2.4 Cathodic Protection Potential Survey

An annual cathodic protection potential survey of the Iona to Pelican Point pipelines and associated laterals occurred during August 2010. The survey was completed and results assessed in accordance with AS 2885.3:2001 Pipelines – Gas and Liquid Petroleum Part 3: Operation and Maintenance and AS2832.1:2004 Cathodic Protection of Metals Part 1: Pipes and cables.

The survey involved measuring the pipeline potentials with respect to a saturated copper/copper sulphate reference electrode at each test point and at nominally every fifth test point, recording the pipeline potential over a 20-hour period, as required for pipelines subject to the effects of telluric currents.

The results of the survey indicated that the SEA Gas pipeline and its associated laterals were fully protected in accordance with the protection criteria defined in Section 2.2 of AS 2832.1.

Page 7: South East Australia Gas Pty Ltd€¦ · pipeline potential over a 20-hour period, as required for pipelines subject to the effects of telluric currents. The results of the survey

Annual Report ( PL13 ) – Port Campbell to Adelaide Pipeline

2010 – 2011 Licence Year

Page 7

The survey also indicated that all AC (Alternating Current) surge protection devices installed along the pipeline were functional and found to be operating normally.

Readings were also taken on all corrosion probes, which were found to be operating normally.

The reconnection of the sacrificial anodes originally installed to provide temporary protection during construction appears to have been successful in reducing the magnitude of voltage variations due to telluric currents, however telluric current activity was reasonably quiet during the survey period.

During the course of the survey the Pelican Point corrosion probe was replaced and the Yallamurray cathodic protection rectification unit was repaired.

2.5 Pipeline Location and Referral Services

During the course of the licence year, 409 third party asset referral enquiries were received for the SEA Gas Pipeline System via the free call 1100, “Dial Before You Dig” asset referral service (0.7% increase from the previous year). In response to these enquiries, 241 were deemed to have a potential to affect the pipeline and were subject to site assessment (10.5% increase).

2.6 Emergency Response & Preparedness

During the licence year, SEA Gas participated in the following emergency response exercises:

Exercise Shortfall (4 August 2010, collaborative exercise with South Australia and Victoria police, security services providers and SEA Gas maintenance contractors);

Exercise Allegro (December 2010, SEA Gas internal exercise involving call simulations relating to emergency incidents);

Exercise BCR (12 – 13 January 2011, an exercise to assess capability to operate from the SEA Gas alternate control room);

Exercise Alianza (17 – 18 May 2011, annual Victorian gas industry exercise, jointly conducted by Australian Energy Market Operator, Energy Safe Victoria and the gas industry).

Emergency response exercises provide SEA Gas personnel and third party emergency stakeholders with realistic opportunities to activate and implement emergency response and crisis management plans, based on realistic incident scenarios along the pipeline in both South Australia and Victoria.

Recommendations arising from these exercises have been progressively actioned to enable continuous improvement and familiarisation with the SEA Gas Emergency Response and Crisis Management Plans. The progress of each action is tracked via the SEA Gas compliance action tracking system.

During the 2011 / 2012 licence year, SEA Gas intends to host:

a multi jurisdictional emergency response exercise (Exercise Broadview) involving emergency services in South Australia, which will be submitted as the bi-annual exercise in accordance with the requirements of sub-regulation 31(3) of the Petroleum and Geothermal Energy Regulations (SA) 2000; and

a joint emergency response exercise (Exercise Vulcan) in collaboration with Epic Energy, to assess combined emergency response processes.

595 Work Practices A SEA Gas staff member discovered the un-authorised installation of an ARMCO barrier on the pipeline easement during an environmental survey.

Installation of the barrier (ARMCO supports are 1 metre from the buried pipeline) occurred without prior knowledge of the licensee.

The Barossa Council engaged a contractor to install the ARMCO barrier on its behalf.

The contractor requested an 1100 Dial Before You Dig asset referral six months prior to installing the barrier, however failed to consult the licensee prior to commencing work (indicating that he conducted his own location based on information received from Dial Before You Dig).

Prior to commencing work on the pipeline easement a pre-start pipeline location was not requested by either the Barossa Council or their contractor.

Indicative placement of pipeline markers along the pipeline easement was relied upon to predict the location of the pipeline during the installation of the barrier.

Both the Barossa Council and the contractor were re-briefed regarding activities on the pipeline easement which require approval from SEA Gas prior to commencement and associated asset location by a SEA Gas representative.

The briefing included an overview of activities which have the potential to compromise safe operations on the pipeline easement.

A site inspection by SEA Gas representatives confirmed that the pipeline and its protective coating had not been damaged during the installation of the fencing.

An additional pipeline marker will be installed in the near vicinity of the ARMCO barrier to signify a change in direction.

The contractor indicated that they would review their work instruction relating to locating buried services, prior to commencing work.

620 Work Practices During the course of a scheduled weekly road patrol a SEA Gas maintenance contractor discovered the un-authorised installation of fencing over the pipeline easement, within 2 metres of the pipeline.

The fencing contractor had previously been inducted by SEA Gas however in this instance the contractor did not request an 1100 Dial Before You Dig asset referral, nor contact SEA Gas, prior to commencing work.

Prior to commencing work on the pipeline easement a pre-start pipeline location was not requested by the contractor.

Indicative placement of pipeline markers along the pipeline easement was relied upon to predict the location of the pipeline during the installation of the fence posts.

SEA Gas investigated the breach in consultation with the contractor, who was re-briefed regarding activities on the pipeline easement which require approval prior to commencement and associated asset location by a SEA Gas representative.

The briefing included an overview of activities which have the potential to compromise safe operations on the pipeline easement.

A site inspection by SEA Gas representatives confirmed that the pipeline and its protective coating had not been damaged during the installation of the fencing.

The contractor indicated that they would review their work instruction relating to locating buried services, prior to commencing work.
