Deep Panuke Project Description - Encana

Requirements for eventual removal of facilities will be taken into account during detailed design.Although regulatory requirements could change prior to the time of decommissioning and abandonment,current practices would see the facility degassed, degreased and cleaned to applicable standards, theMOPU towed to another location for re-use or retrofit, the wells abandoned and conductors cut belowthe seafloor, and the pipeline, flowlines and umbilicals flushed, cleaned, and abandoned in place. Thepotential presence of contaminants that could be encountered during recovery and transportation of thefacilities will be taken into account. Potential reuse of the MOPU will be considered on an economicbasis.Wells will be abandoned in compliance with applicable drilling regulations and according to standardindustry practices.With the exception of the pipeline, onshore facilities will be removed and the land restored inaccordance with applicable regulations. Buried onshore pipelines will be flushed, capped, andabandoned in place. The onshore pipeline RoW will be allowed to return to a natural state. Any abovegroundstructures associated with onshore pipelines will be removed. A Decommissioning Plan will bedeveloped for the Project, which will provide detailed procedures for decommissioning onshorefacilities.2.6 Project ScheduleThe Project Offshore Strategic Energy Agreement (OSEA), signed in June 2006, initiated the start of thenext Project phase. Consisting primarily of the regulatory approval process, major contract tenderingand negotiations, and a field centre bid competition, this phase is expected to be completed in the thirdquarter of 2007, with an expectation of project sanction in the third quarter of 2007. Assuming sanctionand after contract awards, the Project will engage in detailed engineering and procurement. Subsequentonshore fabrication at existing facilities will occur prior to installation offshore.Hull and topsides fabrication is scheduled to commence third quarter 2008, with the MOPU hull andtopsides ready for at-shore integration first quarter 2010.It is anticipated that the onshore and offshore sections of the export pipeline will be constructed either in2009 or 2010. The tie-ins to the MOPU and to either the M&NP facilities or to the SOEP pipeline willbe completed after the MOPU and the export pipeline installation is complete. Hook-up and offshorecommissioning activities will commence third quarter 2010 once the MOPU has been transported to thefield centre. First gas is anticipated to be produced in the fall of 2010.Well construction and completions will be completed with a separate mobile offshore drilling unit andwill be scheduled between 2008 and 2010.Deep Panuke Volume 4 (Environmental Assessment Report)• November 2006 2-45
