Development of Unmanned Caisson Installation System (UCIS)

Unmanned Caisson Installation System (UCIS) is an unmanned and remote-control technology though wireless LAN for performing a series of operation involved in caisson installation, which has been performed on caissons by manpower. The system enables one operator in a remote control room to perform diverse works involved in caisson installation, such as pouring water into the caisson and manipulating winches, and thus sharply reduces the required manpower. The system also ensures the safety of caisson installation works since there will be no persons on the caissons. It also improves the efficiency and precision of the works since the IT-based system centralizedly controls the movement of caissons and pouring and discharge of water. This paper describes the performances of the system and an example of actual application of the system.
