Company Overview

AS SCAN is a Danish high-tech engineering company founded in 1960, specializing in steel structures and hydraulic installations for sectors including Navy, offshore, district heating, and wind industry. The Scan Steering division, acquired in 2004, manufactures advanced steering systems for various vessel types, focusing on innovation, quality, and safety.

Product Range and Specifications

Scan Steering offers steering gear systems with torque capacities from 0.5 to 100 ton/meters, adaptable for single or multiple rudders with mechanical or electronic synchronization. Key components include power packs, cylinders, valve blocks, tillers, fittings, and flexible hoses. All systems comply with IMO, SOLAS, and classification society standards.

Power Packs & Starters

• PSU Single Power Pack: Single pump with squirrel cage motor, IP55 protection, insulation class F, integrated hydraulic tank, optional lock alarm, and classification certificates.
• PSU Double Power Pack: Dual pump unit with two identical motors on a double tank, sharing protection and accessories with the single unit.
• MS1 and MS2 Motorstarters: Single and double motor starters featuring amp meters, emergency stops, and alarms for start/stop, test, power failure, low oil, and overload.

Rudder Control & Starters

• MR100 / MR200: Remote motor starter controls with comprehensive alarm functions.
• RC/MS: Combined rudder control and motor starter with joystick for non-follow-up operation and rudder indication, supporting additional indicators and full-follow-up.
• RC: Double rudder control system with two electrically isolated systems managing up to four hydraulic valve sets, including rudder indicators and control switches.

Universal Repeaters and Accessories

• Digital repeaters (DE-180, DE-200) using NMEA 0183 protocol for rudder angle and turning indicators.
• Bearing repeaters with azimuth capabilities.
• Electronic rudder angle transmitters, panorama rudder indicators, full follow-up wheels, watch alarms, manual pilot and joystick controls, and illuminated rudder indicators.

Customization and Installation

Scan Steering customizes systems to fit unique vessel designs and compact spaces, adapting standard models while maintaining competitive pricing, even for single-ship projects.

Standards and Compliance

All systems are designed and manufactured in compliance with IMO, SOLAS, and classification society requirements, ensuring high safety and quality standards.

Wiring and Electrical Specifications

Wiring diagrams specify the use of shielded, approved cables with minimum cross-sectional areas calculated for 30-meter runs. Power cables must have resistance below 1.0 ohm; signal cables below 2 ohms. Signal cables must be physically separated by at least 15 cm from power cables to prevent electromagnetic interference. Combining multiple cables into one larger cable is prohibited.

Electrical components include motor starters, remote panels, alarm systems, and sensors monitoring oil level, temperature, and filters. Potential-free contacts enable integration with other equipment. Systems support both AC and DC supplies with detailed pin assignments for sensors and controls.

System Integration Examples

• Steering systems powered by main engines.
• Steering gear with dual electrical pumps.
• Complete steering systems featuring mechanical connection bars or electronic synchronization.

Power Supply Specifications

Illumination power supplies range from 0V to +5..+30V DC. Two separate DC supplies (A and B) each provide up to 10 Amps at voltages up to +35V.

Control and Command Interfaces

A port command interface includes an ON state labeled "Auto selected" (not related to Scan-Steering). Potential-free contacts act as start signals for autopilot systems.

Wiring and Junction Terminals

Multiple wiring bundles (W21 to W34, X7 to X9) specify cable sizes such as 4x0.5 mm², 6x0.5 mm², and 2x1.5 mm². Junction terminals are not supplied by Scan-Steering and are installed inside desk consoles or similar enclosures.

Alarm and Monitoring

Alarm panels and related equipment are integrated for system monitoring, including alerts for low oil, overload, power failure, and phase failure.

Key Recommendations and Best Practices

• Use shielded, approved cables with specified minimum dimensions.
• Maintain cable resistance limits to ensure signal integrity and power delivery.
• Physically separate power and signal cables by at least 15 cm to reduce EMI risks.
• Strictly follow wiring diagrams and connection labels for safe, reliable installation.
• Regularly monitor alarms for low oil, overload, power failure, and phase failure to maintain system safety.
• Ensure power supplies meet voltage (0V to +35V DC) and current (up to 10A) specifications.
• Use potential-free contacts correctly for autopilot start signals.
• Verify proper installation of junction terminals inside designated consoles.
• Integrate alarm panels as indicated for comprehensive system safety and monitoring.
