BS EN 62376-2011 海上导航和无线电通信设备和系统.电子海图系统(ECS).操作和性能要求,试验方法和要求的试验结果
Maritime navigation and radiocommunication equipment and systems. Electronic chart system (ECS). Operational and performance requirements, methods of testing and required test results
This International Standard specifies the minimum operational and performance requirements
and methods of testing for ECS. ECSs are designed or adapted for use as navigation
information systems on vessels not required to comply with Chapter V of the International
Convention for the Safety of Life at Sea (SOLAS).
Different types of vessels, for example, a non-SOLAS passenger vessel, a small fishing
vessel or a recreational vessel, which operate in different environments, need to be equipped
with navigational systems providing functionality to meet their needs. If the full functionality of
ECDIS according to IEC 61174 is considered to be unnecessary, ECS may be suitable for a
navigation information system for these vessels. Governments may consider requiring the
carriage of ECS for these vessels under local arrangements.
In order to provide a standard that can be used to apply different levels of navigational
functionality, three classes of ECS are defined.
• Class “A” ECS are designed or adapted for use as a primary navigation information
system.
• Class “B” ECS are designed or adapted for use as a navigation information system where
less navigational functionality is required than Class “A”.
• Class “C” ECS are designed or adapted for use as a navigation information system with
minimal functionality intended to plot and monitor a vessel’s position.
Within this International Standard, the beginning of each paragraph indicates the applicability
to ECS Class(es). Paragraphs marked “(A B C)” apply to all Classes; paragraphs marked “(A
B)” or “(B C)” apply only to those specific combinations of Classes; and paragraphs marked
“(A)”, “(B)” or “(C)” apply only to those individual Classes.
For a Class “A” and Class “B” ECS, adequate back-up arrangements may be required to
ensure safe navigation in the event of an ECS failure. For a Class “A” ECS, an additional
Class “A” ECS may be used as the back-up. Alternatively, Class “B” ECS are intended to
meet the minimum requirements for adequate back-up arrangements for Class “A” ECS. For a
Class “B” ECS, an additional Class “B” ECS may be used as the back-up. Class “C” ECS are
not intended to meet the minimum requirements for adequate back-up arrangements for Class
“A” or Class “B” ECS.
Guidance for testing ECS is given in Annex A.
