Developments in subsea power and telecommunication cables detection: Part 1 – Visual and hydroacoustic tracking

Abstract: Subsea power and telecommunication transmission lines play an important role in today's world. They not only provide a link from shore to shore, but also connect an increasing number of offshore wind farms, wave power plants and other sea installations.Subsea cables have to be periodically maintained and checked for movement in terms of their position and burial depth. This task is difficult because of the dynamic environment of the sea floor, which can cause changes in position, depth, visibility and access t… Show more

“…In Part 1 of the present paper, the review focused on visual and acoustic detection (Szyrowski et al, 2013a). Despite their advances and benefits, visual tracking and hydroacoustic methods suffer limitations in the case of buried cables (Ortiz et al, 2009;Capus et al, 2010).…”

“…U nderwater cable connections are key pieces of equipment in topside and subsea facilities for electro-hydraulic control channel underwater production units, which provide underwater communications, power, and pulling forces to marine equipment, marine drag systems, and mooring systems (Szyrowski et al, 2013a(Szyrowski et al, , 2013b. However, underwater cables must operate under rough marine conditions, and at the seafloor, they are exposed to flow scouring, making them apt to bend or warp, which could result in underwater device failure.…”

“…The subsea cables need to be periodically checked, localised and repaired for faults. Localisation of the subsea cables is a difficult and costly task as dynamic sea environments keep on changing the cables' initial position and their burial depth [1].…”
