4 OPERATIONAL & MAINTENANCE ACTIVITIES - 2012

4.1 Risk Assessment Review

A five yearly SMS review for the MPBLL was carried out in 2012 as per the requirements of AS2885 (refer to Epic 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. Notwithstanding, the workshop identified and prioritised a number of actions that need to be completed to demonstrate ALARP. These actions generally relate to strengthening existing procedures to further mitigate horizontal directional drilling and rabbit ripping threats. High priority actions were raised for:

Assessing the threat of installation of communications cables by plough, and better understanding the

likely depth of installation and whether the pipeline can resist penetration from a cable plough

Developing a Fracture Control Plan (including critical defect length calculations)

Confirming the “measurement length”, due to conflicting information cited during the workshop

Better understanding the environmental consequences of various pipeline failure scenarios.

Epic Energy maintains this risk assessment action item register, and is working through the total of approximately 60 action items raised in the workshop.

4.2 Training

Epic Energy is committed to developing the skills of their employees and contractors to meet the operational needs of its business. During 2012 staff training was conducted in-house using a number of techniques which included training courses developed specifically for Epic Energy and delivered using self paced modules or as a group presentation using either a training service provider or suitably skilled Epic Energy staff. In addition to internal training, staff attended a range of external courses selected to further enhance their knowledge of the natural gas and liquid hydrocarbon pipeline transmission industry.

TRU switching unit replacements. A summary of the Operations and Maintenance activities for 2012 and proposed activities for 2013 is provided below.

4.3.1 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 2012. 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


of 35

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.

A risk assessment completed by Santos for a previously detected internal gouge anomaly, at approximately KP 78 on the Moomba – Port Bonython Liquids Pipeline, required Epic Energy to conduct additional weekly road patrols between Moomba and PS No# 2. The purpose of these patrols was to inspect the integrity of the Moomba to Port Bonython liquids pipeline and the safe condition of the defect excavation site left exposed for future pipeline integrity monitoring activities. Based on the Fitness For Purpose and Fatigue desktop analysis carried out, these patrols were reduced from weekly to monthly intervals from September 2009 and have since been extended to a bi-monthly patrol in 2011 with additional NDT testing of the pipe work every 6 months. In the later portion of 2012 a project commenced to cut out and replace the affected pipework. Additional information on this anomaly repair is included in section 4.3.8. In 2012 routine patrols of the pipeline easement and ROW have identified areas of the MBPLL affected by water erosion after periods of heavy rains and localised flooding, however the pipeline has not been exposed at anytime during this reporting period. Damaged areas were repaired immediately to provide a protective depth of cover, these repairs were followed up with an extensive repair program to reinstate affected areas to their original state and provide more permanent repairs to eliminate future issues. No significant issues were identified during Pipeline Surveillance activities during 2012.

4.3.2 Leak Detection

The Epic Energy Transportation Services Control Centre (TSCC) located in Melbourne operates a SCADA system that continuously monitors the Liquids pipeline. Incorporated into the SCADA is the Pipeline Leak Detection System 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. The control centre staff can, if required, isolate the pipeline remotely using any one of 17 out of 24 valves, isolating sections of the pipeline to minimize any leakage should the need arise. The real-time leak detection system is augmented by maintenance activities along the pipeline which assists in the identification of any pipeline leakage ensuring the appropriate resources are mobilized to address the problem in a timely manner. The Liquids Real-Time Leak Detection Model operated 98% of the time, with short term outages related directly to RTU communication problems at either Moomba or Port Bonython. A simulated test of the real-time leak detection system is carried out annually in November in accordance with the annual maintenance plan. The one for 2012 was completed as required and validated as passed to meet the requirement of leak detection rate of less than 11m

3/hr.

4.3.3 Coating Integrity

All defects identified in the 2008 Gippsland Cathodic Protection Survey Report with a %IR >15 have been excavated, inspected and repaired as recommended in the report. A DCVG survey was completed in 2011 in accordance with the Santos Integrity Management Plan. A defect comparison report has been prepared, comparing data from 2008 and 2011 data, and the latest DCVG survey report has identified 7 defects with %IR > 15. High-priority defects, based on Santos advice, are to be verified in 2013.


of 35

The pipeline coating system has performed well; the defects repaired to date have been in areas affected by boulders in trenches, handling of pipes during construction stage and absence of padding causing mechanical damage on the coating. Some minor coating issues have been found in the past where pipe work enters the ground, especially at MLV sites. No major corrosion, pitting or stress corrosion cracking has been found on the pipeline to date. All corrosion anomalies were acceptable to the requirements of AS 2885.3.

4.3.4 Cathodic Protection

The last CP full line survey was carried out in October 2012 in accordance with the maintenance plan, reporting a total measured compliance of 85% based on total 488 test posts (note at the time of writing the report, survey had progressed 75%). The previous full line survey, carried out in February 2012 showed 83% compliance. Last TRU 2-montly survey was carried out in Nov/Dec 2012, reporting a total TRU Reliability of 83%. Average CP compliance during 2012 was 84% based on total 488 test posts, in accordance with AS2832. Average TRU Reliability for the period was 84% based on 12 units installed. It is important to note that there are some areas of the ROW where access is difficult, particularly between PS3 and PS4. Epic and Santos are working together to find a solution for effective reinstatement of access to these areas. As at November 2012, readings cannot be obtained from 36 CP test posts due to damage. These have been reported by Epic Energy to Santos and a process is in place for their reinstatement in 2013. For a graphic representation of full line and TRU survey results during the period 2012, as well as compliance figures, refer to Appendix B Cathodic Protection system refurbishment activities completed during 2012 include:

a) Installation and commissioning of a new ground bed replacement inside the Moomba compound. b) Installation of a new Transformer Rectifier inside the Moomba compound (commissioning planned

for 1Q13) c) Purchase of two replacement Transformer rectifiers for locations KP161.4 and KP402.6, both

damaged due to lightning strike. Installation planned for 1H13. As planned, a CP Audit was carried out by Santos to identify any gaps in the management of cathodic protection systems against AS2832.1. An action plan has been developed for Santos and Epic to address throughout 2013, including joint interference testing (4Q 2013). 4.3.5 Electrical and Instrumentation Routine quarterly pressure and temperature transmitter calibrations were completed in 2012 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. Due to inconsistent data a minor project was undertaken to visit all pressure and temperature transmitters and calibrate out of cycle with the approved maintenance plan. This was done to ensure that sensing lines were not obstructed and creating inaccuracies in the readings. Minor deposits were found in the transmitter lines and as such were removed and cleaned.

4.3.6 Communications All process variables and valve control functions are communicated to the central control system located at the TSCC in Melbourne 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 control centre 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 2012 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.

Six monthly communications equipment air conditioning unit maintenance. The 3 yearly mast maintenance program was completed in accordance with the Moomba – Port Bonython Liquids Pipeline maintenance plan. The scope of work included inspection of the fifteen (15) structures, ancillary equipment, earthing systems, foundations, anchor blocks, mast alignment and mast guy wire tensioning. Ancillary equipment is inclusive of cable trays, ladders, aviation lights, antennae and feeders. Reports have been provided in hard copy for the 15 sites and will be filed at Dry Creek in the Central Filing System. Reports advised minor tensioning of guy wires was carried out and a recommendation to upgrade the ladders at all sites, one of the twin aviation LED lights at mid location on the towers were reported blown at CS2 and CS3. A follow up mobilisation of the contractor was required to replace the lights. All communication outages were minor in nature and for short periods, there were no significant communications issued reported in 2012.

4.3.7 Mechanical

Routine six monthly mainline valve and scraper station maintenance tasks were carried out in 2012. 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. PS2 was painted in the month of December in accordance with the maintenance programme. Pressure vessel Internal/ External inspections were carried out in February 2012. Results of these inspections that do not require engineering input have been entered into the maintenance system and are scheduled to be completed in Q1 2013. Any actions requiring Engineering assessment have been forwarded to Santos for Engineering review and feedback.

4.3.8 Pipeline Integrity A section of pipeline approx 78 kilometres south of Moomba has been identified with internal metal loss defect discovered during the Rosen AFD inline inspection run between Moomba and PS2 in 2009. Metal shavings detected in the pig receiver vessel after a pigging operation to remove a flow enhancer nozzle and a hot tap drill was the driver for running the inline inspection tool. The final report from the AFD inline inspection tool reported minor spirally orientated gouging anomalies with between 5%-9% wall loss. Replacement of this 2Km section commenced in 4Q12 and is expected to be finalised by 1Q13. During 2012 additional bimonthly road patrols between Moomba and PS2 have been carried out to monitor the buried pipeline with special emphasis on the defected section and the excavated section at KP78.

NDT inspection performed (phased array scan ultrasonic) on the excavated section in March and September 2012 have shown no deterioration of the defect. Approximately two (2) kilometres of pipeline has been identified for replacement in Q4 2012 to Q1 2013. Bacteria activity on the Moomba to Port Bonython Liquids Pipeline continued to be monitored and controlled by several activities in accordance with Moomba - Port Bonython Liquids Line Integrity Management Plan in 2012. In 2012 the bacteria levels continue to be low in comparison with levels seen in 2010, which improved throughout 2011. Oil samples are taken at each pig vessel during the 2012 pigging program and forwarded to Santos laboratories for bacteria (SRB) analysis. Pipeline external corrosion is monitored and controlled by carrying out 6 monthly full line on/off potential surveys, 2 monthly CPU surveys and painting programs for above ground facilities. No ILI or DCVG defects were excavated or repaired during 2012, data from the last ILI and DCVG survey have been reviewed and a number of locations are planned for excavation and verification during 2013 in accordance with Santos’ recommendations. Minor stem seal leaks on Adamson Chronister Main Line Valves have developed at several along the pipeline. Santos has 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, with final work schedule yet to be developed by Santos. As part of this exercise, MLV sealing capacity was tested on all MLVs during 2012 using two different types of sealant, several valves could not achieve 100% sealing capacity when blowing down the valve cavities with the valves in a closed position and pressure on both sides of the valves. A true sealing capacity test can only be performed with pressure on one side of the slab, this cannot be achieved with the current pipeline operating conditions.

4.3.9 Pigging operations

In accordance with the Santos Moomba – Port Bonython liquids line “Pipeline Integrity Management Plan” the following pigging operations were carried out in 2012:

A combined corrosion inhibitor (CORTON IRN 2449) treatment and pigging program was carried out in

February 2012. 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.

5 INCIDENT REPORTING

There were no reportable incidents associated with the Moomba – Port Bonython Liquids Pipeline during 2012.

6 LAND MANAGEMENT

6.1 Land Owner Liaisons

There are 44 landholders along the Moomba to Port Bonython Liquids Pipeline system. Every landowner on the pipeline was visited during 2012 and a questionnaire was completed as part of each visit. The questionnaire is centred on confirming contact details, current and proposed land use, awareness of the pipeline location and reminding landowners of their responsibilities with respect to works in the pipeline vicinity. As part of Epic Energy’s continuous improvement program for pipeline awareness, the landowners were posted one letter and a postcard during the year containing information on pipeline safety and their responsibilities. An Epic Energy year 2013 calendar reminding the landowner of pipeline safety was also forwarded in December 2012.

6.2 Pipeline Safety Awareness

Epic Energy implements a Community Awareness Program, which entails holding awareness meetings with communities, government departments, utilities, emergency services and contractors along the pipeline route. Two (2) of these meetings were held in the mid north with services in close proximity or associated directly with the Moomba – Port Bonython Liquids Line. The presentations focus 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 Epic Energy 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 Location and Referral Services

Epic Energy provides a free service to locate any pipeline that they own or operate on behalf of third parties. This service is primarily used by other companies and third parties carrying out civil works in the vicinity of the pipelines. During 2012 Epic Energy received four enquiries via the free call 1100 “Dial Before You Dig” asset referral service in relation to third party activity in the vicinity of the Moomba to Port Bonython Liquids Line. Two of these required on-site attendance by Field Maintenance Officers and a third required dialogue with the requestor regarding plans for a potential new facility at Port Bonython. 7 ENVIRONMENTAL MANAGEMENT Control documentation and training Environmental procedures and work instructions continue to be reviewed and updated as necessary. In early 2012, the online environmental training module was completed and implemented. This induction provides an overview of environmental risks, control measures and responsibilities. All Epic Energy employees and contractors entering the field are required to complete the training. African Rue Epic Energy closely monitors African Rue and has an effective control strategy in place including:

Restriction of vehicle and machinery access into infested areas;

Vehicle hygene 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 conduced annually; and


of 35

Monitoring at infested sites. An African Rue Management Plan detailing the above has been implemented following review by the South Australia Arid Lands Natural Resource Management Board. Environmental Protection Soil erosion and subsidence management: An unstable embankment at KP509 was restored through installation of a reno mattress and gabion. Appendix A contains the “Assessment of Declared Environmental Objectives” completed for the Liquids Line.

8 EMERGENCY RESPONSE

PL2 states that an Emergency Exercise is to be conducted on the Moomba – Port Bonython Liquids Pipeline 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 Epic Energy’s “Emergency Response Manual”.

Epic Energy and Santos carried out a joint desk top emergency response exercise on the 4rd

July 2012 and forwarded a report to DMITRE on the 2

nd August 2012. The exercise was carried out in accordance with “The

Regulations Under the Petroleum & Geothermal Energy Act 2000 “ and the requirements of PL2 emergency drill is required every two years to test emergency procedures and a report is to be submitted to the regulator (DMITRE) within 60 days of the drill. The objectives of this desk top exercise were to have the key emergency response personnel from both Epic Energy and Santos involved to ensure both parties had a clear understanding of their roles and responsibilities in the event of an emergency on the Moomba – Port Bonython Liquids Pipeline. Four specific objectives were identified to be addressed during this exercise:

1. To use the new DRAFT version of the Moomba – Port Bonython Emergency Management Plan throughout the desk top exercise and to confirm both parties were comfortable the EMP had clear and accurate information.

2. To ensure the communication between Epic Energy and Santos was understood and the

responsibilities of both parties for notifications to government regulatory bodies and emergency services were clearly described in the ERP.

3. Review the roles and responsibilities to ensure communication and decision making by both Epic Energy and Santos were clearly described within the ERP.

4. Review emergency response situations and confirm that the responsibility of control for stages throughout the emergency was clear for both parties and appropriate emergency response equipment is available.

The exercise considered three types of leaks, a small leak (pin hole corrosion), a medium leak (backhoe penetration of the pipeline) and a major leak (full line rupture)

For the sake of the exercise, the location was arbitrarily selected as being approximately 100 km south of Moomba. However, it was noted that specific emergency response actions at varying locations along the pipeline would depend on the elevation of the pipeline. During the exercise, the sequence of events and emergency response actions were considered in chronological order for a hypothetical leak, with the differences in consequences for each of the three leak types discussed separately. That is, three separate scenarios were not run. Rather, the general process of the EMP was stepped through, considering a full range of leak severities.


of 35

The emergency desk top exercise was deemed a successful activity with the objectives set prior to the exercise all being achieved and the working group leaving with a good understanding and several new learning’s related to a liquid hydrocarbon pipeline emergency. The new draft EMP was used for this exercise and with the recommended changes and additions from the working group will be a useful, user friendly document. Discussion held throughout the exercise confirmed that roles and responsibilities for both Epic Energy and Santos key personnel that will be involved in a real event were clearly identified. Santos and Epic Energy have had a long and good working relationship and demonstrated throughout this exercise they are capable of jointly responding and managing an emergency situation on the Moomba – Port Bonython liquids pipeline system Several recommended changes to the DRAFT Emergency Response Plan were identified and actioned as a result of this exercise.

9 REGULATORY COMPLIANCE

Epic Energy ensures that design, manufacture, construction, operation, maintenance and testing of all appropriate facilities is carried out in accordance with the relevant Acts of Parliament, licence conditions and the requirements of AS2885. Epic Energy attends quarterly compliance meetings with DMITRE, where operational regulatory compliance is discussed in an open manner. Changes in legislation are tracked and communicated through a legal compliance committee which meets on a monthly basis. Epic Energy maintains a compliance database, Safety Wise, which tracks legislative compliance throughout the organisation. Obligations are assigned to responsible staff, who must supply evidence that the obligation has been satisfied within a specified time period. Epic Energy is not aware of any regulatory non compliance for this pipeline, and believes it is fulfilling its obligations in relation to the following requirements:
