Pipeline Lateral Stability (PILS)

Weight coating or armoring to ensure lateral stability of pipelines, flexibles, umbilicals and cables can be highly expensive. The JIP aims to reduce weight requirements while maintaining a safe and reliable stability design.

Challenges

Weight coating or armoring to ensure lateral stability of pipelines, flexibles, umbilicals and cables can be highly expensive. The JIP aims to reduce weight requirements while maintaining a safe and reliable stability design.

Solutions

Current design practice is based on hydro-dynamic load and soil resistance models that were developed >20 years ago. Models based on more recent research will be assessed for accuracy and applicability.

Benefits

The JIP participants receive a free software license for a new dynamic time-domain solver for on-bottom stability design.

A new guideline is issued describing the revised load and resistance models.

Value

Potential savings related to production, storage and installation due to reduced concrete coating (pipelines) or steel armouring (umbilicals).

Allow pipelines to be safely routed through seismic areas and achieve cost reduction, where such route results in shorter pipeline.

Case example: 5mm added steel on 10cm cross-section, 15km long: ~6MNOK.
