Remember, you have an option to use DR position (deselection of GPS sensor). When the display scale on an ECDIS is set to a scale smaller than an object's SCAMIN value, the object will disappear, thus reducing clutter and improving ENC rendering speeds. 2. Sir, I think it is the funciton of safety contour , instead of your mentioned safety depty. The main idea should be to primarily see the light blue shade of the safety contour on the ENC. 1. As a result, route planning and monitoring alarms may not always be activated when approaching such dangers and may result in groundings. Welcome to your Annual ECDIS Competency Assurance Training, or ECDIS ACAT as it is better known. Dangers that are shoaler are portrayed with the unique ECDIS “isolated danger” symbol shown at left. So, it is as though, DR is selected. Quelle: IHO Publication S-52 Appendix 2: Addendum to annex A, part I, users´ manual. The contour settings on the ECDIS provide colour to the ENC and also give the ECDIS its anti-grouding ability. Lack of ECDIS system familiarity and lack of knowledge of ENC symbols, Failure to interrogate chart cautions and symbols, such as isolated danger marks or cautionary areas, ENC data and other available information not properly analysed (including sector light zones, sailing directions, mariner’s handbook and other relevant sources), Latest updates not applied to ENC database, Under Keel Clearance (UKC) calculations do not consider Category Zone of Confidence (CATZOC), squat or height of tide, Controlling depth (safe water) not accurately defined, Minimum clearing distance from hazards not clearly defined (vertical – UKC and horizontal – distance off), Chart and World Geodetic System (WGS) 84 datum discrepancies, Features with area boundaries (such as reefs) are incorrectly programmed as point features, Up-to-date port/berth information not shown on latest ENC, Route plotted very close to or over navigational hazards, Knowledge gaps and inability to distinguish between alarms, cautions and indicators, Varying standards of ECDIS generic training, type-specific training and familiarisation, Reducing safety margins (such as UKC or distance off), Berth-to-berth passage plan not available, Incorrect application of safety depth and safety contour, No-go areas and manual contours not defined as per calculated safe water depths or not made alarmable, Safety parameters and alarm limits not set, Cross-track Corridor (XTC) wider than available width of navigable waters, Environmental factors (such as tidal streams) not considered in wheel-over calculation, Software limitations for setting features such as wheel-over positions, manual no-go areas, manual layer and other information, Course information not readily apparent over various legs, Programmed safety contour layers not available at required safe water depth, Lack of familiarity with route validation feature, Visual checks not undertaken for each leg of the passage, Automatic route validation feature not used, Route validation (visual, manual and automatic) not undertaken by the Master as well as the Navigating Officer, Route validated checks undertaken on a smaller-scale ENC, After passage plan amendment, route not re-validated by Navigator and re-approved by Master, Excessive number of alerts generated during system route check function, Route validation feature is too complex to use, Acknowledging alerts without investigation (such as exiting XTC, anti-grounding alarm or critical points), Lack of user knowledge and system familiarity; for example, in the case of pilots and new on-signers, Display settings not optimised for day, dusk, night light conditions, Lack of familiarity with contingency plans and procedures, Planned safety settings changed or not set before execution of passage, or subsequently, Compilation scale not being used (navigation on over-scale or under-scale ENCs), Minimum layers for safe navigation not being displayed, Position verification/plotting not being undertaken using combination of line of positions, radar overlays and/or parallel indexing, as and where available, Look-ahead settings inappropriate or changed randomly, Position not being monitored during pilotage, Use of Automatic Identification System (AIS) on ECDIS as primary means of collision avoidance, Lack of ECDIS-related contingency plans and procedures, Course information not readily visually apparent over various legs, Visual perception of ECDIS data when set to day, dusk or night preset modes, Ensure that installed systems can support the latest industry specifications and requirements, Implement procedures (within SMS or as a stand-alone plan) in order to provide guidance for the use of ECDIS systems and the, integration of them within Bridge Operating Procedures. ECDIS Navigation Procedures and Practices: ECDIS Hardware, Software and ENC Data: Appraisal: Lack of ECDIS system familiarity and lack of knowledge of ENC symbols; Failure to interrogate chart cautions and symbols, such as isolated danger marks or cautionary areas; Overreliance on ECDIS; Largest scale ENC not uploaded The chart scale in use – the significance of ‘compilation scale’. isolated danger marks or cautionary areas 3. It has several advantages over paper charts as listed below; Continuous route monitoring Continuous Since the introduction of ECDIS, we have seen ship operators have divided approximately equally into two camps: there are those have reduced the required frequency of manual (terrestrial) ECDIS position plots to once an hour or even once a watch on the coast; this is combined with continuous track monitoring by parallel index and frequent position verification by the use of radar overlay. Dangers that are shoaler are portrayed with the unique ECDIS “isolated danger” symbol shown at left.

However experienced mariners, at the end of planning stage reviewed the developed plan, and presented it to bridge team. The Safety contour setting was primarily designed to clearly distinguish between the safe and unsafe waters on the ECDIS, Safety contour= Dynamic draft + Company UKC policy – Height of tide whereas Dynamic draft = Static draft + Squat+environmental allowances. Deep contour indicates the limit of sea area where shallow water effects occur that can affect a vessel. Mariners should never go over bold depths! Isolated dangers are automatically shown above safety contour i.e. 5mins Less alarms due to re-arranging categories and objects in Dangers that are shoaler are portrayed with the unique ECDIS “isolated danger” symbol shown at left. General ECDIS allows for monitoring of a ship’s position in real-time throughout the voyage and integrates information from GPS, Gyro, Radar, ARPA, AIS and other navigational equipments into a single display. The chart display, and sometimes symbology, changes depending on how you set ECDIS up. ECDIS alarm parameters. OCIMF analyzed navigational incidents (11 published reports and seven company investigation reports) between 2016 and 2018, involving tankers fitted with ECDIS. The need for effective ECDIS display management. This means that if a depth along the track is bold, the mariner should ask himself, is it safe to pass? Question yourself -Can poor safety settings cause a vessel to run Aground?? Continuous route monitoring 2. Will allow the mariner the ability to plan and check routes, viewing the conditions they will encounter on a given date or time period in the future. So, it is as though, DR is selected. Terms & Conditions Policy Update version 4.1 for 2019. Unclear ECDIS carriage policy 2. The navigational alarms include hazards such as shallow depths, shoals, and isolated dangers as well as minimum under-keel clearance, like an anti-grounding alarm, provided that the … SQEMARINE can provide guidance on amending existing manuals or providing updated new ECDIS Management manual as required by client. Contrastingly, cardinal buoys will indicate a direction away. An Isolated Danger Mark, as defined by the International Association of Lighthouse Authorities, is a sea mark used in maritime pilotage to indicate a hazard to shipping such as a partially submerged rock. However, they can also be seen below safety contours provided you select feature ''Isolated dangers in shallow water'' in few ECDIS. The vessels position can be continuously monitored on screen. Isolated danger mark. ECDIS can be used as an Anti-Grounding Tool ; ECDIS can be used as a very effective Anti-Grounding tool when properly set up and used along with appropriate sensors. It is recognisable by its black and red bands and top-mark of two black balls. In the previous version, isolated dangers of depths lesser than the user-defined safety depths would show in-depth areas greater than the safety contour. Isolated Danger marks. An important example is that ECDIS displays wrecks, rocks and other obstructions with their traditional “paper chart” symbols if they are at or deeper than the depth of the safety contour set for the ship. Defining the form and type of presentation Form of the symbols: In the VISIBILITY SETTINGS dialog (at the RADAR-PILOT: in the CHART menu) using the SYMBOLS field. A recent software update on the ECDIS has revealed a change in the way isolated dangers are indicated. Welcome to your Annual ECDIS Competency Assurance Training, or ECDIS ACAT as it is better known.

Overreliance on ECDIS 4. • buoys, beacons, lights, notice marks • waterway axis with kilometres and hectometres. The navigators must remember that the display of underwater obstructions or isolated danger symbols can change according to the settings of this safety contour which also marks the division between navigable (safe) and non navigable (unsafe) water. ECDIS may not display some isolated shoal depths when operating in ‘base’ or ‘standard display’ mode. So acknowledge ECDIS alarms carefully , Being in grey, means that your vessel will be experiencing shallow water effects. These buoys are rarely used in sandy regions, such as The Netherlands or Germany. Readily available … By now, you should be able to create lines, shapes and add text in the user map. The course is specific to the ECDIS they have out of the 42 current manufacturers of ECDIS. A few uses of virtual ATONs include environments where buoys are moved seasonally, such as in sea ice, or where a marker needs to be placed quickly, such as to mark a newly identified isolated danger or wreck. However, the most obvious and potent danger of the above is the … The ECDIS – Guidance for Good Practice is important also to other ECDIS users besides of Navigators, like VTS and SAR operators/operation Centres, offshore installations etc. Virtual AIS ATON – An aid to navigation with no physical structure.
