MAN Energy Solutions Alphatronic 3000 - State-of-the-art propulsion control Propulsion Control System Introduction This ‘Product Information‘ publication is intended as a guide during project planning and lay out of the Alphatronic 3000 Propulsion Control Systems. It describes the system in general, the standard control elements and options available for tailoring a propulsion control system to the individual vessel, the propulsion system configuration, the operating modes and the manoeuvring stations. Our product range is constantly under review, being developed and improved according to present...

engines, reduction gearboxes and propellers for an output range up to 60,000 kW. Control is crucial In the process of projecting and estimating propulsion systems, the associated control system is a ‘soft' item frequently handled with less attention. The propulsion control system is often regarded as a necessary auxiliary element that just follows the primary propulsion elements. Fuel consumption, emission levels, performance and propulsion efficiency of the ‘hard' engine and propeller elements are, however, undermined - without the correct matching and performing control system! Inherent Alphatronic...

MAN Energy Solutions Alphatronic 3000 - State-of-the-art propulsion control Alphatronic 3000 system description The system offers three levels of propulsion control: – Normal control with automatic load control – Backup control from bridge and ECR – Independent telegraph system for communication from bridge to machinery space. The system is based on a modular panel design concept to elegantly fit any ship console layout. A configurable touch screen in the propulsion control panel meets a wide range of customer specific functions. The control system fulfils requirements for propulsion plants with...

Normal control The system architecture for normal propulsion control is based on a central PCS unit (mounted in a control cabinet located in the machinery space). The PCS unit is in normal control handling transfer of control responsibility, setup of propulsion power, thrust commands and propulsion overload protection. Communication to the control panels on the bridge and in the ECR is done via a duplicated panel network to the display panels. Other panels on the control location are communicating via a location bus on the display panel. The interface to the propulsion machinery is hardwired...

MAN Energy Solutions Alphatronic 3000 - State-of-the-art propulsion control Application overview Controllable pitch propeller applications Four-stroke medium speed engine applications with a reduction gear comprising no or several clutches can be controlled by the Alphatronic 3000 system in single and twin propeller installations. Further, propulsion lines with a twin-in single-out reduction gear can be controlled by the Alphatronic 3000 system in single and twin propeller installations. The system comprises remote start and stop of the engines from the display panels and control of engine speed...

MAN Energy Solutions Alphatronic 3000 - State-of-the-art propulsion control Main functions of the control panels Manoeuvre Handle Panels (MHP) The Manoeuvre Handle Panel (MHP) is the primary control devise for the main propeller. The panel is always located on the ship’s bridge, normally also in the ECR and optionally on the bridge wings and aft bridge. A control station will comprise one, and only one, Manoeuvre Handle Panel in a suitable version for the actual propulsion plant. The stepper motor(s) of the MHP is built into the spherically shaped handle body - requiring very limited installation...

Propulsion Control Panel - touch screen and display examples The Propulsion Control Panel (PCP) comprises a 7-inch touch screen. The functions and displays are tailor made to the specific engine and propulsion system applications. The main menus shown here are some examples for CP and FP propeller propulsion plants.
