L'invention concerne en outre un procédé conçu pour faire passer un tel système d'installation de forage modulaire transformable d'un mode de transport de site à un mode opérationnel. Des aspects de l'invention se rapportent à l'installation d'un mécanisme d'entraînement de tête, d'un treuil de forage et au transport de la structure de base dans son ensemble.
