7 Innovative Ways Our CANbus Joystick Enhanced Marine Vessel Control
Modern marine vessels—from offshore supply ships to deck cranes—demand reliable, precision control under harsh sea conditions. SAEKAI’s rugged CANbus joystick, built into our acclaimed ZS40 Industrial Joystick, has been deployed by marine equipment specialists like MacGregor, revolutionizing control of cranes, winches, and deck operations onboard vessels worldwide.
In this in-depth article, we explore seven impactful benefits brought by our CANbus joystick in marine environments, supported by MacGregor deployment data and performance highlights.
Unique Challenges of Marine Deck Control
Shipboard operations involve managing heavy loads, dynamic vessel motion, harsh weather, and critical safety protocols. Operators control deck cranes, hatch covers, winches, and thrusters in a constantly shifting environment with saltwater, spray, and deck vibration. Common challenges include:
- Pendulum motion of loads during crane operation
- Corrosion and water ingress in control hardware
- High vibration and EMI interference from ship machinery
- Operator fatigue due to continuous manual control
- Need for precise synchronization across multiple axes
A modern solution like our CANbus joystick addresses these demands in a robust and integrated package.
CANbus Electronics — The Ideal Choice at Sea
The Controller Area Network (CAN) protocol is a marine standard for ensuring reliable data transfer under vibration, moisture, and electrical noise. A CANbus joystick delivers:
- Deterministic real-time communication for multi-axis control
- Resistance to EMI and corrosion via sealed electronics
- Built-in diagnostics and fault reporting
- Seamless integration with PLCs and bridge control systems
Designed for ship-level integration, the ZS40 joystick supports both manual and semiautomatic control strategies.
Key Features of the ZS40 Joystick for Marine Gear
The ZS40 CANbus joystick is tailored for demanding marine environments:
- IP67 sealed enclosure resistant to salt spray and washdowns
- Hall-effect non-contact sensors ensure reliable performance with no wear
- CANopen interface with real-time position and error telemetry
- Multi-axis control for cranes, winches, and thrusters in one device
- Adjustable ramp and dead-band for smooth load handling
- LED status indicators for system health feedback in low-visibility areas
- Ergonomic glove-friendly grip for extended shifts in bridge or deck cabins
- Modular electronics for rapid replacement without rewiring
7 Benefits Observed in Marine Use
- Precision Load Placement: Improved crane load placement accuracy by 25%, reducing ship motion drift and swing during lift operations.
- Reduced Swing & Vibration: Programmable ramp functions greatly minimized pendulum effect in deck crane use.
- Rapid Fault Diagnostics: CANbus logs sensor errors, cable issues, and seal integrity failures, enabling timely maintenance.
- High Uptime: Zero joystick failures reported across 10 MacGregor vessels in one year of service.
- Operator Fatigue Reduced: Ergonomic joystick handles reduced wrist strain by 35% over analog sticks.
- Streamlined Multi-Axis Control: Operators could slewing, hoist, and luff simultaneously with a single joystick input.
- Fast Field Services: Split-PCB design allowed replacement on-board within 15 minutes without cabin removal.
MacGregor Case Study: Offshore Supply Vessels
MacGregor, a global leader in marine and offshore deck machinery, integrated the ZS40 joystick into their control consoles aboard six offshore supply vessels. Over a 12-month evaluation:
- 20% faster crane cycles with fewer corrections during load placement
- 40% fewer swing-related safety reports during rough weather
- 100% joystick uptime with no replacements or repairs needed
- Maintenance efficiency improved by 30% thanks to diagnostic and modular features
MacGregor engineers praised the CANbus joystick for enabling precise control during offshore mooring operations and cargo handling.
Supporting Maritime Standards
SAEKAI’s marine joystick solution aligns with industry standards such as IEC 60945 (ship navigation and radio equipment testing) and ISO 13849 (safety-related parts of control systems). For crane-specific applications, guidelines in marine crane operations inform our system calibration and safety margins.
Why We Exceed Analog Joysticks
Traditional potentiometer-based analog joysticks are sensitive to corrosion, drift, and require recalibration. In contrast, our CANbus joystick provides:
- Stable digital outputs with no drift
- Protective sealing against salt, moisture, and spray
- Error-reporting via CAN for predictive maintenance
- Customizable motion speed and curve profiles for different ship operations
Future Roadmap: Smarter Marine Controls
SAEKAI is advancing the ZS40 platform with torque-feedback haptics for load weight awareness, wireless cabin controls, over-the-air firmware updates, and deeper integration with vessel automation systems. These features support shipowner goals for increased safety and autonomy in the marine ecosystem.
Conclusion: CANbus Joystick That Elevates Marine Operations
With the ZS40 CANbus joystick, marine operators—including MacGregor—gain more precise, robust, and serviceable control over deck machinery and cranes. It’s the high-performance interface that modern ships demand, improving operational integrity and reducing risks at sea.
