Cathodic Protection Potential Survey

An annual cathodic protection potential survey of the PCA and associated laterals occurred during August 2011. 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 PCA and its associated laterals was fully protected in accordance with the protection criteria defined in Section 2.2 of AS 2832.1.

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.

2.4 Pipeline Location and Referral Services

During the course of the licence year, 592 (44% increase from the previous year) 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. In response to these enquiries, 334 (38% increase) were deemed to have a potential to affect the pipeline and were subject to site assessment.

2.5 Emergency Response & Preparedness

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

Exercise Broadview (7 September 2011, a combined exercise with South Australian emergency services to assess the critical incident response of a pipeline incident within an urban area);

Exercise Cape Nelson (17 April 2012, a combined exercise with SA & Vic Police, CERT Australia, ASIO, emergency services and Wannon Water (conducted in Warrnambool, Victoria) to assess the critical incident response to a cyber-threat); and

Exercise Vulcan (21 June 2012, a combined exercise with Epic Energy and regulatory representatives (DMITRE and Office of the Technical Regulator) to assess emergency response interoperability during an incident impacting the Moomba to Adelaide and Port Campbell to Adelaide pipelines simultaneously).

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 2012 / 2013 licence year, SEA Gas intends to host:



A desktop emergency response exercise for SEA Gas employees to ensure familiarity with recent changes to the SEA Gas Emergency Response Manual (TECH-MAN-011) and Crisis Management Plan (PR-PR-002) ; and

There is no written procedure for re-filling ‘cold’ water bath heaters following process tube removal.

Not all water bath heater vent points enable the capture of corrosion inhibitor solution overflow.

Develop a procedure for water bath heater corrosion inhibitor solution management and train maintenance personnel in its use.

Review adequacy of overflow capture and containment.

Under Investigation
