Hydrographic

You will be required to perform the following:

• Conducts hydrographic surveys which include bathymetric surveys, pipeline routes, navigation channel, as-builts of pipeline and offshore structures, rig moves, sonar sweeps for location of pipelines or under-water obstructions, ROV visual inspection, sub-bottom profiling, and AUV operations.

• Participate in operating a range of survey equipment and systems including, but not limited to the following: Side Scan Sonar, Multi beam, Positioning, AUV, Magnetometer, ROV, Seismic, USBL, Sound Velocity and Seabed Sampling Equipment used on survey vessels within the offshore concession area with minor assistance from senior Personnel.

• Conducts oceanographic field investigations requiring use of sophisticated electronic sensors for measuring tides, temperature and salinity in marine environment. Participate in detached survey operation on small boat, Vessel-Of-Opportunity (VOO), and Rig move operations.

• Participate in positioning of an offshore vessel using above and underwater systems under the guidance of Senior Personnel. Identify the various positioning methods (GPS, DGPS, RTK, USBL) of positioning surface and sub-surface vessels/vehicles offshore.

• Participate in operating various hydrographic survey equipment under the guidance of Senior Personnel.

• Understand the various hydrographic data sets impacting on the preparation of an offshore survey, including historical information. Under guidance, performs all types of hydrographic surveys aboard survey vessels and small boats.

• Under the supervision of Senior Personnel conducts oceanographic field investigations involving installation, calibration and recovery of tide gauges, current meters, CTD probes for Temperature and salinity measurement and thus Sound Speed profile preparation. Understand the various components and interaction of the multiple observations essential for understanding the physical oceanographic structure and its sediments.

• Describe the general scope of ROV operation and identify the different ROV roles and their assignments. Perform the role of Pilot, Navigator and Observer during ROV operation under direct supervision from Senior Personnel.

• Under supervision participate in data processing for all hydrographic survey operations.
