HSSC 7 Action Item

INTERNATIONAL HYDROGRAPHIC ORGANISATION HYDROGRAPHIQUE ORGANIZATION INTERNATIONALE ENC STANDARDS MAINTENANCE WORKING GROUP (ENCWG) [A Working Group of the Hydrographic Services and Standards Committee (HSSC)] Chairman: Thomas MELLOR United Kingdom Hydrographic Office Admiralty Way Taunton, TA12DN United Kingdom Telephone: +44 (0)1823 337900 Facsimile: +44 (0)1823 284077 E-mail: [email protected] Secretary: Tony PHARAOH E-mail: [email protected] Ref: ENCWG Letter: 2/2016 To: ENCWG Members Date 18 August 2016 Checking the IHO presentation Library edition number in the ECDIS Dear All, In response to the HSSC 7 action under 7.2 IMO the ENCWG is to provide guidance for Original Equipment Manufacturers (OEMs) to include in their user guides on how to check the IHO Presentation Library edition number. I propose to circulate the information contained in Annex A to them and to also include it on the IHO web site. This information will also be promulgated to Port State Control inspectors to inform them that the old ENC Check dataset for use in ECDIS running S-52 preslib 3.4 is not compatible with the new Presentation Library edition 4.0 and for this reason the checks should not be run on ECDIS that have been upgraded. I invite you to provide your approval or comments on the proposed document at Annex A. Best Regards, Thomas MELLOR Chairman, ENCWG Attachment: Checking the IHO presentation Library edition number in the ECDIS.  Annex A Checking the IHO presentation Library edition number in the ECDIS Background - IHO ENC Check dataset In October 2011 the International Hydrographic Organization (IHO) issued the ENC check datasets, which comprised two fictitious ENC cells intended to assist mariners to identify if their ECDIS was using the latest edition of the IHO Presentation Library, (Edition 3.4 at that time). The dataset was also designed to highlight if there were any known ENC display anomalies present in their system. Mariners were asked to run a series of quick tests using the check datasets within the ECDIS and to report whether they were experiencing any display issues. If their system was found to be running an earlier edition of the IHO Presentation Library, or if they had a more serious display anomaly, mariners were advised to contact their ECDIS manufacturer or an appropriate equipment maintenance company to obtain software patches and investigate further to resolve the issues. Results of the tests were sent to the IHO for analysis and for use in revising IHO standards. The content of individual tests has been kept confidential. To address the display anomalies and to improve the ECDIS user experience, the IHO issued S-52 Presentation Library Edition 4.0 in September 2014. The biggest benefit of upgrading ECDIS systems to the latest IHO Presentation Library will be a reduction in audible alarms, which will ease the issue of alarm fatigue on the bridge whilst maintaining safety at sea. The introduction of an alert model based on the requirements in the IMO ECDIS Performance Standard, will also harmonize ECDIS behaviour across different manufacturers systems. A number of new symbols have been added to the IHO Presentation Library. These symbols will identify features that require an indication highlight, the location of automatic ENC updates and ENC features that have a temporal attribute. A number of other significant changes in the Presentation Library have come directly from Mariner feedback. For example, the names of Fairways and Anchorage Areas will now appear on the ENC display and a “hover over” function for certain charted features has been introduced. The IHO co-ordinated with the International Electrotechnical Commission (IEC) to align publication issues dates and in just less than a year the IEC published IEC61174 Edition 4.0 in August 2015. These standard updates affect all new ECDIS systems and new installations from August 19th 2015. For exiting ECDIS they have until August 31st 2017 to update their systems so that they comply with the guidance in MSC.1.Circ.1503. It is an existing requirement for all ECDIS to have a function to display the edition number of the IHO Presentation Library (PresLib) that is in use within the ECDIS. The new IHO ECDIS Presentation Library edition 4.0 clause 19.1 states ‘The edition number of the PresLib installed must be available to the Mariner on request’. This requirement is tested in IEC61174 edition 4 clause 5.5.1 Presentation library (S-52/Annex A, Part I/19.1). The edition number of the PresLib installed shall be available to the Mariner on request. All Mariners must familiarise themselves with the function in their ECDIS that will display the edition number of the IHO Presentation Library as this varies across ECDIS manufactures. This function will be required when Port State Control officers want evidence that the ECDIS is up-to-date to the latest IHO standards. The Mariner can also check the ECDIS is capable of displaying the new symbols introduced in the IHO Presentation Library edition 4.0 by opening ECDIS Chart 1. ECDIS chart 1 is a legend of symbols used within ENC charts and is installed on all type approved ECDIS systems. The new symbols introduced in IHO Presentation Library edition 4.0 are shown below; Magenta ‘d’ symbol for features that have date dependent attributes populated. Indication highlight symbology for objects that pose a danger to the vessel. Automatic update symbology for identifying where changes to the ENCs have occurred. Viewing ECDIS Chart 1, Information about chart display (A,B) within the ECDIS will display the new symbols if the IHO Presentation Library edition 4.0 is installed. If the ECDIS has not been updated then you will not be able to view the new symbols. This is the IHO recommended method for checking the ECDIS system can display the new symbols correctly. There is currently no intention for the IHO to issue a check data set for IHO Presentation Library edition 4.0.
