Salvage work is effectively the heavy end of search and recovery. Search and recovery is up to around 40kg objects, Salvage work is limited by the capacity of the crane (around 12 - 20 tonnes) or the capacity of lifting bags (varies by size. 30kg to 500kg).
Whatever salvage work is needed to be conducted, I can help.
Contact me by mobile for salvage work as a detailed discussion will need to take place.
