Projects
No.1
Recovery of fallen and sunken object
Detached strut from hydrofoil jet ferry was located at north of Tsushima Island in 2007. Searching was extremely difficult due to unprecise sunken position and water depth 180m, but we made full use of sonar and underwater robot and managed to locate and recovered the strut in success by special designed chain net.
No.2
Search and Recovery of Sunken Air Craft
An air craft accidentally sank underwater off Korean in 2011. Under the condition of swift current and poor water visibility, we identified the position of the parts which widely spread on the seabed with 83m of water depth and recovered them by using ROV.
No.3
Search and Recovery of Sunken Sand Pump
We searched and recovered a sand pump, weighing 30t detached from a dredging vessel, from 60m of water depth by mix gas divers in 2014.
No.4
Recovery of an Anchor Chain Entangled with a Fix Fishing Net
An anchored cargo ship was washed into a huge fixed fishing net due to typhoon in 2018. The ship was towed out from the location after cutting the anchor chain itself heavily entangled with the net. Then we carefully recovered the anchor chain from 42m of water depth by using DP barge and mix gas diver in order to minimize the damage caused on the net.
No.5
Recovery of Collapsed Containers
A container vessel encountered rough sea in Pacific Ocean resulting some containers to collapse and fall overboard. We lashed the collapsed containers on deck, obtained permission to enter a port of refuge in Japan and offloaded the containers at a wharf. The damaged containers, which could not be offloaded by gantry cranes, were successfully offloaded by mobilizing mobile shore cranes.
