CHART CARRIAGE REQUIREMENT OF SOLAS

6 The mandatory carriage of ECDIS, as required by SOLAS regulation V/19.2.10, is subject to a staged entry into force between 1 July 2012 and 1 July 2018. As per SOLAS regulations V/18 and V/19, for a ship to use ECDIS to meet the chart carriage requirements of SOLAS, the ECDIS equipment must conform to the relevant IMO performance standards.Depending on the date of their installation, ECDIS units on board are required to comply with erformance standards set out in resolutions A.817(19), as amended, MSC.232(82) or MSC.530(106). Essentially, where an ECDIS is being used to meet the chart carriage requirements of SOLAS, it must:

根据 SOLAS 公约第 V/19.2.10 条要求的 ECDIS （电子海图显示与信息系统）强制配备要求，自 2012 年 7 月 1 日至 2018 年 7 月 1 日分阶段生效。根据 SOLAS 公约第 V/18 和 V/19 条，船舶若使用 ECDIS 来满足 SOLAS 的海图配备要求，ECDIS 设备必须符合 IMO 相关性能标准。根据安装日期，船上 ECDIS 装置需符合MSC.232(82) 决议 、MSC.530(106) 决议或经修正的 A.817(19)决议规定的性能标准。本质上，当使用 ECDIS 满足 SOLAS 公约海图配备要求时，必须做到以下几点：

1.be type-approved;

2.use up-to-date electronic nautical charts (ENCs);  

3. be maintained so as to be compatible with the latest applicable         International  Hydrographic Organization (IHO) standards; and

4. have adequate, independent backup arrangements in place.

1.经过型式认可；

2.使用最新的电子海图（ENC）；

3.进行维护以和最新适用的国际航道测量组织（IHO）标准相适应；和

4.安装适当独立的后备装置。

7 According to SOLAS regulation V/18, ECDIS units on board ships must be  type-approved. Type approval is the certification process that ECDIS equipment must undergo before it can be considered as complying with IMO performance standards. The process is carried out by flag Administration-accredited type approval organizations or marine classification societies in accordance with the relevant test standards developed by, inter alia, the International Electrotechnical Commission (IEC) (e.g. IEC 61174).  

根据 SOLAS 公约第 V/18 条，船上 ECDIS 装置必须经过型式认可。型式认可是 ECDIS 装置在被视为符合 IMO 性能标准之前必须经历的认证程序。该程序由船旗国主管机关认可的型式认可组织或船级社按照国际电工委员会（IEC）制定的相关试验标准（如 IEC 61174）进行。

8 In accordance with SOLAS regulation V/19.2.1.4, ships must carry all nautical charts necessary for the intended voyage. As defined by SOLAS regulation V/2.2, nautical charts are issued officially by or on the authority of a government, authorized hydrographic office or other relevant government institutions. Ships required to fit ECDIS and ships choosing to use ECDIS to meet the chart carriage requirements of SOLAS should carry ENCs or, where ENCs are not available at all or are not of an appropriate scale for the planning and display of the ship's voyage plan, raster navigational charts (RNC) and/or any needed paper charts should be carried.  

根据 SOLAS 公约第 V/19.2.1.4 条，船舶必须携带（配备）预定航程所需的所有海图。根据 SOLAS 公约第 V/2.2 条，海图由政府主管当局、经授权的水文局或其他相关的政府机构正式颁布。要求安装 ECDIS 的船舶和选择使用 ECDIS 以满足 SOLAS 公约中海图配备要求的船舶应配备电子海图（ENC），或如果 ENC 根本无法使用，或船舶航行计划的规划和显示无合适的比例，应携带光栅海图（RNC）和 / 或任何所需的纸质海图。

9 IHO provides an online chart catalogue that details the coverage of ENCs together with references to coastal State guidance on any requirements for paper charts (where this has been provided). The catalogue also provides links to IHO Member States' websites where additional information may be found. The IHO online chart catalogue can be accessed from the IHO website at: https://iho.int/en/iho-online-catalogues

IHO 提供在线海图目录，包括 ENC 覆盖范围以及沿海国关于纸质海图要求的导则（如有）。目录也提供至 IHO 成员国网站的链接，这样可以找到更多信息。IHO 在线海图目录可通过 IHO 网站:https://iho.int/en/iho-online-catalogues访问。

10 As per SOLAS regulation V/27, all nautical charts necessary for the intended voyage shall be adequate and up to date. For ships using ECDIS to meet the chart carriage requirement of SOLAS, all ENCs and RNCs must be of the latest available edition and be kept up to date using both the electronic chart updates (e.g. ENC updates) and the latest available notices to mariners. Additionally, ECDIS software should be kept up to date such that it is capable of displaying up-to-date electronic charts correctly according to the latest version of IHO's chart content and display standards.

根据 SOLAS 公约第 V/27 条，预定航程所需的所有海图均应充足并保持更新。对于使用 ECDIS 以满足 SOLAS 公约中海图配备要求的船舶，所有 ENC 和 RNC 都必须是最新可用版本，并通过使用电子海图更新（如 ENC 更新）和最新可用的航海通告保持更新。此外，ECDIS 软件应保持更新，以使其能按照 IHO 最新版海图内容和显示标准正确显示最新电子海图。

11 Relevant appendices of IMO performance standards for ECDIS specify the  requirements for adequate independent backup arrangements to ensure safe navigation in case of ECDIS failure. Such arrangements include: 1) facilities enabling a safe takeover of the ECDIS functions in order to ensure that an ECDIS failure does not result in a critical situation; 2) a means to provide for safe navigation for the remaining part of the voyage in case of ECDIS failure. The update requirements mentioned in paragraph 10 above apply to the backup arrangements as well.

IMO 关于 ECDIS 的性能标准的相关附录规定应有足够的后备布置以保证在 ECDIS 发生故障的情况下安全航行。后备布置包括：1）能安全取代 ECDIS 功能以确保 ECDIS 故障不会导致危急情况的设施；2）在 ECDIS 发生故障时为航程剩余部分提供安全航行的设备。第 10 条所述的更新要求也适用于后备布置。
