SETHUSAMUDRAM SHIP CANAL PROJECT

 

TERMS OF REFERENCE

 

1.1  Assignment – 1 : To establish Techno-Economic Viability of the Project :

 

(i)    To study future traffic potential over a short, medium and long term time horizon (2020 AD). in terms of volumes of cargoes in tonnage and also number, size and category of ships like  container, dry liquid bulk and other types of vessels taking into due consideration the future economic growth in the liberalized economic regime, GNP/GDP growth, hinterland developments, likely competition from other modes of transports like pipelines (for liquid bulk transport). Railways and Roadways, growth of nearby national and regional ports, national targets of shipping over the time horizon of assessment of traffic potential, prospect of development of container ‘hub’ port(s) in the vicinity like Tuticorin, Cochin etc., with the objective to establish the need for Sethusamudram Ship Canal Project for use by ships which are likely to be deployed in carrying the assessed sea borne trade.

 

(ii)   From the above, to arrive at the optimal design size viz. DWT/TEUs, LOA, Beam, Draught (max), for the design of canal from economic considerations; while doing so, to examine the alternative of moving in large vessels (like VLCCs, modern bulk carriers) on the existing routs (going round Srilanka) and operation of relatively smaller vessels through the proposed canal.

 

(iii)  To study the earlier reports on Sethusamudram Ship Canal Project, especially the Laxminarayan’s Committee Report (1983) and the Initial Environmental Examination (IEE) Report(1998), by the National Environmental Engineering Research Institute (NEERI), Nagpur, which made an initial examination of the environmental aspects related to the project based on the limited data already available/collected.

 

         To start with, critically examine the new alignment of canal suggested in the NEERI’s Report, with reference to environmental factors, navigational aspects, morphological aspects, sedimentation likely to be induced by the cross currents in the canal after its creation and during operation with a view to establish, prima facie, suitability of the alignment.

 

          If the alignment is found, prima facie, to be not suitable suggest any changes/modification taking into account various aspects such as sea bed movements sedimentation, dredging, navigation, security considerations, proximity of the medical line between India and Sri Lanka etc.

Top         

 

(iv)  Based on the suggested, modified alignment, assess the required marine, geophysical, hydrographic and hydraulic (mathematical-simulated ) investigations required to be carried out to confirm the modified alignment, the dredge depths, canal dimensions, quantum and material of dredging, disposal grounds (offshore and onshore) etc.
