Introduction
'Pipeline Protection' covers the mechanical possibility of damage to the pipeline. Pipelines can be damaged by several methods:
Methods of Protecting the pipelines can consist of:
This is often used for stability purposes. However, it also positions the pipeline below the seabed level, to remove the possibility of trawler fishing interaction.
Burial of a pipeline is a secondary operation after trenching. It uses the excavated amterial to cover the pipeline once it has been placed in the trench.
Rock dump over a pipeline provides stability and significant protection from both fishing and dropped ojects.
Mattress cover over the pipeline protects from fishing interaction and dropped objects to a limited extent.
A combination of these methods may be used to provide the required protection.
