What testing has the SCFB undergone?
From 1995 to 1997 the SCFB underwent in excess of 70 tests; these tests included static load, dynamic load, buoyancy force, sand and gravel tests, duration tests (35 days), extreme cold temperature tests, and obstruction tests. These tests concluded that the barrier never stayed stuck and rose up in all tests. The SCFB remained watertight in all tests.
