Our commitment to quality goes far beyond the research & design, engineering and manufacturing processes and the sale of a plant marks only a midway point for us. From there on, we make sure that our clients have all the backup they need to operate their HAMANN plant during its entire lifespan. We do so with our highly qualified and experienced staff at HAMANN headquarters near Hamburg, Germany and with our global network of over 40 sales agents and service partners.

Our team of service engineers includes those who have undergone BOSIET (Basic Offshore Safety Induction and Emergency Training) and HUET (Helicopter Underwater Escape Training) trainings and are therefore qualified to work on offshore platforms and installations.

We take pride in our reputation for offering excellent technical support to our clients.

To get your new HAMANN marine sewage treatment plant set-up and running perfectly from day one, we recommend having one of our qualified and experienced HAMANN service engineers to do the commissioning on board. He will make all the settings based on your specific situation on board and give your crew an overview of the few simple steps to operate the plant correctly.



HAMANN marine sewage treatment plants are extremely easy to operate. However, we recommend training the crew in the correct handling of the system installed on board. A trained crew will be able to solve most malfunctions and problems without the need for a HAMANN service engineer on board. If you are interested in having your crew trained by HAMANN, we will be happy to give you a quote. A training programme will be designed for your specific needs taking into account the qualification and experience of your crew. The training will be held directly on board your vessel on the specific plant to be operated.



Having your HAMANN marine sewage treatment plant inspected by a qualified HAMANN service engineer on a regular basis pays out in the long run. During an inspection, the system status and the condition of all critical components and wearing parts will be checked. Potential sources of malfunction can be detected and dealt with before they generate a major problem. System software can be updated and settings can be adjusted if needed.



HAMANN marine sewage treatment plants have an established reputation for being extremely reliable. Nevertheless, problems can occur and if they do, we are there for you. Whatever the problem is and wherever you are, you will get prompt and qualified support either through a HAMANN certified service station close to you or through HAMANN AG direct. Please contact us by whatever means suits you. Our qualified and experienced HAMANN service engineers will assess the problem based on your description and suggest a feasible way to solve it.



If your HAMANN plant has been in service for a long time or is in a bad overall condition, you may consider having your plant refurbished. A refurbishment includes the cleaning of the plant, the exchange of worn out parts and the upgrade of outdated components. After reassembly your HAMANN plant is once again in immaculate condition.



We attach great importance to easy and uncomplicated operation of our systems in daily operation on board. With our maintenance packages, we offer our customers a convenient solution for maintenance and servicing. Based on your specific needs, we put together a package with which you have covered all eventualities in the best possible way.
