LNG Site Consolidation and Tank Seismic Analysis

Design and Analysis

SC Solutions performed soil consolidation analysis, foundation feasibility and the seismic study for large LNG/LPG storage tanks to be built in soft coastal soils. The study included site consolidation numerical analysis, and considered the  wick drains and surcharge to determine the drain spacing, surcharge loading and surcharge time to achieve a degree of consolidation that would permit the tanks to be built without the detrimental effects of additional long term settlement. Long-term foundation settlement under tank operational loads and preliminary tank seismic studies were also carried out following site consolidation analysis.

Future work may  include the monitoring of the construction settlement, and the calibration of consolidation models to refine and recompute consolidation to determine the construction schedule for removing the surcharge and turning the site over to the tank EPC contractor.
