Floating offshore facility, propulsion structure, and propulsion method of floating offshore equipment

摘要

Floating offshore equipment (1) is used for maintaining the position on the sea. A construct (20) for propulsion including a propulsion device (21) can be dismounted relative to the floating offshore equipment (1). A power drive source driving propulsion device (21) for the floating offshore equipment (1) is configured on the floating offshore equipment (1). Therefore, in the floating offshore equipment (1), the propulsion device (21) which is used during the sailing process from a manufacturer or a harbor to an offshore place but is not needed during the offshore operation is saved from an engine chamber (10), and the space of the engine chamber (10) is greatly reduced, and the space, for production and storage, of equipment for offshore equipment is increased greatly.
