Use of geosystems for coastal and Marine structures to combat erosion Problems - case reference - geosystems at lng Petronet Terminal, Kochi, Kerala (India)

In the recent years the usage of Geosystem has been accepted as an alternative to the conventional protection measures for coastal structures. The failure mechanisms that lead to instability of stacked geosystems are complex. Presently design of Geosystem structures is carried out merely based on data from offshore coastal environment. However the field observations during the execution process of a break water and protective bund undertaken for LNG Kochi, Kerala in S-W coast of the India showed that the externalities caused due to the upland riverine environment effect the stability of the offshore structure.

The above work is treated as a case study to further analyze the effect of the externalities due to the riverine systems on the engineering properties of Geotextile tubes. The in-situ solution methods adopted to overcome these externalities which ensure stability of the structure and measures taken for long term UV protection are brought out through a case study.
