NMEA 2000 (IEC 61162-3) provides
for the application of NMEA 2000
aboard SOLAS (Safety of Life at Sea) vessels. IEC 61162-3, which was jointly
developed by the NMEA 2000 Standards
Committee in collaboration with IEC TC
80 Working Group 6, is based on the
NMEA 2000 standard. Equipment
designed to this standard will be able to
share data, including commands and
status, with other compatible equipment
over a single signaling channel.
Single point-of-failure conditions
exist that are capable of disrupting network operation. SOLAS applications
employ redundant designs (e.g., dual
networks and redundant network interface circuits) to reduce the impact of single point failures. The NMEA 2000 standard provides the fundamental tools and
methods to support redundant equipment, buses and messaging.
SOLAS Chapter V contains the
requirement for Integrated Bridge
Systems:
“A failure of one part should not affect
the functionality of other parts except for
those functions directly dependent upon the
information from the defective part. Any
number of redundant buses may be imple-
mented, though typically two will satisfy the
requirements above.”
NMEA and the NMEA 2000 Standards
Committee are devoted to incorporating
new technologies and capabilities into the
NMEA 2000 network. These new
capabilities occur through technical
investment by industry. The NMEA 2000
Standards Committee is committed to an
open dialogue and listening to new ideas
and technologies.
The new target dates for these regula-
tions are as follows:
• Outboard, PWC, and Stern
drive/Inboard up to 500 Hp
– January 1, 2012
• Stern drive/Inboard over 500 Hp
– January 1, 2013
• Boat Evaporative Emissions
Systems – January 1, 2015
For those familiar with the US EPA
regulations, this new timing means the
Canadian regulations take effect after all
of the phase-in and small business provisions expire in the US rule. As a result,
this will greatly simplify the implementation of a Canadian regulation. There
will be some reporting responsibilities
when importing a boat into Canada and
NMMA is working to simplify that as
much as possible.
The Canadian importer is responsible
for ensuring that the engine they are sell-
Marinas in Ontario
continue to lead the way
in protecting our waterways
by participating in the
Clean Marine environmental
program but we would like
to ask the question:
What are YOU doing to
ensure our waterways are
clean for years to come?
