SYSTEMLegal aspects and requirements (IMO MC 1.27 C1)What is a ECDIS?ECDIS is an abbreviation for Electronic Chart Display And information system. It is a full system that consist of many arts and is controlled under a strict performance standard. As the name states it is not only a chart system but also a information and a common interface system of a variation of sensors known in Navigations. Creating a very powerful Navigation tool.

Legal aspects and requirements (IMO MC 1.27 C1)ECDIS things you should knowECDIS is just another piece of hardware we have to buy and mount it on the bridge to comply with the regulations.

Legal aspects and requirements (IMO MC 1.27 C1)ECDIS things you should knowWhat does it take to operate this thing as my primary means of navigation?

Legal aspects and requirements (IMO MC 1.27 C1)Background and Legal history of ECDISIn 1995 the first IMO Resolution allowed ECDIS to be used as conventional ships bridge equipment. In 1999 Transas Marine became the first company in the world to receive type approval for its Navi-Sailor 2400 ECDIS.In July 2002 SOLAS Chapter 5 was amended and for the first time included a provision for the use of an electronic means of navigation to meet SOLAS chart carriage requirements. Such provision is included specifically in SOLAS V Regulation 19.2.1.4. Details of ECDIS (Electronic Chart Display and Information System) and its use are contained in the IMO ECDIS Performance Standard A817(19); this specifies equipment capability and addresses issues such as back-up and use of charts. In June 2009 Amendments to SOLAS regulation V/19, to mandate the carriage of Electronic Chart Display and Information Systems (ECDIS) were adopted.Legal aspects and requirements (IMO MC 1.27 C1)- READ PPT-

SOLAS Chapter V, Safety of NavigationRegulation 19: Carriage requirement for ship borne navigation systems and Equipment19.2.1.4: All ships irrespective of size shall have nautical charts and nautical publications to plan and displays the ships route for the intended voyage and to plot and monitor positions throughout the voyage. An electronic charts display and information system (ECDIS) is also accepted as meeting the chart carriage requirement of this subparagraph;19.2.1.5: All ships irrespective of size shall have back-up arrangements to meet the functional requirements of the above subparagraph .4, if this function is partly or fully fulfilled by electronic means.**An appropriate folio of paper nautical charts may be used as an back-up arrangements for ECDIS. Other back-up arrangements for ECDIS might be acceptable (see appendix 6 resolution A.817(19)), as amended and local administration acceptance.

Legal aspects and requirements (IMO MC 1.27 C1)SOLAS Chapter V/19:Rule 19.2.1.4 describes not only the use and general functions of charts and nautical publications, it also sets ECDIS on the same level by stating that it may be accepted as meeting the chart carriage requirements As you can see it is still the same rules that applies for chart carriage, it is just the matter how we comply that has changed.- READ PPT-

SOLAS Chapter V, Safety of NavigationRegulation 27: Carriage requirement for shipborne navigation systems and Equipment

Nautical charts and nautical publications, such as sailing directions, lists of lights, notices to mariners, tide tables and all other nautical publications necessary for the intended voyage, shall be adequate and up-to-date.

Legal aspects and requirements (IMO MC 1.27 C1)Since the transition toward electronic products on board of sea going vessels is in full swing, tide tables, lists of lights and other nautical publications have to be updated as well as the electronic chart folio. The term up to date means, that you have to use the latest available version. For electronic charts this means using the latest edition and applying a weekly update to the charts in use. In addition to the regular update, the mariner has to prove that the Notices to Mariners from the present and the last two years are on board (by national Maritime legislation). T and P will be included within the regular update. In order to prove the appropriate implementation of T and P - Notes, the Add Info - User Chart can be used to manually enter and store the Notes.

SOLAS Chapter V/27:This regulation covers the requirements of updates of charts and publications.- READ PPT-

IMO ECDIS Performance Standard A817(19)Electronic Chart Display and Information System (ECDIS) means a navigation information system which, with adequate back up arrangements, can be accepted as complying with the up-to-date chart required by regulation V/19 & V/27 of the 1974 SOLAS Convention

Legal aspects and requirements (IMO MC 1.27 C1)If we look on the statement in the ECDIS performance standard it states that and ECDIS can meet the earlier mentioned requiremnets.

What is the difference between ECS and ECDISECS (Electronic Navigation System)Electronic chart software Unofficial charts (e.g. Transas TX-97)None approved hardwareECDIS (Electronic Chart Display and Information System)Type-approved hardwareType-approved ECDIS softwareApproved installationOfficial charts (ENC/SENC/ARCS)Chart corrections subscriptionThe crew has been trained for the usageCAN BE USED AS AN AID TO NAVIGATIONCAN BE USED FOR PRIMARY NAVIGATIONLegal aspects and requirements (IMO MC 1.27 C1)So what is the difference between a normal simple chart system running on a Normal PC or hand held GPS and a ECDIS?

ECS: This system can ONLY be used as AID to Navigation and main navigation needs to be conducted on paper charts.

An ECDIS consist of a list of components, all of them needs to comply with the performance standard individually and together. In addition the system needs to be loaded with official chat data which a correction subscription, the installation have to be conducted by a certified engineer and the user have to be trained for the usage and can in the usage.If all points are fulfilled the system can be used as a primary Navigation tool. In order to fully comply with the chart carriage requirements a secondary ECDIS backup or a backup portfolio of paper charts needs to be carried.

However;If any of the points listed are not fulfilled the legal value of the ECDIS will be same as an ECS and comparable to a hand held GPS with charts.

*Minimum sensors are required to be connected directly to both stations in order to comply with the ECDIS performance standard requiring a safe take over between main and back-up solution.

Legal aspects and requirements (IMO MC 1.27 C1)A typical system layout can look like this.The ECDIS consist of type approved hardware (Monitor, Keyboard and computer)In addition the system is required to have a set of minimum navigation sensors connected to it.These are:Vessels Positioning system (EPFS)Vessels Gyro (if Gyro not fitted a THD, Transmitting heading device-GPS Gyro)Vessels Log

In case were a secondary ECDIS is fitted as backup the minimum sensors need to be directly connected also to this station.

All other not mandatory sensors can be connected ether directly or via smart network solutions.

Legal aspects and requirements (IMO MC 1.27 C1)Raster Charts Raster Charts (ARCS, Seafarer, BSB, NOS Geo....)Scanned charts - an image!Advantages:Inexpensive to produceSimilar to paper chartsDisadvantages:Dead chart, no Alarms Limited zoom optionsRequires large memory capacityExpensive to correct (a new chart)Only easy to read in north-up orientation

Principal types of Electronic Charts (IMO MC 1.27 C2)Raster Navigational Charts are full-color digital images of the corresponding paper chart. On-screen it looks just like the same familiar paper chart. They have basically two advantages: They are easy to produce, because existing Charts only have to be scanned -and they look like paper charts.Compared to Vector Charts they have several disadvantages. They do not have the capacity to automatically generate an alarm and do not adapt the color scheme according to the draught of the vessel. By zooming out, the display might get cluttered while zooming in to far creates a fuzzy and illegible picture.Operating the Chart in a different than North-up orientation makes it hard to read.Compared to Vector Charts, Raster Charts need a lot more memory capacity and are more expensive to update, since every time a new chart is required.

26Vector ChartsVector Charts (ENC, TX 97, C-Map 93...)Digitalized paper charts- every object is defined and grouped in layers that can be selected within the set safety parameters.Advantages:Automatic alarm generation Optional information (customized settings) Zoom-ableEasy to correctRequires little memory capacity (quick loading) Information can be added (files, pictures etc.)Readability in all presentations (Head-up, North-up, Course-up)Presentation according to the safety parameters of the own shipDisadvantages:Expensive and time demanding production Layout can be a bit different from paper chartsCoding errors even in official ENCs

Principal types of Electronic Charts (IMO MC 1.27 C2)A vector chart is a a database, where different objects are encoded. Your charts software may sort these objects in categories and display them in layers.Advantages:Automatic alarm generation is possibleOptional information can be displayed (customized settings) Zoom-able with no deterioration of the readability They are easy to correctThey require little memory capacity (quick loading) Information can be added (files, pictures etc.)Good readability in all presentation mode like Head-up, North-up, Course-upPresentation is adapted according to the safety parameters of the own ship.The Disadvantages of Vector Charts.The production is expensive and time demanding and their layout can be a bit different from paper charts.
