A stable platform on soft ground

Kochi refinery in Kerala, India needed a stable platform on which to operate a large crane in the assembly of new infrastructure. Tensar suggested their Stratum system but needed a way of predicting crane settlement to ensure safe operation of the plant.

From our experience of simulating mechanical stabilisation by geogrids in FEA we were able to simulate the Stratum system on the local ground conditions to demonstrate that crane settlement and tilt would be within safe limits.

Highlights

• 3D FEM model of crane platform, Tensar Stratum system and soft ground.

• Application of platform loading for various crane lifting operations.

• Predicted crane settlement and tilt within safe limits.
