The Next Evolution
Most gas-charged accumulators are actuated by dry, compressed
air, which can present a number of challenges for operators.
Sys-tems age with use and time; leaks are common, and if proper
maintenance is not performed the air could contain an excessive
amount of hydrocarbons. A hydraulic system leaking air poten-tially
laden with hydrocarbons into areas that may contain haz-ardous
gases can dangerously alter the local fuel/air mixture and create
flammable or explosive atmospheres. Moreover, air that is not
properly treated post-compression can carry moisture into the
accumulators. Wet air can foul hydraulic fluids, degrading system
responsiveness and performance. Additionally, the pres-ence of
moisture within the accumulator gas increases the proba-bility for
internal corrosion of critical components, and endangers the
integrity of the accumulator itself. For these and other rea-sons,
more operators are turning to nitrogen as the actuating gas for
their hydro-pneumatic systems.
High pressure nitrogen provides a number of advantages for
op-erators of hydro-pneumatic systems:
1. It is essentially inert. While reactive under unusual
conditions, nitrogen largely resists combining with other elements
under normal operating conditions. This makes it ideal for use in
explosive atmospheres.
2. It is inherently dry. Nitrogen is by nature a dry gas, with
dew points often -60 F or better. And because of its inert na-ture,
nitrogen effectively displaces other elements within an enclosed
space under normal operating conditions.
3. It is readily available. Most offshore drilling vessels now
have a nitrogen generation system onboard for various
applications.
As a world-class supplier of nitrogen solutions for the oil and
gas market, we continue to look for novel and innovative ways to
support operators on a global scale. Our RigForce compressor series
is energy efficient and designed for continuous operation in the
harshest of offshore environments. Available for both air and
nitrogen service as needed, RigForce is compact and reliable with
the lowest cost of ownership in the industry. Additionally, our
nitrogen generation systems can both create point-of-use ni-trogen
at purities up to 99.5% and compress the generated gas to process
pressures as needed.
As the needs of operators change, we will continue to evolve and
develop new solutions.
Evolve with us.

Vertical Design for Minimum Footprint
BENEFITSImproved Rig SafetyNitrogen is an inert gas. It is
therefore inherently much safer to operate high pressure equipment
such as rig tensioners, motion compensators and blow-out preventers
with compressed nitrogen rather than compressed air.
Compact FootprintBAUERs unique EVO9-NK screw compressor design
coupled with ultra-high-efficiency nitrogen membranes delivers high
performance in an extremely small footprint; and is therefore
suitable for rig retrofits and conversions from air to
nitrogen.
Robust Build for Offshore EnvironmentsAll BAUER NGM systems are
designed to operate continuously under severe offshore conditions
in high salt, high temperature and high humidity environments.
Special 3 coat marine spec paint with offshore surface preparation
is standard.
Bauer Reliability and Low Cost of OwnershipThe NGM system is
designed and built in-house with BAUERs legendary reliability and
low cost of ownership guaranteed. 2 year Warranty, Lifetime Support
Guarantee.
