Study Notes
ECDIS Performance Standards and Regulations
- IMO Resolution A.817(19) was adopted on 23rd November 1995 to establish ECDIS Performance Standards.
- SOLAS Regulation V/19 mandates that vessels on international routes must be equipped with ECDIS.
Electronic Navigational Charts
- Vector charts are classified as electronic navigational charts (ENC).
- Intelligent electronic charts are represented by vector charts (S-57).
- IHO S-52 specifies chart content and display requirements for ECDIS.
ECDIS Advantages and Challenges
- ECDIS offers the advantage of enhanced availability of electronic charts compared to paper charts.
- Alarm deafness can result from excessive alarm frequency, potentially leading to dangerous situations.
- Awareness of the limitations of ECDIS is crucial to avoid over-reliance, which can lead to navigation errors.
Electronic Chart Update and Compliance Dates
- All ships are required to be fitted with ECDIS by 1 July 2018, regardless of size.
- The 1998 IMO resolution MSC 86(70) allows the use of ECDIS in Raster Chart Display Systems (RCDS) mode.
Additional Features and Equipment
- ECDIS devices can integrate with various equipment, displaying additional navigational information from vessel machinery.
- All available digital publications, such as Nautical Almanac and Sailing Directions, can be accessed via ECDIS.
- Display types on ECDIS include those that signal isolated dangers within safety contours.
Navigation Techniques and Competencies
- Navigators must balance reliance on ECDIS with traditional navigational aids and situational awareness.
- Statement declaring no need for lookouts is false; lookout duties remain essential for navigation safety.
- Competence in planning and conducting passages using ECDIS is essential for officers-in-charge on vessels over 500 GRT.
Navigational Chart Types and Purposes
- ENC is specifically designed for coastal navigation, enhancing inshore and offshore operations.
- Raster charts are bitmap images derived from scanned paper charts.
- Important file formats for raster charts include BMP, TIF, GIF, and JPG.
General Safety and Operational Awareness
- Proper management of ECDIS is vital; improper use may result in ship groundings or collisions.
- When using ECDIS, awareness and verification of passage plans must be maintained to ensure navigational safety.
