Fuel flexibility is the future of the maritime industry LAST YEAR, ADS VAN STIGT CELEBRATED ITS FIFTIETH ANNIVERSARY. OVER THE YEARS, THE COMPANY HAS GROWN INTO A STRONG SALES AND SERVICE ORGANISATION THAT HAS DEVELOPED FROM REPRESENTATIVE OF FOREIGN MANUFACTURING COMPANIES TO AN INDEPENDENT IMPORTER, distributor, and maintenance expert.

DS van STIGT became the A-specialist for reverse reduction gearboxes, planetary gearboxes, clutch reduction and conventional gearboxes, controllable pitch propellers, flexible couplings, and electronic control and monitoring systems. As complete propulsion packages can be supplied, system responsibility is accepted by the company. In short, ADS van STIGT is the name of a nationally and internationally operating company offering maritime knowledge, an extensive state-of-the-art programme and a large warehouse with thousands of final products and parts, supported by efficiently equipped workshops, and a 24/7 service organisation. Together, they guarantee an optimal care for
each product once it has started its long operating life after it has been put into service.
Sustainability
Recently, the enterprise has seen that the interest in hybrid and electric propulsion is starting to get serious in the market and that all its customers within the shipbuilding industry are focused on sustainability. Not only for the company, but for all suppliers that are part of the powertrain on board of a vessel, it is very important to grow and to be able to deliver according to customer’s demand. This is why ADS van STIGT emphasises on expanding the package that they deliver on board.
Hybrid propulsion optimises the fuel efficiency of vessels that have a flexible power demand such as fishing vessels and tugs. The combination of mechanical power from diesel engines and electrical power from electric motors guarantees the vessels a broad operational capability. The electric power source can consist of what is available today, but it can also be a source currently in development and available in the coming years, and is thus flexible. Some recent innovative projects that ADS van STIGT has collaborated on are: New push boats for Thyssenkrupp Steel Europe Push boats Thyssen I and Thyssen II of Thyssenkrupp Steel Europe needed to be replaced after fifty years of service. The steel company is therefore purchasing two new units. The vessels are built by Barkmeijer Shipyards. Voith supplied two Voith Schneider Propellers that are driven via a Katsa reduction gearbox type L700 and a Geislinger Gesilco shaftline in combination with a Carbotorq coupling with the 780kW electric motor. The new push boats are based on a modified design and the modern propulsion will be a lot more efficient.
Delivery by ADS van STIGT per push boat: • 2x Katsa gear box reduction type L700 – Ratio: 3,19:1 – suitable for 800kW at 1,800rpm • 2x Geislinger Gesilco shaftline + Carbotorq coupling Katsa reduction gearbox type L700
