Geotextile tubes were indispensable in the bridge building works of the Lach Huyen Port Project. About 27 km of the material was utilised to construct the containment bund of the 620,000 m3 dredged sediment containment facilities.
Building a Polder Dike using a sand-filled geotextile core with a rock revetment – instead of a rock-filled berm – reduced costs, saved construction time and resulted in a smaller carbon footprint.
No proper design guidelines based on sound science are available for the design of GSC structures. This IADC Young Author Award paper describes on-going research which aims to remedy this.
Geotextile tubes or Geotubes® have been applied in coastal engineering for shore protection and breakwaters, and have been used on land and in shallow water. A new method of filling a continuous Geotube® would allow them to be used in rough and relatively deep water.
The real challenges of building underwater berms in the Caspian Sea were the sensitive environment, a harsh climate, complex local regulations and deep cultural differences
