2. S. No. in the Schedule DREDGING7 (e)

A Category

3. Proposedcapacity/area/length/tonnageto be handled/commandarea/lease area/ number ofwells to be drilled

Dredging Quantity1.8 million cubic meter(Area 375X420 Sq.m.)

Disposal of dredged spoil(Area 2000X2000 Sq.m)

Latitude 11042’ N and Longitude 790 46’E.Maintenance schedule is proposed near well headplatform (NTP-1) for a draft -12m

The location of the proposed project of MaintenanceDredging and Spoil Disposal Area near NTP-1 is presentedin Fig 1.1.

4. New/Expansion/Modernization Maintenance Dredging

5. Existing Capacity /Area, etc.The draft near NTP-1 platform have gone less than -4mand hence no vessel/ rig is able to approach the platformas on date. The project is precisely to undertakemaintenance dredging to provide a draft of -12 m which isthe minimum requirement to deploy Rig.
