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:

387 Work Practices Incident Description: Unauthorised fencing across the pipeline easement and an unauthorised gate and post installation on another nearby section of the pipeline easement, that had resulted in removal of a pipeline marker sign.
Safe Work practices for excavation on the pipeline easement were not followed. The property owners and manager were aware of the pipeline location; however neither the property owners, nor the property manager, requested a Dial Before You Dig asset referral. SEA Gas was also not consulted prior to the excavation on the pipeline easement or the relocation of the marker post.
Written advice was provided to the three joint owners of the property, reinforcing the need to seek approval prior to commencing activities on the pipeline easement which involve excavation to a depth greater than 300mm.
SEA Gas offered to provide the property owners and property manager a pipeline awareness session.
The resident owner and property manager were re-briefed regarding activities on the pipeline easement which require approval from SEA Gas prior to commencement. The briefing also highlighted activities on the pipeline easement, which have the potential

538 Work Practices Incident Description: Unauthorised trenching of a polyethylene water pipeline across the pipeline easement, to a depth of 500mm by a third party contractor.
When requesting a Dial Before You Dig (DBYD) asset referral, the pipeline contractor entered the incorrect location for the proposed work site. The SEA Gas pipeline was not in the identified work area.
Prior to commencing work, the pipeline contractor did not take note of the pipeline marker signage in the near vicinity of the work area, relying solely on the information received as a result of the Dial Before You Dig request.
The property owner and the contractor were briefed regarding activities on the pipeline easement which require approval from SEA Gas prior to commencement. The briefing also highlighted activities on the pipeline easement, which have the potential to compromise safe operations.
SEA Gas instructed the contractor on how to identify a work site correctly in the DBYD system.
A site inspection by SEA Gas representatives confirmed that the pipeline and its protective coating had not been damaged during the installation of the polyethylene pipeline.

685 Work Practices Incident Description: Water bath heaters were refilled with water containing corrosion inhibitor solution following inspection and repair of the internal fire tubes. As the heater reached its operating temperature of 55°C, the water expanded and subsequently overflowed, discharging into a bunded collection drum and onto the ground beneath each heater.
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.
