Technips Deep Blue systems use fleein garages and if i remember richt, the tether wis aboot 850-900m.
Win a wurked for the U.S. government, they wanted6000m mainlifts and the management system was initially spec’d for 3000m excursions with soft armour tethers!!!!!!!!!!!
Aye, it wis a pain in the lentil soop, got it doon to 1800m tether but it wisnae much fun watchin some hero pilotin.
Fink it’s done awa’ wi noo tho, that wis aboot 1986 when tethers were CHUNKY!!!!
