DNV GL Updates RP for Free-Spanning Pipelines

Offshore pipeline spans, due to uneven seabed or seabed erosion processes, can require huge and costly seabed interventions. The DNV GL recommended practice (RP) on free-spanning pipelines has been widely applied in industry to solve the problems related to free spans in pipeline design and operation. The RP has now been updated with project and research experience from the last decade on free-span dynamic response, particularly on structural modeling. DNVGL-RP-F105 enables significant costs savings, both in the newbuilding and operational phase. The scope of the RP is to provide rational design criteria and guidance for assessment of dynamic response of pipeline free spans due to combined
