Context
The forces to which the hull unit is exposed depends on its physical size, its location, and the vessel's behaviour in rough
sea. It is very important that the hull unit is sufficiently supported.The forces applied by vibrations and the vessel's movements in the sea can affect the quality of the system performance, the
endurance of the physical installation, and the vessel's safety.
The mechanical support brackets must be designed and manufactured by the installation shipyard to fit the complete installation
in the sonar room. All calculations made to support the design must meet the applicable safety requirements, and apply to the physical properties
of the complete installation.
We recommend that support brackets are placed pointing at minimum three directions with approximately 120 degrees between
them.
NoteThe final design and the installation must be approved by the classification society. Without a proper mechanical support for the hull unit gantry, the guarantee will be void!
It is the installation shipyard's responsibility that the installation trunk and the hull unit gantry are properly secured
against vibrations and sudden movements caused by the vessel's behaviour in the sea.
