Installation of a GE 7FA Gas Turbine on
Vibro/Dynamics SVXN Spring Isolators
Waller Marine set forth on an ambitious project
to design and build two floating power generation
barges to provide Caracas, Venezuela with needed
power. Each barge was powered by a GE 7FA dual
fuel industrial turbine, producing 171 MW generating
capacity, weighing 650 tons and developing
Waller Marine and subcontractor, Berger ABAM,
determined that a pre-stressed, reinforced concrete
plinth supported by low-frequency, spring isolators
was the best solution. Berger ABAM contacted
Vibro/Dynamics, known for their expertise in designing
isolation systems, to assist them in the final design of
the isolation system.
Several isolation models with varying stiffnesses
and damping types were considered and analyzed.
The analysis showed that a low-frequency, viscous
damped, coil spring isolator was required.
Vibro/Dynamics quickly went to work, designing
a custom SVXN to meet the
required specifications and design requirements.
Vibro/Dynamics delivered and met a very aggressive
schedule set by Waller Marine.
