Dear all Marine Colleagues,
Known is that in the Far East real / really MEGA Projects in dredging are taking place.
Refer to Hong Kong and to Singapore.
At the same time look at the size of the vessels now in use and their giant dredge- arms and heads, besides the amount of sand taken from the seafloor at quite concentrated areas, the prime selected "borrow areas".
Obviously these areas are (likely) as well the "resting-place" of radio-telephone cables (copper and fiber-optics) and the (oil-and gas) pipelines, or at least may lay in the vicinity of crossing lines.
Has anyone of you heard of studies into this matter such as likelyhood of damage, special charting, action on these "bodies" in relation to shifting sands or "walking dunes"? (Trenched now may become exposed later!)
Who knows the existence of special seabottom charts on which locations of such cables and pipelines are indicated? ("OPL" Publications?)
I do cordailly thank you,
Known100
