No.1
Wreck removal of a grounded vessel
A car carrier constituted total loss subsequent to grounding at west of Keelung, Taiwan on 10 November in 2008. The vessel was dismantled from upper structure to small blocks and pulled to shore by 8 sets of chain pullers (pulling capacity 300 tons each). Temporary road was constructed to gain access to and from the wreck and to surround the vessel to control and contain oil spill which was likely.
No.2
Wreck removal of the casualties Great East Japan Earthquake
There was a lot of casualty including cape size bulker to fishing vessel due to big waves occurred on 11 March 2011, and we conducted salvage services and wreck removal. Our activities fulfilled a role of restoring the devastated area.
No.3
Wreck removal of a sunken vessel
Following explosion, a chemical tanker sank at Seto Inland Sea of Japan on 15 December 2004. As hull was badly deteriorated to lose its strength due to explosion before sinking, underwater welding of 48 eye pads was required by divers which took one year. After load distribution of each lifting weight by eye pads, floating crane lifted the casualty. The operation was completed with safety control of diving work which was exposed to strong currents at depth of 60 m.
No.4
Wreck removal of a grounded vessel
Whilst on voyage in ballast, the vessel grounded on rocky shallows at Suwanose Island, Kagoshima Prefecture on 11 February 2017. The location was remote and logistic of salvage gear to the site was difficult, but salvage tug, personnel and gear and equipment were quickly deployed. At the outset we started oil extraction to prevent the expansion of environmental damage, and then tugs with sets of chain puller (pulling power 300 tons each) were used to pull out the wreck toward offing. We succeeded in removal of the wreck in one body without dismantling it into pieces.
