spreadsheets. Photo 1 and Photo 2 show the 
equipment configurations, at the office and in the 
work vessel, respectively. 
1.2 Features 
Enables easy processing (analyze, collect, save, 
search, convert, display, process) of various 
information and selection of screens (layers) as 
necessary by the use of GI S. 
Reduces administrative tasks by computerizing the 
production of drawings and spreadsheets. 
Displays the information on the monitor, preventing 
miscommunication and providing highly reliable 
information conveyance. 
Allows wider communication areas and simultaneous 
communications between multiple locations by using 
digital MCA communication. 
Construction personnel have real-time access to the 
information via Internet. 
Enables easy checking of construction qualities by 
utilizing the 3D image proces sing language. 
Marine weather forecasts and emergency information 
can be conveyed in addition to the construction 
manage ment information.

2. OUTLINE OF THE EXPERI MENT 
The Sy stem was able to transmit/ receive work vessel 
location data, weather information and emergency 
information us ing MCA, and verified Sy stem validity by 
demonstrating its ability to perform operation control 
of the sediment vessels, instructions on sediment 
discharge locations, management of sounding results, 
and automatic creation of operation control tables. 
Furthermore, the System demonstrated its ability to 
manage the construction progress with the 
construction datausing the Internet. 
2.1 Operation Control 
The monitor screen displays layers of geographic data 
of the construction area, locations of each work 
vessel, attribute information (such as vessel name, 
vessel type, company owned, etc.) and other 
information for safe operation control of sediment 
vessels and survey vessels and integrated 
management of the work in progress. 
Figure 3 and Figure 4 show the operation control 
screen and the vessel's attribute information,
