The wind turbines at the Black Oak
Getty Wind Project in Stearns
County, Minnesota, are 95 meters
from base to top of the tower –
two meters taller than the Statue of
Liberty. Transporting, assembling
and installing 39 of these towers
was always going to be a challenge.
But with torrential rain, lightning
and deep mud to contend with –
completing the project on time
looked like an impossible task.
It took a high-powered performance
from Mammoet to bring 78
megawatts of wind power to the
Minnesota grid on time.
Sempra Renewables’ Black Oak Getty
wind farm generates sustainable power
for 31,000 homes in Stearns County,
Minnesota. Working with the builder,
Amec Foster Wheeler, Mammoet was
responsible for the off-loading,
pre-assembly, installation, tower
cabling and mechanical turn-over of
the 39 Vestas V-110 turbines.
To maximize efficiency and optimize
resilience, the scope of work was split
between turbine technicians, electrical
technicians and crane operators, each
with a dedicated support service
comprising tooling technicians,
mechanics, safety advisors, quality
control and management. To maximize
cost-effectiveness, a fluid approach
was taken to manpower, with personnel
being brought in only when needed.
On top of the predictable challenges,
Mammoet had to overcome a major
unforeseen issue: the weather. The
region experienced exceptionally heavy
rain, which transformed the compacted
soil on which the turbines were to be
erected into a quagmire. With cranes
being used to maneuver large, heavy
sections of wind turbines, maintaining
solid, stable access to the site was
crucial for the project to be completed
safely and successfully.
Mammoet immediately set about
re-deploying personnel and resources
to assist with the changing circum-
stances. To maintain a viable work area,
loose topsoil was removed, drainage
was improved and all crane paths and
work areas were covered with
heavy-duty matting. ‘Stand-down’
procedures were implemented so work-
ers could move to safety when lightning
strikes occurred within a 30 mile radius.
This ensured sufficient resources and
personnel were mobilized to meet the
needs of the project while guaranteeing
safety at all times.
Thanks to Mammoet’s equipment,
manpower and rapid response, the
project proceeded without delay.
The Wind Farm came into commercial
operation on-schedule at the end of
2016.
