4.1 System Installation
Installation of the swath mapping system on the MES vessel SURVEY 1 occurred on March
14, 2019. The AI Universal Sonar Mount (USM) Expedition mount was attached to the
starboard side of the SURVEY1. A permanent mounting plate is affixed to the gunnel of the
SURVEY1 and the USM hinge mount bolts on to the plate. A vertical Z-Pole is attached to the
hinge mount, and the ET6205 transducer attaches to it.
An antenna mast with GNSS spreader bar attaches to the back side of the hinge mount, and
a plate for the POS MV IMU attaches to the front side. Thus all MPES components are affixed
relative to the mount and not the vessel.
Figure 8: ET6205 mounted on starboard side of SURVEY1.
The Z-Pole pivots around the USM X-Pole and hence be raised out of the water during vessel
transits. Deployment of the transducer into a vertical / survey configuration was done in a very
controlled manner through a combination of purpose-built large wrench attached to the
rotation mechanism on the hinge mount and a rope attached near the base of the pole.
Recovery of the pole into a horizontal position was done in a similar manner.
