, without stopping the crawler, after the
observation survey has been completed
It is possible to perform inclination logging when driving the crawler
forwards, though if the crawler is regularly stopped and restarted, this
will aect the inclination log quality.
