Kongsberg Maritime has shipped its 3,000th AuthChief C20 control system

Kongsberg Maritime says that it has achieved 3,000 deliveries for its AutoChief C20 machinery control system, following the latest factory acceptance test (FAT).

The AutoChief C20 is designed for low to medium speed diesel engines with fixed or controllable pitch propellers. The latest FAT took place on 8 March 2011 at Kongsberg Maritime Korea's facility in Busan, in the presence of representatives from Hyundai Heavy Industries (HHI) and Lloyd's Register. Following the successful FAT, the system will be delivered to HHI’s EMD engine division, for use on a large two-stroke engine aboard a new building for ship owner Seaspan. HHI was the first customer to shop test the AutoChief C20 system, on a MAN B&W 6S70ME engine for a Sovcomflot vessel in November 2004.


AutoChief C20 is the fifth generation of Kongsberg Maritime's propulsion control system which was originally launched in 1967. Since then, the system has undergone several major redevelopments in order to support the advances made by engine manufacturers and automation technology. Kongsberg outlines the development and operational experience, and the introduction of features, as follows:
