Update of May 19, 2014 16:00
Five days after the explosion at the mine on May 13 Tuchia in Soma, the worst industrial disaster in the history of modern Turkey, victims rose to 301.
Charges of negligence, the judiciary has arrested 24 people, including managers and technical managers of the private company that manages the mine, the Soma Komur, including the general manager Dogru Ramazan, the finance director Ulu Ali and the operations manager Akin Celik. According to Turkish media, the prosecutors could also decide the arrest of the owner of the mine Alp Gurkan.
This morning, the Turkish Energy Minister Taner Yildiz declared that the extremely serious accident during the night between Monday 12 and Tuesday 13 at a mine in West Turkey was caused by a fault in an electric transformer.
“The incident is much more serious than we thought and is probably the accident with the highest number of victims ever in Turkey” continued the Turkish Minister.
LThe catastrophic event that triggered the explosion and fire caused black-out of the electrical system and collapse of part of the underground infrastructure (at a depth of 2000 m) where around 780 miners were working at the time. At the moment, there are more than 232 victims and 300 missing.
Catastrophic events of such scope stress the need for Life Cycle Management of oil-filled transformers focussed on loss prevention and environmental protection.
To achieve these objectives, Sea Marconi has developed a new line of integrated sustainable analysis, diagnostic solutions and treatments complying with the state of the art and with reference technical standards such as IEC 60422, IEC 60296, IEC 60599, IEC 62697-1. Since 1968, Sea Marconi has acquired exceptional international expertise in more than 50 countries with an ample case history of more than 3000 clients, 55000 transformers and a database of 170000 diagnoses.
Sea Marconi products, services, technologies and R&D are able to provide owners of electrical equipment with insulating fluids with assistance through the development of integrated protection programs based on best available techniques (BAT) and best environmental practices (BEP). This approach permits constant monitoring of equipment state of health and extension of service life in full compliance with the safety of the asset, public health and protection of the environment.
Criticality – TOP EVENT
“Explosion and/or fire of oil-filled transformer”
Catastrophic event with explosion and/or fire in oil-filled transformer and therefore loss of the asset with possible impact on the environmental matrices of the site (soil, subsoil, water, air). This event is classified amongst priority technological risks characterized by direct damage (loss of the asset), potential injuries to persons, indirect damage (loss of production) and environmental damage and is caused typically by an electrical fault with insulation failure and failure or inefficient activation of electrical and fire-prevention protective devices. It may also be the consequence of natural events or hostile actions. In the presence of persistent organic pollutants (PCB/POPs), this event may also be characterized by high level environmental impact deriving from the formation of highly dangerous cancerogenous, mutagenous, teratogenous compounds also at very low concentrations such as PCDD (dioxin) and PCDF (furans) with negative effects on public health and the environment (Stockholm Convention) and /or with emissions of SF6 (if present in the insulating fluid) with climate-change effects (Kyoto Protocol).
