Creditreform awards us the CrefoZert creditworthiness certificate

he independent credit agency Creditreform has checked our company for creditworthiness and security and confirmed our excellent credit rating structure.

This seal, which only a few receive, stands for reliable business relationships and the highest solvency.

We are very proud of this positive assessment of the current situation and future prospects of our company.

Both the audited balance sheets and the personal interviews with the management showed that our company has met the high certification criteria.

Our customers and suppliers are very important to us. For this reason, we have taken the path of trustworthy certification. A solid foundation creates reliability.

Such an award is based on the joint high commitment of all employees of our company.

Therefore SDT stands especially also for job security on a high level and offers a high stability to all employees, but also to new applicants.

Let's talk about your next project:



10.09.2021 We have received the grant notification for the R&D project "Development of a compact gene set with CO2-neutral fuel"!

Application approved: Generator with CO2-neutral fuel

By February 2023, we will develop a generator set with all the necessary peripherals for power generation with CO2-neutral fuel.

The modular base frame of the genset will allow the storage of a methanol combustion engine or a methanol/hydrogen fuel cell. Due to the planned use of methanol or hydrogen, the genset will be encapsulated from the eventual engine room with a gas-tight acoustic enclosure.

This should simplify the integration of the gene set into the respective engine room and fulfill the necessary requirements with regard to gas safety. As with the other R&D projects in the network, this innovation aims to enable installation in smaller vessels up to 60 meters. We are supported in this by ABEKING & RASMUSSEN Schiffs- und Yachtwerft SE and Rolls Royce Power Systems GmbH.

The development of this exciting project was carried out in close cooperation with DSN Connecting Knowledge, to whom we would like to express our sincere thanks once again.

"Campfire" is one of the implementation projects of the lead project "TransHyDE" for the development of a hydrogen transport infrastructure, which is one of three lead projects of the Federal Ministry of Education and Research (BMBF) for the implementation of the national hydrogen strategy.

SDT is involved as a partner in the "Campfire" implementation project.

SDT is committed to green and CO2 reduced energy generation on ships as a partner of the implementation project "Campfire- Wind and Water to Ammonia - Maritime Fuel and Energy Storage for an Emission Free Future".


The objectives of this project include:

- the use of ammonia as an alternative fuel in shipping is one of the keys to reducing CO² emissions
- SDT has been pursuing the development of alternative and environmentally friendly propulsion and power generation solutions for ships in this and other R&D projects, such as "EcoShip60" for several years now


The protection and preservation of our environment is the task for the 21st century.

As SDT we face up to our responsibility.

The sea air massively counteracts the standing time at sea.

What do you have to pay attention to in any case for your existing installations at sea?

As you can see in this picture, we have made this generator fit for use at sea with a special, adapted filter that we have retrofitted.

This is how we optimize your diesel generator according to your needs.

With SDT you have a reliable and pro-active partner who always guarantees you the right quality in service and spare parts supply.

So that you can approach the next maintenance with a strong partner and always be optimally supplied.

In November 2020 we handed over 30 mobile emergency power supply units to the state of Schleswig-Holstein.

How does SDT in Schleswig-Holstein ensure the general power supply in case of a nationwide power failure?

In November 2020 we handed over 30 mobile emergency power supply units to the state of Schleswig-Holstein. The Ministry of the Interior made this investment in order to be able to compensate for a nationwide power failure.

The mobile 100kVA power generator has

- 4 cylinder IVECO engine

- Sound enclosure

- FIRECO lighting column

- max. mounting height 9 m

- 6 separate lighting elements 180,000 lumen

- Tandem axle trailer

- Tool cabinet

- 2.9 t total weight


The trailers will be used in the 15 counties and independent cities of Schleswig-Holstein. In the event of a power failure, the system can either be used to feed into the grid at a predefined point, in this case a filling station, or in island operation for conventional consumers.

We would like to take this opportunity to thank those responsible and all suppliers for the great cooperation.

General information for our customers and partners

Dear customers and partners, 25.03.2020

The situation created by the spread of the coronavirus (COVID-19) leads us to take profound and appropriate measures to ensure the protection of the health of our employees and all business partners with whom we have contact.  In view of these circumstances, we have imposed a number of internal restrictions and procedures with regard to recommendations published by the Robert Koch Institute, for example, which we would like to briefly inform you about below: 

A working group has been set up to monitor the activities related to COVID-19 according to the instructions of the Federal Government and other authorities, to continuously monitor the situation and to ensure that all SDT employees are kept informed at all times.

Instructions for the right behavior and habits have been posted in all areas of the company for the benefit and safety of all. Hygiene measures were taken and hand disinfection dispensers were installed.

Business trips of any kind were reduced to an absolute minimum or postponed to a future date.

External visits to SDT have been reduced to the absolute minimum. A detailed self-declaration is required for access to our facilities and premises. Meetings with customers/suppliers are only held when absolutely necessary to ensure that our work runs smoothly.

Appropriate measures have been taken to limit the timely presence of employees in the common areas. In addition to the use of home office workplaces, we have set up individual offices for each office staff member. 

Our employees are requested to avoid mass events and to respect the rules of social distance in public areas.

All employees have been advised not to come to work if they should have corresponding symptoms such as coughing and/or a cold and/or fever.
We have therefore taken some measures to slow down the spread of the virus. Please support us in this and make equivalent provisions for yourself and your team. We will continue to monitor the situation closely and make every effort to protect the safety of our employees and ensure the smooth running of our activities in the service of our customers.

If you have any questions and as a contact person in our company, Ms Petra Schubert ( schubert@sdt-kiel.de ) will be happy to help you.

With kind regards


Thomas Schwarke
