Subsea, Pipelines & Integrity

From line sizing to end-of-life integrity — ask in plain language and Deckhand runs the real calculation against DNV, ASME and PD codes, with every assumption traced.

What you can ask it to do

Wall thickness. Screen a pipeline wall across the design codes (DNV-ST-F101, ASME B31, PD 8010) and get a one-page report.
On-bottom stability. Check stability of a subsea line in waves and current (DNV-RP-F109).
Free-span / VIV. Screen a free span for vortex-induced vibration and allowable length (DNV-RP-F105).
Lateral & upheaval buckling. Check a line for snake buckling under pressure and temperature, and the cover a buried line needs.
Fitness-for-service. Assess a corroded line from wall-thickness readings against its design pressure.
Cathodic protection. Size sacrificial-anode protection for a pipeline, jacket, manifold, monopile or FPSO hull (DNV-RP-B401 / F103).
