A partner to industrial companies for 30 years, our versatile team designs custom solutions and brings together all its areas of expertise to successfully carry out unit shutdowns at your industrial site. A unit shutdown is an essential planned interruption that makes it possible to check the condition of your equipment and carry out maintenance, modernization, extension, or cleaning work. With leading experts by your side, you can manage this large-scale project with the aim of returning equipment to service quickly and optimizing your production capacity.
Work planning:
We support you in the management of your unit shutdowns from the operational planning phase onward. By methodically optimizing work sequencing and managing potential simultaneous operations, we significantly reduce overall process downtime.
Dismantling and Reassembly of Equipment:
Our services for equipment dismantling and reassembly (columns, bundles, piping, pumps, etc.) are carried out using proven expertise, in full compliance with applicable safety standards and taking into account any residual pressure or energy within the equipment.
Removal and Handling Operations:
We perform removal and handling operations of all types and sizes, with preservation of installations and equipment as a priority. Designed in close cooperation with our clients, each service is tailored to your specific needs, delivered within agreed cost and schedule constraints, and includes all required testing and inspections.
Restart Assistance:
We provide support and assistance during the inspection and control phases prior to restart of your installations, ensuring optimal conditions for safe and efficient return to service.
The Ortec Group has know-how and proficiency in a broad variety of techniques to offer custom industrial cleaning solutions.

Hydrodynamic cleaning from 150 to 2500 bar:
Recognized as an efficient and environmentally friendly process, we provide customized manual or mechanized cleaning solutions adapted to all types of fouling at your industrial site:

Using cold as a cleaning agent, cryogenic cleaning enables our teams to effectively treat all types of equipment and difficult surfaces.
Low-Pressure Abrasive Blasting:
For our parts cleaning, surface refurbishment and descaling operations, we use low-pressure abrasive blasting. This low-pressure surface treatment is more environmentally friendly and provides an alternative to chemical stripping. This technique can be used on metal, wood, stone, and plastic surfaces.
Pumping, Cleaning, and Degreasing of Vessels:
Our pumping, cleaning, and degreasing services are carried out using the most effective and innovative techniques, including industrial vacuum units, hydrocleaning equipment, and hydrodynamic and mechanized methods, to ensure the long-term reliability of your installations.

Removing a fuel oil tank is a mandatory when you want to change or upgrade your heating system. Our teams support you throughout this process: from advice through removal of the fuel oil tank.
Due to the nature of the products contained in the tank (fuel oil, deposits/sludge, gas), this operation must be carried out by trained and qualified professionals in order to manage all risks to people, property, and the environment.
Several sensitive operations are required before your tank can be removed:
- Draining, degassing, and cleaning
- Neutralization
- Dismantling and removal
- Waste management
- Certificate of compliance

Ortec’s local teams carry out all of these operations while managing risks and complying with regulations.
