The need for continuous maintenance dredging has serious budgetary impacts for the Cochin Port Trust (COPT). Therefore Cochin Port Trust assigned Antea Group, IIC technologies and Stema Systems to collaborate on a study for the analysis of the siltation processes and to assess the feasibility to implement the nautical depth concept. The latter signifies to investigate the nature of the fluid mud seabed and determine to what extent vessels can sail through and manoeuvre in it.

Multi frequency 2D phased array transducer
Patent number: 10054681
Abstract: Improved two-dimensional planar array transducer and beamformer apparatus and methods. In one embodiment, the two-dimensional planar array transducer is capable of simultaneously or sequentially forming multiple acoustic beams in two axes and at two or more widely separated acoustic frequencies from a single flat planar array transducer. The transducer planar array consists of two or more electrically and acoustically independent two dimensional planar transducer array structures operating at different frequencies that are physically integrated onto a single multi frequency configuration. In an exemplary embodiment, a second higher frequency transducer array is positioned within the aperture area of a lower frequency planar array transducer. Methods of using the aforementioned two-dimensional planar array transducer and beamformer are also disclosed.

Acquatic velocity scanning apparatus and methods
Patent number: 9823104
Abstract: Apparatus and methods for velocity scanning in, e.g., bodies of water. In one embodiment, a scanned one-dimensional transducer array Doppler sonar arrangement is used to remotely measure both vertical and horizontal profiles of a river or channel along-stream water velocities within a cross-section of the river/channel from a single side-mounted sonar.

Sub-array transducer apparatus and methods
Abstract : Apparatus and methods for creating transmit and/or receive beams within a fluidic medium. In one aspect, a series of sub-arrays are used to create a larger array capable of forming multiple transmit/receive beams. In one embodiment, a single sided electrode is disclosed, which provides among other things a technological alternative to prior art 2-dimensional array technologies for the purpose of producing multiple beams for applications such as Acoustic Doppler Current Profiling sonars or other 2D array sonar applications. In another embodiment, a dual-sided approach is used which advantageously requires reduced drive voltage(s) for the same output power.
