level on “next generation AIS”— what is being called the VHF Data Exchange System (VDES). It promises to deliver higher bandwidth, allowing for additional information to be communicated, and may also include a satellite capability allowing for
two-way long-distance communications via satellite link.
MEJ: Thinking about AIS overall, are there aspects we haven’t discussed that would
be of interest to NMEA members in the US and abroad?
Tetreault: There are efforts in the US and worldwide to start using the additional
capabilities of AIS that I mentioned above, so I’d ask NMEA members to keep an ear
out for them and participate as they can. We recognize that there are important roles
for government, users and equipment manufactures in delivering these capabilities.
The equipment manufacturers play a very critical role, as they provide the interface
between the users and the information sources that governments and others have
and are developing. Also, equipment manufacturers reach a broader audience than
the regulated community that is normally the focus of government efforts. ME

The ITU adopted a new edition to its DSC Standard Recommendation M.493-14 Digital Selective-Calling system for use in the maritime mobile service,
which should be available by about the end of 2015.
Major changes include the addition of two new
classes of DSC: Class H for VHF DSC handhelds and
Class M for DSC man-overboard devices. This new
edition also requires Class D and E radios (
non-GMDSS VHF and HF DSC radios, respectively) to
have an integral electronic position-fixing capability
(e.g. an integral GPS).
Other changes include the restriction of certain
functions, such as barring Class D radios from
requesting a position report and mandating Annex 3
user interface for simplified operation of shipborne
equipment and Annex 4 automated procedures for
simplified operation in shipborne equipment. ITU
also adopted a new edition to its DSC Operation
Standard Recommendation M.541-10 Operational
procedures for the use of digital selective-calling
equipment in the maritime mobile service, though
the changes were not significant.
If you hear of new advancements domestically or
internationally that will affect our industry, please let

Describe both the opportunities and the challenges that marine
businesses in your area face in the years ahead.
• Clientele wanting to upgrade their vessels with newer technologies. These
upgrades will interface their vessel with complete monitoring systems for
navigation and power management. This valuable onboard information on their
display allows the cruiser to travel with confidence.
• Upgrading vessels to meet current NMEA and ABYC standards creates business
opportunities. Aging vessels, along with newer vessels that are being bought and
sold require surveying by a member of the Society of Accredited Marine
Surveyors. The vessels that do not meet the current standards also create business
• Within the Great Lakes region, we have experienced more vessels with corrosion
issues. We have been expanding our knowledge and service equipment to include
complete corrosion analysis on vessels, solving galvanic and stray current
corrosion. Also in this area, we have come across multiple vessels that have been
leaking AC current into the waters, which could have resulted in ESD (electric
shock drowning) incidents. Correcting these issues provides us with satisfaction
knowing that at the end of the day we are saving lives.
• The ongoing challenge is the lack of qualified and motivated individuals that want
to work in the marine industry. Finding qualified technicians with the skill set to
work unsupervised is challenging.
• The time required to keep us up to date with new and changing standards,
attending courses and recertifications. ME
