Jet Control System - Compact

JCS Compact

Jet Control System – Compact (JCS Compact) by KONGSBERG, is a small sized electrical system for operating waterjets steering, reversing bucket and optional interceptor movement, using one or two control stations and including up to two waterjet propulsion units redundant and safely.

The JCS Compact is easy to install and commission due to its compact size, plug-in assembly and the seamless system start-up by shipyard according to provided instructions. For operating small to mid sized single or twin installed Kongsberg Kamewa waterjets.

The JCS Compact provides accurate and reliable operation of the waterjet hydraulic valves using integrated feedback signals. The system together with waterjet propulsors provide smooth operation for steering and reversing, with engine throttle and clutch signals handled by external devices. In single waterjet applications, the system reversing bucket lever can be combined with the external engine signal, in order to reduce the installation area.
