Project Details

Title: Rehabilitation / Upgrade of Sapele Metering Station

Client: Aveon Offshore Limited / Seflam SGL / Nigerian Gas Company NGC

Location: Sapele, Nigeria

Date: 2024

description

The Metering Station has been in operations for over 30 years. No major overhaul/upgrade of the station has taken place since commissioning.

NGC intends to carry out rehabilitation/upgrade of the station in view of the development of gas infrastructures and growing demand for natural gas in the country. A FEED project has been carried out to define baseline specification, detailed scope of works, etc. to progress the rehabilitation/upgrade works and develop detailed engineering deliverables necessary to actualize the Procurement, Construction and Installation Works.

The Station was designed for a pressure of 100 barg with supplies from 2 inlet sources, namely 18” inlet line from NGC Oben Metering Station and 16” inlet line from Sapele west.

The station is currently facing the following challenges: 

  1. Existing scrubbers are over 30 years old in operation and vessel mechanical integrity needs to be checked.
  2. Facility is controlled manually and thus the need to be automated
  3. Inlet and Outlet ESDVs needs to be automated
  4. Control room is not available. There is a need for new up-to-date control room
  5. Barton Meters on the Metering Skids is malfunctioning
  6. Existing condensate tank design is not adequate
