Carrying out Hydro Graphic Survey /Bathymetric Survey

Mobilization of Tools and Equipment from Laboratory to Site for conducting Hydro Graphic Survey/Bathymetric survey work.

Bathymetry Survey:- The Bathymetric Survey shall give full and continuous, 100% coverage, high resolution data. All soundings and subsequent contours shall be reduced to local chart datum by observed tide. Sound velocity, Heave, pitch and roll corrections shall be measured and applied. The survey will be done using multi-bean echo sounder for the area of 600x1000 m (0.6 sqkm) with an overlap of 30%. The swath width approx 3 times the depth. Ship speed 3-4 knots. If depth=10m, Swath=30, Line spacing=25m, Total Line Km=24 km SVP to be collected during Survey time (max 2 per day)

Sub bottom Profiler: - To establish the geometry, structure and configuration of the geological strata, sub bottom profiling survey by a suitable Pinger / Chirper/Boomer/ Sparker sub-bottom profiler shall be performed with a system suitable to giving minimum penetration of 10m or bedrock, whichever is shallower. The resolution shall be of the order of 15 cm at the surface. Considering the longer shallow water section and sandy bottom is expected, interface equipment with profiler to improve data quality shall be implemented. 10m Line spacing, 60 lines, Line Km=24 Siltation studies at the site i.e, range area, jetty area and required areas

Side Scan Sonar: - Sea bed imaging shall be carried out with dual frequency side scan sonar with frequency range of 100kHz and 500 kHz or 400kHz and 900kHz for sea floor mapping/ sea bed morphology and seabed characteristics. To conduct Side scan survey using DGPS system and side scan sonar equipment. To be done for the area of 600 x 1000 m (0.6 sqkm) with an overlap of 30%. The swath width approx 3 times the depth. Ship speed 3-4 knots. If depth=10m, Swath=30, Line spacing=25m, Total Line Km=24 line km

Oceanography Survey: Measuring water flow/ current velocity at designated depths from the water surface. Currents speed and direction data should be collected using Acoustic Doppler Current Profiler (ADCP) for period of 30days. The location of ADCP should be such that minimum water depth of 10m is available at that point and the point should lie on the centre-line of the survey corridor. Tidal stream rate and direction measurements should be made with an uncertainty of less than ± 0.1 knot and ± 50(with respect to true north) respectively, both at 95% confidence. The positional uncertainty of moored current metres and ADCP measurements should be less than ± 20m and ± 2m respectively. The upward looking ADCP to be moored 1-2m above the see bottom 1200/600 kHz Frequency to be used. Both Current (averaged for 10 min) and wave data (burst~1 Hz) to be collected. The Current velocity (at Surface level, half of the depth & above sea bed) are to be observed. Their positions & value are to be plotted on the chart and details are to be mentioned in the report.
