The Geo-technical Research Group based at the Institute of Technology Sligo is currently developing deep-water anchoring systems for floating oil and gas platforms. Part of this development involves field testing of reduced scale anchoring systems.
Field testing was carried out in Lough Erne – one of Ireland’s deepest lakes (+70 m). Visual inspection of the mooring line was required at the lake bottom in order establish the penetration depth of the anchoring system.
The INTERSPEC Model 0911 underwater camera was chosen for the visual inspection of the mooring line. The camera was attached to a custom built cradle and lowered to the lake bed. The unit transmitted real-time imagery to the surface via Bowtech XX8024 cabling. The camera produced high quality images despite operating in turbid lake water with a visibility of less than 1 m.
