Corrosion Control Group
An Overview of the following specialist services provided by OICCG
Corrosion Control (CORO)
Installation, management and maintenance of Cathodic Protection
systems at at bulk liquid storage and handling facilities, along buried
and submerged pipelines and at underground storage tank retail installations.
Essentially this service comprises installation and maintenance of Cathodic
Protection (CP) systems.
was founded on this technology.
We are fully skilled in its application and are abreast of global
CP systems fail as a result of neglect to monitor their essential
operating parameters and perform regular maintenance.
provide a continuous management service for CP installations with
regular inspections and risk reports.
can integrate benefits from activities in CP, ASTI, RAP and PMP
in a cost effective and user efficient manner.
Risk Assessment Program (RAP)
RAP has been developed by the Oil Industry Corrosion Control
Group and is designed to assess the risk associated with Underground
Storage Tank (UST) systems typical of those found at petrol filling
stations. Life expectancy of UST systems has been found to vary widely.
Whilst mechanical failure due to poor construction is the main reason
for UST failure during initial service, thereafter corrosion becomes
the principle cause of leaks. The connecting steel pipes in a UST system
are particularly venerable to corrosion induced leaks. Capabilities:
- RAP provides a comprehensive assessment of UST systems. The
type of construction, soil characteristics, environmental sensitivity
and leak history are assessed to compute Risk Ratings and Failure
Prediction Index (FPI).
- RAP computes risk Ratings and FPI that are used in a risk
matrix to provide recommendations to reduce risk.
- RAP computes statistics associated with soil geology and corrosivity,
environmental characteristics and sensitivity as well as UST performance
used in determining trends and identifying high risk areas requiring
- Participants also have the option of using the RAP data in
conjunction with an OICCG managed Geographical Information System.
Above Ground Storage Tank Inspection System (ASTI)
ASTI has been developed by the Oil Industry Corrosion Control
Group and is designed to provide a systematic guide to tank inspection,
simplify inspection reports and facilitate management of tank data.
is based on OICCG tank inspection procedures that are guided by
provides standardised inspection specifications, stores historic
data, provides comprehensive evaluation reports and schedules future
are designed to extend tank life by 10 yrs. ASTI includes a tank
management system that archives tank data and schedules in-service
and out-of-service inspections.
Pipeline Management Program (PMP)
OICCG's Pipeline Management Program (PMP) covers a range
of technical, engineering and information services associated with the
installation, monitoring, maintenance and mapping of surface and sub-surface
marking and Differentially Corrected Positioning Survey (DGPS) of
of buried pipeline coating systems using Pipeline Current Mapper
(PCM), Direct Current Voltage Gradient (DCVG) and Close Interval
of data from different inspection sources including Pipeline Intelligent
of an integrated Geographical Information System (GIS) designed
as a decision support tool. The strength of GIS is the ability to
analyse the relationships between different sources of data within
the framework of GPS references. For example, high risk points on
a pipeline can be related to other data sets such as roads, property
boundaries, rivers, wetlands, boreholes, etc. example
a database platform and user interface for client data which is
maintained by OICCG. Predefined projects are available to participants
on CD-ROM to easily address common queries. OICCG handle more complex
queries from a centrally administered GIS.
Special Services offered by OICCG include non-destructive testing,
project management and corrosion consultantcy Capabilities:
- OICCG provide a comprehensive non-destructive inspection service.
- OICCG provide absailing rope access to high structures such
as aboveground storage tanks (ASTs). OICCG use this rope access to
carry out comprehensive UT on the shell of AST's.
- OICCG offer project management on turn-key projects which
can include, for example, design, installation and commissioning of
corrosion protection systems.
- OICCG provide a consultancy service to participants. OICCG
are members of the National Association of Corrosion Engineers, South
African Institute of Non Destrutive Testing and South African Corrosion
Institute and represents participants of various industry commities
including the South African Electrolysis Committee and South African
