Nigeria has the 8th largest proven natural gas reserves in the world, but ranks only 29th in production. The proposed Brass Island liquefied natural gas (LNG) plant is a critical step toward the country capitalizing on this important natural resource. But building this complex facility to international standards while using local resources has proven to be a significant challenge.
Schnabel’s field engineers were instrumental in the success of the project by working with the local Nigerian drilling crews to collect samples in accordance with the project’s strict quality requirements and ASTM standards. We produced a Project Quality Plan and assisted in the preparation of the Subsurface Investigation Plan, Health and Safety Plan, and Security Plan to ensure conformance to project specifications. We also oversaw the testing of undisturbed samples collected in the borings and transported to a U.S.-based laboratory.
To obtain high-quality geotechnical information for the design of foundation systems for two LNG trains, Schnabel provided two onsite geotechnical engineers, one of whom also served as Quality Control Manager. During the 18-week-long subsurface exploration program, test borings were drilled to depths up to 450 feet in the complex delta geology. Much of the massive infrastructure for this project has been constructed at a cost of over $1 billion.
