A l\u2019occasion de la Nuit de la data et de l\u2019IA, Eramet s\u2019est vu d\u00e9cerner le premier prix dans la cat\u00e9gorie \u00ab\u00a0Projets \u00e9quipes data & IA\u00a0\u00bb, pour son projet de maintenance pr\u00e9dictive du Transgabonais, le chemin de fer national du Gabon.<\/p>\n

Cette c\u00e9r\u00e9monie, organis\u00e9e chaque ann\u00e9e par Republik Data & IA, r\u00e9compense des projets innovants impliquant l\u2019utilisation de l\u2019intelligence artificielle. Un jury compos\u00e9 d\u2019experts issus de grandes entreprises fran\u00e7aises s\u00e9lectionne les meilleures initiatives dans plusieurs cat\u00e9gories.<\/p>\n

A noter que le projet a \u00e9galement \u00e9t\u00e9 s\u00e9lectionn\u00e9 parmi 600 dossiers<\/a> pour le Sommet mondial sur l\u2019intelligence artificielle organis\u00e9 par l’Elys\u00e9e les 10 et 11 f\u00e9vrier derniers.<\/p>\n<\/div><\/div><\/div>

IA et maintenance pr\u00e9dictive\u00a0: pr\u00e9venir plut\u00f4t que gu\u00e9rir<\/strong><\/h3>\n

Au Gabon, notre filiale Setrag op\u00e8re sur mandat des autorit\u00e9s l\u2019unique chemin de fer du pays\u00a0: le Transgabonais. Longue de pr\u00e8s de 650 kilom\u00e8tres, cette voie ferr\u00e9e relie les deux extr\u00e9mit\u00e9s ouest et est du pays, desservant 24 gares. Le train transporte le minerai de mangan\u00e8se de notre filiale Comilog, mais aussi d\u2019autres mati\u00e8res premi\u00e8res et \u00e9galement des voyageurs.<\/p>\n

\u00ab\u00a0Cette ligne, mise en service dans les ann\u00e9es 1980, a \u00e9t\u00e9 con\u00e7ue pour supporter 10 fois moins de trafic qu’aujourd’hui<\/em>\u00a0\u00bb, explique Jean-Loup Loyer, Chief Data Management & Analytics Officer chez Eramet. \u00ab\u00a0Par ailleurs, le climat tropical du Gabon rend le sol humide et mouvant, ce qui a pour effet de faire bouger la voie \u00e9galement<\/em>.\u00a0\u00bb<\/p>\n

Pour pallier ce probl\u00e8me, Eramet a mis au point un projet de maintenance pr\u00e9dictive bas\u00e9e sur l\u2019IA. Concr\u00e8tement, le Groupe a investi dans une locomotive d\u00e9di\u00e9e \u00e0 la maintenance. Dot\u00e9e de capteurs, celle-ci r\u00e9cup\u00e8re des donn\u00e9es de mesure (\u00e9cart entre les rails, forme des voies). Pendant plusieurs ann\u00e9es, cette locomotive a collect\u00e9 chaque mois des donn\u00e9es fiables permettant aujourd’hui de pr\u00e9dire, kilom\u00e8tre par kilom\u00e8tre, les points de d\u00e9gradation futurs sur la ligne.<\/p>\n

\u00ab\u00a0Avec cette connaissance, nous sommes en mesure d\u2019\u00e9mettre des recommandations aux \u00e9quipes de la Setrag en charge de la maintenance<\/em>\u00a0\u00bb, conclut Jean-Loup Loyer. \u00ab\u00a0On am\u00e9liore ainsi non seulement notre efficacit\u00e9 op\u00e9rationnelle mais aussi la s\u00e9curit\u00e9.\u00a0<\/em>\u00bb Un projet qui a s\u00e9duit le jury de la Nuit de la data et de l\u2019IA pour son originalit\u00e9 et son c\u00f4t\u00e9 concret.<\/p>\n<\/div><\/div><\/div>

L\u2019IA et la data au service de la performance op\u00e9rationnelle<\/strong><\/h3>\n

Le secteur minier conna\u00eet son lot de challenges, que ce soit en mati\u00e8re de performance, de responsabilit\u00e9 soci\u00e9tale ou de s\u00e9curit\u00e9. C\u2019est pourquoi Eramet d\u00e9ploie, sur l\u2019ensemble de ses sites \u00e0 travers le monde, plusieurs projets bas\u00e9s sur la valorisation de data.<\/p>\n

Au Gabon par exemple, un projet vise \u00e0 automatiquement \u00e9valuer les horaires d\u2019arriv\u00e9es du train de la Setrag via les cam\u00e9ras de surveillance sur le quai. Celles-ci peuvent d\u00e9tecter l\u2019arriv\u00e9e du train mais aussi le nombre de wagons ou le niveau de chargement des wagons \u00e0 minerai. Ces donn\u00e9es permettent de mieux planifier les op\u00e9rations et de mettre au point des plans d\u2019actions d\u2019am\u00e9lioration op\u00e9rationnelle.<\/p>\n

Au Gabon toujours, sur la mine de Comilog, on r\u00e9fl\u00e9chit \u00e0 la maintenance pr\u00e9dictive sur les engins miniers, comme le font d\u00e9j\u00e0 d\u2019autres entreprises mini\u00e8res. Des capteurs \u00e9quipant les v\u00e9hicules r\u00e9cup\u00e8rent des informations de fonctionnement, qui sont ensuite analys\u00e9es. Il est par exemple possible de v\u00e9rifier que l\u2019engin ne surconsomme pas de carburant, que les op\u00e9rations de maintenance sont bien r\u00e9alis\u00e9es, respectent les limitations de vitesse, etc. Les \u00e9carts relev\u00e9s peuvent donner lieu \u00e0 des sessions de sensibilisation ou formation.<\/p>\n

En Norv\u00e8ge enfin, l\u2019optimisation des proc\u00e9d\u00e9s est \u00e9galement \u00e0 l\u2019\u0153uvre au niveau des fours pyrom\u00e9tallurgiques. Sur le site d\u2019Eramet Norway situ\u00e9 \u00e0 Kvinesdal, des algorithmes d\u2019intelligence artificielle permettent aux \u00e9quipes data d\u2019Eramet de fournir aux m\u00e9tallurgistes des recommandations pour am\u00e9liorer le proc\u00e9d\u00e9 ou encore r\u00e9duire la consommation d\u2019\u00e9nergie des fours.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":24,"featured_media":51613,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":""},"categories":[32],"tags":[141,264],"class_list":["post-51623","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-groupe","tag-gabon","tag-transformation-numerique","nature-actualite"],"acf":[],"yoast_head":"\nLa data et l\u2019intelligence artificielle au service de la performance de nos sites - 18 f\u00e9vrier 2025 - News - Eramet<\/title>\n<meta name=\"description\" content=\"Le secteur minier n\u2019\u00e9chappe pas \u00e0 la r\u00e9volution de l\u2019IA.
