Global Query Fan-Out / FAQ
Q1: What is the difference between ENC (vector charts) and RNC (raster charts), and which are required for ECDIS?
A: ENC (Electronic Navigational Charts) are vector charts where chart objects are stored as digital data that can be manipulated, queried, and displayed at different scales. RNC (Raster Navigational Charts) are scanned paper charts displayed as images without object-level data. SOLAS requires ECDIS to use ENC (vector charts) as the primary chart format. RNC can be used in RCDS (Raster Chart Display System) mode or as backup, but ENC is required for full ECDIS functionality. We provide both ENC and RNC services, with emphasis on ENC compliance for ECDIS operations.
Q2: How often do ENCs need updating, and what happens if updates are missed?
A: ENCs should be updated weekly per IHO recommendations and Flag State requirements. Missed updates can result in expired charts, potentially creating navigation safety hazards and regulatory non-compliance. ECDIS systems provide alerts for expired charts. If updates are missed, immediate action is required to update charts before voyage departure. We provide automated update scheduling, monitoring services, and emergency update assistance to ensure chart currency and regulatory compliance.
Q3: What are the requirements for dual ECDIS configuration and backup chart arrangements?
A: Dual ECDIS configuration requires two independent type-approved ECDIS systems with independent power supplies, sensor inputs, and chart data. Backup chart arrangements require either paper charts or RCDS (Raster Chart Display System) covering the vessel's trading areas. Both systems must have current charts and be operational. The backup arrangement must be maintained and ready for immediate use if primary ECDIS fails. We provide dual system verification, backup chart management, and failover testing to ensure compliance with SOLAS and Flag State requirements.
Q4: How does ECDIS service integrate with other bridge navigation systems?
A: ECDIS service includes verification of integration with other bridge systems: GPS/GNSS for position input, gyro compass for heading, speed log for speed input, AIS for target overlay, radar for radar overlay (ARPA), and conning displays. Technicians test NMEA 0183/IEC 61162-1 interfaces, verify data accuracy, test sensor redundancy, and ensure proper integration per IMO performance standards. We also test alarm integration between ECDIS and other bridge systems for comprehensive safety.
Q5: What is the procedure for ENC permit acquisition and IHO S-63 compliance?
A: ENC permit acquisition involves: (1) Selecting chart catalog (AVCS, Primar, regional), (2) Applying for permits through authorized agents, (3) Installing permit keys in ECDIS via IHO S-63 data protection scheme, (4) Verifying permit validity and coverage, (5) Setting up automatic permit renewal. IHO S-63 ensures data protection and prevents unauthorized use of ENCs. We provide complete permit management services including acquisition, installation, renewal, and troubleshooting.
Q6: Can ECDIS service be performed during voyage, and how are chart updates handled remotely?
A: ECDIS service can be performed during voyage via remote support using satellite communication. Chart updates can be downloaded and installed remotely, system diagnostics can be performed, and troubleshooting assistance can be provided. However, physical hardware repairs, complete system overhauls, and some software updates may require port attendance. We provide 24/7 remote ECDIS support, satellite-based update delivery, and remote diagnostics to minimize voyage disruptions while ensuring chart currency and system functionality.
