Operations at the SeaRose floating production, storage and offloading (FPSO) vessel are suspended, with all production wells secure, after an oil release.

 

Operations will remain suspended until a full inspection of all facilities is completed and Husky has received the support and approval of the Canada-Newfoundland Offshore Petroleum Board (C-NLOPB).

Production was shut in at the White Rose field Thursday, November 15 due to operational safety concerns resulting from severe weather. Once conditions had returned to normal operating parameters on Friday, November 16, and safety checks were completed, the process of resuming operations commenced. The release occurred as we were in the process of resuming operations.

A remotely operated underwater vehicle (ROV) survey has shown the release came from a subsea flowline connection. This survey did not observe any oil at the source and, since Friday, November 16, no additional oil has been observed at the surface. The oil released Friday, November 16 had dispersed. No sheens have been observed since November 18.

An investigation into the cause is underway. We will cooperate fully with the C-NLOPB and other regulatory authorities, to ensure government, other offshore operations, and the public are kept informed.

Our focus remains the safety of our people and the environment.

Jan. 11, 2019

For the last several weeks, we have been working to complete inspections, revise processes and give ourselves, the certifying authority and the regulator, confidence that we are able to proceed with various operations in a safe and environmentally responsible manner.

Pending completion of our due diligence and regulatory approvals, we anticipate moving on some key activities in the coming days and weeks including:

  • Recovery of the flowline connector and plugging the flowline
  • Leak testing at the Central Drill Centre (CDC)

While we still have some final verifications to complete, we could begin flushing and leak testing of the Central Drill Centre as early as this weekend or Monday. 

Flushing/Leak testing of Central Drill Centre

Leak testing of the Central Drill Centre is a necessary step to assure us, the regulator, and our certifying authority that it is safe to resume operations in this area.  This will require us to circulate reservoir fluids including oil, gas and water from the production flowlines back to the SeaRose. The flowlines will be displaced with seawater prior to testing.

Our inspection regime has been completed, and certifying authority verification of flowlines, moorings, topsides and hull is in place. 

We have completed a risk assessment, reviewed start-up procedures and updated our adverse weather guidelines.

The testing regime has been reviewed by our certifying authority, DNV-GL, and provided to the regulator. As part of the testing regime, we will have ROVs in the water to monitor for any leaks. 

The Central Drill Centre is on its own independent loop to the SeaRose production facility and is not related to the flowline network that supports the South White Rose Extension where the November incident occurred.

Recovery of flowline connector and plugging of flowline

We continue to focus on integrity verification at the South White Rose Extension, including recovering the flowline connector and plugging the flowline.  This remains a priority for both us and the regulator.

The flowline itself is not damaged and will remain on the seabed for re-connection.  We have had ongoing meetings with the regulator this week to finalize our approach, and in support of this will conduct a tabletop exercise Friday, Jan. 11 with the C-NLOPB, Coast Guard and others to walk through and refine the process and necessary mitigations.

We will provide additional information once our plan is finalized and approved by the regulator and we have a weather window to complete the work.

We are committed to ensuring all the appropriate checks and balances are in place for this work to proceed safely and with minimal environmental impact. Key activities have been assessed for risk with an accompanying table top exercise to walk through potential challenges in the process. In addition, "hold" points have been built into our processes, and, with the regulator and relevant federal agencies, appropriate mitigations and oversight have been identified.

Subject: Update Atlantic Region offshore response and investigation update

On Friday, December 7, Husky submitted its preliminary report on the November 16 oil spill to the Canada-Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB). Husky's preliminary investigation indicates the release happened when a flowline connector failed near the South White Rose Extension drill centre, approximately 350 km east of St. John's. Husky's final report will include engineering analysis of the flowline connector once it can be brought ashore.

The incident happened while warm crude from the SeaRose was being circulated through the subsea network to warm up the flowlines prior to restarting production. The investigation to date has confirmed there were two fluid releases containing a mix of oil, water and gas. Our initial estimate of total volume released is unchanged at 250 cubic metres (250,000 litres). It is an engineering estimate based on the flow rate of the line and the time fluid was known to be flowing. The investigation continues to assess the mix of fluids released.

The initial release occurred during the approximately 20 minutes offshore teams were troubleshooting a drop in flowline pressure. A retest led to a second release lasting approximately 15 minutes.

We are deeply sorry for the incident and are committed to learning from it and putting measures in place to ensure it does not happen again.

We have identified, and are already taking steps to address, areas for process improvement especially around the areas of:

    • Trouble shooting;
    • Non-standard or infrequent conditions; and
    • Adverse weather and challenging conditions

We are working on improving how we identify and manage non-standard or infrequent operating conditions. We are also revising our Adverse Weather Policy to add more formality around the process of restarting production.

We have implemented enhanced oversight on critical activities to raise the awareness of potential risks and providing team back up.
We continue to work with the regulator on a plan to recover the failed flowline connector and plug the flowline and are cooperating fully with its investigation.

No sheens have been detected since November 18.
