Abstract

Recently, due to the increase of port construction demand and transportation of ship blocks, the number of tug boats for towing large barges and floating cranes for salvaging sunken ship and bridge construction passing through sea is on the rise every year.

Floating cranes mainly use courses of south and west coasts of Korea where a lot of islands and narrow channels exist. Also, the area contains high risks like many fishing boats passing, fixed shore nets on the route together with strong tidal currents and unexpected changes of weather which makes the maneuverability of fleet decline and the possibility of marine accidents rise.

It is in this context that this study covered present state of floating cranes and tugboat fleets.

Then the study moved on to Facilities and Equipment Standards and inspection methods of safe navigation of tugboats and barges.

Furthermore, the study came up with a cause and solutions by Case Analysis conducted by Korea Maritime Safety Tribunal on marine accidents related with tugboats and barges.

Finally, the study suggests 8 methods of safely navigating the fleet of tugboats and barges when carrying floating cranes on the basis of field experience. These methods will be a lot of help for those people on board.
