Uni-Safe Electronics has announced DNV Type Approval for its
BNWAS BW-800 system.
The new bridge navigational watch alarm system BW-800 complies
with regulations from IMO: MSC.128 (75) and the new IEC 62616
performance standard from February 2010. Uni-Safe Electronics has
successfully delivered more than 800 BNWAS systems. Currently,
Uni-Safe Electronics is expanding its agent network worldwide and is
still looking for new business partners to help make the BW-800
system the "number one" preferred BNWAS brand in the world.
The BW-800 has been tested according to specifications from
the following classification societies: Lloyd's Register of Shipping
(LR); Bureau Veritas (BV); Registro Italiano Navale (RINA);
American Bureau of Shipping (ABS); Det Norske Veritas (DNV);
Germanischer Lloyd (GL); Nippon Kaiji Kyokai (ClassNK); Russian
Maritime Register of Shipping (RS); China Classification Society
(CCS); and, Korean Register of Shipping (KR).
The purpose of a bridge navigational watch alarm system
(BNWAS) is to monitor bridge activity and detect operator disability,
which could lead to marine accidents. The system monitors the
awareness of the officer of the watch (OOW) and automatically alerts
the captain or another qualified OOW if for any reason the OOW
becomes incapable of performing the OOW's duties.
From July 1, 2011, all new ships over 150GT and all new
passenger ships have to be equipped with a BNWAS. When existing
vessels are in dry dock they are normally fitted with BNWAS.
The BW-800 is delivered with a motion sensor as standard.
Normally one to three motions sensors are needed depending on
the bridge design and size. The sensors detect motion on the bridge
and reset the internal timer in the BNWAS. These units are installed
to minimise stress for the officer on watch because he does not have
to activate the reset unit every three minutes, if he moves around
regularly on the bridge. For safety reasons Uni-Safe Electronics has
chosen to use a dual motion sensor with infrared and microwave
detection in order to avoid a "non human" motion to reset the
timer and a single sensor is not suitable for BNWAS systems.
The system is also equipped with an emergency call facility. If the
officer on watch (OOW) needs assistance on the bridge, the BW-800
has an emergency call facility. If the reset unit is activated for more
than two seconds, the back-up officer will be alerted immediately.
Key features of the BW-800 include:
• DNV Type Approval
• High quality and easy installation
• Complies with the new performance standard IEC 62616 (and the
old A.830(19); IMO MSC/Circ.982; IMO resolution A.694)
• Dual motion sensor with infrared and microwave detection
• VDR NMEA data output built-in (no interface box needed)
• Back-up officer selector unit
• Emergency call facility
• Automatic dimmer control

Transas has announced that the "Transas Navi-Sailor" is now
the first ECDIS in the market compatible with the new
Admiralty Information Overlay.
The overlay includes all "Temporary and Preliminary Notices to
Mariners" (T&P NMs) and provides navigationally significant
information from UKHO's ENC validation programme.
The overlay is displayed as a single layer on top of the basic ENC
and it will be available within the standard Transas Admiralty Data
Service (TADS) licence, via the Transas Navi-Sailor ECDIS.
UKHO has developed the new overlay to give seafarers an easy
way to view the information that they need in addition to the
standard chart, to navigate safely and compliantly.
According to Transas, the new overlay will make passage
planning simpler and safer by clearly showing where important
temporary or preliminary changes may impact a voyage. It will also
give seafarers the same consistent picture of the maritime
environment on their ECDIS as they have always had with
Admiralty paper charts.
As a result, shipping companies will be able to comply more easily
with Port State Control (PSC) requirements by providing "T&P MNs"
where they do not currently exist in ENC coverage today. It will also
help simplify their transition to digital navigation.
Soren Andersen, Marine Superintendent, SQE at Nordic Tankers
Marine said: "We are using the Admiralty Information Overlay as
an integral element of our ECDIS-based navigation within the
Transas Navi-Sailor ECDIS. Used as a navigational and planning aid
as part of the company's wider move to adopt ECDIS navigation,
the Overlay is making passage planning and the task of keeping
track of the latest ENC updates much easier. It will also make it
easier for our crews to demonstrate compliance during PSC
inspections. Overall, it has proved to be another important
element in our efforts to continually improve the safety and
efficiency of navigation."
Michael Cauter, Deputy Chief Executive with responsibility for
developing new Admiralty products and services said, "The marine
environment is constantly changing. The Admiralty Information
Overlay is needed because many nations don't yet include
important temporary or preliminary notifications of those changes
in their weekly updates, and even when they are included, they can
be difficult to identify within the ENC. The Admiralty Information
Overlay provides this information on top of the ENC and displays it
clearly and consistently so the mariner can instantly see the impact
of changes on a route and can take appropriate action."
The Admiralty Information Overlay is a further step forward
in supporting the transition to digital navigation and ensuring
vessels continue to sail safely, compliantly and increasingly

new Admiralty Information Overlay should contact their
