Since its establishment in 1984, TTTBV has been providing service to the products and installations it sells, both on board and in its own workshop. Commissioning, repairs and inspections take place almost daily on board ships. Although the focus of the work area is on Northern Europe, service jobs are also regularly carried out worldwide. In addition to advice, calculation work, delivery and project management, you can also go to Theunissen Technical Trading for commissioning and repair of the following product groups:
In addition to repairs, TTTBV carries out complete conversion projects. It is thus possible, after having discussed the wishes and possibilities in advance, to exchange the entire internal telephone system in one day. Other systems, such as a fire alarm system, searchlights or windscreen wipers, can also be exchanged entirely on board under certain conditions.
