� Internal and External inspections of all pressure vessels;

� Replacement of compressor station package seals at Coomandook; and

� Tapping and plugging of vent stack holes at scraper station vents.

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.

Page 6: Port Campbell to Adelaide Natural Gas Transmission Pipelineenergymining.sa.gov.au/__data/assets/pdf_file/0004/... · Port Campbell to Adelaide natural gas transmission pipeline (PCA)

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.

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

Practices

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.
