Vessels with Electric Drives

Marine vessels are the foundation of the global cargo system that represents a fairly large share of goods transportation. The volume of sea freight traffic keeps steadily growing, its composition is changing, and new trends are emerging.

In this regard, continuous improvement of technologies, in particular electrification of ship systems, is becoming an important issue of maritime transport. Such improvements can significantly improve performance of the ships.

The most widespread vessels with electrical components are:

  • Tankers
  • Icebreakers
  • Tugs
  • Ferries and passenger ships
  • Cruise ships
  • Research vessels

Vessels with Electric Drives are easy to maintain and do not require frequent repairs for optimal uptime and added cost efficiency.

In recent years, the maritime industry is characterized by a strong focus on environmental issues. Vessels with innovative electric propulsion can both meet performance requirements and maintain the world's environmental footprint. Due to the better environmental control, new laws, stricter regulations and increasing environmental awareness, vessels with electric propulsion are becoming an increasingly promising and popular solution.

Such power semiconductors as diodes and press-pack IGBT transistors are used in in the rectifier part and inverter part respectively of high-power frequency converters (propellers or pod drives) of nuclear icebreakers, gas carriers, tankers and supply vessels. Frequency converters of icebreaker-class thrusters are based on diodes in the rectifier part and IGBT transistors in the inverter part, too. Frequency converters for pumps, compressors, ventilation, trawl, crane and other equipment are based on mid-power diodes, thyristors and IGBT transistors.

Power semiconductors manufactured by Proton-Electrotex meet the highest requirements for durability, quality and precision. This is especially important in the sea transport conditions.

Proton-Electrotex has created a specialized laboratory of operational reliability that is mainly used to conduct classification and periodic tests, tests for reliability and to determine the ultimate useful life of the devices, allowing the company to produce high quality power semiconductor devices.

All manufacturing processes at Proton-Electrotex are organized in strict accordance with the requirements of the quality management (ISO 9001) and environmental management (ISO 14001).

Power semiconductors come in a variety of designs. Proton-Electrotex produces multiple types of semiconductors for vessels with electric drives in stud, disc and module designs.

Besides, Proton-Electrotex offers wide customization opportunities, taking into account individual customer requirements for technical parameters, connections and appearance of devices. Please contact the sales department for advice or leave your request online.
