The Kongsberg ETU (HA334941B1) is an engine telegraph unit forming part of the vessel’s marine control system, where engine telegraph equipment carries engine orders between the bridge and the machinery spaces. It is marked with the code SW56002-A3 and a second identifier, HS443812B, alongside the main part number. As one element of the propulsion order chain, the unit sits within the wider bridge and engine control installation rather than working on its own. It is supplied in used condition.
