Installation trunk requirement
An installation trunk is required for hull unit installation. The installation trunk is not
included in the standard delivery.
The installation trunk provides the physical foundation for the entire hull unit. The
installation trunk penetrates the hull. The installation trunk is therefore a crucial part of the
hull unit assembly. In order to ensure proper operation of the MF90 system, the physical
location of the installation trunk must be carefully selected.
The installation trunk - with a blind flange - can be ordered from Kongsberg Maritime as
an optional delivery. As an alternative, the installation trunk can be manufactured by the
shipyard based on the drawings in this manual. A locally manufactured installation trunk
can be adjusted to better fit the properties of the vessel’s hull.
Note
If the installation trunk is manufactured locally, the installation shipyard is responsible for
obtaining the approval certificates from the relevant national registry.
The installation trunk is not used when a gate valve is mounted. The installation trunk is
then replaced with a transducer dock.
