To inform you about how ADMIRALTY Products and Services are affected by the COVID-19 crisis UKHO is publishing information in this README file and as a downloadable PDF document on the public website at admiralty.co.uk/admiralty-partners/COVID-19. UKHO will keep the document updated on the web site as new information becomes available and maintain communication via ADMIRALTY Chart Agents for safety related information or significant product impacts. France. 7 April 2020: The French Hydrographic Office (SHOM) have confirmed that, having stopped the broadcasting of Notices to Mariners and corrections to ENCs after week 12 due to anti COVID-19 containment measures, Notices to Mariners and production of corrections to ENCs resumed from week 15. Norway. 31 March 2020 The Norwegian Hydrographic Service has implemented several measures aimed at minimizing disruption to the delivery of navigationally important publications. All employees are now working remotely and the Notice to Mariners and updates to ENC and paper charts are being produced as normal. Portugal. 31 March 2020 The Portuguese Hydrographic Office has advised that their March publication of Notices to Mariners will be delayed until the end of April. Mariners should therefore be cautious when using ADMIRALTY charts and publications that cover areas of Portuguese responsibility, until normal service resumes. ENC updates are not affected. Philippines:19 March 2020 We have been notified of the following from the Philippines Hydrographic Office; “Due to the recent Government imposition of the Enhanced Community Quarantine for the whole island of Luzon, the NAMRIA - Hydrography Branch will stop its regular activities until further notice. Navigational Warnings and monthly Notices to Mariners will still be promulgated in order to ensure safety of navigation. We remain committed to safety and will continue to keep you updated with safety critical information.” United Kingdom. 3 April 2020 No delays to Notices to Mariners, new chart editions or ENC updates. ----------------- NUMBER OF PERMITTED INSTALLATIONS ----------------- The End User Licence Agreement (EULA) governing the use of AVCS data permits its installation on a maximum of 5 workstations on any licensed vessel. It further recognises that some parts of the data may be installed on more or fewer workstations. ENCs with the following producer codes may be installed on the maximum number of workstations indicated: Unlimited workstations on a single vessel or 5 workstations at a single shore-based location AL, AR, AU, BD, BE, BH, BR, CL, CO, CU, DE, DK, EC, EE, EG, ES, FI, FR, GB, GE, GR, HR, I1, IS, IT, LT, LV, ME, MX, NL, NO, NZ, OM, PE, PH, PK, PL, PT, RO, RU, SB, SE, SR, TR, UY, VE, ZA Also: additional datasets from 1U Up to 3 workstations C2, MS, SG, TH --------------------- ENC UPDATE STATUS The latest update status of every ENC in AVCS is listed in the file ENC-Update-List.csv located in the INFO folder on this disc. The file lists the edition number and update numbers and dates for each ENC, correct in the week of publication. The most recent 4 weeks of status files can be found in the ADMIRALTY Vector Chart Service updates section of the UKHO website at admiralty.co.uk/avcs. --------------------- INTERIM CATEGORY OF ZONE OF CONFIDENCE IN DATA (CATZOC) VALUES The boundaries between Quality of Data (M_QUAL) areas with different CATZOC values for some ENCs have been taken from the Source Diagram (SD) on the equivalent paper chart and they should therefore be considered to be approximate. For these M_QUAL areas, the CATZOC values are based on the simplified summary provided in the SDD and therefore represent the lowest categorisation assigned to any survey in each defined group of surveys. The simplification means that it has not been possible to identify minor gaps within survey coverage and mariners should be aware that such gaps (where lower quality survey data has been used in the compilation of the chart) may exist. These assessments are based on original survey accuracies and on expectations of good practice by relevant survey authorities. Some evaluations may require downgrading once detailed survey information has been examined. --------------------- OVERLAPPING ENCS IN THE SAME USAGE BAND Some data providers issue ENCs which contain overlapping data coverage, both internally and with adjoining nation’s coverage. This may make them difficult to use in certain ECDIS systems which default to displaying both overlapping cells. Caution should therefore be exercised when using such overlapping data. Mariners should be aware that there will be a possibility that items of significance may be present only in one data set within an area of overlap. They should therefore take care to examine both data sets when planning a voyage through such an area. ============= SECTION 2 - HYDROGRAPHIC OFFICES´ INFORMATION --------------------- AU (Australia), PG (Papua New Guinea) and SB (Solomon Islands) ENC (published by AHO) - Updated 9 April 2020 ------ Australian Hydrographic Office (AHO) publishes AU, PG and SB ENCs covering Australian, Australian Antarctic Territory, Papua New Guinea and Solomon Islands waters. GUIDANCE ON ECDIS FOR SHIPS CALLING AT AUSTRALIAN PORTS – 9 April 2020 When entering Australian Ports please be reminded of the AMSA Marine Notice 7/2017 (https://www.amsa.gov.au/vessels-operators/regulations-and-standards-vessels/marine-notices) which highlights areas relevant to the safe and proper operation of ECDIS for ships visiting Australian ports and provides information on AMSA's expectations for ECDIS compliance during Port State Control (PSC) inspections. Ships found not complying with AMSA Marine Notice 7/2017 may be detained. AMSA are concerned with software quality assurance in ECDIS and detection of operating anomalies using the ECDIS Data Presentation and Performance Check dataset. Other areas of interest include chart carriage requirements, mode of ECDIS operation and ECDIS training requirements. Specifically PSC inspectors will take account of: * appropriate declaration of ECDIS equipment in the Record of Equipment - Safety Equipment Certificate * listing of ECDIS as critical equipment in the Safety Management System (SMS) * documented procedures and instructions for use of ECDIS are included in the SMS and that they are understood by all officers responsible for navigation * ECDIS type approval certificate, confirming compliance with relevant IMO performance standard and the International Electrotechnical Commission (IEC) test standard * ECDIS software is maintained to the latest applicable IHO standards * use of latest edition official ENCs, updated and corrected to the latest available updates and notices to mariners * adequate independent back-up arrangements (as detailed on the Record of Equipment), ensuring safe navigation for the remainder of the voyage in the event of an ECDIS failure * approved ECDIS generic and familiarisation training has been undertaken by the master and officers in charge of navigation * conformance and alignment with input from sensors (e.g. heading, speed and rate of turn) and presentation of such information on the ECDIS display * evidence of periodic tests and checks of the ECDIS carried out in accordance with the SMS and the manufacturer's requirements * demonstration of operational competency by the ship's navigating officers (e.g. safety checking of a voyage plan) * ECDIS settings are appropriate to the ship's dimensions and area of operations (e.g. cross track error, anti-grounding cone, safety depth and contour). UPDATES - Updated 9 April 2020 Updates for AU, PG and SB ENCs published by the Australian Hydrographic Office are issued weekly. They include all Permanent, Temporary and Preliminary Updates. For updates to Australian Hydrographic Publications (nautical publications), and any Paper Nautical Charts used as a backup to ECDIS, mariners should consult the fortnightly Australian Notices to Mariners available via the AHO website at www.hydro.gov.au. IMPORTANT NOTICE - Updated 9 April 2020 All AU, PG and SB ENCs published by the Australian Hydrographic Office include all significant hydrographic information assessed as suitable for use (including data which may be of known or unknown quality) at date of compilation. Significant changes are promulgated via ENC Update or ENC New Edition as appropriate, as well as by Australian Notices to Mariners. All reasonable efforts have been made to ensure the accuracy and completeness of the information, including third party information, incorporated in this product. The AHO regards third parties from which it receives information as reliable, however the AHO cannot verify all such information and errors may therefore exist. Where possible, indications regarding the reliability of information are noted or symbolised in the product. Users should familiarise themselves with the meaning of any notes or symbols, including those described in AHP20 Mariners Handbook for Australian Waters. The AHO does not accept liability for errors in third party information or the inappropriate use of Australian published ENCs.

This information is not intended to correct CNHO products but may be significant to navigation. CNHO (C1) ENCs are not updated for this information, which may include changes to routeing measures and port developments. --------------------- KR (Republic of Korea) In WK02/2020 Korea removed the following 20 existing Band 6 ENCs from sale. Korea have informed us that these ENCs are still valid for use by existing licence holders and they will continue to be updated until the end of 2020, when all licences will have expired. ENC Removed Title KR4F4D40 Jinji Man and Approaches KR4F4N30 Title Not Specified KR4G3A30 Jinhae Man and Approaches KR5F2J23 Yeonpyeongdo Hang KR5F2K24 Title Not Specified KR5F2O13 Taean Hang Anheung Hamg KR5F4C32 Plans on West Coast of Korea KR5F4F33 Plans on West Coast of Korea KR5F4G23 Title Not Specified KR5F4K13 Title Not Specified KR5F4K14 Dodu Hang Wimi Hang KR5F4K23 Jeju Hang Seogwipo Hang KR5F4N34 Approaches to IEODO KR5G1J31 Samcheok Hang KR5G1J34 Plans South Part Korea E Coast KR5G1N32 Hupo Hang to Ganggu Hang KR5G3B32 Ulsan Hang (Onsan) KR636A16 Title Not Specified KR647A80 Title Not Specified KR688A88 Title Not Specified Because these ENCs have not yet been cancelled, the polygon limits may continue to show on catalogue displays, even though they can no longer be purchased or renewed. To remain compliant, vessels should routinely check their planned routes to make sure that they have purchased all other ENCs under their track. --------------------- 1U (Taiwan) In addition to official GB ENCs, extra information in the form of datasets issued by Taiwan, has been included in AVCS to assist with safe navigation and for use entirely at the vessel's risk. For vessels navigating in coastal waters or entering ports of Taiwan, local authorities may require this data to be used on ECDIS to meet their chart carriage requirements. Because the producer is not listed as official by the International Hydrographic Office, the Taiwan datasets may show up in ECDIS displays as "non-ENC" or "unofficial". For compliance purposes the local authorities have stated that the indication can be ignored. ============= SECTION 3 - WITHDRAWN CELLS - Updated 07-May-2020 --------------------- WITHDRAWN ENCs ENCs may be withdrawn from ADMIRALTY services without the issue of a cancellation update because of concerns about their content or overlap with other data. The withdrawal of ENCs is communicated in this README.TXT file and in Section VIII of the ADMIRALTY Notices to Mariners Bulletin. The following ENCs are currently withdrawn from ADMIRALTY services: None If withdrawn ENCs are installed in your ECDIS, you are advised to use them with caution and refer to the appropriate paper chart coverage as they may be out of date. ============= SECTION 4 - MISCELLANEOUS INFORMATION - Updated 07-May-2020 ---------------------------- COPYRIGHT: (C) Crown Copyright 2020.
