Hydrography / Bathymetry

Kordil performed bathymetric / hydrographic survey over an area of 1 million hectares as of Jan 2020. Bathymetry is one of Kordil's field of competence in offshore industry. Kordil is not only performing surveys, also engineering offshore survey products such as single beam echo sounders (KBS200 and KBS30200) and developing software packages such as Kordil Bathymetry Studio which are extensively and widely in use in local market. Some of our fields of competence in bathymetry:

  • Bathymetric surveys for ports, harbours, routes and construction
  • Integrated multibeam, singlebeam, side scan sonar, backscatter and water column surveys
  • High precision seabed topography and obstacle detection surveys
  • Low cost dual and single frequency singlebeam bathymetric surveys
  • Bathymetric surveys for ponds, discharge pools, rivers, channels with unmanned surface vessels
  • Multibeam scanning with ROV for underwater inspection

High Resolution Bathymetry with Multibeam Echosounder

Kordil has high resolutions multibeam echo sounders in their inventory to perform high resolution seabed mapping from 0-600 meters depths. Kordil utilizes Norbit IWBMS series 200-400-700 kHz bandwidth multibeam echosounders with snippets, water column, backscatter and side scan sonar capable systems that are proven to be world class and top grade systems. With wide scanning angles, Norbit can scan whole of a trench starting from coastal zone down to the bottom (210 degree scanning angle, which is 15 degrees upward from sonar head). With mobility of Norbit Multibeam systems, it makes it easy to install systems on any platform such as manned rubber boats, as well as big ships.

The systems use top class INS systems integrated, and provide very robust and reliable results in all applications that we are carrying out.

Bathymetry with Singlebeam Echo Sounder

With extensive availability of several echosounder systems, Kordil provides low cost bathymetric surveys without much compromising the seabed topography. Singlebeam bathymetry may not be very suitable to measure wallets and low spots, but is very convenient to use for detecting high spots, and performing good and reliable results in flat areas. Kordil offers singlebeam surveys to most of the clients because it is low costs and meets with so many costumer's requirements.

Kordil is manufacturing and distributing KBS200 single frequency and KBS30200 dual frequency echosounders which are made in house, and reduces the survey costs a lot. Kordil also uses its proprietary software package Kordil Bathymetry Studio which was also developed in house to serve customers' and partners' needs with survey grade, industry standard complete survey package. The system is extremely mobile and fits inside a single transit case, with whole installation frames and apparatus including space for GNSS but not only for Sound Velocity Profiler.

The systems developed by Kordil were always tested in real projects many times before being shipped to customers. So far whole systems were delivered with 100% customer satisfaction and with a return policy. So far, over 10 years, no systems were recorded as returned.
