Actemium Oil & Gas Maintenance



USAN Project was a new field development in 750 m water depth and 100 km South of the Nigerian coast.
USAN has been developed with 42 subsea wells connected to a 2 MMbbls storage FPSO via 2 production loops, 2 water injection lines and 1 gas injection line.
The OML 138 block in Nigeria contains the USAN field which started production in February 2012.

On the FPSO USAN project Actemium Oil & Gas Maintenance and Pace had provided respective expertise.

Actemium Oil & Gas Maintenance had executed the Maintenance & Inspection Engineering Contract:

  • Execution of maintenance engineering work in order to define the maintenance strategy, programme and schedule based the criticality review and Reliability Centred Maintenance,
  • Execution of inspection engineering work to check the USAN assets and define the inspection strategy, programme and schedule using Risk-Based Inspection (Fame+ Software) for pressure equipment
  • Preparation of templates for data integration into the computerised maintenance & inspection management system (CMIMS),
  • Issue of maintenance & inspection manuals and first-level maintenance procedures,
