In case of non-fins-diving solutions it can be done different. shifting of work site day by day shall be enabled by installation of a remote-controlled sub-surface marker buoy with release system on last position of executed work, respectively work executed on previous days shall be inspected by means of underwater video (ROV or UW-drone) repeatedly General assumptions about the task: Total impact area to be restored will be ~2.300m² Work can be executed by divers in accordance with the requirements of DGUV Regel 101-023.
