Marine

Alconza has become an important point of reference in the marine market, being one of the leading manufacturers in the world (by total installed power) of ship electrical propulsion motors (OFSV, PSV, LNG, icebreakers, oceanographic and AHTS vessels, dredgers, flotels, ferries, defence ships, cable layers, pipe layers. etc.), and of different types of offshore platforms (drilling and oil and gas extraction, etc.) equipped with diesel-electric propulsion.

Its marine motors and generators are in strict compliance with international regulations and meet the restrictions imposed by the classification societies (DNV, RMRS, BV, etc.).

The following are some of the customers they supply with machinery for the marine sector: Wärtsilä (previously Aker Kværner Power & Automation Systems AS), IHC Drives & Automation, Rolls-Royce, EMC, Schottel, Imtech, Barillec, General Electric PC.

Motors

Low or medium voltage, synchronous or asynchronous, for all types of mechanical implementations (including mono-block or tandem), Alconza has provided a wide range of motors in compliance with international standards for different applications, equipped to operate with all types of variable speed controllers and suitable for generating low levels of noise and vibration.

Generators

For synchronous, low and medium voltage types, Alconza has the know-how to provide solutions for their customers on demand, always adapting to the requirements and restrictions of the customer whilst meeting international standards and classification society regulations.
