About Us Welcome to the Website of Morris Power Construction.
We provide construction for various types of commercial power projects, with primary focus on
renewable energy with wind turbine technology. In additon to wind farm construction projects,
we do smaller wind turbine construction for residental, farms, educational centers, small businesses
as well as both large and small corporations, and office park developments.
The Gulf Wind project, Phase I, consisted of 118 of the largest wind turbines to be constructed in America,
standing 417 feet tall. The wind farm sits on 7,851 acres of the Kenedy Ranch, just south of Sarita, Texas.
Four phases of wind turbine construction are planned for the Gulf Wind, wind farm. Each of the turbines can
produce about 2.4 megawatts of power. With all 118 turbines spinning, that is enough energy to power 80,000
Texas homes annually. An additional 80 turbines are completed by the end of 2009, producing and additional
200 megawatts of power.
Wind turbine construction is a lot more than what meets the eye. Wind turbine construction is a lot more than
nuts and bolts, or blades and volts. There's more to it than that and you are going to get dirty. Demanding
schedules requires that much of the work must be done in sync with when tower sections arrive. Excavation must
be done well in advance so rebar and foundation bolts can be installed and the concrete poured with time to
cure before the base sections of the towers arrive. Scheduling is crucial almost to the minute, so cranes and
operators can be on site to off load the tower sections as they arrive.
Heavy equipment haulers are scheduled on a turn-around basis to return for more tower sections and the turn-around
delivery timing of each section is absolutely crucial in scheduling the work force, cranes and operators. Every item
of material, equipment and the work force must be in sync and any small delay has a dramatic rippling effect of lost
productivity throughout the project in every discipline of work. Supply Managers, Logistic Managers and the workforce
Scheduling Managers must work hand-in-hand with schedules closely monitored with complete coordination among all the
managers, supervisors and foremen.
The structural concrete for the foundations requires specific aggregates to support the weight and the leverage
forces of the wind against the tower and blades. Local area suppliers of the sand and stone must be located and
test cylinders must be made and sent out for lab testing.
Many trucks and drivers must be located to haul the aggregates to the project where blending and mixing are done
on site as the demand requires. Often many trucks and drivers are brought in from other areas to meet the demand.
Multiple contractors and subcontractors join forces in the construction of wind farm projects. Many contractors
meet again and again on various wind farm construction projects from coast to coast. This is demanding work for
contractors as the wind farm projects are scattered from state to state across the country.
Another type of concrete is placed over the cables as they are being trenched to the sub-station. This is called
FTB, which stands for Fluidized Thermal Backfill and requires a completely different type of aggregates to produce
the thermal capability to take heat away from the buried power cables.
FTB (Fluidized Thermal Backfill) is a type of concrete put over buried power cables to dissipate heat. Thermal
backfill is most important in wind farm construction as wind speeds increase, wind turbines produce more power.
When multiple turbines are attached to the same cables leading back to the substation, heat will increase
significantly with wind speed.
To backfill with dirt or sand will not offer any heat dissipating qualities. FTB (Fluidized Thermal Backfill)
is carefully blended with specific aggregates that are designed for dissipating heat away from buried power
cables. FTB (Fluidized Thermal Backfill) protects buried power cables from overheating during wind surges.
FTB (Fluidized Thermal Backfill) dissipates heat and works to prevent power cable burnout.
Wind turbines, these modern marvels of modern day man not only require precision in manufacturing and assembly,
but also require a coordinated precision to the timing of deliveries and the scheduling of the required workforce.
