APPLICATION FOCUS
EXPERTS IN MARINE VAPOR
RECOVERY SYSTEMS
STRONG TRACK RECORD
AND GLOBAL SUPPORT
The majority of our activities
in MVR involve supplying gas
analyzers to OEMs, though
it may also involve updating
analyzers in older systems.
System designs have become
well-developed and the
technology is long-proven, so
the performance and cost-
of-ownership benefits of the
Servomex solutions mean
we have become the go-to
supplier for all the major
manufacturers of marine vapor
recovery systems.
Servomex has provided fixed and portable gas analysis solutions to
the Marine Vapor Recovery (MVR) sector for more than 30 years.
SERVOMEX SOLUTIONS FOR MARINE VAPOR RECOVERY
For oxygen monitoring, two
Paramagnetic analyzers are
required, as regulations insist on
redundancy within each system.
Our solution provides either the
SERVOTOUGH Oxy 1900 or
SERVOTOUGH OxyExact 2200,
which both use Paramagnetic
technology and meet the
necessary certification for use in
hazardous areas.
Paramagnetic sensors offer a very
good response time, and use no
consumable parts, providing
many years of service. While
initially more expensive than
electrochemical cells, they have a
much longer lifespan, are non-
depleting, and require infrequent
calibration, so are much better
value in the longer term.
Another important MVR
monitoring requirement is
emissions reduction. Where
vapors are recovered by any
means, operational performance
is monitored by using a
hydrocarbon analyzer. Typically a
multi-gas Infrared analyzer is also
used to monitor combustion by-
products, as they function effectively
in air or inert gas environments.
To control emissions during
vapor recovery or destruction,
the SERVOTOUGH SpectraExact
2500 Infrared analyzer is used
to monitor hydrocarbons, while
the SERVOPRO 4900 Multigas
monitors combustion by-products
such as carbon monoxide and
sulfur dioxide.
“Our systems for the marine industry deliver proven performance and reliability.
Together with our excellent field support, this has enabled us to build good
customer relationships and a strong reputation as a turnkey solutions provider.”

EXAMPLE MARINE VAPOR RECOVERY SYSTEMS
We have supplied more than
100 systems to the USA, and
many more globally. This strong
track record has placed us at
the forefront of marine vapor
recovery gas analysis as a turnkey
solutions provider for OEMs.
This is supported by extensive experience in supplying all the major
petrochemical companies globally with similar redundant-analyzer
systems for safety-critical processes.
As cargo is transferred into tankers, either from ship-to-ship transfer
(lightering), or from shore-based facilities such as refineries and
terminals, vapor generation occurs.
Vapors containing volatile organic compounds (VOCs) are often
combustible, presenting many hazards, including cargo tank
overfilling, cargo spillage, and fire/detonation.
Large volumes of these vapors are generated during tank filling, and
must be either vented or ‘recovered’. Gas monitoring is important
during these activities to ensure the safety of the vessel, terminal, and
personnel, and to reduce harmful emissions.
Vapor control, however, introduces hazards of its own, including the
possibility of over or under pressuring the tanker, and introducing an
extra risk of ignition. This increases the need for accurate monitoring,
and has led to stringent rules governing the systems involved.

In addition, our global service
network is a major benefit
for end users, who can rely on
rapid, expert support if their
dock skid requires maintenance
or repair. We understand that
continuous uptime is essential
for logistics companies, and have
the structure in place to get
processes up and running fast.
