Industry Notifications

This notice is an update to GIC notices 000042 and 00039 which relate to the unexpected mechanical issues associated with one of the engines on the construction support vessel that is required for the proactive inspection and maintenance work on the subsea pipeline at the Pohokura natural gas field (GIC notices 000014 and 000028). This notice also refers to the onshore production station outage at Pohokura (GIC notice 000003).

Repairs to the engine of the construction support vessel contracted to undertake the inspection and maintenance work are currently being executed in Nelson. These construction support vessel repairs are expected to be completed in the window of February 29th to March 7th, depending on the scope, after which the vessel will mobilise to New Plymouth to commence the planned inspection and maintenance work on the undersea pipeline.

OMV has reassessed the schedule risk associated with the undersea pipeline inspection and maintenance project, including vessel and equipment mobilisation, adverse weather and execution of the project work scope. On a risked expectation basis, OMV anticipates the subsea pipeline inspection and maintenance work will require, in total, an outage duration of approximately 45 days, which is approximately 25 days of actual works, and 20 days of allowances (weather, sea state, subsea visibility etc). These estimates are subject to ongoing planning and it is possible that the work may identify further remedial actions that require additional offshore gas production outages.

The pipeline outage is planned to start close to the start of the Pohokura Production Station outage. The Pohokura Production Station outage is required for a 4 yearly statutory inspection and the expected timing of the outage remains between the 11th and 24th of March.

A further update will be provided on or before the 28th of February 2020.

Nova Energy on behalf of Todd Energy advises the deferment from planned maintenance at Mckee - Mangahewa production station, from the 4/3/2020 to 6/3/2020 and again from 12/3/2020 to 14/3/2020, has been mitigated and will no longer reduce daily production volumes.

This notice is an update to the notice issued on the 7th of February 2020 (GIC notice 000039), relating to the proactive inspection and maintenance work on the undersea pipeline and onshore production station at the Pohokura natural gas field.

The specialised work vessel (the Normand Baltic) is enroute to Nelson, due 15 February 2020, where engine repairs will take place. Repairs are expected to be completed by 27th February, after which the vessel will mobilise to New Plymouth.

A revised expectation timing and duration for the outages associated with this project are being evaluated based on latest vessel repair timing.

A further update will be provided on or before the 21st of February 2020.

OMV New Zealand Limited advises the following:
1. Work relating to the scheduled reduction in deliverability on 24 February (as per notice 000037) has now been postponed so to coincide with the planned outage at Pohokura Production Station (11-24 March , as per notice 000003).

2. With regard to notice 000034, we provide the following update:

Previous:
2-3 March, Well Maintenance, estimated reduction 25-40 TJ/d

Update:
3-4 March, Well Maintenance, estimated reduction 25-40 TJ/d

OMV New Zealand Limited advises of the following update to notices 000031 and 000033 issued on 8 January and 23 January 2020 respectively. The POW-2 well has now returned to levels that it previously produced at. We therefore advise that this period of reduced deliverability has ended.

This notice is an update to the notice issued on the 18th of December 2019 (GIC notice 000028), relating to the proactive inspection and maintenance work on the undersea pipeline and onshore production station at the Pohokura natural gas field.

Execution of the planned work requires a specialised work vessel to be mobilised from Singapore. Mobilisation commenced in late January and while on is journey to New Zealand the vessel suffered mechanical issues.

This has the potential to change the schedule of operation and OMV is currently evaluating options to minimise the impact on the timing and duration of the pipeline outage during the remediation work.

A further update will be provided on or before the 14th of February 2020.

OMV New Zealand has previously announced that it will undertake proactive inspection and maintenance work in 2020 on the undersea pipeline at the Pohokura natural gas field (announced on the 18th of October 2019) and also at the onshore production station (announced on the 29th of July 2019).

In those announcements we identified that during the work on the Pohokura production station all gas production from the Pohokura field would be shutdown between 11 and 24th of March 2020. It was also identified that the pipeline inspection and maintenance work was still in the planning phase and that there was a risk that the pipeline would need to be shutdown to complete the required work.

Planning for the pipeline outage is now materially complete and to safely and efficiently execute the required work the undersea pipeline will need to be shutdown close to the start of the production station outage (11 March 2020) and for one to three weeks beyond the end of the production station outage. An approximate start date and a range of durations is given as the work is dependent on mobilisation of a suitable vessel from overseas, weather, sea state and subsea visibility. It is however possible that the inspection may identify further remedial actions that require additional offshore gas production outages. When the pipeline is shutdown and the onshore production station is operating, the onshore wells are expected to be available to flow.

Beach Energy advises that due to low demand for gas and a trip on the hot oil heating system there has been an reduction in Kupe production from 72.5TJ/day to 40TJ/day for Wednesday 18th December

OMV New Zealand has announced it will be undertaking proactive inspection and maintenance work next year on the undersea pipeline at the Pohokura natural gas field. The flexible pipeline connects the Pohokura offshore wells and platform to the onshore production station. The field also produces natural gas from onshore wells.

OMV became the operator of the field in December 2018, and since then OMV has undertaken a review of 2018 outage event ahead of the mandatory pipeline recertification due in mid-2020. As a result, OMV will undertake a full pipeline inspection and any necessary maintenance work in Q1 and Q2 2020. The work is currently in the design and planning phase. Its scope will be finalised, in conjunction with endorsements by the pipeline certifier, by December 2019.

Except during the separate Pohokura production station maintenance work announced by OMV on 29 July 2019, the onshore wells would be expected to be available to flow during the pipeline inspection programme. It is however possible that the inspection may identify remedial action that requires offshore outages in order to undertake the work. The exact duration and timing of any offshore shutdown periods will remain subject to the final plan meeting regulatory requirements, as well as operational and weather related impacts. The safety of people, environment and the assets, will be paramount throughout the campaign.

As a transparent operator, we will communicate with market participants to ensure clear notification in advance of any potential impacts.
