Who we are


In 2001, I founded MOH Service with the aim to provide professional installation and maintenance services to the petrochemical industry in the Rotterdam region. In the meantime, we have grown substantially and also have become active in the food industry and the offshore sector. Instead of regionally, we now work internationally.

Central unifying factor between the different markets is our specialty to make great components, structures and piping systems in both carbon steel and stainless steel. Quality and flexibility are our spearheads in this respect. Our 24/7 call out service is particularly popular with our customers. They call and we jump in the car to solve problems! Our workshop is open 24 hours a day. New components that need to be tailor made, we can often manufacture and install the same day!

Apart from the urgent matters that run through our call out service, we also carry out structural maintenance on the process installations of our customers through maintenance contracts or scheduled shutdowns.
Despite our growth, we have remained a family business in terms of culture. True team spirit reigns with us!
The job is carried out together; during the day, at night or on weekends, it does not matter.


Our aim is satisfied customers. And once a customer of MOH Service, is actually always a customer! Because of our flat organisation, we have little overhead and are very competitive in our pricing. Furthermore, we hold all qualifications that customers require such as ISO 9001, ISO 14001, ISO 3834, VCA ** etc.
Safety is a key priority in our operations. All employees are VCA ** certified. Next to this, our site superintendents and foremen follow additional training in safety leadership and safety awareness. Accident- and incident-free; that’s our goal.
