4. Operational and Maintenance Activities
4.1. Risk Management Review
A five yearly Safety Management Study review for the MPBLL was carried out in 2012 as per the
requirements of AS2885 (refer to EESA document number S‐34‐102‐RAE‐G‐008). This workshop
review did not identify any significant threats that had not been identified in previous workshops,
nor did it identify any significant shortcomings in the controls required to be applied in accordance
with AS 2885.
4.2. Training
EESA continues to meet its contractual, operational and technical requirements in a safe and
competent manner by ensuring its employees and contractors have the relevant competencies
to meet the challenges of the gas transmission industry.
On an ongoing basis our training and development team, along with key personnel ensure that
current employee skills and competencies are of the highest level, in alignment with legislative
requirements and industry standards.
Training is maintained by utilising a Learning Management System program. The system identifies
individuals required to complete mandatory training, ensuring the employee has the right skills &
knowledge to confidently continue to carry out their duties; also eliminating any potential non‐
conformance.
When individuals or groups are identified as requiring training, there are a number of methods
and platforms used, including: In‐house ‐ self‐paced modules, group presentations and one on
one session’s; External ‐ Registered Training Organisations; Professionals offering certified and
specialised courses; Lectures seminars and conferences.
Courses and training undertaken by both Epic personnel and contract labour is listed in Table 2
below:

4.4. Pipeline Patrol Activities
Three monthly road and aerial patrols (aerial patrols are conducted between PS3 and the Port
Bonython terminal only) scheduled to alternate at six weekly intervals were completed in 2014.
The road and aerial patrols ensure that the following pipeline activities are addressed:
signage is in suitable condition and if not, repairs are affected as soon as is practically possible. Any issues not addressed during the patrol are fed back into the CMMS in the form of a work order and scheduled for repair as resources permit;
to ensure there are no unauthorized activities occurring along the pipeline route or at any of the facilities;
restoration of any soil erosion due to wind and water is addressed;
there are no leaks occurring at any of the pipeline facilities or along the pipeline route;
all sites are secure, kept clean, neat and tidy; and
items including above ground pipe coating condition, fences, gates, padlocks, signage, fire extinguishers, weeding and other housekeeping activities are addressed at the mainline valve and scraper station facilities associated with the pipeline system.
Signage that required replacement was replaced between Moomba and PS3 (MAPS Compressor
Station 4) in 2014.
Low depth of cover issues identified on routine patrols at KP380, KP485 and KP600 were rectified
in November 2014. No significant issues were identified during Pipeline Surveillance activities
during 2014.
4.5. Leak Detection
EESA’s Pipeline Control Room (PCR) located at Dry Creek, South Australia operates a SCADA system that continuously monitors the MPBLL. Incorporated into the SCADA package is a Pipeline Leak Detection System (LDS) that provides real‐time leak detection capability based on line pack inventory, flows in and out of the system, hydrocarbon type and pressure and temperature change rates. This provides alarms to allow the duty controller to respond to and action any anomalies that may be occurring and notify field maintenance personnel to investigate further onsite if and as required.
Page 10 of 35
The PCR staff can, if required, isolate the pipeline remotely using any one of 17 out of 24 remotely operable valves to isolate sections of the pipeline and minimise any leakage.
The real‐time leak detection system is supported by maintenance activities along the pipeline (e.g. patrols, valve servicing) that assist in the identification of any pipeline leakage and ensure that appropriate resources are mobilised to address the problem in a timely manner.
Santos has an active project to upgrade the leak detection system on the pipeline. The project
milestones include:
comprehensive review of prepared documents and supplier proposals;
workshop, attended by key stakeholders, identified key areas requiring further investigation;
field trip along the pipeline to check and review LDS and radio network hardware;
completion of the draft Front End Engineering Design (FEED); and
confirmation that the first three sites along the communications network will be subject to
embargo in 2‐3 years.
To progress to the next phase, the key areas requiring further input are baseline performance of the existing LDS, verification of the future communications system to support the LDS and determination of LDS specification. No leaks occurred in the MPBLL in 2014. All leak alarms were investigated by the PCR duty
officer and found to be spurious. An ongoing alarm rationalisation process is being run by EESA
in parallel with Santos leak detection software replacement project to ensure continued
vigilance in monitoring MPBLL operations and following through all alarms and notifications.
This project is anticipated to continue in 2015.
4.6. Coating Integrity
EESA carries out coating defect (direct current voltage gradient, or DCVG) surveys on the MPBLL
every three years in accordance with the Santos‐prepared Integrity Management Plans (IMP):
AIMS‐PI‐IMP‐6469 for the pipeline section between Moomba and PS2;
AIMS‐PI‐IMP‐7081 (PS2 to PS3);
AIMS‐PI‐IMP‐7082 (PS3 to PS4); and
AIMS‐PI‐IMP‐7083 (PS4 to Pt Bonython)
The most recent DCVG survey was completed in 2014. A defect comparison report was prepared
to assess 2014 survey results with those recorded in 2011. This comparison identified eight
defects warranting verification by direct assessment. These are to be planned as required by
Santos in accordance with the overall IMP.
All defects identified in the 2011 coating survey have been excavated, inspected and repaired as
recommended in the survey report.
The pipeline coating system is considered to be in good condition. The defects repaired to date
have been in areas affected by boulders in trenches, or due to manual handling during
construction and the absence of padding causing mechanical damage to the coating. Some minor
Page 11 of 35
coating issues have been found in the past where pipe work enters the ground, especially at MLV
sites. These have been repaired where appropriate and all ground interfaces are monitored as
part of regular maintenance activities.
No major corrosion, pitting or stress corrosion cracking has been found on the pipeline to date.
All corrosion anomalies are acceptable to the requirements of AS 2885.3.
Above ground coating work carried out in 2014 including painting MLVs 2 through 10, as well as
the pig launcher and receiver at PS2.
4.7. Cathodic Protection
CP full line surveys were completed in 2014 as part of EESA’s preventative maintenance program
for the MPBLL. On/off readings are taken at all test points to assess the pipe to soil potential, and
ensure the potential on all parts of the pipeline is equal to, or more negative than ‐850 mV with
respect to a saturated copper/copper sulphate reference electrode (the ‐850 mV criterion). The
default program requires two surveys: one in winter and one in summer, to provide for seasonal
variation in ground conditions (moisture and temperature).
The most recent CP full line survey was carried out in August 2014. This survey reported a total
measured compliance of 97.54% based on a total of 488 test post readings. The previous full line
survey, carried out in February 2014 showed 93% compliance.
CP station checks are also carried out every two months to check the condition and performance
of the transformer rectifiers (TRs). The most recent survey was completed in December 2014,
reporting a total equipment reliability of 100%.
Refer to Appendix B for a graphic representation of full line compliance figures and TRU survey
results during 2014.
Other CP system refurbishment activities completed during 2014 include:
Installation of 26 new test posts between Moomba and PS3; and
Installation and commissioning of new modular TRs for locations KP161.4 and KP402.6, both damaged by lightning strike.
Under the CP system refurbishment program the installation of twenty new test posts and two
new modular TRs have been identified for the 2015 program.
A CP audit was carried out by Santos in 2013 to identify any gaps in the management of CP
systems against AS2832.1. Improvement opportunities were identified in the following key areas:
Data review and assessment to ensure proper operation of CP system;
Interference testing and control of interference current;
Commissioning of cathodic protection systems;
Maintenance of CP test equipment; and
Demonstration of competence of personnel
Page 12 of 35
As part of the CP Audit recommendations, a mutual interference testing program was
implemented in 2014. Interference testing was carried out in the Moomba South Central Area
and in the vicinity of the Port Bonython Liquids Plant. The interference testing shall be carried out
once a year and shall involve both EESA and Santos representatives.
A follow up to the CP Audit recommendations was carried out in 2014 by Santos, finding
improvements on the key areas pointed out by the Santos auditor. These areas will be monitored
during the CP quarterly meetings.
4.8. Electrical and Instrumentation Maintenance Activities
Routine quarterly pressure and temperature transmitter calibrations were completed in 2014 to
verify the accuracy of data being fed into the SCADA system, allowing accurate control of the
liquids hydrocarbon transportation process to ensure it stays within the design parameters at all
times.
Six monthly mainline valve remote operational checks were carried out in conjunction with
scheduled routine pressure and temperature transmitter calibrations. All sites were tested twice
in the year as per the 6 monthly scheduling requirements.
The flow computers at Moomba and Port Bonython were replaced as they had reached the end
of their lifecycle. The original three Sarasota flow computers controlling three meter runs were
replaced with two Emerson FloBoss S600+ units. One new flow computer controls all three meter
runs simultaneously and at both locations set‐up in a duty and stand‐by configuration. The
installation was completed within the planned schedule with minimal production interruption.
4.9. Communications
All process variables and valve control functions are communicated to the central control system located at PCR at Dry Creek Adelaide via a microwave link that runs parallel to the buried pipeline system.
In addition to the microwave link, a VHF radio link to allow voice communications between staff and the PCR plus a UHF link to transmit process data and commands to the main microwave link from remote sites are also supported by the communications system.
This system is essential for the safe monitoring and control of the pipeline and the following range of routine maintenance activities were carried out in 2014 to ensure the communications system provided a constant level of availability and reliability:
Routine Microwave bearer, UHF and VHF communications system maintenance tasks;
Routine maintenance tasks associated with the SCADA RTU calibration;
Routine maintenance tasks associated with the communications system uninterruptible power supply batteries and their associated charging system;
Routine maintenance tasks associated with the communications system solar generated power supply batteries; and
Six monthly communications equipment air conditioning unit maintenance.
Page 13 of 35
All communication outages were minor in nature and for short periods. There were no significant
communications issued reported in 2014.
EESA will be reviewing options to improve reliability of the communication system in 2015 to
address these minor outages.
4.10. Mechanical Maintenance Activities
Routine six monthly mainline valve and scraper station maintenance tasks were carried out in
2014.
All pipeline pressure regulator and over pressure protection devices were tested in compliance
with the relevant Australian standard and the maintenance schedule.
Ancillary equipment, such as pipe supports, pipe ground entry points, valves and pigging facilities,
are routinely inspected as part of the facilities inspections and as a part of the mechanical
maintenance routines. The stem seals were replaced in MLVs 24 & 25 in 2013. This involved the
removal of the MLV actuator and installation of new seal carriers and seals to ensure the integrity
of the stem seals in the MLV’s.
An ongoing program of stem seal replacement is planned for 2015.
4.11. Pipeline Integrity
Pipeline external corrosion is monitored and controlled by carrying out six monthly full line on/off potential surveys, 2 monthly Cathodic Protection Unit (CPU) surveys and painting programs for above ground facilities. Refer sections 4.6 and 4.7 above for further detail.
Four locations between Moomba and PS4 were excavated in 2014 for direct assessment based on the results of the 2009 In Line Inspection (ILI). All locations were recoated with no significant defects identified. Minor stem seal leaks on the Adamson Chronister MLVs have developed at several sites along the pipeline. Santos engaged an external consultant to design and develop a prototype assembly to carry out permanent repairs to these sites. Testing and preliminary site work has been completed in 2012, and full repairs were carried out at MLV 24 and MLV 25 in 2013.
Whilst MLV25 had a like for like seal installed, MLV24 had a prototype installed under pressurised conditions. The lessons learnt from this will be reviewed and changes made to the repair procedure for the remaining 23 valves.
4.12. Pigging
In accordance with the Santos Moomba – Port Bonython liquids line Pipeline Integrity
Management Plan a combined corrosion inhibitor (CORTON IRN 2449) treatment and pigging
program was carried out in March 2014. Pig Trash samples were collected for analysis to monitor
Bacteria (SRB) levels during each pigging run. These samples were sent to Port Bonython
laboratory for analysis.
Page 14 of 35
5. Incident Reporting
There were no serious or reportable incidents associated with the MPBLL during 2014.
6. Land Management
6.1. Land Owner Liaison
There are approximately 44 landholders along the MPBLL. In January 2014 EESA began an 18
month Land Owner Liaison Program to visit all properties (or other nominated contact
addresses), completing a questionnaire during the visit, updating contact details, current and
proposed land use, awareness of the pipeline location and reminding landowners of their
responsibilities with respect to working in the pipeline vicinity. Where landholders were not
available to be seen in person, the questionnaire is completed via telephone. EESA is currently
on target for completion in June 2015, and will then revert to a 12 month program aligned with
the Financial Year rather than Calendar Year.
Landowners who have been involved with encroachments or near‐misses in the past will be
visited twice during the extended program.
As part of EESA’s pipeline awareness program, all landowners were also contacted via mail on
two occasions, with a newsletter sent in May 2014 emphasising the importance of using the Dial
Before You Dig (DBYD) system and a 2015 EESA calendar containing information on pipeline
safety and their responsibilities sent in December 2014.
6.2. Pipeline Safety Awareness
EESA conducts a Community Awareness Program, which entails holding awareness meetings with
communities, government departments, utilities, emergency services and contractors along the
pipeline route. Twenty six of these meetings were held in the mid north with services in close
proximity or associated directly with the MPBLL. Some of these presentations were held in
conjunction with presentations for the Moomba to Adelaide Pipeline System (MAPS).
The presentations focused on MPBLL as well as the MAPS, and included information on the general
properties of the liquid hydrocarbons transported, the process of liquids hydrocarbon
transmission by pipeline, location of the high pressure liquids pipeline in the regions concerned,
correct procedures when working within pipeline easements, pipeline threats and dealing with
emergency situations. (Note: The presentations are tailored to the specific audience and where
appropriate EESA discusses the differences between Liquids Hydrocarbon and natural gas
transportation as both pipeline systems exist in a number of areas within South Australia).
6.3. Pipeline Locations and Referral Services
EESA continues to provide a free service to locate any pipeline that they own or operate on behalf
of third parties. Historically this service was primarily used by companies and third parties carrying
Page 15 of 35
out civil works in the vicinity of the pipelines, with contact made via either direct telephone to
EESA or via the free call 1100 “DBYD” asset referral service.
In 2014 EESA continued emphasising to all landowners the importance of using the free DBYD
service for any works near a pipeline.
EESA received twenty one DBYD enquiries in relation to third party activity in the vicinity of the
MPBLL.
In 2014 EESA updated the ‘Managing Third Party Works Procedure’ to provide a clear and well
defined process for managing significant land disturbing activities near the pipeline.
7. Environmental Management
7.1. Control Document and Training
EESA regularly reviews and updates elements of the Environmental Management System (EMS)
including the relevant environmental procedures and work instructions and specific
Environmental Management Plans (EMP).
In 2014 EESA updated online environmental training module and provided training to all
employees and contractors entering the field on behalf of EESA. This induction provides an
overview of environmental risks, control measures and responsibilities.
The documents reviewed and updated in 2014 were:
African Rue Management Plan;
Bushfire Management Procedure;
National Pollutant Inventory Reporting Procedure;
Weed Management Procedure
7.2. Weed Control – African Rue
The recently updated African Rue Management Plan describes a three year program to trial new
herbicides and rate performance using different spray techniques.
The plan includes:
Restriction of vehicle and machinery access into infested areas;
Vehicle hygiene procedures implemented where access to infested areas is unavoidable;
Signage to allow for easy identification of infested areas;
A herbicide spray program along the easement conducted annually;
Herbicide spray trials to identify the most effective products and application methods; and
Monitoring weed distribution. The management plan has proven effective in controlling populations and preventing the spread
of African Rue along the pipeline easement.
Page 16 of 35
7.3. Soil Erosion and Subsidence Management
No erosion or subsidence was reported in 2014.
7.4. Environmental Audits and Monitoring
Following completion of the 2014 MPBLL Repair Program, an audit was conducted on
compliance with environmental requirements of EESA’s Excavation Procedure. Excavation
checklists and photograph records completed during the repair program, demonstrate
compliance with the procedure.
Of the four pipeline repair locations, two were selected as a representative sample to be
included in EESA’s Environmental Monitoring Program, whereby they will be monitored annually
for vegetation cover and erosion for at least five years, or until such time as they are deemed to
resemble the surrounding landscape.
7.5. Cultural Heritage
No cultural surveys were required on the MBPLL in 2014. No cultural sites were identified by
EESA workers.
7.6. Assessment of Declared Environmental Objectives
Appendix A contains the “Assessment of Declared Environmental Objectives” completed for the
MPBLL.
8. Emergency Response
The Petroleum and Geothermal Energy Regulations 2013 require that an Emergency Response
exercise is to be conducted on the MPBLL once every two years, and in addition to this exercise a
set of Emergency Response procedures is to be developed and maintained. These procedures are
detailed in EESA’s “Incident Management Plan”.
EESA have reviewed the outcomes of the 2012 exercise and have developed an Emergency
Response Plan in line with the new EESA organisational structure.
Exercise “Liquid Line Pipe Strike” was carried out on the 6 August 2014 involving Santos personnel
located at Dry Creek, EESA field personnel, EESA Dry Creek personnel and the PCR. The exercise
was considered a success with a number of learnings incorporated into the Incident Management
Plan and the training regime.
Issues and observations made during the exercise have been addressed. Amendments to the
Emergency Response Manual are required. Santos is in the process of providing feedback to allow
EESA to issue the revised manual.
Page 17 of 35
9. Regulatory Compliance
EESA ensures that design, manufacture, construction, operation and maintenance and testing of
all appropriate facilities is carried out in accordance with the relevant Acts of Parliament, licence
conditions and AS2885 requirements.
EESA attends quarterly meetings with DSD and Santos, where operational regulatory compliance
is discussed in an open manner.
EESA monitors legislative changes through SAI Global, an organisation which monitors, tracks
and advises EESA of legislative changes that could affect the operation of the pipeline.
EESA is not aware of any regulatory non‐compliance for this pipeline, and believe it is fulfilling its
obligations in relation to the following requirements:
Petroleum and Geothermal Energy Act 2000;
Petroleum and Geothermal Energy Regulations 2013;
Pipeline Licence 2 (PL2); and
The Statement of Environmental Objectives (SEO) for PL2
Significant items are reported through to DSD and are raised at quarterly compliance meetings
held between DSD, Santos and EESA.
There have not been any significant regulatory compliance issues during this reporting period.
10. Risk Management
EESA has continued to use the Safety Management System (SMS) that was established during
2013 that meets obligations under the harmonised Workplace Health and Safety (WHS)
legislation and AS2885:2012; and is aligned to AS4801 – Occupational Health and Safety
Management Systems.
The WHS Safety Management System consists of an overarching Safety Management Plan,
Policies, Guidelines, Procedures and Work Instructions; and has been implemented across all
elements of the business.
EESA utilise an online Risk Management database known as Corporate Governance Risk (CGR).
CGR is a web‐based risk management platform that performs the following key functions:
Risks, which incorporates HAZID style workshop outcomes, e.g. risks, causes, controls,
consequences and risk rankings;
Learnings, which captures HSE and operational lessons learnt, including related actions;
Actions, which tracks actions from risk workshops, incident reporting, inspections/audits and
meetings;
Incidents, which records information on incidents in the areas of clinical health, injury,
environment, asset, reputation, security, legal and financial; and
Page 18 of 35
Audits, which allow audits and other checklists to be created and generated.
Recommendations arising from the checklists can be elevated to actions and transferred to the
action component.
11. Management System Audits
11.1. Health and Safety
WHS audits are undertaken by EESA to provide assurance and to assess the effectiveness of WHS
management practices to determine if they are effective for ongoing and future management of
significant risks in line with best industry practice and company policies.
A legal compliance audit was conducted by the firm Norton Rose Fullbright in April/May 2014. A
comprehensive 3 Year WHS Plan was established identifying 7 key areas for the company to work
on.
Audits undertaken during 2014 are listed below:
Norton Rose Fullbright legal compliance review;
WHS and Assurance;
DSD Self‐Assessment audit alignment to AS4801; and
63 field based safe systems of work observations / audits
In addition to these systems audits, EESA have established, as part of its Tasks and Targets for
Supervisors and Managers, tools to conduct field based quality assurance inspections to ensure
that the system is being appropriately utilised in the field.
11.2. Management Audit
EESA completed a number of management audits during 2014. These were a combination of
EESAs internal audit program and external audits by industry experts initiated by EESA.
The following topics were subject to audit during 2014:
