Enayam Port

Tamil Research Institute
RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
To sum up, the dominant waves come from the south-south western direction, and for 200 years of return period,
a wave height of 5 meter with a peak period of 11,5 seconds have been taken for the preliminary design of
port structures.
More detailed information of this study is enclosed in Annexure 3: Metocean analysis - Wave propagation.
7.2. BATHIMETRIC DATA
In order to have good bathymetric information of all the possible locations, a series of nautical charts -both in
paper and electronic (ENC) - have been purchased through MaxSea TimeZero software.
Specifically, the following charts have been used:
• 2048-Kolachel Anchorage (1:30,000)
• 222-Quilion to Colachel (1:150,000)
• 223-Colachel to Manappad (1:150,000)
• 7365-Cape Comorin to Pamban (1:300,000)
• 7362-Cochin to Cape Comorin (1:300,000)
A complete bathymetric map has been developed combining all the charts, leading to a chart like the following
(see drawing-01 for more detailed info).
7.3. TOPOGRAPHIC DATA
