Enayam Port

Tamil Research Institute
RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
A north-south oriented slope breakwater has been designed next to the bridge to protect the berths from waves
coming from the west, typical of the monsoon season.
In phase 1 of the port development, the bulk and container terminals are located in the deepest area, while the
berths for auxiliary or smaller vessels are located along the slope breakwater with north-south orientation.
Phase 2, corresponding to the year 2025, requires the extension of the main breakwater toward the south-east
by around 1,600 meters, and the same length for the container berth.
In Phase 3, extending the main breakwater was not considered to be an appropriate option because it would
greatly affect the coastal dynamics of the beach. Therefore, the container terminal will be expanded next to the
private fishing port breakwater. Even though this solution is simple and inexpensive from the maritime point of
view, land accessibility would be problematic because a road link to the land side of the port would have to be
built, either running through the town or surrounding the cape along the coast.
