Patent

CA 2356675

The invention relates to a semi-immersible heavy-lift cargoboat with floodable and freeable bottom and side tanks for loading and unloading cargo according to the float-on/float-off and/or roll-on/roll-off method. Said cargoboat also comprises a diesel-electric driving arrangement. Said heavy-lift cargoboat is provided with diesel engines being the main engines. Said diesel engines drive at least one azimuth rudder propeller. A lateral thrust installation is provided in the forebody in order to improve manoeuvrability. The trimmed attitude can be trimmed in relation to the cargo by placing water ballasting in the upper and lower tanks.

L'invention concerne un cargo pour marchandises lourdes semi-immersible comprenant un réservoir de fond et des réservoirs latéraux pouvant flotter et être pompés, destinés à charger et à décharger des marchandises selon la méthode dite de float-on/float-off et/ou de roll-on/roll-off, ainsi qu'une installation d'entraînement diesel-électrique. Ce cargo comprend comme principaux moteurs des moteurs diesel qui entraînent au moins une hélice de gouvernail azimut. Afin d'améliorer la manoeuvrabilité, il est prévu à la proue, un dispositif de poussée transversale. La position d'équilibre peut être compensée par introduction d'un lest hydraulique dans le réservoir supérieur ou inférieur des marchandises.
