Products Le LIMBoat est une solution complète et évolutive dédiée au suivi précis des paramètres critiques lors des opérations de forage offshore. Conçu pour s’adapter aux environnements marins les plus exigeants, il associe capteurs haute précision, architecture modulaire et enregistrement intelligent des données pour garantir un contrôle optimal des conditions de travail. Le système permet la mesure en temps réel de la profondeur, de la vitesse d’avancement (ROP), des charges hydrauliques, du débit et de la pression. Selon la configuration du navire, la mesure de la ROP peut être réalisée à l’aide d’un encodeur unique sur un système à 3 poulies, ou via deux encodeurs distincts : l’un pour la position du chariot sur sa glissière, l’autre pour la tête sur le chariot, notamment dans le cas de forages avec compensation de houle. De même, la mesure de la position du seabed frame varie selon les équipements : -Sur certains navires, un système à 3 poulies de type vibroflottation est utilisé. -Pour les bateaux conçus pour de grandes profondeurs, le seabed est souvent équipé de deux treuils et deux compensateurs de houle, nécessitant l’installation de quatre encodeurs pour assurer un suivi complet et fiable de sa position. Chaque navire étant unique dans sa conception et ses équipements, une pré-visite technique est indispensable avant l’établissement d’un devis définitif. Cette étape permet d’évaluer les contraintes spécifiques du chantier, de définir les points de mesure optimaux et de proposer une configuration adaptée, assurant ainsi une intégration efficace et une performance optimale du système LIMBoat. Products Le système LIMBoat associe des équipements de mesure précis et robustes pour un contrôle optimal des opérations de forage offshore.Grâce à son architecture modulaire, il s’adapte à une grande variété de configurations terrain, depuis les installations compactes jusqu’aux navires conçus pour des forages en grande profondeur. Unité PocketLIMLe PocketLIM, cœur du système, s’installe directement dans la cabine de forage. Son support dédié assure une fixation stable et un accès simplifié pour l’opérateur. Il centralise et enregistre l’ensemble des données collectées sur le chantier. Mesure de profondeur et vitesse sur la tête de forage (ROP)Un système mécanique à trois poulies est généralement fixé sur la tête de forage pour mesurer avec précision la profondeur et la vitesse d’avancement (ROP). Un câble est tendu entre le haut et le bas du derrick pour transmettre les mouvements au capteur.La connexion entre l’encodeur et la boîte de jonction est assurée par un câble spécialisé, garantissant une transmission de données fiable. Une calibration précise valide ensuite l’installation mécanique et électrique.⚠ Cas particuliers :Selon les navires, la ROP peut aussi être mesurée à l’aide de deux encodeurs distincts :Le premier, monté sur un système 3 poulies, mesure la position du chariot sur la glissière.Le second mesure la position de la tête sur le chariot, indispensable en présence d’un compensateur de houle. Mesure sur le cadre seabedSur la plupart des installations, deux roues de friction équipées d’encodeurs mesurent la position et la compensation dynamique du cadre seabed. Ces roues sont montées sur des supports soudés, fixés aux poulies correspondantes.Les données sont ensuite transmises via câbles blindés vers la boîte de jonction.⚠ Cas particuliers :Sur certains seabeds, un système à 3 poulies de type vibroflottation est utilisé.Sur les navires opérant en grande profondeur, le seabed peut être équipé de deux treuils et deux compensateurs de houle, nécessitant l'installation de quatre encodeurs pour un suivi précis de sa position. Intégration avec le PocketLIMLa boîte de jonction centralise toutes les données issues des capteurs de terrain et les transmet au PocketLIM via un câble BUS dédié. Cela permet une gestion unifiée, rapide et sécurisée des informations critiques du chantier. Boîtier Vibracan et afficheur d’alarmeLe boîtier Vibracan, également installé en cabine, reçoit l’ensemble des signaux terrain et contrôle les paramètres essentiels : pression, débit, efforts, vitesse…Un afficheur d’alarme est positionné à proximité pour alerter immédiatement l’opérateur en cas de dépassement de seuil ou d’anomalie détectée, assurant ainsi la sécurité opérationnelle du forage. Contrôle des charges, débits et pressionsDes capteurs de pression haute performance sont intégrés au circuit hydraulique et au circuit d’eau pour une lecture fiable des charges et débits.Les capteurs magnétiques fixés face aux roues des pompes détectent le passage des rayons, assurant une mesure précise du débit en temps réel.Toutes les données sont consolidées dans des boîtes de jonction, puis envoyées au boîtier Vibracan pour exploitation. Mesure de RPM et pression hydrauliqueUn capteur magnétique de vitesse est positionné sur la tête de forage. Il détecte la rotation grâce à des cibles métalliques fixées sur une pièce en mouvement. Le nombre de cibles peut varier selon les configurations, et doit être renseigné dans l’interface PocketLIM pour un comptage correct.Un capteur de pression complémentaire surveille la pression hydraulique de retour, apportant une information clé sur l'effort appliqué par la tête de forage.Ces données sont également envoyées au boîtier Vibracan via une boîte de jonction intermédiaire. Adaptabilité et pré-visite obligatoireChaque navire est un cas particulier, en fonction de sa structure, des équipements de forage installés et de ses contraintes techniques.Avant toute installation, une pré-visite technique est indispensable pour :Identifier la configuration exacte du forage,Déterminer le type et le nombre de capteurs nécessaires,Optimiser l’emplacement des composants,Proposer une solution personnalisée et un devis précis.

LIM SAS, LIM LOGGING LIM GROUP LIM SAS was incorporated in 1985 near Lyon in France, by Mr. Frédéric Malinet , a geologist. The LIM SAS corporate objects are the design, manufacture and marketing of measuring instruments and software applied to drilling for following purposes, geotechnical, special foundations, drill and blast, mining and hydrogeological exploration. To complete its product offering, on January 1, 2017 LIM SAS integrated Electromind , a company based in Luxembourg and specialized in the development, manufacture and marketing of logging (borehole geophysical) equipment. Electromind became LIM LOGGING. Beyond the simple design of measuring instruments, by offering hardware and software, LIM is positioned as a provider of complete solutions for the measurement and acquisition of drilling data, whether during drilling or in boreholes after their completion. LIM SAS & LIM LOGGING ’s main business areas are Special Foundations, Geotechnics, Hydrogeology, Mining and Extractive Industries as well as Underground Work (Tunnels).
