(Commercial Lease
Version)
Need:
Increasingly, multiple pipelines are utilizing the same
right of way with overhead power lines causing pipeline
cathodic protection systems to function improperly. Improperly
functioning pipeline cathodic protection systems result
in possible accelerated corrosion of the pipeline, increased
maintenance and repair costs and reduced integrity and safety
of the pipeline. There has been an industry wide, growing
need for a user friendly computer program that would assist
the user in predicting and mitigating inductively coupled
voltages on buried pipelines paralleling high voltage electric
power transmission lines.
Result:
The PC based computer program includes comprehensive electromagnetic
coupling equations with a very easy to use interface format
to enable both steady state and fault induced voltages and
currents to be calculated for up to three (3) un-bonded
pipelines co-located with up to ten (10) power transmission
line circuits. The program also has been enhanced analytical
capabilities including pipeline bond connections and pipeline
grounding capabilities for both steady state and fault current
mitigation. Unlike previously available inductive interference
computer programs, the format developed for this program
makes many of the computational functions and much of the
data input automatic for the user, thus leading to considerable
simplification in program usage. For example, data input
for only three computer screens are required to exercise
the program fully, i.e., one screen each for steady state
induction predictions, fault current induction predictions,
and mitigation design. This extremely simplified interface
makes the use of the program viable for a greater number
of potential users in the pipeline community than other
available programs.
Benefit:
The time and costs for investigating AC coupling problems,
inductively coupled interference studies, new cathodic protection
(CP) design with close or crossing competitive pipelines
with existing CP systems or overhead power transmission
lines, right-of-way and integrity planning, etc. is greatly
reduced with use of the program. The program can be used
by in-house pipeline operating staff or contract consultants
drastically reducing engineering time and costs while improving
the safety and integrity of CP design.
