The first live installation of MarFlex’s NQZR
all-in-one electric cargo pump package will
be on a product carrier in 2012.
Following strong interest, the pump was
initially being targeted at the inland barge
market. The change in direction means it is now
undergoing modification for application in the
MR sector, a segment the MarFlex group has been
supplying for 15 years.
While the components for a product tanker
remain the same, the size of the unit is being
scaled up and the in-house mechanical research
and development team is working on incorporating
temperature and pressure sensors inside the
pump. All of the trials and testing of the pump
are undertaken at the MarFlex plant prior to
installation, which means that a fully operational
system can be supplied direct to the vessel.
“We changed our focus from inland to seagoing
tankers because the NQZR provides a level of
functionality that is not needed on inland trades,”
explains MarFlex owner, Paul van Beveren. “On
inland barges you generally don’t have frequency
converters, which are pretty central to the MarFlex
NQZR concept. Secondly, from a communications
point of view, inland barges having a limited trading
profile, such as north west Europe, which means it is
very easy to contact the vessel using a conventional
mobile phone. NQZR can be monitored and
maintained via satellite. In short, the system is too
advanced and too expensive for inland needs.”
Mr van Beveren says that yards continue to
respond positively to NQZR. Typically, when a cargo
system is ordered one company will deliver the
pump and others will deliver the various monitoring
systems. “We believe an integrated package is both
logical and safer, and offers the benefits of predictive
maintenance. For shipyards our package means
that they deal with only one turnkey supplier.”
In discussions with owners, one of the recurring
questions according to MarFlex electrical and
instrumentation engineer, Kees de Visser van Hoorn,
is whether the company can supply conventional
sensors as part of the package, for example rigid
air bubbling or mechanical sensors instead of the
MarFlex smart sensors.
“This is possible. As far as possible we put in
remote input/output stations for communication
with other parts of the system. Also we have a
staged system, in line with class rules. This means
that there is always one point of operation, whether
global, local or remote control. When people ask
‘what can I supply’, I can respond: ‘what do you
want?!’ According to their wishes and class rules
we adapt it to the NQZR-concept.”
Another segment showing strong interest in
the system is offshore. “On an FPSO, for example,
the pumps, operational cycles are more intense
than when on a seagoing tanker. During scheduled
maintenance, the idea of being able to look at
one complete unit is appealing from a time and
efficiency point of view.”
MarFlex will start work on developing two new
cargo pumps for this market later this year, with
a view to a commercial launch in summer 2012.
Features of the new pumps will include higher
capacities and higher pressures, and they will also
incorporate seawater lifting pumps. TST
Following the launch of its new all-in-one electric cargo pump package last year, Dutch company MarFlex is preparing a complete system for a trial installation on a MR product tanker

Briefing: the MarFlex NQZR pumpThe MarFlex NQZR pump system incorporates
all the elements required for cargo monitoring
and measurement, such as temperatures,
pressures and level gauges.
Monitoring is made possible via two multi
core cables which attach the NQZR touch
screen to an on deck junction box. From
this one centralised point all field cables
connect to the measuring equipment. The
sensors for cargo temperature and tank
pressure are already integrated in the pump
itself but all sensors are connected to the
explosion-proof junction box. From there tank
and process data pass through the barrier
cabinets and converter cabinets to the NQZR
touch screen.
Using a cargo overview window set up in
the cargo control room, it is possible to start
one of the deepwell pumps and simultaneously
monitor the cargo temperature. The ballast
overview screen works in essentially the same
way, handling a ship’s ballast pumps.
Both on board and on shore, NQZR allows
for real time monitoring in a web browser via a
secured connection. A text message or e-mail
can also be sent to onshore recipients. In this
way crew and owner can quickly diagnose the
situation. After any performance degradation,
MarFlex can predict failure moments and plan
maintenance to prevent maintenance stops.
