Alconza Customer Services: the most reliable and fastest solution for shipowners


The technical assistance demonstrates Alconza’s commitment to offer their customers an end-to-end service

Alconza’s Customer Services is the most effective and fastest solution to any potential issues that may arise with their electric motors and generators. This service offers the demonstrated ability to provide totally reliable repairs on board of vessels. Since Alconza designs and manufactures their own electric motors and generators, this makes their engineers the most suitable individuals to provide maintenance and repair services, accommodating any vessel or project circumstances, be it on dry dock, moored, in a harbour o even during offshore operation.

Alconza technical assistance is also characterised by the provision of speedy solutions to their customers, which is critical for any shipowner. The company’s service engineers can solve any issue related to its generators or electric motors, without creating any major inconveniences in the engine room and enabling the rest of activities on board to continue seamlessly.


The Customer Services goes beyond the set-up of the affected generators and includes the inspection of any other electric motor or generator provided by Alconza, guaranteeing the inspection and repair is carried out by professionals of the manufacturing company. Alconza’s Technical Service chooses the most adequate method and always uses original components and materials in the repairs.

Shipowners that have deposited their trust in Alconza have shared their great satisfaction with the results of the Customer Services and they particularly value the short leeway required to complete the servicing, minimising the vessel inactivity period. The service can see to any issues upon shipowners request and also offers a preventive maintenance option, which provides a better way to avert possible inconveniences with the equipment.


From the moment the maintenance service team receives a call to action, their professionals will travel to the required location in the shortest possible time to determine the scope of damages and assess the most adequate solution, in order to minimise the repair time and mitigate any negative impact. In this regard, although onsite assistance is much faster, it also represents higher complexity, mostly because of the limited space in the engine rooms. In any case, Alconza is prepared to provide the service in these conditions and it is quite common to carry out the repair directly on the vessel. The optimal decision is always agreed upon with the shipowner in order to minimise the negative impact in the vessel activity.

It is critical to carry out the engineering process, the materials supply and the equipment and tools design required for the repairs always taking into account the logistics of each situation. Once the materials and equipment are supplied, a team of qualified professionals will travel to the location and carry out the required improvements in the minimum possible length of time.


Alconza’s Customer Service represents in essence the end-to-end commitment towards their clients in the marine, hydroelectric and industrial sectors, from design and manufacturing of rotating machines (electric motors and generators), to the maintenance and management of original replacement of parts for any of their products.

Alconza will participate at the “Electric & Hybrid Marine World Expo 2019”


The international trade fair will take place in Amsterdam on 25th, 26th and 27th of June at the Amsterdam RAI Exhibition and Convention Centre.

The event will bring together exhibitors and visitors from all over the world to demonstrate the latest technological developments in electric propulsion and hybrid systems for the marine industry. The specialisation and the level of the exhibitors make this fair a must-attend event for shipowners, shipyards, marine companies and architects, port operators, etc.

Alconza invites all attendees to visit their stand, E6079, to show their electric propulsion for ships (OFSV, PSV, LNG, icebreakers, oceanographic ships, AHTS, dredgers, ferries, defense vessels, cable-layers, etc.) and different types of platforms (oil and gas oil drillers and extractors, etc.).

Taking part in this important event, Alconza reinforces its commitment with the technological innovation that has turned it into a reference in motor and generator manufacturing in the marine, hydraulic and industrial generation and electromobility sectors.

Additionally, Alconza will be present at the Tech Presentation Area on Tuesday June 25th at 11.30 am, demonstrating its experience in “Integrating Electric Motors in Hybrid Systems”.

We look forward to seeing you there.  

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.
