Abstract

L'invention concerne un procédé destiné à l'accostage d'un bateau (10) contre une structure (20), consistant : à approcher de la structure (20), à mettre le bateau (10) en contact avec la structure (20), à mesurer la pression exercée par le bateau (10) contre la structure (20), et à commander le système de gouverne et de propulsion du bateau (10) pour atteindre une pression prédéfinie du bateau (10) contre la structure (20). L'invention se caractérise en ce que la commande du système de gouverne et de propulsion du bateau (10) est réalisée par anticipation des phénomènes de vagues prévus auxquels le bateau (10) sera exposé.
