Movable marine floating facility

The invention discloses a movable marine floating facility. The movable marine floating facility comprises a truss-type floating platform, a power device, a material storing warehouse system, a communication and navigation system; the power device is used for driving the truss-type floating platform to move and installed on the lower portion of the truss-type floating platform; the material storing warehouse system is used for storing materials and installed on the truss-type floating platform; and the communication and navigation system is used for receiving and sending signals and installed on the truss-type floating platform. According to the movable marine floating facility, the communication and navigation system and the material storing warehouse system are integrated, self-materials can be ensured, and meanwhile, unblocking of the signals is ensured; due to the fact that the power device is installed, flexibility of the marine floating facility is high except that the overall integration level is high; the movable marine floating facility can provide reliable communication relays for wireless communication of marine ships, and compared with building an island through filling the sea or building an aircraft carrier, the construction period is short, construction and using coat is low.
