To meet these demands, we employ highly skilled personnel and top quality machines.

Without our employees, their know-how and commitment, Wulf Johannsen would not be the same.

Therefore we set a high value on extensive and coninuous training.

Quality and Training

The certifications and approvals received are awards and challenges at the same time: they require the continuous implementation of the set requirements in daily work. This includes the continuous renewal and monitoring of our high-quality production and machining equipment as well as the tools we use.

The most important backbone of our business are our qualified and committed employees. In order to comprehensively deal with the questions of our customers, we train our employees to meet the requirements to a very high degree. This includes that many of our employees receive a double qualification as mechanical and electrical service specialists. As a manufacturer-independent service provider, we also qualify our employees for machining engines of different brands and types. In this way, we are already much more capable of finding solutions than many of our competitors in the service business.

In order to maintain and secure this high level in the long term and to familiarise new employees with our quality standards, all employees regularly take part in our internal training and education program. This includes training on the basic topics of safety and environmental protection, practice training and testing for high-quality and reproducible work, as well as tutorials to familiarise employees with new technologies and engine types.

We are pleased to receive feedback from our employees that working at Wulf Johannsen is particularly satisfying and varied - and we are pleased to note that our employees are staying with us for the long term. In this way, we also fulfil one of our fundamental corporate principles, which states that we value and promote our employees as an essential pillar of our business.
