00:00Thousands of tons of ocean water press relentlessly against the massive steel barrier.
00:05Massive dry-dot caisson gates are engineered to deflect slightly under immense hydrostatic pressure.
00:12Rigid concrete lacks the flexibility to safely withstand the intense bending stresses of this ocean pressure.
00:19Engineers design hollow chambers for buoyancy, while the steel structure is engineered to safely flex under immense pressure.
00:26This controlled deflection compresses the seals, utilizing hydrostatic pressure to secure a water-tight barrier.
