NOTAR® Technology;

HELIUS Helicopter Flying

.01

Minimum Vibrations

A 6th blade to the main rotor system minimizes helicopter vibrations and reduces pilot and crew fatigue.

.02

Reduced Workload

The Coanda Effect provides tail boom lift and anti-torque -- reduceing the sensitivity to wind direction.

.03

Proven Safety

NOTAR® systems eliminate crashes due to due to tailrotor strikes or loss of tail rotor effectiveness.

.04

Noise Reduction

NOTAR-equipped helicopters are among the quietest certified helicopters available.

Installed / Expanded three 345kV Substations including O’Brien, Kossuth, and Webster. Installed 71 miles of MVP 4 transmission line of DC345/ 161kV self-weathering steel monopoles, including removal of existing 161kV transmission line in existing ROW. Includes one 345kV Black Hawk Substation Expansion. Includes all environmental, access roads, QA/QC, safety, steel monopole structures, conductor, hardware and assemblies, OPGW and static wire. Helicopter aided construction, polymer insulators, large drilled pier (cased and slurry drilled) full length anchor bolt foundations. Major outage and return to service constraints were required. All work, including both the transmission lines and substations were performed on an EPC basis.

Siqurd to Red Butte 345kV Transmission Project

Installed a new single circuit 345 kV transmission line, approximately 168 miles in length and supported on single circuit h-frame (majority), monopole and lattice structures, were constructed from Sigurd to Red Butte Substations. This EPC Project included all environmental compliance and helicopter aided construction through the remote access and environmentally sensitive areas. Provided access roads, material yards, site preparation, fencing and gates, foundations, wood, steel and concrete structures, hardware, insulators, conductor, overhead ground wire (OHGW), optical ground wire (OPGW), grounding, clean-up and restoration and all appurtenances such as splices, dampers, and jumpers, all performed on an EPC basis.

Mona to Oquirrh 345/500kV Transmission Project

Mona to Oquirrh 345/500kV Transmission Project

Clover Substation to Future Limber Substation 345 kV Transmission Line Constructed a new single circuit 345 kV transmission line, approximately 68 miles and supported on single circuit lattice steel towers, shall be constructed from Clover Substation to the future Limber Substation. This segment shall be designed and constructed to 500 kV standards including lattice towers, insulation, conductors, hardware and clearances, and energized at 345 kV. This line uses triple-bundled, 1949.6 kcmil ACSR/TW “Athabaska” phase conductors, one ½ inch EHS shield wire and one optical ground wire (OPGW). Limber Substation to Oquirrh Substation 345 kV Transmission Line Constructed a new double circuit 345 kV transmission line, on self-supporting double circuit tubular steel poles, near the future Limber Substation and terminate at Oquirrh Substation at a substation deadend structure between circuit breakers 325 and 345. The work at Oquirrh Substation supported three separate and distinct transmission projects for the Mona- Oquirrh transmission project. 1. Terminate a new Terminal- Oquirrh #3 line in bay 6. 2. Terminate a new Terminal- Oquirrh #4 line in bay 5. 3. Terminate the new Clover-Oquirrh line in bay 5. Bay 5 and part of bay 6 are all new, and follow the pattern of bays 7 and 8. A new 200 MVAR 345 kV shunt capacitor bank was added to the 345 kV north bus. The shunt capacitor bank was located in bay 4, on the south side of the north bus. Control and relay panel additions, modifications, and replacements were required to support the 345 kV additions/modifications. All of the panel additions, modifications and replacements occured within the existing 345 kV control building.

Total distance of 27 miles. Constructed a double circuit line of 500/230kV with (3) 1780 ACSR 84/19 (Chukar) conductors per phase for 500kV and (1) 2156 ACSR 84/19 (Bluebird) conductor per phase for 230kV, plus two OPGW wires utilizing Tubular Steel Poles. Install down leads, cushions, cable racks and OPGW defenders.

Pinal West to Pinal Central 500kV Transmission Project

Pinal West to Pinal Central 500kV Transmission Project

Helicopter Support- Constructed 14.1 miles of single circuit 500kV and 37.3 miles of double circuit 500/230kV electric transmission line on self-supporting galvanized steel pole structures from Pinal West Substation (near Mobile, AZ) to the new Duke Substation (SE of Maricopa AZ and adjacent to the existing Santa Rosa substation) then to the new Pinal Central Substation (807 South Eleven Corner Mile Road). The scope also included an additional 3.0 miles from the PCL substation east, to link to the existing 500/230kV transmission line. The transmission line crossed private property and State of Arizona Lands. Approximately 3 miles of the line route paralleled existing 115/230kV transmission lines. Line crossings included 230kV, 115kV, 69kV, distribution lines, Federal and State highways, Union Pacific RR, El Paso Natural Gas pipelines and irrigation canals.
