Mitsui has developed a Disaster Monitoring Robot (nickname "Moni-Robo") which works instead of human being at an emergency site and/or an area where people cannot approach including nuclear facility. The operator controls the Moni-Robo from a remote and safe place to make picture taking, measurement of radio activity, running and manipulation to collect the information at around the disaster area. The Moni-Robo has achieved a prompter, safer and more accurate collection of information than before.

If the power goes out due to natural disaster like earthquake and typhoon, that's when the Emergency Generator of Mitsui Zosen Machinery Co., Ltd. really comes into play.

For emergency power source of communication, public service including hospital, drain pump at overflow of a river, hydropower station etc., this emergency generator reliably starts quickly to make a stable power supply to protect life and property of the people.

Inspection of main water pipe was a difficult job before because it inevitably caused a cut of water supply in a wide area. To cope with such difficulty, Mitsui has developed an Under-water Robot for Inspection of Water Pipe to be used in the water pipe, which has diameter of only 8 cm and can carry out inspection in the water pipe without cutting of water supply. This inspection robot is so small that can be inserted into the water pipe through an air vent valve at the manhole (inspection hole). Pictures of pipe's inside taken by the camera installed on the top and the side are displayed on the monitor on the ground through underwater cable. Wider use of this super-mini robot is expected to tackle the deterioration of water pipe more than before.

Mitsui is taking a leadership in non-destructive testing system to check the inside concrete and/or reinforcement steel of buildings. Mitsui's Non-destructive Testing System, couples with a combination of multiple transmission and receiving antennas, displays the inside condition of concrete in three dimensions on the screen by analyzing the reflected wave which passes through the concrete and reflects off the reinforcement steel and/or vacancy.

This technology has greatly contributed to the sound assessment of the building and to the enhancement of safety administration.
