OWA 2015: Managing successful shutdowns in a deepwater environment
Kayode Ayorinde, major shutdown/SMR coordinator for Total E&P Nigeria, details the entire process, including success factors, in a paper he co-authored with Total Shutdown Preparation Engineer Jude Anavhe.
The deepwater Akpo field, located on the OML 130 license more than 100 km (62 mi) off Nigeria, was brought onstream in March 2009. The field, in water depths ranging from 1,300 m to 1,450 m (4,265 ft to 4,757 ft), consists of 22 oil producing wells, two gas injection wells and 20 water injections wells.
Akpo’s first full field shutdown was executed in 2012 and lasted 34 days. With a scope of work that included the inspection of 44 pressure vessels; 145 defective valve replacements; and the upgrade of the topsides, the subsea UPS and the ICSS, Kayode Ayorinde, major shutdown / SMR coordinator for Total E&P Nigeria, said that the shutdown was deemed a success. More than 390,000 work hours expended without LTI, and 95% of the approved scope of work completed with good health, safety, and environment results.
Ayorinde details the entire process, including success factors, in a paper he co-authored with Total Shutdown Preparation Engineer Jude Anavhe entitled, “Managing successful shutdowns in a deepwater environment - The case of Total Nigeria’s Akpo full field shutdown.”
Ayorinde is scheduled to present his paper Wednesday, Jan. 21, from 14:30-15:00, in the Abora suite of the Eko Hotel & Suites on Victoria Island, Lagos, Nigeria. For more information, please visitwww.offshorewestafrica.com.
