Saving considerably on building costs & mounting space. It comes with a back-up cable of 20m length that can be simply plugged in on transmitter- and receiver sides, as alternative forthe wireless transmission . The system is suitable for:
  • Propulsion control: Engine RPM, Propeller pitch.
  • Steering control: Rudders, Azimuthal thrusters.
  • Thruster control: Tunnel thruster RPM, retractable.
  • Joystick operation.

CAESAR Systems for High Speed Crafts

The CAESAR Propulsion Control Systems (CAESAR PCS) are designed for the control of propulsion, steering and motion damping devices onboard of High Speed Crafts (HSC). The system has a modular design with emphasis on weight-saving. This allows for its application on various types of HSC, such as (wave-piercing) catamarans, fast supply vessels, trimarans, naval vessels and highspeed yachts. It enables integrated remote control of all onboard waterjets, rudders and motion damping devices. The CAESAR PCS interfaces with available machinery sensors and actuators to control waterjet buckets, steering nozzles (via proportional valves) and auxiliary controls operating hydraulic pump(s), clutch and thrustbearing. High-Speed-Craft systems consist of multiple control cabinets, each with individual controllers for independent operation. Cabinets contain two digital controllers (main and back-up) where the controller can operate up to two waterjets. Main controllers operate follow-up steering control and power/reversing control. Whereas the backup controller operates jog-switch back-up control and indication of the steering nozzle, bucket and impeller speed. The CAESAR PCS is developed and designed in accordance with the IMO High-Speed Craft Code 2000. Modularity and use of generic hardware allows independence of availability of Commercial-Off-The- Shelf (COTS) hardware. Each system is assembled at the Kwant Controls’ facility and supplied with customer’s choice classification. After integration, it is subject to a thorough Factory Acceptance Test (FAT), in attendance of the Classification surveyor, owner and/or yard representative(s). Please see downloads for the CAESAR High Speed Craft Systems brochure.

Electric shaft system

The Kwant Controls levers are primarily used for electronic Remote Control of marine propulsion plants, which typically consist of a combination of engine / propeller / gearbox / clutch sub-assemblies. Remote Control is done from bridge level (WH Fwd, WH Aft, Port side wing or Stbd side wing). To achieve this, the levers are equipped with signal transmitters for engine RPM, clutch direction etc. that are wired to the propulsion plant control system. Telegraph Systems In case the Remote Control (RC) system is out of order, a switch over to telegraph mode can be made. The same levers are now used to send telegraph commands from the wheelhouse to the engine control room (ECR) or engine room (ER), whichever is selected as the current reply position. An alarm will sound until the command has been acknowledged. The propulsion plant is now remotely controlled from the ECR- or ER levers, or manually in case the ER lever has no remote control transmitters. Electrical Shaft Systems The purpose of an electrical shaft system is to synchronize the operating levers of all control units connected, mostly on the main bridge and bridge wings. It enhances the ease of use and increases safety in emergency situations, since control can be taken directly from any of the operating positions connected. Synchronization enables switching of operating position without changing the control signals for propulsion and/or heading (bump-less take-over). A second advantage is that the transmitters providing these signals are required on just one of the control units, since all levers will move simultaneously. To achieve synchronization, the control units are equipped with servomotors. Electronic circuitry will take care of driving these motors, as well as handling the take-over requests. Take-over can be achieved by means of illuminated pushbuttons, or by potential free contacts from other systems.

Steering Wheel

The Kwant Controls steering wheel is in fact a special type of the PMA potentiometer drive, dedicated to adjusting the ship’s heading. The material of the wheel is usually transparently varnished wood, a finish in black paint is optionally available. The diameter of the hand wheel is 250mm, the base plate comes in 3 variants: 144x144, 192x192 or 270x270mm.

RSA-series, Rudder angle

Indicators of the RSA-series have been especially designed for rudder angle indication. Types RSA-3 thru RSA-7 are based on the same servomotor principle (RSM-4) and require only an external potentiometer as well as a 24VDC supply voltage to make them operational. The RSA-9 and RSA-10 are cost reduced versions of the RSA-7 and RSA-4 respectively. Kwant Controls also supplies a matching signal transmitter mounted in a rugged housing, the RSG.-1 which can be linked to the rudder machine by means of a sprocket and chain connection. A combination of the RSG-1 and one (or more) of the RSA indicators together form a reliable rudder angle indication system that will last for many years without any maintenance. Diagrams have been added to show some of the possible system set-up’s. In case a panel indicator with a 4-20mA signal input is required, an indicator of the ISI family should be used. These indicators offer galvanic isolation of the input signal and power supply. Please refer to the ISI datasheet for further information.

ASA-series, 360°

Indicators of the ASA-series have been designed for 360° endless thruster azimuth angle indication. They are based on the servomotor principle and require only an external potentiometer as well as a 24VDC supply voltage to make them operational. The essential difference when compared to standard indicators, is that the ASA’s pointer(s) can rotate endlessly without an end stop. To achieve this, a twin wiper potentiometer must be used as angle transmitter.

RSCU-H

The RSCU-H series consist of three members in the following executions:
  • RSCU-H96 (96x96mm);
  • RSCU-H144 (144x144mm);
As their names already suggest, the main difference is the size of the top plates. The RSCU-H96 bottom section has been designed as a machined aluminium block. The RSCU-H144 is composed more traditionally and therefore allows more variations when it comes to machinery interfaces. They both share the recognizable cylinder shaped control head, identical to that of the BUK-H propulsion levers.

CAESAR Systems for Dredgers

The electronics revolution over the last decades has a serious impact which is not limited to:
  • Obsoleteness of analogue electrical components such as dedicated circuit boards.
  • Lack of skilled engineers to service older systems. Therefore keeping spare parts onboard does not guarantee uninterrupted ship’s service.
  • Growing complexity and diversification of digital systems further limiting the possibility to find skilled engineers.
The above is becoming a serious but often ignored risk for ship operators, since a major malfunction in the control system can create idle time of the vessel. The good news is that a retrofit with a CAESAR Propulsion Control System (CAESAR PCS) can eliminate this risk. Furthermore, it will result in lower maintenance costs as well as improvements such as reduced fuel consumption. Over the years the proven CAESAR PCS has grown towards an extensive installed base for the world’s leading maritime companies, including the leading dredging corporates. CAEASAR systems are dedicated for control of propulsion and steering. All systems are built; to fulfill customer requirements and according to the rules & regulations of the Classification Societies. Its modular configuration allows for its versatile application on various types of ships. Furthermore, the CAESAR PCS is developed on a generic platform allowing to become independent of availability of Commercial-Off-The-Shelf (COTS) hardware. For Trailing Suction Hopper Dredgers (TSHD), dedicated (software) modules are designed, which makes the CAESAR PCS well suitable for various configurations and control principles. Both for main machinery driving dredge pumps and controllable pitch propellers (CPP’s) onboard of the TSHD. Please see downloads for the CAESAR Trailing Suction Hopper Dredger Systems brochure.
