1. Introduction
The SeaKing Sidescan family of sonars provide various methods for obtaining survey
sonar data. The two Towfish and SK150 are both designed to be towed behind a
vessel as it navigates survey lines, while the ROV mounted device is designed to be
fitted to a remotely operated vehicle which is then used to perform the survey.
Electrically and acoustically the devices are very similar, the ROV model is
merely shipped without a hydrodynamic tube and in three components (left/right
transducer and electronics pod). The SK150 is a specially designed Towfish that
can withstand higher pressures found in deeper water. Communication between the
surface computer and the devices can be via RS232, RS485 or ARCNET protocols.
The ROV mounted device can be combined with the Tritech International Ltd Subsea
Junction Box which will allow other devices, such as the SeaKing or Hammerhead
Sonar to be used on the same vehicle.
All three devices are controlled using the Tritech International Ltd Seanet Pro control
and display program and are capable of exporting to a variety of industry standard
formats for use in post-processing survey packages. It is also possible to use the data
in the Tritech International Ltd Sonar Image Tiler program in order to build up a
complete picture of a survey site.
