Project Management of an Emergency Ethylene Oxide Transfer System for a Major Chemical Industry Development
As part of the project management of an emergency ethylene oxide transfer system, we coordinated the delivery of a critical process-safety element for a major chemical industry investment in Hungary, from supporting the engineering design phase through to the successful completion of the Factory Acceptance Test and Site Acceptance Test.
The project required us to coordinate the challenges arising from the hazardous process medium, stringent process-safety requirements and a demanding schedule linked to plant start-up across the end user, our client and the contractor organisations.

From engineering design support through to successful completion of the Site Acceptance Test
Project Background
During a major chemical industry investment in Hungary, the volume of ethylene oxide used at the facility increased significantly. Ethylene oxide is a toxic, flammable and highly reactive substance. Its storage and transfer must therefore take place under stringent technical and process-safety requirements.
For this reason, an emergency hazardous-material transfer system must be available in the event of a road or rail transport incident, such as an accident involving a tank vehicle or rail tank car. The system enables ethylene oxide to be transferred from a damaged vessel into another intact vessel in a compliant and technically safe manner.
The availability of the system was therefore not an optional addition to the investment. It was one of the technical safety conditions required for commissioning the newly constructed plant, whose value amounted to several billion forints.
Our client was the company contracted by the end user to supply the emergency ethylene oxide transfer system. Chess Energy participated in the project as project manager.
Project Management of an Emergency Ethylene Oxide Transfer System – What Made the Assignment Complex?
The complexity of the project did not arise from a single technical issue, but from the combination of several factors.
Dual-Sided Responsibility
Properties of the Process Medium
Schedule Constraints
Coordination of Multiple Stakeholders
In situations of this kind, the client often does not have an available specialist who can oversee the entire project lifecycle. Chess Energy specialises in fulfilling precisely this role.
How Did We Contribute?
Project management of the emergency ethylene oxide transfer system covered the full duration of the project. We remained involved from the engineering design phase through manufacturing and assembly to the successful completion of the FAT, or Factory Acceptance Test, followed by the SAT, or Site Acceptance Test.
Chemical Industry Project Management and Technical Coordination
- Continuous monitoring of the project’s technical scope, schedule and milestones
- Coordination and communication between the end user, our client and the contractor organisations, supported by clearly defined responsibilities
- Coordination of engineering, manufacturing and assembly activities and management of interfaces between disciplines
- Monitoring of the manufacturing and assembly process and alignment between the technical scope and the project schedule
- Management of technical documentation and support for informed decision-making
- Change management and regular reporting on project status
- FAT and SAT coordination, including preparation and execution of the Factory Acceptance Test and Site Acceptance Test
Engineering Design Support
The equipment was not designed by Chess Energy, but we supported the engineering design process throughout the project. We relied on the professional expertise of the partner companies while carefully monitoring the engineering decisions and drawing on experience gained from previous projects.
Our objective was to ensure that the end user received equipment capable of reliable operation under the intended operating conditions.
The same approach was applied during the testing phase. The Factory Acceptance Test and Site Acceptance Test are not merely formalities. They are the two key stages at which any discrepancies between the intended and the delivered technical scope can still be identified and addressed.
The Outcome
Project management of the emergency ethylene oxide transfer system concluded with the successful completion of both the Factory Acceptance Test and the Site Acceptance Test. The equipment was handed over to the end user in accordance with the intended technical scope.
This fulfilled one of the technical safety conditions associated with plant start-up.
The project demonstrates that sound engineering content alone is not sufficient for a process-safety system.
Precise coordination between stakeholders, traceable decision-making and continuous professional involvement contribute to more predictable project delivery and help ensure that the client receives the technical scope that was originally specified.
