1. Which federal agency regulates pipeline safety in the United
States?
A. EPA
B. OSHA
C. PHMSA
D. DOT
PHMSA (Pipeline and Hazardous Materials Safety
Administration) oversees pipeline safety regulations in the U.S.
2. What is the primary goal of a Pipeline Integrity Management
Program (IMP)?
A. Reduce labor costs
B. Prevent leaks, ruptures, and failures
C. Increase pipeline throughput
D. Enhance marketing
The main objective of IMP is to ensure pipeline safety and
prevent incidents that could harm people, the environment, or
property.
,3. Which type of pipeline is considered high-consequence areas
(HCA)?
A. Pipelines in rural areas
B. Pipelines in deserts
C. Pipelines in populated or environmentally sensitive areas
D. Offshore pipelines
HCAs are areas where a pipeline failure could have significant
impact on human life or the environment.
4. What is the most common method for detecting pipeline
corrosion internally?
A. Hydrostatic testing
B. Visual inspection
C. In-line inspection tools (smart pigs)
D. Cathodic protection
Smart pigs travel inside the pipeline and use sensors to detect
internal corrosion, cracks, and other anomalies.
5. Which of the following is a primary form of external corrosion
control?
A. Coating
B. Cathodic protection
C. Hydrostatic testing
D. Pigging
Cathodic protection uses electrical current to prevent corrosion
of the pipeline from external sources.
6. What does MAOP stand for?
A. Maximum Allowable Oil Pressure
B. Minimum Active Operating Pressure
C. Maximum Allowable Operating Pressure
D. Minimum Authorized Operating Procedure
, MAOP is the highest pressure at which a pipeline may be
operated safely under regulatory guidelines.
7. Which pipeline failure mechanism is caused by internal high-
pressure gas erosion?
A. External corrosion
B. Stress corrosion cracking
C. Erosion-corrosion
D. Mechanical damage
Erosion-corrosion occurs when high-velocity fluids remove
protective coatings or metal, accelerating corrosion.
8. What is the main purpose of a pipeline risk assessment?
A. Reduce operating costs
B. Increase capacity
C. Identify and prioritize potential threats to pipeline integrity
D. Improve marketing
Risk assessments help operators allocate resources to the most
critical areas of the pipeline system.
9. Which of the following is considered a direct assessment method
for pipeline integrity?
A. Ultrasonic testing
B. X-ray inspection
C. In-line inspection with smart pigs
D. Cathodic protection
Direct assessment involves examining pipeline conditions directly
through inspections or monitoring tools.
10. What does the term “denting” refer to in pipeline integrity?
A. Corrosion under insulation
B. Mechanical deformation due to external forces
C. Coating failure
