Tenneelva HPP, new contract

Recently we have received an order from Energi Teknikk to provide one generator for Tenneelva HPP. For this project Energi Teknikk has been selected by Tussa Energi to provide the complete electromechanical package.

This time Alconza will design and manufacture one 4 MVA vertical generator at 750 rpm. This new generator increases our presence in the hydropower market in Norway.

Tussa Energi, an important player in the Norwegian market, trusts again in Alconza for this HPP. Alconza has manufactured several generators for Tussa Energi over a period of 20 years working together and we are sure Tenneelva will be also a successful project.

We are really proud to cooperate with this leading companies and to work again in Norway, where we have more than 40 generators installed.

Smakraftdagane 2018

Smakraftdagane 2018

Annual exhibition Smakrafdagane will take place next week in Norway. This exhibition is an important meeting point for all the main players who work in the small hydropower business in Norway. Between 20 and 22 March our Hydro Sales Manager and our Service Manager will be at your service in booth 32 at Quality Hotel Edvard Grieg (Bergen).

Norway has been one of our main business areas during the last years and we are sure it will keep on being for the next years. It will be a pleasure for us to see you at our booth to share ideas and strategy.

Vessel of the year 2018

Maersk Master: Vessel of the year 2018


Maersk Supply Service ´s vessel Maersk Master has been awarded Vessel of the year at the annual Offshore Support Journal Conference in London.
She is equipped with two PTI propulsion motors (Power Take In), five thruster motors and powered by five medium speed main generators from Alconza Berango S.L providing high reliability, fuel economy and dynamic position class 2.

The challenge was to design and build customized motors and generators due to the special requirements of the project. The solution was to develop special design criteria concerning the structural aspect taking also into consideration the interface with the rest of the equipments inside the engine and thruster rooms.  

The vessels will support Quadrant Energy’s Phoenix South and Van Gogh drilling campaign, which will initially cover three wells for a duration of 150 to 200 days. This highly modern and efficient vessel will be supporting Transocean’s semisubmersible rig DD1 with supply and anchor handling duties throughout the campaign.

Norwegian Gannet

Alconza will supply the electric propulsion system of the first of its kind hybrid vessel destined for aquaculture

Norwegian Gannet, will be the first hybrid vessel dedicated to aquaculture.

We are talking about a Factory-Ship, a new concept in the sector that seeks to reduce operating costs and above all to minimize the environmental impact.

Hav Line commissioned the design of the vessel and the manufacture of the engines to Wärtsilä, which will supply to Balenciaga shipyard with an integrated solution that combines a Wärtsilä 31 10-cylinder diesel main engine together with an electric propulsion system, manufactured by Alconza, capable of providing excess power on demand by reducing fuel consumption and absorbing engine load fluctuations, thus providing high efficiency while minimizing emissions.
Each delivery of the ship is calculated, will replace the use of about 50 trailers (7,000 a year), which will significantly reduce the polluting emissions associated with the entire process.
The ship, which will be launched in the month of April, has all the conditions to be one of the ships with the most technology that has left the Basque shipyards.

RRS Sir David Attenborough

Propulsion motors for the NERC delivered

 RRS Sir David Attenborough

Alconza is chosen again by Rolls&Royce Marine AS to design & manufacture the propulsion motors of the “RRS Sir David Attenborough” polar oceanographic icebreaker research vessel for the NERC, currently under construction at “Cammell Laird Yard” Liverpool´s Shipyard.

The vessel will operate in the arctic and Antarctic territory, being able to work during 60 continuous days in ice covered waters. In terms of design, the research vessel is the first of its kind, equipped with avant garde laboratory equipment and helideck, built in the United Kingdom.

Two propulsion lines, each one triggered by two tandem motors of 2.750kW at 140rpm, designed and fabricated by Alconza, under restrictive noise and vibration requirements, in order to commit with the SILENT-R class of DNV-GL. To reach this requirements an extensive and thorough design work has been performed, later on, validated on test bench
These motors have been satisfactory tested at Alconza´s facilities and delivered to the customer, adding a remarkable reference for Alconza.
