Seabed or Sub-Seabed Mapping
Seabed engineering and oceanographic
studies were carried out to delineate the information regarding seabed morphology,
seabed and sub-seabed geology etc. after the collection and subsequent analysis
of bathymetry, sub-bottom profiling and Sidescan data. These form a
part of the feasibility study for the construction of Ports, Jetty-structures,
SPM and LFP locations etc. Seabed mapping forms an integral part of
pre- and post-dredging activities in port and harbours.

Pipeline Monitoring
Pre-lay and post-lay pipeline surveys
were conducted off Dahej during October 2004. The surveys consisted
of Parametric sounding to find out the extent of pipe burial with respect
to the seabed. Side scan sonar imaging was carried out to strengthen the
Parametric Sounding results.

Search Surveys
Search surveys were carried out (1) for ISRO (through DOD) to locate the remains of GSLV, off Sriharikota,
2) for ICMAM, to locate a current meter – tide gauge unit, off Ennore port at about 20 m depth, 3) for ONGC, to locate three
Oil/Gas Well-Heads in deep waters – depth varies from 200m to 500m, 4) to
locate archaeological objects at Poompuhar.
