The first relations between Sea Marconi and Vietnam date back to 2003, when a technological cooperation agreement was signed on “Clean Technologies” between the European Commission and Asian area. Twelve years later, last 11th and 12th May 2015, we were pleased to host a delegation of the Vietnamese national electricity company, EVN*. Their objective was to select the best technologyRead more

We are particularly proud to be able to recount another positive update in the “PCBs free Program for Japan” project: the arrival of the first order for the development of a system (DMU) for the dehalogenation of oils and transformers contaminated by PCBs. To completely understand the extraordinary nature of this news, we need to take a look at theRead more

In accordance with the IEC 62701 standard (Fluids for electrotechnical applications – Recycledmineral insulating oils for transformers and switchgear), Sea Marconi has developed an ad hoc project for one of the most important European suppliers of transformer oils. The project involves the implementation of a system for the assessment (technical-economical and environmental) of insulating oil properties before and after their reclamation (oil regeneration). InRead more

The partnership between Sea Marconi and local partner “Energy Solution SA DE CV“, a subsidiary of the NIETO group and an important player in the Mexican Oil & Gas sector, is enjoying great success. In 2014, the Sea Marconi process for the treatment of oils and transformers contaminated by PCBs, was successfully validated. The activity was performed in Torreón onRead more

Tra Amongst the activities performed at the end of 2014 that we haven’t yet mentioned, we are proud to note the important role played by Sea Marconi in South America, and in particular in Columbia. In September 2014, CIDET sent Sea Marconi a request for consultation and training for the implementation of the Stockholm Convention in Colombia. Vander Tumiatti went to Bogotà,Read more

Scenario Hydro Power Plant The transformer is located near a river dam with extreme logistical and environmental constraints. The option of changing the oil was discarded immediately because of the enormous difficulties in handling (see. Photo) around the transformer. At the same time the fuller earth techniques would not solve the functional criticalities of the system “oil – transformer”. NameplateRead more

For Sea Marconi 2013 ended with very interesting outlooks; one of these involves the opportunity offered by Mexico, engaged in the project for the destruction of PCBs: Environmentally Sound Management and Destruction of PCBs in Mexico. The project, started in 2009, involves the joint effort by the Ministry of Environment and natural resources (SEMARNAT), the Ministry of Foreign Affairs, UNDP (United NationsRead more
