Our extensive services for
industrial large tank farms
We understand that operating and maintaining your bulk tank farms implies several challenges. Downtime due to new construction or decommissioning, the complexity and demands of operations, and regulatory compliance require extensive expertise and careful planning.
This is exactly where we assist and offer customized solutions and optimization for your facilities. We are your competent partner for extensive services around industrial bulk tank farms and chemical parks.
Overview of our services
From degassing via our partner company SIS GmbH, to cleaning of tank facilities and concept development and leakage systems monitoring, we offer a wide range of services to optimize and protect your facilities. Through years of experience and innovative products, we not only reduce the downtime of your equipment, but also extend the life of your tank farms and protect people and the environment from risks.

SOYK GmbH has special cleaning robots including the associated control unit and suction trolley. In terms of occupational safety, an important advantage is that no personnel is needed inside the tank during rough cleaning (driving). Via an installed scaffold ramp, the cleaning robot is inserted into the tank via manhole (NW 600). The robot with his camera is guided and driven through the tank via monitor with the aid of a joystick. The operators observe and control the robot via monitor from inside the control container. The robot is connected via a suction line to a suction truck, which transports the removed product to the disposal site.
Services provided under the general contractor concept
- Creation of a cleaning concept tailored to the specific case for the internal approval process and for submission to the relevant regulatory authority.
- Creation of the complete construction site setup/work preparation.
- Provision of the necessary cranes.
- Provision of construction power via generators.
- Setup and operation of the decanter system.
- Sampling and disposal management of decanter sludge
- Complete QHSE management
- Preparation of all work permits for the project for all trades
- Coordination of the necessary scaffolding work (scaffolding tower on the tank roof)
- Coordination of the operation of the combustion chamber (setup, connection, TÜV approval, subsequent operation of the combustion chamber)
Benefits for the operator
In summary, using the process described in SOYK’s cleaning concept offers the following advantages:
- Only one contact person for tank cleaning in the general contractor concept, resulting in considerable time savings for the wastewater treatment department
- Significant time savings through coordination of the individual trades, resulting in shorter tank downtimes
- Reduction of emissions from the tank cleaning process to a minimum through the use of a combustion chamber from ETS Degassing GmbH (emissions protection).
- No odors due to the combustion chamber insert
- First-time use of a mobile A-1 decanter system in combination with a mobile combustion chamber system, thereby improving emission protection and occupational safety






SOYK GmbH is a management contractor. This includes expert opinions in case of accidents or oil spills, where an assessment of the subject of protection, soil, and groundwater, is required. Our goal is to offer tailor-made solutions and, in the event of damage, to competently assist you in securing or remediating soil and groundwater contamination in coordination with the responsible regulatory agencies.
Expert services for environmental remediation
Our experienced team is specialized in the expert assessment of soil and groundwater damages caused by product leaks of substances hazardous to water. We possess comprehensive expertise and experience to conduct risk assessments and remediation investigations for soil and groundwater. Based on the results, we develop customized remediation concepts and plans in accordance with the requirements of the Federal Soil Protection and Contaminated Sites Ordinance (German BBodSchV).
Our range of services includes the planning and control of hydraulic securing measures as well as excavation measures for contaminated soils. In addition, we prepare groundwater monitoring concepts and implement soil remediation measures. During the implementation of remediation measures, we offer expert support and monitoring to ensure that all required standards are met. In addition, we carry out remediation success controls to verify the effectiveness of the implemented measures for the responsible regulatory agencies.

Environmentally sound degassing of crude oil tanks and tank farms is of great importance to ensure the protection of the environment, residents and employees. At SOYK GmbH, we rely on advanced degassing technologies to effectively reduce harmful gaseous emissions in a proven and controlled manner. With this we minimize potential environmental impacts and help create a safe, emission- and odour-free environment.
Another important aspect of environmentally sound degassing is the prevention of explosive atmospheres. SIS degassing methods ensure that these gases are removed and with this eliminate the risk of ignition. This protects employees from potential hazards and ensures the safety of the entire plant.
