Husky Energy issues field update

From Husky Energy
Issued January 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 connected into the flowline network that supports the South White Rose Extension.

Recovery of flowline connector and plugging of flowline

We continue to focus on integrity scopes 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.
