Installation trunk description
The installation trunk provides the physical foundation for the entire hull unit. The installation trunk penetrates the hull. It is therefore a crucial part of the hull unit assembly. In order to ensure proper CS90 operation, the physical location of the installation trunk must be carefully selected.
Note
The installation trunk is not included in the standard delivery.
The installation trunk is not used when a gate valve is mounted. The installation trunk is replaced with a transducer dock.
The installation trunk may be fabricated by the shipyard, or supplied by Kongsberg Maritime as an option. The drawings of the installation trunk and the blind flange are included in this manual.
Due to the different flange diameters, different installation trunks are used.

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.
