Structural Optimization and Simulation of Electric Power Transmission Towers

Sponsor: Luciano Oliveira

Leaders: Guilherme Mendonça e Marcos Izumida

How can we ensure the automatic and offline verification of Occupational Health and Safety (OHS) compliance for outsourced and subcontracted professionals in the field, reducing risks and increasing inspection efficiency?

Climate change has led to an increase in the frequency and intensity of extreme winds and severe storms, creating growing structural risks for power transmission lines. Towers designed based on historical conditions no longer adequately represent the new climate regime, increasing the likelihood of overloads, unexpected failures, and even cascading collapse following conductor rupture. This new reality demands advanced solutions capable of predicting the structural behavior of towers under increasingly extreme climate scenarios, ensuring greater resilience, safety, and operational continuity. 

We seek partners to develop, in collaboration with a university that holds the research model, an advanced engineering software for the optimization of transmission tower designs, ensuring optimal design for the manufacturing and assembly of the complete family of towers. The solution must also ensure resistance to the climatic conditions of the installation region, considering collapse simulations, reliability assessment, and dynamic analysis of complete sections of power transmission lines.  

The development will be carried out jointly with AXIA Energia and a university. The former will provide the development environment and practices, while the latter brings technical expertise and domain knowledge in the subject matter.

Companies may participate in this challenge provided that they cumulatively meet the following requirements: 

a) Be a software compay with proven experience in engineering projects, preferably in structural, civil, mechanical, or electromechanical environments; 

b) Have operations or a working structure in a time zone compatible with Brazil, in order to ensure continuous interaction with the involved teams; 

c) Demonstrate the capability and availability to work jointly with a university in an applied research and technological development environment; 

d) Expressly agree to the model of full assignment of the product’s intellectual property to AXIA Energia; 

e) Have a qualified technical team with proven capability to develop mission-critical engineering solutions. 


Technical Evaluation Criteria:

The proposals will be evaluated considering, among other aspects, the following technical criteria:

a) Technical Experience

  • Track record in the development of engineering software;
  • Previous projects involving modeling, structural simulation, or advanced analyses
  • Experience with mission-critical applications.

b) Modeling and Simulation Capabilities

  • Knowledge of finite element methods (FEM);

The following will also be considered:

  • Organizational maturity and the ability to execute medium- and long-term projects;
  • Complex project management structure;
  • Availability of a dedicated team;
  • Ability to meet jointly established schedules and technical milestones.


STRATEGIC CRITERIA (DESIRABLE) 

The following will be considered as differentiators, although not mandatory: 

  • Use of advanced computational optimization techniques; 
  • Long-term vision for the evolution of the software as a reference product in the sector; 
  • Company headquartered in Brazil’s North, Northeast, or Central-West regions. 

Deadline: Proposal submission form will be available until 31/03/2026.
