The Enel Group is looking for proposals around the best available solutions to improve health checks of poles and supports. In partnership with Enel Grids, your reliable, quantitative and objective measurement approach will benefit operator safety and network management. Do you have a solution, technology, or method for an objective and fast health check?
This is an electronic Request-for-Partners (eRFP) Challenge; the Solver is invited to submit a written proposal to be evaluated by Enel Grids with the goal of establishing a collaborative partnership.
As part of ongoing health and safety initiatives across the Group, Enel Grids is searching for a solution that can provide an objective and fast health check of a pole/support, to be added to the current visual inspection.
Current practices are often subjective, depending on tester’s experience and sensibility. Providing operators on the ground with a fast, easy-to-use, and universal understanding of relevant and objective information will support the assessment of the pole/support condition and therefore if this is suitable for operator climbing and, more generally, for network service.
Enel Grids is therefore looking for proposals around the best available solutions to improve health checks of poles and supports. In partnership with Enel Grids, your reliable, quantitative and objective measurement approach will benefit operator safety and network management.
When working at height in any industry, safety regulations and requirements must be followed. We need to ensure any equipment used or support climbed must be verified to be safe before climbing. According to Enel Grids standards on work at height, when operators are working on a pole or support, it is critical to determine its condition before an operator climbs it.
Poles that are unsuitable for climbing operations are also unsuitable for network service. The network maintenance plan, in particular the periodic inspections, provides for the reporting of unsuitable poles/supports on which their replacement or stabilization must be planned. Adding to the routine visual checks and testing, Enel Grids is seeking innovative solutions to perform reliable, objective and quantitative health checks of these poles and supports.
Before starting any activity at height, pole and support integrity (presence of damage, buckling, corrosion etc), mechanical requirement and stability have to be verified on site – in order to assess that it may sustain the stresses from the work. These stresses, including operator weight, equipment and tool weight for use or installation, and other working stresses (e.g. removal or tensioning of conductors), may lead to the failure of a defective pole/support or one not designed to handle these stresses.
- Wood poles usually fail by breaking at the point of their penetration in the ground – often due to internal rotting that weakens the material. For these wood poles, the focus would be more on the pole integrity than the methods of stabilization, e.g. ground consistency, considering these poles usually have not a foundation block.
- However, for reinforced concrete or metallic poles, they tend to fail due to an ineffective stabilizing effect. This happens when the pole is at the incorrect penetration depth, or when this depth reduces over time.
Enel Grids is searching for proposals that offer a solution that can provide an objective and fast health check of a pole/support, to be added to the current visual inspection.
Current practices are qualitative and subjective, depending on tester experience and sensibility. Your reliable, quantitative and objective measurement will help keep operators safe and improve network management.
This test and health check must be non-invasive, and could be based on diagnostic technologies of any kind. The scope of innovation in your solution and its universal potential is important – your solution could use physical, mechanical, thermographic, ultrasonic, magnetoscopic, hygrometric diagnostics, a combined approach, or any other relevant and successful.
The inspection approach and its conditions change dependent on the type of pole/support, their material, and then on their specific dynamics of failure. This also will have to take into account other factors: presence/absence of a foundation block, depth of penetration into the ground, the type of soil itself.
Ideally, your proposed solution will also allow for the recording and reporting of data, and including a connection to a database. This will help prepare for future health checks and provide more opportunity for future analysis and program work.
In general, the solution needs to satisfy the following must-have requirements:
- Effectiveness of checking the health of pole/support whenever this is required;
- Not impair the pole/support integrity, stability, or create other/further risk situations;
- Be easy and fast to be deployed or installed on the pole/support, and also non-invasive;
- Be universal as far as possible, i.e. flexible to use on poles/supports of different materials, sizes, kind; solutions for only one type of material will also be considered;
- Easily transportable by users and company fleet;
- Be user-friendly in order for users to take a quick decision;
- Require minimum maintenance;
- Be easy to implement, both in time and distribution;
- Be compliant with current normative of the countries of the Enel group or be possible to adapt to local normative with a limited effort.
- Be able to record the check results for reporting purposes, and also allow remote recording in a database.
