Fairwinds was
utilized by Nucor on a multi-million dollar project.
An entire steel mill was cut apart
section by section in Convent, Louisiana and reassembled
in Trinidad. Nucor asked Fairwinds to fulfill 3 major
roles
First, we were asked to check the components being
moved around the yard on trailers. Some of these pieces
of equipment in the mill were worth several million
dollars and the trailer subcontractor was not going
to be responsible for any damage to what they were
moving. Over the course of the project we checked several
structures for differential deflection at the various
trailer supports and for motion forces while being
moved around in the yard during disassembly. We had
to add steel to several structures to keep them from
overstressing during the field moves. Our engineering
was a valuable resource as none
of the structures we checked became damaged while being
moved in the yard.
Fairwinds second task was to put the structures on
250' x 72' barges for the trip to Trinidad. It was
our responsibility to make sure the structures did
not overstress the barge and also maintained their
structural integrity during the voyage. We utilized
the current codes for seafastening barges in the Gulf
of Mexico. Our Naval architects and engineers made
sure each barge was stable and structurally sound for
each shipment. Fairwinds issued drawings for each barge
showing how the steel mill pieces needed to be fasted
to the barge to safely ship each section. Each barge
required a lot of documentation since each shipment
was insured. Fairwinds engineering for each barge
was first reviewed by the insurance company and second
by a marine warranty surveyor. Each barge load varied
in total weight from 1,000 to 2,500 tons. Fairwinds
engineered a total of 9 barge shipments over a 6 month
period. None of the 9 barges or sections of the mill
that were shipped sustained any damage during their
voyage to Trinidad.
Fairwinds
third task was to check some of the more expensive equipment
and structures for seismic forces. Trinidad is known
for having earthquakes, unlike the original steel mill
location of Convent, Louisiana. Nucor wanted Fairwinds
to engineer the structures to withstand earthquakes
according to the codes required in Trinidad. Fairwinds
checked the structures and issued drawings showing how
to add steel in certain areas to make them sound for
Trinidad earthquake forces.
