Prerequisites
For accurate location of the transducer, you need the detailed vessel drawings. You also need the installation angles that were recorded when the transducer was installed. For maximum accuracy, we strongly recommend that you use the information provided by a dimensional survey.
NoteDetermining the relative positions and orientations of the sensors and the transducer with high accuracy is important. This requires professional land surveying done by qualified and trained surveyors using proven survey equipment and methods
. We recommend that you use third party consultants with well proven experience with vessel dimensional control. The information provided by the dimensional survey is entered into the MS70 software as installation parameters.
Neither tools nor instruments are required. The MS70 is switched on and working in normal operational mode.
Context
The physical location and the installation angles of the MS70 transducer are critical for the MS70 data accuracy.
Use the centre of the transducer face as reference, and define the offset values related to the Ship Origo. The installation angles relevant for the transducer must also be defined. These values were recorded during the transducer
installation, and they define the direction of the transducer face.
NoteThe required accuracy of the offset and rotation angles depends on the accuracy requirement for the MS70 data. It is very important that the transducer installation angles are measured and recorded accurately during the installation,
and that they are defined accurately in the software. Incorrect angles will greatly reduce the data accuracy.
