Installation summary
Installation of the MS70 is a demanding task that requires careful preparations, a number of specific procedures, wiring and required system settings.
Context
An overall installation procedure is provided below. The procedure does not describe any detailed tasks, but refers to the relevant procedures in this manual.
Note
In order to obtain maximum safety and MS70 performance, it is very important that the installation procedures in this manual are complied to. You must do the tasks in the order they are described.
The vessel owner must make sure that the installation shipyard holds the applicable competence to perform the installation, and that the applicable maritime authorities are available to verify and certify the installation.
The installation shipyard must provide all necessary design and installation drawings, as well as the relevant work standards and mounting procedures. If required, all documents provided by the shipyard for the physical installation of the MS70 must be approved by the vessel’s national registry and corresponding maritime authority and/or classification society. Such approval must be obtained before the installation can begin. The shipowner and shipyard doing the installation are responsible for obtaining and paying for such approval.
Whenever required, the installation shipyard must also have the transducer installation approved by the applicable maritime authorities.
Procedure
1 Prepare the sonar room to meet the installation requirements.
2 Determine the physical location of the transducer.
Necessary considerations must be taken to avoid acoustic and electric disturbances.
3 Install the transducer.
The transducer will penetrate the hull. For this reason, this is a crucial part of the installation.
4 Install the MS70 system units.
Note that some MS70 system units may be commercial. Unless ordered specifically these are not included in the delivery, and must be purchased locally.
5 Do a dimensional survey to determine the necessary position and angle measurements of the transducer and the relevant sensors.
The MS70 has been designed for target strength measurements of objects in the water column, as well as bathymetric swath mapping. In order to obtain precision data that are both detailed and correct, it is necessary to align the transducer, measure the location and offset of each sensor in relation to the vessel’s coordinate system, and calibrate the complete MS70 prior to use.
Modest accuracy requirements apply when your MS70 system is only used to investigate objects in the water column.
6 Install the cables between the MS70 system units.
Observe the relevant cable plan, procedures, as well as the general requirements for cabling.
7 Install the cables between the MS70 and the relevant peripheral devices.
This is described in the Cable layout and interconnections chapter. Observe the relevant cable plan, procedures, as well as the general requirements for cabling. For more information, refer to the end user documentation provided by the manufacturer.
8 Power up the MS70 for the first time, and set it to work.
Note
In order to power up of the MS70 in a safe and correct manner, the relevant procedures must be complied to!
9 Do a complete MS70 system test.
The tests are described in Setting to work chapter in this manual. They are also provided in the Harbour Acceptance Test and the Sea Acceptance Test documents.
