DNV-ST-F101

Submarine pipeline systems — pressure containment & wall thickness

DNV-ST-F101 is the offshore pipeline standard. Ask Deckhand to size a wall for pressure containment and the collapse and combined-loading limits, with every factor and assumption shown.

What you can ask it to do

  • Size a pipeline wall for design pressure (pressure containment) with fabrication and corrosion allowances.
  • Check system collapse and propagation buckling, and combined-loading utilisation.
  • Screen the same line across DNV-ST-F101, ASME B31 and PD 8010 in one report.

Questions

What does DNV-ST-F101 govern?

It is the standard for submarine pipeline systems — design, materials, construction and operation. The most-asked part is wall-thickness design — pressure containment, local buckling/collapse, and combined loading.

How is the minimum wall thickness determined?

From the design pressure and the pipe grade for pressure containment, plus fabrication tolerance and corrosion allowance, then verified against collapse and combined-loading limits. Deckhand reports the governing check and the utilisation.

Can you compare design codes?

Yes — wall thickness can be screened across DNV-ST-F101, ASME B31 and PD 8010 together so the code difference is explicit.
