36 st / March 2017 www.sea-technology.com or replaced by one that is type ap- proved under the new standard. In some cases, older ECDIS in- stallations will not be upgrade- able. There has been no indication from IMO that the deadline will be extended again, so the pres- sure is on shipowners to take ac- tion well in advance of the August date. Danelec Marine is providing free upgrades of its legacy ECDIS products to meet the new IEC and IHO performance standards. In some cases, this involves swapping out older hardware for new- generation technology; in oth- ers, it's simply a matter of software upgrades, which can be installed by the ship's crew without a service call. Danelec also offers free-of-charge update retraining for navigators already holding a type-speci€c certi€cate on previous ver- sions of the Danelec ECDIS. Why Are New Standards Needed? The new IEC and IHO standards are based on feedback from users and are intended to €x issues that have arisen. Consider, for instance, the following scenarios. ENC Update Status Report. During an inspection, the master is asked to show a report of which cells were up- dated in the ECDIS and when. Under the old standard, it is not possible to pull a full report or overview of updates. The master must look up this information cell by cell. This is tedious and time-consuming and may be prone to errors. Virus Protection. The second mate inserts a USB dongle into the ECDIS in order to update the chart portfolio, auto- matically initiating the update process by an auto-run script. Unfortunately, the USB drive has been infected with a virus from the PC where the chart update was managed. The virus has now been lodged in the ECDIS, creating a potentially disastrous safety risk. Standardization. A shipping company has a number of different ECDIS products from different manufacturers across the …eet. Their displays and operating procedures are very different. Whenever bridge of€cers transfer from ship to ship they must undergo type-speci€c refresher training. This is expensive, time consuming and a potential danger to safe navigation. Alarm Fatigue. Bridge watchkeepers are disturbed by constant audible alarms from the ECDIS when the ship is underway. This is very distracting, and eventually the bridge team may simply get in the habit of ignoring the alarms al- together. Summary of Changes in New ECDIS Performance Standards Changes to IEC 61174 relate to functionality, information presentation and communication. Functionality changes in- clude: availability of ENC updates so chart inventory can be audited internally or by a ship inspector; no auto-run from a USB stick, ensuring virus protection; ability to set a default user setting in a single step; new requirement for anchor costs of purchasing, maintaining and cor- recting paper charts on board. New Performance Standard Since the original ECDIS performance standards were published in 1998, expe- rience in implementing these regulations has revealed a number of weaknesses and problem areas. These issues have been addressed in periodic revi- sions and amend- ments to the standards. The latest major revision was adopted in Au- gust 2015 and will become the norma- tive reference for the type approval of new ECDIS products. The new ECDIS performance standards will provide: improved functionality; safer navigation; enhanced cyber security; more standardization of displays, vocabulary and operation; reduced training needs; and smoother integration with the voyage data recorder (VDR), bridge alert manage- ment (BAM) and bridge navigational watch alarm system (BNWAS). The primary operative documents implementing the new standards are: IEC 61174 Edition 4 – ECDIS operational and performance requirements, methods of testing and required test results; IHO S-52 Edition 6.1 - Speci€cations for chart content and display aspects of ECDIS; IHO S-52 Annex A Edition 4.0 – IHO ECDIS presentation library; and IHO S-64 Edition 3.0 – IHO Test Data Sets for ECDIS. Other relevant documents that affect the new standards include: IMO Resolution MSC.232(82) – ECDIS performance standard; IEC 61162-450 - Digital interfaces for navigational equipment within a ship; IEC 62288 Edition 2 – Presentation of navigation-related information on shipborne navigational displays; IEC 62388 Edition 2 – Shipborne radar – perfor- mance requirements, methods of testing and required test results; IHO S-58 – Recommended ENC validation checks; and IHO S-63 Edition 1.2 – IHO data protection scheme. What Is the Deadline for Compliance? Originally, the revised performance standards were scheduled to come into effect 12 months after their adop- tion, but based on feedback from the maritime community, the IMO agreed to extend the deadline another 12 months. Thus, by August 31, 2017, all newly installed ECDIS equip- ment must comply with the new IEC standards, and already installed ECDIS products must be upgraded to comply with the new IHO standards. Usually when it comes to new standards in marine elec- tronics, existing equipment is "grandfathered" under the existing standards that were in effect when they were type approved, but in the case of the new ECDIS standards there is no provision for grandfathering existing ECDIS products. The International Hydrographic Of€ce (IHO) will withdraw the older editions of S-52 and S-64 August 31, 2017. After that, there will be only one version of the IHO ECDIS pre- sentation library. This means a previously installed ECDIS must either be upgraded to comply with the new standard Danelec Marine's DM700 ECDIS main unit with monitor and keyboard.
