ETU
NORCONTROL / Kongsberg / Hyundai
New product
An Engine Telegraph Unit (ETU) gives a ship's operating team a clear interface for communicating propulsion orders between the bridge and the engine control locations. SM MARINE SERVICE supplies brand-new marine engine telegraph units and welcomes enquiries for NORCONTROL, Kongsberg and Hyundai variants, including A2 and A3 requirements. This listing is in our Accessories category.
The photographs show lever-type telegraph assemblies with ahead/astern order positions, an emergency-stop pushbutton and an associated indication panel. Different variants can look similar while using different electrical interfaces or internal components. Send the existing unit's nameplate and installation details so we can confirm the correct version before quotation. The two photographs are product references; they do not mean that two units are included in one purchase.

NORCONTROL and Kongsberg names are associated with Norwegian marine control equipment. Kongsberg's historical corporate documentation identifies its Norcontrol businesses in Horten, Norway. Our supply enquiries also cover Hyundai variants, as requested by buyers matching existing shipboard installations. The final manufacturer, type and part number are confirmed against the nameplate of the offered unit.
This is a multi-variant supply listing, rather than a claim that one physical unit was manufactured by three companies. A NORCONTROL marking is visible in the close product photograph. A rear identification plate is not included in the supplied views, so an individual unit's production country or complete type designation is not established here. Manufacturer background should not be confused with a verified “Made in” marking.

The engine telegraph communicates the requested engine order to the relevant operating station. The ahead and astern scales give personnel a readable indication of the command, including positions such as Stop, Dead Slow, Slow, Half and Full. The selected command must be understood within the vessel's control arrangement, whether propulsion is being controlled remotely or orders are being acknowledged at another station.
In a compatible installation, the telegraph interface helps the bridge and machinery-control team coordinate manoeuvring orders. It is important to distinguish an engine-order indication from measured shaft speed: a lever position is an order, while actual engine response is assessed using the vessel's separate feedback and monitoring indications.
Official Kongsberg engine-control literature describes lever-type telegraphs at bridge and engine-control-room stations. That provides functional background for this equipment category; it does not identify the pictured assemblies as a particular newer AutoChief model.
These are observations of the controls and legends in the photographs. They do not establish a completed functional test, a particular supply voltage, communication protocol, class approval or universal compatibility.
Second supplied assembly view: compare lever arrangement, panel legends, mounting plate and cable connections when requesting a replacement.
SM MARINE SERVICE accepts enquiries for A2 and A3 versions as well as other required engine telegraph variants. Provide the full designation rather than only the A2 or A3 suffix. A short suffix may not uniquely identify the complete assembly, its electronics or its software configuration. The photographed units are not assigned an exact A2/A3 designation without their rear plates.
Likewise, a Hyundai, Kongsberg or NORCONTROL unit should not be treated as interchangeable simply because the handle and front panel look alike. Connector arrangement, signal interface, mounting dimensions, station role and installed control-system version all matter when matching a replacement.
If a complete engine telegraph is not required, contact us about the specific component needed: a telegraph PCB, indication panel, lever assembly or another identified spare. Send clear internal board photographs and exact board markings, together with the complete unit nameplate. We will confirm the available supply scope for the requested item.
The visible HA304972C marking is retained here for panel identification. It is not presented as a verified internal circuit-board number. PCB supply or a replacement assembly must be checked against the actual component; no repair service, board interchangeability or component stock is assumed from these photographs.
A matched quotation is more useful than choosing solely by appearance. Confirm the offered unit's identity, included cables and accessories, available documents and delivery terms before ordering. Installation and commissioning should follow the vessel's applicable technical documentation and be carried out by qualified personnel.
We accept international marine spare-parts enquiries from ship managers, purchasing teams, repair workshops and vessel operators. Send your required engine telegraph details to our Chattogram team for price and availability. The quotation will confirm the actual product variant and shipping arrangements for the requested destination.
Is this listing for a brand-new product?
Yes. The selected listing condition is New product. The quotation identifies the exact unit and supply scope being offered.
Can you supply NORCONTROL, Kongsberg and Hyundai variants?
We welcome enquiries for all three, including A2/A3 requirements. Please provide the full nameplate details so that availability and the correct version can be confirmed.
Does an A2 unit automatically replace an A3 unit?
No automatic interchangeability is claimed. Match the exact hardware, interfaces and system requirements.
Can I enquire about a PCB only?
Yes. Send the board's own markings and photographs; the panel marking alone does not identify an internal PCB.
