Start-up challenge: Inspecting and cleaning of large pipes
PIPEYE: the remotely operated underwater vehicle to improve pipeline cleaning at thermal power plants
The Spanish company SubSea Mechatronics (SSM) has developed an underwater ROV (Remotely Operated Vehicle) called PIPEYE that will allow Iberdrola's team to inspect and clean the large pipelines of our power plants, under the highest quality and safety standards.
Winning start-up
SubSea Mechatronics (SSM) has been selected in the PERSEO Start-up Challenge: Inspection and cleaning of large pipelines, a challenge that sought new solutions and technologies to help clean the large pipelines of thermal power plants, favouring their sustainability.
The company has developed an underwater ROV (Remotely Operated Vehicle) called PIPEYE that will allow Iberdrola's team to inspect and clean the large pipelines of our power plants, under the highest standards of quality and safety. This equipment replaces the traditional way of carrying out these operations, which to date have been carried out by divers, with the limitations that this entails. The use of PIPEYE will make it possible to inspect and clean a larger section of pipe, as well as to gather new data related to the state of the infrastructure and the amount of accumulated waste that must be extracted for the correct operation of the installation.
Context
Iberdrola group is present in more than 40 countries, including Spain, the United Kingdom, the United States, Brazil, Mexico, and Australia, where the company has generation, network and energy retail operations.
Within the group, the Generation area focuses on energy protection by building, operating and maintaining thermal power plants, and purchasing and selling the energy on the wholesale markets.
Iberdrola has more than 12 GW of installed capacity in this type of power plant, mainly in Spain and Mexico. In light of Iberdrola's commitment to sustainability and respect for the environment, it is searching for and implementing new solutions and technologies to improve the sustainability of these assets.
One basic hallmark of this type of power plant is that their refrigeration circuits use water, which in most cases consists of recirculating water from natural sources such as rivers, seas and oceans. The plant maintenance tasks include the inspection and cleaning of the large pipes through which the water flows around the plant.
Sometimes, these large pipes carrying fresh or saltwater, which can be hundreds of metres long and between one and four metres in diameter, require periodic inspections. Furthermore, they can be made of several types of material, although generally they are manufactured in steel or glass fibre.
If, during the inspection, the pipe walls are found to be dirty, usually with organic material, they must be cleaned to prevent blockages that may reduce performance, lead to outages in the plant or harm the environment, by interfering, for example, with the thermal gap between the inlet and outlet water.
Challenge description
This is the context in which Iberdrola — through its PERSEO International Startup Programme — has launched a new challenge to find innovative solutions for inspecting and cleaning large water supply pipes in electricity power plants.
The innovative solutions sought have two objectives:
On the one hand, be able to perform underwater inspections more efficiently while the system is operating, or at least maximise the availability of the system. For the inspections, the aim is:
a) To gain comprehensive information about the depth of deposits in specific areas along the pipeline
b) Estimate the amount of dirt adhered to the pipes
c) Know what type of dirt this is: tubularia, sludge, mussels, etc.
On the other hand, solutions for cleaning the pipe as efficiently as possible, including the several tonnes of accumulated dirt.
Among others, the following value propositions will be considered, which will be analysed by the Generation team at Iberdrola:
- The maturity and reliability of the solution
- Ease of installation and operation
- Cost of investment and operation
- Scalability of the solution for this and other applications in power plants, such as hydraulic and nuclear facilities
- Improvements to safety at work
- The solutions must be environmentally friendly
- Possible processing and recovery of the waste obtained
It will also be considered whether the solutions:
Ensure safety during the inspection and cleaning process
Optimise the cost and duration of current operations
Maximise the continuity and availability of the system during inspection and cleaning operations
The prize
The prize will consist of a collaboration and test agreement with PERSEO or any other group company, which will support the cost of those activities and provide the winner with all the necessary technical support, as well as a site and real data to test the solution, giving access to equipment, teams, infrastructure, high technology sites and shared work areas. The project will be undertaken in collaboration with technical specialists from the Iberdrola Generation area.
If the assay or test of the concept is satisfactory, Iberdrola may offer the winner the opportunity to scale up the solution adapting it by means of commercial agreements.
What's more, PERSEO will consider investing in the participating company and/or the winner of the challenge.
