2.4 Cathodic Protection Potential Survey
An annual Cathodic protection potential survey of the PCA and associated laterals occurred during
August 2013. 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 potential with respect to a saturated copper/copper
sulphate reference electrode at each test point. The pipeline potential over a 20-hour period was
also recorded at nominally every fifth test point, as required for pipelines subject to the effects of
telluric currents.
Annual Report (PL13) – Port Campbell to Adelaide Pipeline
(PCA) 2013 – 2014 Licence Year
Page 6 of 28
The results of the survey indicated that the PCA and its associated laterals are 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 taken on all corrosion probes and it was identified that the downstream probe at the
Bolivar site required replacement.
The reconnection of the sacrificial anodes originally installed to provide temporary protection during
construction, continues to be successful in reducing the magnitude of voltage variations due to
telluric currents. Consequently these will remain connected to the pipeline.
2.5 Pipeline Location and Referral Services
During the course of the licence year numerous enquiries were received from the free call 1100,
“Dial Before You Dig” asset referral service, for the South Australian section of the PCA. A portion of
these enquiries related to third party work which had the potential to affect the continued safe
operation of the pipeline, triggering further investigation, or an onsite assessment of the proposed
third party activity.
2.6 Emergency Response and Preparedness
During the licence year, SEA Gas undertook the following emergency response exercises:
• Exercise Aotearoa, assessed the continued safe operation of the SEA Gas and Mortlake
pipeline systems while operating from the Backup System Control Centre. The ability to
activate the SEA Gas Emergency Response Plan in response to an incident occurring along
the pipeline system during a building evacuation was also tested;
• Exercise Litoria, assessed emergency response on the Mortlake high pressure gas
transmission pipeline as a result of a pipeline damage scenario during a coating defect
excavation. The resulting activation of the pipeline Emergency Response Plan ensured the
continued safe operation of the Mortlake pipeline system, pending an investigation of the
damage and implementation of a repair strategy; and
• Exercise Timer, assessed out of hours response by SEA Gas personnel, to ascertain how
quickly SEA Gas could realistically resource up in the event of an incident. The exercise
included notification of all personnel in accordance with call escalation processes.
Recommendations arising from these exercises are being addressed and will contribute to the
continuous improvement of 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 2014 / 2015 licence year, SEA Gas intends to host:
• A collaborative emergency response exercise with emergency services providers; and
• A collaborative exercise with the Office of the Technical Regulator and Department of State
Development to test processes for managing off specification gas.

During the course of a site inspection an oily stain was noted on
a patch of gravel within the compound, in the near vicinity of
the Schaffer gas over oil actuator. A subsequent investigation
revealed that an oily mist had been discharged onto the gravel
during venting of the cavity on the main line valve.
� The major causal factor attributed to this incident was
design, as the vent points for the MLV do not cater for
liquids to be captured. Small amounts of liquids can
become trapped in the MLV cavity. The liquids are likely
to be from minor leakage of compressor seals. There was
also an oversight by the maintenance personnel to clean
up the spill, which is standard operating practice.
� The stained gravel was removed from the site
and disposed to landfill.
� Design modifications are being considered to
allow capture of any liquids when venting
MLVs.

During the course of a landholder liaison visit by SEA Gas
personnel, the landholder indicated that he had recently crossed
the pipeline easement with a ripper to install a 32mm diameter
irrigation pipeline to a depth of 400 mm, without seeking
approval from SEA Gas. The separation distance from the twin
350mm diameter SEA Gas pipelines at the crossing point was
confirmed following a site assessment to be 1,000mm.
� The major causal factor attributed to this incident was
‘work practices’. There was an oversight by the
landholder to contact SEA Gas or request a ‘Dial Before
You Dig’ asset location referral (as he had done on
numerous past occasions), due to time constraints
associated with the loan of his neighbour’s ripper and a

During a scheduled easement patrol, a SEA Gas patrol officer
observed that existing fence posts had been removed from the
easement and a fencing contractor was installing a new fence
and working towards the easement. An investigation revealed
that no ‘Dial Before You Dig’ enquiry had been requested and
nor was any prior contact made (or likely to be made) with SEA
Gas prior to commencing work.
Upon investigation it was discovered that a new fence post
would have been installed close to one of the twin 350mm
diameter pipelines on the easement.
� The major causal factor attributed to this incident was
‘work practices’. There was an oversight by both the
landholder and the fencing contractor who did not
contact SEA Gas or request a ‘Dial Before You Dig’ asset
location referral.
� Both parties had assumed that the other had initiated the
appropriate approvals prior to commencing work.
� Both the landholder (reaffirming previous
communications) and the fencing contractor
were advised in relation to the correct process
to be adopted when intending to carry out
work on the pipeline easement.
� Correspondence was sent to both parties,
including pipeline awareness material.
� A SEA Gas Land Liaison representative visited
the landholder.
