SUDOSERVICE was founded 25 years ago and is now under second-generation management.

The company’s success story began in 1988 when engineer André Jeznach, following a long and successful career in the marine equipment industry, decided to found his own company. One year later, SUDOSERVICE was born.

Initially housed in the Überseezentrum logistics centre at the Hamburger Freihafen docks, the firm originally specialised in providing replacement parts for Eastern European shipping companies (hence its name – ‘sudo’ is Russian for ship).

From o-rings to complete main engines, SUDOSERVICE supplied a complete range of ship equipment. The fall of the Soviet Union in 1991, and the resulting liberalisation of Eastern European markets, allowed the company to expand.

In 1997, SUDOSERVICE extended its range to include steel. Since then, it has been supplying shipbuilding steel, pipes, angled pipes and fittings to harbours and repair companies.

Today our customer base is no longer limited to Eastern Europe. Shipowners, ship managers, ports and companies from all around the world choose SUDOSERVICE as a reliable and expert partner.

The task of supplying replacement parts throws up new challenges every day. By 1998 the company had outgrown its offices and storage areas at the Überseezentrum – so André Jeznach decided to build a new head office with a high-bay warehouse. Just in time for the new century, SUDOSERVICE moved into its new premises.

Since then the company has been providing standard parts for a wide range of ship engines, from shafts and bearings, to pistons, cylinder heads, and seals.

In 2013, business studies graduate Mark Jeznach, son of the company’s founder, joined SUDOSERVICE, which then became a publicly limited company.

Since 2016 we are authorizied sales partner for Wärtsilä Seals and Bearings. This includes the brands Deep Sea Seal (DSS), John Crane Lips, Cedervall and JMT.

Since 2017 we are authorizied sales and service partner for Baudouin Engines.


The company currently comprises five people:

André Jeznach (consultant)
Mark Jeznach (managing director + consultant + Wärtsilä Seals and Bearings sales director)
Katrin Schoer (accountant)
Armin Setzke (consultant + engine replacement parts sales director)
Hans-Ulrich Krohn (sales representative)
