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 SY50 system, the physical location of the installation trunk must be carefully selected.
The installation trunk - with a blind flange - can be ordered from Kongsberg Discovery 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.
NoteIf the installation trunk is manufactured locally, the installation shipyard is responsible for obtaining the approval certificates
from the relevant national registry.
