DNV SOFTWARE - A LEADING PROVIDER OF SOFTWARE FOR MANAGING RISK

safeguarding life, property and the environment

SesamTMPipelinePipeline Engineering Tool

DNV-OS-F101 Design Checks

- Burst during operation and system pressure test

- Collapse

- Propagation buckling

- Load combination, load controlled, load combinations a and b

- Load combination, displacement controlled, load

combinations a and b

Weight and Volume

- Calculates volume mass and dry weight of the

components that constitute a pipeline, i.e. steel, coating

layers and content

- Volume, mass and dry weight are calculated individu

ally and totally, per metre pipeline and totally for a given

length of the pipeline

End Expansion during operation and system pressure test

Upheaval Buckling- Safety level for given input

- Temperature, internal pressure and imperfection height that

will trigger upheaval buckling

- Cover Height to prevent upheaval buckling for a given safety level

- Simple and approximate

On-Bottom Stability

- Safety level for a given input

- Weight coating required to ensure stability for a given safety level

- Steel wall thickness required to ensure stability for a given

safety level

- Calculations according to DNV-RP-E305

Fatigue Screening

- Critical span length according to VIV on-set screening

criterion in DNV-RP-105

- In-line and Cross-flow

Reel Straining

- Max strain and ovality on reel

- Design check according to DNV-OS-F101

- Accumulated plastic strain

Reel Packing

- Amount of pipe on given reel according to, volume restriction

and weight restriction

The Pipeline Engineering Tool is a calculation tool for early phase pipeline assessment covering different

aspects of pipeline design. The tool is a VBA (Visual Basic for Applications) based program with a user-

friendly interface.
