Alconza receives an eligible investment of over EUR 800,000 for technological development


The investment comes from the Entrepreneurial R&D Program “Hazitek”, led by the Basque Government

Alconza has won an eligible investment of EUR 826,483 within the Entrepreneurial R&D support program “Hazitek 2018”, led by the Department of Economic Development and Infrastructure of the Basque Government. This way, the Berango (Bizkaia) company continues boosting its technology innovation commitment, which has made them the benchmark in engines and propeller manufacturing in the sectors of marine off-shore, hydraulic and industrial generation, special uses and electro-mobility.

The fund is part of the eligible investment received by the Irizar Group, of which Alconza is part of, which has a global scope of EUR 6,956,000. This investment will contribute to deliver Irizar Group’s project “iPower 4.0”, which has the objective of generating the necessary knowledge to digitally transform their buses manufacturing processes and the development of new products and services to achieve their electric vehicles’ third generation.

The manufacturing of electric engines is precisely one of the activity pillars of Alconza. As of recent, Metropolitan Transportation of Barcelona has added to their fleet four “Irizar ie tram”-model articulated bus units with a 230 kW-electric engine designed and manufactured by Alconza. These engines are also used to run the 18-meter “Irizar ie bus” buses. Moreover, the company manufactures 160 kW engines for buses of up to 12 meters.

Innovation in electric propelling systems is one of the areas Alconza has identified to use the investment received by the “Hazitek” Program, as the company is already committed to finding more environmentally innovative and sustainable solutions in the area of propulsion.

Alconza’s commitment to new technologies was also recognised in the previous “Hazitek” Program funding round, obtaining EUR 443,360 for a competitive project called “Undersea”.

Alconza engines already driving electric buses in Barcelona


The company, with its self-developed engines, is part of the powertrain in Irizar-manufactured ie tram units

Metropolitan Transport of Barcelona (TMB for its acronym in Spanish) and the representatives of Irizar e-mobility have introduced four 100% electric, zero-emissions Irizar ie tram buses which from December onwards will support the mobility of the citizens of Barcelona.

These buses will start operating on the H16 line (Pg. Zona Franca – Fòrum / Campus Besòs) and will join the two Irizar ie buses that have been circulating since 2014 and that help deliver cleaner and more efficient transport services to the city of Barcelona.

To deliver this project, Alconza has invested three million euros to design, develop and manufacture these new 230 kW and 160 kW electric engines for the whole “Irizar ie” range.

The higher power engines are aimed at the 18-metre “ie bus” and the articulated “ie tram”, whereas the 160 kW engines will be installed in the up-to-12 metre buses. These engines allow a fast charge in five minutes, carried out via a retractable pantograph, which is connected to the mains during the stops where the charging stations are located. The full battery charge provides the vehicle with 100% clean mobility and its carried out at the TMB bus garages overnight.

With the delivery of this project, Alconza reinforces its position as a provider of electric engines to the automotive, maritime, hydroelectric and industrial industries.


Operational reliability, Alconza motors and generators maxim.

DC Orisant-Alconza

All high power output rotating machinery of the multi-purpose 5.450m³ trailing suction hopper dredger (TSHD) DC Orisant has been delivered by Alconza.


We are speaking about 2.250kW exchangeable propulsion & dredging motors, 4.250KVA variable speed generators, 950kW jet pumps and 700kWthruster motors. The vessel was built by Royal IHC for joint venture consisting of Den Herder (Reimerswaal Dredging) and Group de Cloedt. Reimerswaal Dredging is a family-run business with over 50 years of experience in the mining of sand and gravel from riverbeds and seabeds.
The DC Orisant was developed with one key characteristic in mind: operational reliability. The DC Orisant boasts full system redundancy at every level, with a view to maximising flexibility and minimising downtime in the unlikely event that a component fails.
With this principle electric propulsion and dredging motors all manufactured by Alconza are fully exchangeable, assuring both key systems availability and minimizing the potential effects in the unlikely event of a motor breakdown, in addition, to be even more flexible and reliable they are double winding motors.
This ship is equipped with state-of-the-art technology, including an advanced Power Management System (PMS) that handles four variable speed generators manufactured by Alconza with special attention for electromagnetic performance, excitation and cooling system favouring optimum fuel economy and maximum reduction of CO2 & Nox emissions.
Dynamic Positioning (DP) also comes as standard, enabling high-precision positioning of the ship, to achieve it the vessel equips 3 thruster motors operating together with propulsion motors, all of them Alconza electric motors.
The multi-purpose custom-built gravel hopper DC ORISANT is on the shortlist for Dredger of the year, hopefully, they will be awarded on the November 20th ceremony.


Two Alconza electric motors for the RRS Sir David Attenborough, launched at Cammell Laird

Alconza strengthens its position as a manufacturer of low-noise electric propulsion motors for marine research vessels


Alconza has again positioned itself as a point of reference in the manufacture of electric propulsion motors for research vessels. This time it is two latest-generation 5,500 KW at 140 RPM motors incorporated into the RSS Sir David Attenborough, which was launched on 14 July in the British Cammel Laird shipyard. It will be sailing primarily in the waters of the Antarctic..

Marine research is the main task of the vessel, so it is essential for it to have silent, low-vibration motors in order to minimize the impact on the marine fauna and environment. In this respect it is worth noting that the two Alconza propulsion motors have a tandem configuration, they are directly connected to the propellers and they comply with the Det Norske Veritas (DNV) ‘Silent R’ standard.

The two electric propulsion motors are low speed so they do not need reduction gear and can operate from zero to 186 RPM. For its cooling system, Alconza has taken into account all the requirements on noise and vibroacoustics. These electric motors drive two Rolls-Royce propellers making up a propulsion package that has taken the ‘Polar Class 4’ technical requirements into account.

The low noise characteristics of the electric motors were decisive in the vessel’s compliance with the Lloyd’s Register (LR) Rules (CAC1), the most demanding in terms of structural noise and vibration. This compliance provides the crew with a high level of on-board comfort.

With its technological contribution to the RRS Sir David Attenborough, Alconza has demonstrated that it has the best technological and productive capacities to equip vessels of this type with solutions based on asynchronous motors with rigid mounting. This solution has many advantages over direct current motors on elastic support, which are normal in research vessels and make the propulsion package more complicated and more expensive.

As a first step to the delivery of the motors to the Cammell Laird shipyard, Alconza demonstrated the suitability of the technology used through Factory Acceptance Testing (FAT), in order to verify that the propulsion motors operate in accordance with the customer’s specifications.

RSS Sir David Attenborough is a research vessel that is owned by the Natural Environment Research Council of Great Britain. She will be operated by British Antarctic Survey, a body devoted to research in the Antarctic. It is 128 metres long and is considered one of the most advanced scientific ships in the world. She can sail for 60 days without refuelling and can break ice up to 1.5 metres thick.

The ship is capable of undertaking voyages of up to 19,000 nautical miles and being entirely self-sufficient in fuel and provisions, at the same time as optimizing the comfort and safety of the crew. Most of the passengers will be environmental scientists who will be carrying out their research on board the vessel. It therefore needs to have the best conditions of habitability and comfort, and Alconza’s technological input has made an outstanding contribution to this.

The name of the vessel is a tribute to the naturalist and scientific broadcaster David Attenborough, whose nature documentaries enjoy worldwide prestige because of their scientific rigour and their extraordinary audiovisual narrative, which is closely related to cinematography.
