Inspection & Testing
engineers and technicians are qualified to conduct site investigations and inspections
and prepare professional reports on the conditions on any installation, with
recommendations for upgrades and additions to ensure the site complies with all
Petrolink Engineering has
qualified and accredited API 653 Aboveground Tank Inspectors and can carry out
mandatory periodic tank inspections as required in accordance with relevant
Standards. Inspection of above-ground storage tanks include thickness testing
to ensure all surfaces still have the required minimum wall thickness (see Tank
Integrity testing below).
Underground tanks are
regularly cleaned and inspected internally to identify any faults and remove
residual sludge and other un-desirable matter to ensure continuing cleanliness
of the product stored.
Steel tanks are
inspected for signs of corrosion and other issues which could compromise the
life expectancy of the tank.
Fibreglass tanks are
inspected for signs of de-lamination which could compromise the life expectancy
of the tank.
Inspection of under-ground
tanks include vacuum testing of tank and pipelines to ensure the integrity of
the tank has not been compromised (see Tank Integrity testing below).
A report is prepared following any tank inspection which include all results from the investigation and any recommendation for repair and improvements to prevent any further degradation of the tank and the risk of contamination to the environment.
Tank Integrity Testing
Also, if necessary Petrolink
can conduct Tank Integrity Testing which involves a team of trained industry
professionals addressing matters such as;
Thickness testing of tank
shells, floors and roofs to ensure the material thickness is still above the
minimum required as per Standards, and then calculate remaining life expectancy
to ensure the tank is safe to use at least until next mandatory tank
inspection. Thickness testing of tanks is usually conducted as part of
Above-ground Tank Inspections (see above).
The integrity of underground
tanks is tested using our specialised vacuum testing system and methodology. A
specialised computer software programme analyses the results which are
incorporated into a report for the tank.
Pipeline Integrity Testing
Hydrostatic testing of
pipelines includes pressure testing of the pipelines using either water or the
product in the pipelines if mixing the product with water is unacceptable.
Pneumatic testing of new
pipelines if hydrostatic testing with water could pose problems if all water
cannot successfully be removed following the testing.
Mixed hydrostatic and
pneumatic testing with nitrogen if the product in the pipelines cannot be
removed for the testing.
All pipeline integrity
testing is conducted in accordance with relevant Australian Standards.
Fuel bowser calibrations
Petrolink Engineering technicians are trained and certified to carry out mandatory fuel bowser calibrations to meet standards in accordance with the National Measurement Institute (NMI)
All works in compliance with
and to relevant Australian Standards and Regulations
(AS 1940, AS 4897, AS 4037,
NMI, API 2000, API 653 and more.)
