SAN ANTONIO– A presentation by Sergio Porciuncula of Petrobras America Inc. that focused on a problem experienced with a free-standing hybrid riser on the Cascade-Chinook project drew a record crowd of 500-plus attendees Wednesday morning at the Subsea Tieback & Exhibition Forum currently being held in San Antonio, Texas.  

In 2011, one of the free-standing hybrid risers (FSHR) on theCascade-Chinook project experienced a problem in its tether chain system. Porciuncula discussed how an emergency response plan was implemented and successfully executed to secure the safety of personnel, the environment and the production system.

The presentation also described the solutions that were developed and executed post stabilization to resume production on both fields. Production on the Cascade field was enabled by replacing the existing chain tethers and installing additional synthetic rope tethers to the other FSHRs.

Production was resumed on the Chinook field by interconnecting a new flowline to the Cascade production system and installing a subsea pig launcher to regain full functionality.
