Schottel Hydro

What Schottel Hydro does

SCHOTTEL GmbH, headquartered in Spay, Germany and wholly-owned by SCHOTTEL Industries GmbH, is a privately-held maritime propulsion system manufacturer founded in 1921. The company designs, develops, and manufactures azimuth propulsion systems, controllable-pitch propellers, transverse and rim thrusters, pump jets, and integrated automation and propulsion control systems under brand families including SRP, SRE, STP, SCP, SRP-R, SPJ, STT, SRT, SAS, and SMS. Its power range spans 50 to 30,000 kilowatts across more than nine product series, with the original 360-degree steerable RudderPropeller (invented 1950 by Josef Becker) as its signature technology and over 17,000 units installed globally. Manufacturing is conducted at two German production sites: Dörth (24,000 m², opened 2015) and Wismar (15,000 m², acquired 1999), with the latter focused on large controllable-pitch propellers up to 30 MW and 8-metre diameters.

The company sells through a direct enterprise field-sales model supported by 17+ wholly-owned subsidiaries and authorized service stations across six continents, targeting shipbuilders, shipowners, and vessel operators across ten vertical segments including tugboats/workboats, ferries, tankers, cruise ships, offshore wind service vessels, naval/governmental, research, yachts, inland waterway, and dredging vessels. Revenue is generated via (1) hardware sales of custom, quote-based propulsion systems on multi-year contracts tied to vessel specifications, (2) after-sales services comprising spare parts, preventive maintenance, technical consultation, 24/7 emergency hotline support, and training, and (3) a retrofits and conversions line extending the operating life of existing vessels. Recent contract wins (2024-2026) demonstrate positioning around the maritime energy transition: dual-fuel methanol tugs for Kotug Canada (Sanmar Shipyards), hybrid chemical tankers for Mureloil achieving up to 50% GHG reduction, two LNG bunker vessels for Shanghai International Port Group, 40 RudderPropellers across 20 escort tugs for ONEX Shipyards, and a hybrid electric hydrographic vessel for the UK Northern Lighthouse Board.

Underlying engineering capability rests on more than 100 engineers across hydrodynamics, mechanical R&D, automation and propulsion control, and technical product information, backed by a 900+ core CFD cluster, annual 500+ propeller designs, 100+ FEM simulations, 30+ component tests, and 20+ prototype factory acceptance tests. SCHOTTEL holds DNV-certified ISO 9001, ISO 14001, ISO 45001, and ISO 50001 management systems, AEO customs certification, and operates MariNet as a digital marine services platform. Research alliances with TUHH, SINTEF Ocean, Lürssen, NATO STO, Transport Canada's Quiet Vessel Initiative, and the BMWK-funded FlettnerFLEET consortium extend its R&D pipeline into propeller noise reduction, autonomous operations, and wind-assisted propulsion.
