Petronor, subsidiary of Spanish oil and gas company Repsol, is almost done with the works at the refinery of Muskiz, Spain.

Since 2008, the company has been involved in building a Fuel oil Reduction Unit (FRU) Plant with the help of a Linden Comansa 21 LC 550 tower crane, with 18 tons of maximum load.

The crane is property of company Duro Felguera, specialists in industrial and energetic projects, that forms, with Imasa and Cotinsa the temporary consortium that is in charge of the project. Linden Comansa's official dealer ALGRUSA, has carried out the erection of the crane, as well as the planning and execution of the different jacking-ups.

The 21 LC 550 18-ton works with a jib length of 80 metres, and its final height under hook has been 120 metres, for which it needed two tie frame collars and 94 500 kilos of ballast on the 6-metre wide folding cross base. The work of the crane is focused on the construction of a petroleum coke plant, where it is lifting and assembling pipes, support elements and different structures.

With these new facilities, Petronor intends reducing its fuel oil production, and increasing the production of other fuels such as gas, propane, butane, gasoline, coke, etc. This change is mainly owing to the progressive decrease of fuel oil demand - which is used especially for the maritime transport and industrial uses. On the other hand, the other fuels, especially the diesel oil, have experienced an increasing demand, to such a point that most of the product has to be imported.

For this important adaptation of the refinery, Petronor has invested around 835-million Euros.

The petroleum company also thinks that the construction of the new plants have generated around 1500 jobs, and when the project is finished, 100 direct jobs and around 240 indirect jobs will be created.
