The pipeline installation based on the laybarge method will inevitably produce waste gas, noise, and solid waste. Besides, it will carry sediments to the water when laying pipelines at the seabed and excavating the shoal at the landing terminal (Zhang 2003). The sediments formed in pipeline laying are mainly attributed to the submarine (plate) Chapter 19.

Jul 08, 2019Generally speaking, the environmental impacts of submarine cables are believed to be modest, although care must be taken during trenching and laying operations. The greatest adverse impacts are most likely to occur during installation when there is increased vessel traffic and disturbance of the seafloor as cable trenches are excavated and the cables are laid.(plate) Environmental impacts over the seabed and benthic impact of a submarine on the seabed(steel) Apr 24, 2015Environmental impacts over the seabed and benthic communities of submarine cable installation in the Biscay Marine Energy Platform (bimep) [Presentation].

Submarine Communications Cable What Are They?Procedure For Installing Cables Under The SeaEvolution of The Submarine Communications CableShark Bites to Espionage The Various Threats to Undersea CablesHow Are These Cables repaired?Environmental Impact of Submarine Communications CablesSince the fibre-optic cables used today are extremely small in diameter, they hardly cause any disturbance to the aquatic ecosystem or the sea-bed itself. The only exception is during installation and repairs. Then too, a very small perimeter is affected. Its negligible impact on the environment is recognised by the Joint Nature Conservation Committee (JNCC) and Natural England, the conservation advisors of the UK Government.

Impact of a submarine on the seabed - WIT Press

Under certain circumstances it may be desired to place a submarine on the seabed. In this static situation it is possible to shut down vital systems required for manoeuvring, hence avoiding the radiation of sound. This bottoming should be considered as a controlled collision; however this operation is not without risk.
