Solutions for
LNG Facilities

The first shipment of natural gas was transported to shores in1944 in the form of liquefied natural gas (LNG). Today naturalgas is used in more than 63 million homes and is utilized fora variety of purposes including electricity generation andpetrochemical feedstock.
The use of LNG is a proven, reliable, and safe process, andnatural gas is quickly becoming the world’s cleanest burning
fossil fuel as it emerges as the environmentally preferredfuel of choice. It is for this reason that LNG facilities are put
under more pressure than ever to meet the world’s natural
gas demand. Keeping your plants running at an efficientpace is vital to production and condition monitoring plays acritical part in this process. Condition monitoring provides a
proactive approach so that maintenance can be planned,
eliminating unscheduled outages and optimizing machine
performance. In addition, condition monitoring helps toavoid breakdowns with subsequent secondary damage
and loss of production revenue meaning that today’s LNG

The business case
Machinery protection and asset condition monitoring systems are an investment that pays back quickly and in numerous
ways. Today, such systems have moved from simply “good engineering practice” to “good business practice.” And for goodreason—they have proven their value time and again in not just the LNG industry, but nearly every industry that depends upon
its machinery’s availability and output to meet its business goals.

Examples of LNG
liquefaction process
Bently Nevada has installed condition monitoring solutions in facilities such as yours for over 50 years. Below are just two
examples of liquefaction processes used in many LNG facilities today where Bently Nevada has long been regarded as thepartner of choice for machinery protection and monitoring.

Payback through protection

ConocoPhillips Optimized Cascade® LNG Process†Our solutions help protect your machinery from catastrophic failures and their costs.
For more than 50 years, the Bently Nevada name has been recognized for its industry leadershipin machinery protection and condition monitoring. Today, with more than one million channels ofmachinery protection installed worldwide, customers have made us the proven choice for machine
protection. We not only protect your machinery, but our legendary product quality, deep application
expertise, and highly competent locally available service help protect your condition monitoring
investment as well.

Payback through mechanical validation

Our solutions let you capture baseline machinery conditions, pre- and postmaintenance, giving you a reference for optimal decision making.
One of the most crucial times in the life of a machine is immediately after maintenance has been
performed. We can tell you if “all is well” with systems that capture relevant data both before and aftermaintenance. You can instantly see if problems are present and make decisions accordingly. For manycustomers, the ability to knowledgeably continue with or abort the startup of a turbine-generator train
can more than pay for their entire Bently Nevada monitoring system, in a single event.

Payback through predictive maintenance

APCI Propane Precooled Mix Refrigerant Process

Our solutions deliver information that allows you to perform maintenancewhen conditions—not calendars—dictate.
Unplanned downtime can be detrimental to your plant operations. All LNG facilities operate at different
production rates but by knowing the health of your assets, you can plan for repairs rather than react tofailures. Employment of a condition monitoring solution in your plant increases availability and reduces
downtime. Managing processes and equipment through predictive maintenance presents significant
benefits. With the rapid evolution of technology, LNG facilities such as yours can obtain a higher levelof intelligence while simultaneously monitoring plants and assets, reducing downtime and ultimately
cutting costs by understanding operational risk for strategic decision making.

Measurable results, tangible value
Plant-wide value through condition monitoring occurs asset-by-asset. Our solutions for LNG facilities encompass not justyour most critical equipment where downtime is the dominant economic driver and can reduce or even halt plant output, butalso your less critical assets where maintenance and labor costs are of primary concern. Below are just a few examples of thedozens of different asset types we can address.

Gas Turbines
Bently Nevada has provided machinery protection and condition monitoring for
gas turbines for decades. Our comprehensive solution combinesprotection with state-of-the-art condition monitoring hardware and software fortrending high-resolution data capture surrounding an alarm, as well as
high-resolution data capture during startup, shutdown, and overspeed conditions.
By combining this functionality with additional Bently Nevada modules such as
Thermodynamic Performance monitoring, Predictive Emissions Monitoring System(PEMS), and Decision Support capacities, we will help you manage these assets
with full confidence.

LNG facilities may include hundreds of Fin Fans (often referred to as Heat
Exchangers or Air Coolers). Given the criticality of these assets, Bently Nevada
recommends the use of our Trendmaster Dynamic Scanning Module (DSM). The
DSM is an online periodic condition monitoring device that is capable of connecting
to thousands of sensors (including vibration, temperature, speed, and process
variable information). The acquired static and dynamic data is then sent to System
1 for trending, alarming, and and advanced vibration diagnostics. If desired, the DSM
is capable of sending static data directly to a third party system such as a DCS. Inaddition to the DSM, Bently Nevada offers various options for continuous monitoring,predictive maintenance, and protection of Fin Fans, including portable vibration
analysis which has proven to be a valuable tool for monitoring these assets.

Centrifugal Compressors

Pumps

Centrifugal compressors are a critical component to LNG facilities. Bently Nevada
solutions have successfully protected and managed these assets for decades.
Our solution set combines the protection from our 3500 System (or latest Orbit
60 platform), with the management capabilities of System 1. Our modular
approach allows you to select the solutions to meet your needs. Examples
include Thermodynamic Performance monitoring and Decision Support
capabilities. In particular, monitoring the performance and health of dry gas
seal systems on these compressors is an ideal application for System 1 Decision
Support analytics engine.

Electric Motors

AC Motors—both fixed or variable speed—require a variety of specialized
protection and condition monitoring solutions depending on criticality,
horsepower, duty, and the type of machinery they drive. For highly critical motor
driven applications, such as cryogenic pumps, compressors, cooling fans, etc.,
condition monitoring techniques may include vibration, temperature, speed,
and phase measurements. An innovative approach for motors, especially thosethat are difficult to access or are submerged is AnomAlert† Motor Anomaly
Detector. This solution utilizes motor current and voltage transformers to build an
operational model, from which real time condition and incipient fault symptoms
can be assessed. The user interface will automatically advise on electrical AND
mechanical anomalies associated with the motor and the driven load. Corrective
action to the electrical supply, stator, rotor, bearings, or abnormal load fromclogged filters, for example, is available from AnomAlert.

8Fin-Fans

Pumps are plentiful and absolutely vital to the operation of LNG facilities.
Unfortunately, pump failures can impact more than just maintenance costs andproduction losses—they can result in failures that may be catastrophic to youroperations and staff. Our solutions for monitoring pumps detect and address
the mechanical and Thermodynamic Performance conditions that—whenleft unchecked—can lead to seal leaks, bearing destruction, and other costlymalfunctions. To ensure that an economical yet appropriate solution exists for thespectrum of pumps, we offer portable instruments, conventional wired systems
for online monitoring, and innovative new wireless technology that makes thebenefits of online monitoring economically feasible for a larger percentage of yourassets while reducing installation costs.
Pictured is Ebara Cryodynamics’ LNG pump test facility, Sparks Nevada, USA, featuring
a nine stage submersible LNG Sendout Pump (265 m3/hr at 1722 m TDH, -158®C,900kW). This pump is also at the heart of a South Korea LNG Terminal.

Reciprocating Compressors
Reciprocating compressors play an important role in the LNG process. Bently
Nevada is proud to be a leader in the protection and condition monitoring of theseunique assets. Our solution includes specifically designed sensors, 3500 protection
and data acquisition modules, and System 1 condition monitoring software. This
combination allows for the collection of both static and dynamic data for trending,high-resolution data captured on alarm, as well as diagnostic capabilities
including: cylinder performance, rod load calculation, cylinder pressure,crosshead vibration, frame vibration, rod position, speed, temperature, and more.
By incorporating our new Decision Support capabilities, you can automate thedetection of complex malfunction types, such as cylinder valve leaks, pressure
packing case leaks, loose pistons, loose cylinder valves, and many others so thatmachinery stake holders can proactively plan maintenance activities.
