Your Professional Partner for Technical and Nautical Supply

Founded in 1983, the Ing.-Buero Querin GmbH has established itself as a reliable partner for the supply, installation, repair, and maintenance of communication and navigation equipment for the commercial shipping industry worldwide.

With our 24/7 service support we arrange and coordinate service attendances on a daily basis. Because of their high level of skill, our technicians are used by our customers around the globe.

In addition to our own technicians, we have an extensive network of qualified service partners in the marine industry. Based on years of experience with these partners, we are able to ensure the same service quality that we do expect as our standard.

Our longtime experience, our expertise, our continuous strive for perfection, as well as our customer oriented flexibility and dependability have made the Ing.-Buero Querin GmbH a well-known partner to mariners.

From our large stock of new equipment, as well as spare parts, consumables and supplies we are able to provide your fleet with the required products on very short notice.
