Storm Damage Assessment After Hurricane Ian

Storm Damage Assessment After Hurricane Ian

Storm Damage Assessment After Hurricane Ian

Type: Storm Damage Assessment
Scope: Conducted storm damage assessment in the wake of Category 4 Hurricane Ian
Location: Various locations in Southwestern Florida

On Sept. 28, 2022, Hurricane Ian made landfall near Cayo Costa in southwestern Florida as a dangerous, high-end Category 4 storm. The storm’s catastrophic winds, storm surge, flooding and tornadoes caused extensive damage. 

Irby Construction was ready with teams on the ground consisting of more than 60 personnel. Irby conducted damage assessment in impacted areas throughout Southwestern Florida including collecting data and necessary requirements for reporting, riding out circuits and marking maps where poles, wire, and equipment were down. 

As a result of Irby’s storm damage assessments, the company and its customers were able to assign the right crews and right equipment to the right place so that power could be restored as quickly as possible.

ENTERGY HARAHAN-AVONDALE 230kV RIVER CROSSING TRANSMISSION LINE

Type: Transmission
Scope: Water Crossing, Emergency Restoration
Location: New Orleans, Louisiana
Client: Entergy New Orleans

Entergy New Orleans provides electricity to more than 209,000 customers in Orleans Parish, Louisiana. On Sunday, August 29, 2021, Hurricane Ida made landfall as a Category 4 hurricane with sustained winds of 150 mph. The New Orleans area suffered damage causing outages for approximately 895,000 customers.

As a result of Hurricane Ida, a 475-foot lattice transmission tower in Avondale, a suburb on the west bank of the Mississippi River, was damaged and fell with conductor lines landing in the river. The tower on the Harahan side of the river remained intact with the conductor lines attached. This was a primary circuit for New Orleans and power was rerouted to restore electricity for customers until the damage could be repaired.

Entergy New Orleans contracted with Irby to manage the project from beginning to end. The removal of the destroyed transmission tower’s lines in the Mississippi River was a national priority. Efforts included coordinating with the Army Corps of Engineers, U.S. Coast Guard, Levee District, Louisiana State Police, Jefferson Parish EOC, the Governor’s Office of Homeland Security and other agencies to ensure safety and minimize risks.   

To safely remove the wire from the tower, clearing the downed conductor lines was completed by Dem-Tech through a series of controlled detonations. Explosives were attached to the conductor lines on both sides of the tower and demoed in sections. 

Once the lines and old towers were cleared away, Boh Bros. Construction Co., LLC, completed pile driving work and Irby sister company Legend Foundation Services installed anchor bolted piers to resist uplift forces that might otherwise cause the new tower and lines to be extracted from the ground.

With foundations in place, Irby, TNT Crane, and A&J Steel erected two 475-foot PyraMAX towers to supersede the old ones. With only 6 hours a day permitted by authorities to shut down major river traffic, Irby has begun stringing the lines using barges across the 3,700-foot span of the Mississippi. Once that is complete, energizing the lines is the last step in bringing this major transmission system back to life.

Irby is proud to have been recognized by our client, Entergy, for our work on this project as a Premier Vendor for Customer Centricity. Watch the Premier Vendor Award video here.

Type: Emergency Restoration
Scope: Performed emergency power restoration services throughout the Gulf Coast in the wake of Hurricane Harvey.
Location: Gulf Coast, USA

Hurricane Harvey was a category 4 storm which made landfall on the United States Gulf Coast in August 2017. The storm caused substantial damage including electricity outages resulting from high winds and significant flooding.

At its peak, forced outages displaced more than 10,000 MW of electricity generating capacity within the Electric Reliability Council of Texas grid including six major 345kV transmission lines and more than two hundred 69 kV–138 kV lines. As Harvey made landfall, caravans of Irby specialist personnel and equipment were mobilized so the power restoration process could begin as soon as the rain and winds subsided.

Alongside many fellow Quanta Services companies, Irby teams logged 114,000 manhours restoring power to impacted communities.

Start Date: August 2017
Completion Date: October 2017
