This article addresses founda- tions for high-speed, separable, reciprocating compressors from
1000 to 5000 hp (745 to 3728 k W) with
operating speeds of 720 to 1200 rpm.
In many cases, such foundations and
their compressor package attachment
methods are not being adequately designed, specified and installed.
Shale gas production assets have
increased by about 50% in Pennsylva-
nia, West Virginia and Ohio during the
last 12 months. This large increase in
natural gas production requires short
schedules for compressor station de-
sign and construction.
There are two basic foundation cat-
egories for these reciprocating com-
pressors: short-term temporary foun-
dations with operation periods of two
years or less; and long-term perma-
nent foundations with life expectancies
greater than two years and often more
than 20 years. Unfortunately, short-
term foundation designs are initially
utilized for temporary projects that are
extended to long-term projects when
future additional wells are added.
Short-term, low-budget foundations
create excessive vibration due to inef-
fective foundation designs and inade-
quate package attachment methods. In
most cases, such short-term designs
and attachment methods result in high
vibration, unscheduled shutdowns and
require significant modifications to
achieve long-term compressor station
operating life of two to 20 years.
