Offshore pipeline protection against seabed gouging by ice: an overview
Offshore operators in the Arctic will rely on seafloor installations, notably pipelines, to manage and transport hydrocarbons. In icy waters, these structures are at risk of being damaged by gouging ice features, either icebergs or sea ice ridges. This phenomenon generally occurs when an ice feature...

Offshore operators in the Arctic will rely on seafloor installations, notably pipelines, to manage and transport hydrocarbons.
