We monitor the actual situation regularly and continuously and execute the necessary corrective actions that lead to an interference-free operation of your primary and secondary system that secure your power supply. Thus, expensive outages and losses can be avoided.

Our portfolio comprises tests that are an integral part of periodic inspections required by various institutions and manufacturers. We work on the basis of national and international standards, guidelines and regulations to suit the needs of the customer and to ensure that the operation of your system is secured.

Within the framework of the inspection process, root causes are analysed and consequences, which comprise possible solutions in case of deviations from the desired state, are presented with the objective of providing the customer with options for problem solving.

Periodic inspection

Periodic inspections are required by the licensing authority for offshore projects. OIS is in position to inspect the supporting structures, welds and scour protection. The inspection of the wiring of the inner park is also part of our scope of services. We are able to conduct these tasks when required with divers or where possible, ROV technology.

Complete solutions

In recent years, OIS Offshore Industrie Service GmbH and its affiliated companies have been involved in the construction of various offshore wind projects. This has enabled us to acquire a huge amount of expertise and to gain extensive experience in the installation and commissioning of various systems, equipment and components.

Our own maintenance staff has been intensively trained to provide our customers with this expertise - even offshore. Thus, they have all the necessary qualifications to execute safe, adequate and effective tasks.

Thus, OIS is able to offer comprehensive planning, coordination, maintenance, certification and periodic inspection solutions for the maintenance of offshore wind farms and converter platforms with its own personnel as well as in collaboration with affiliated companies. These solutions comprise the following areas: steel, corrosion protection, electrical (low-voltage, medium voltage, high voltage), radio, navigation and communications equipment, auxiliaries and auxiliary systems, underwater works, working with rope access (FISAT), transportation and logistics and spare part supply and management.

Maintenance / service

Maintenance of various systems is the cornerstone of any service program. No matter what strategy one uses, adaptations and repairs must be carried out, wearing parts replaced or parts modified. The objective of these maintenance tasks is to contribute to the long-term operation of the system and secure its performance.

We offer cost-effective and reliable solutions for your maintenance program. However, manufacturer-specific maintenance tasks are often subject to approval or training by the manufacturer.
