Session 3: Neptune Spar Life Extension
Date & Time
Wednesday, February 5, 2020, 3:15 PM - 3:45 PM
Originally installed in 1996 with a 20-year life span, the Neptune Spar is still producing, and currently undergoing efforts for its second life extension. In 2015, while owned and operated by Noble Energy, Neptune was granted a 3-year life extension until the end of 2019. Now, while owned and operated by Fieldwood Energy, Neptune is seeking an additional 5-year life extension until the end of 2024. Production has been steadily declining from the Swordfish subsea tieback field, which led to Noble Energy being comfortable with decommissioning at the end of 2019. However, once Fieldwood acquired the asset, with the help of some topsides and subsurface optimization by the engineering and operations personnel, the decline curve has decelerated. This, in combination with the low operating cost brought on by the new Fieldwood Energy regime, were the driving factors in seeking an additional life extension. The life extension efforts include navigating the regulatory and classing requirements of BSEE, USCG and ABS, as well as the technical safety assessments necessary to justify continuation of keeping personnel onboard the aging facility. The Neptune Spar is extremely robust, and continues to prove itself year after year with what has now become a very active mechanical integrity inspection schedule, given its age. The task at hand is proving to the regulators by engineering analysis and inspection records that the Neptune Spar is capable of withstanding another 5 years of being out in the Gulf of Mexico, with everything that the environment is capable of bringing in that time period.
