Installation summary
Installation of the MF90 system 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. This procedure does not describe any detailed
tasks. Refer to the relevant tasks in this manual.
Note
In order to obtain maximum safety and optimal 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 size, location and design of the sonar room must fulfil all the requirements to the vessel’s
watertight integrity. In the event of a major leak, it must be possible to close all watertight
hatches and/or doors to the room to maintain vessel stability and safety. The physical size of
the sonar room must be limited, so that in the event of a major leak, the flooding of the room
will not induce instability, or cause the vessel to capsize or sink.
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 MF90 system 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.
Procedure
1 Based on the vessel drawings and best practice, determine where the hull unit shall
be located.
