Energy Efficiency

Ecological Sustainability

Industrial production and administration facilities require energy. In order to limit energy consumption at the SCHOTTEL sites in Spay, Dörth and Wismar, all Germany, to absolutely essential levels and to monitor this, SCHOTTEL has been undergoing an energy audit in accordance with DIN EN 16247 and its own energy-saving measures. The objectives are to develop measures for the highest possible energy recovery and to feed recovered energy into other production processes.

PRODUCTION HALL LIGHTING CONTROL
  • Control of the light output of lighting depending on the amount of daylight; when there is sufficient light from outside, the lighting is dimmed or switched off
LARGE-SCALE PHOTOVOLTAIC SYSTEM
  • 2800 photovoltaic modules and 29 inverters at the Dörth production site generate a maximum output of 700 kW
  • Annual generation capacity of approx. 700,000 kWh covers 16% of energy required
ECO-FRIENDLY VENTILATION AND HEATING
  • Fresh air and heat supply through diffusers close to the workplace
  • Rotary heat exchangers support the heating of the production hall through heat recovery
  • Recirculation of the heat energy released by compressors to the production process
RAINWATER UTILIZATION
  • Two 500m³ cisterns for water supply to the water basins in the test stand facility and for fire fighting
HEAT RECOVERY FROM TEST STAND WATER BASINS
  • Test runs of the propulsion units in the test stand water basin generate thermal energy from electrical energy, which leads to the heating of the water in the test basin – a heat pump extracts this heat from the water and feeds it into the office building for heating purposes
DISPOSAL: AVOIDANCE/REDUCTION/RECYCLING
  • Avoiding waste through optimized processes
    e.g. optimized component geometries lead to less machining waste and reduced transport and packaging requirements
  • Emission reduction through state-of-the-art production facilities 
  • Waste sorting and recycling (internal & external)
REDUCTION OF ELECTRICAL ENERGY
  • Planned and already carried out integration of formerly decentralized areas with similar activities
  • Retrofitting modern LED technology and lighting control 
OPTIMIZATION OF IT INFRASTRUCTURE
  • High usage of virtualization software for significantly reduced need for server units
  • Extended hardware utilization through investment in high-quality and efficient business products
  • Data deduplication using special software for significantly reduced size and number of hard disk storage devices
  • Digitization of administration processes for savings on printing devices and reduction of paper printouts

Research & Development

Technological Sustainability

SCHOTTEL has a portfolio focused on product durability. All components of the propulsion systems are optimized in terms of quality, flow behaviour, noise emission and power density and are continuously equipped with technological innovations. The resulting resource conservation and emission reduction as well as maintenance concepts for long-term use all contribute to sustainability.

HYBRID PROPULSION UNITS

Operation profiles of tugs or workboats are characterized by low motor loads for up to 90 percent of the operating time. In order to optimize propulsion systems for such loads and reduce emissions, SCHOTTEL has developed a hybrid-electric and a hybrid-mechanical solution.

CERTIFIED SEAL MONITORING SYSTEM

SCHOTTEL LeaCon is a sealing system certified by DNV which offers safe and reliable protection against possible contamination of the seawater. Separate seals to the seawater and to the gearbox side ensure that both incoming seawater and escaping gear oil are collected in an intermediate chamber (LeaCon chamber).

ALL-ELECTRIC PROPULSION SYSTEMS

The new SCHOTTEL LE-Drive ("Embedded L-Drive") enables free choice of the electric motor for fully battery-powered vessels. The elimination of the upper gearbox further increases mechanical efficiency while reducing fuel consumption.

CONTINUOUS PRODUCT OPTIMIZATION

Efficiency improvements through technological advancements, leaner designs with reduced material use, and proactive maintenance planning are some of numerous other ongoing optimizations that result in ship propulsion geared towards resource conservation, durability and thus sustainability.
