OIL AND GAS EXPLORATION AND EXTRACTION;
SHALLOW & DEEP WATER
The special issues associated with oil exploration and extraction often
relate to geography and extreme climatic conditions, ranging from
hot, dry desert situations to ship-based units operating a long way
offshore in heavy seas. They also include unpredictable, hazardous and
changeable gas composition. Howden’s custom approach, based on
a thorough analysis of all the factors involved, provides a tested route
to the right compressor package for each unique set of circumstances.
In offshore situations – including FPSOs – weight and size of plant
is obviously critical and the close proximity of personnel to the
equipment makes noise an important health and safety consideration.
The advantage of low power consumption in hard-to-reach situations
is also of major relevance, making Howden oil injected compressor
packages the correct choice.

FLOATING PRODUCTION, STORAGE AND
OFFLOADING (FPSO) APPLICATIONS
screw compressor packages have been developed and
installed onto many of the FPSO facilities around the world. FPSO
vessels can be found in remote and extreme climatic conditions in
deep water locations where they eliminate the need for long, expensive
pipelines from outwells to onshore terminals. Howden’s oil free and oil
injected systems, the product of long experience working with problem
gases, make them eminently suitable for FPSO applications.
The high specification and compact design of Howden systems allow
them to be integrated into an enormous range of ancillary equipment
ready for installation in remote and difficult locations. This makes them
a uniquely efficient choice for process gas compression on FPSOs

OIL AND GAS
Screw compressors have a host of applications throughout the
processing of oil and gas. From the first stages of compressing the
gas to separate out the moisture content and delivering a smoothed
flow into the higher pressure centrifugal compressors when it comes
ashore, right through to the refining stages.
The ability of oil free screw compressors to handle hazardous and
corrosive gases is a particular advantage where the process gas is
inconsistent. They cope efficiently with the sour gases typical of the
late stages of oil and gas fields. The technology is the ideal method
for gases with high sulphur dioxide content, or mixtures with high
levels of dirt and particulates, oil or tars.

PETROCHEMICALS AND INDUSTRIAL
APPLICATIONS
The enormous range of challenges within the petrochemical industries
encompasses extremes of temperature, toxic and hazardous process
gases, and other application-specific demands. In applications as
diverse as butadiene plants and process refrigeration, there are
critical health and safety considerations as well as a need for total
dependability. In such extremes, the benefits of Howden’s bespoke
approach become clear.
Whether supplied as a stand-alone unit or a compete package,
each Howden compressor is designed to match the rigours of its
environment as well as its specific task, and engineered to offer
continuous uninterrupted operation over many decades
