Cold bending of
submarine pipelines is a remedy for seabed obstructions, which otherwise
require preparatory or remedial work.
The method comprises cold bending in any plane to the
allowable strain criteria. The bending takes place at the seabed during the
installation
operations when additional length to follow an undulating
seabed is created.
Benefits are realized when crossing escarpments, achieving a
shorter direct route, contingency for seismic activities, mudslides,
environmentally sensitive areas and when short radius turns are required.
Units are supplied ready to be added to the pipeline in a manner identical
to common pipe sections.
