DEMO-HAVMERD-1 (illustrasjon) — Coating Passport

ROV inspection of an offshore / exposed pen (havmerd — offshore-steel structure, SalMar Ocean Farm-class). Weld-toe fatigue at a tubular node is the governing failure mode (DNV-RP-C203 S-N regime); 25% splash-zone section loss and net-attachment wear follow. The structure feeds a Veracity digital twin via strain sensors. NS 9415 + offshore-steel grounding, full EU AI Act-class tagging.

Findings detail

fatigue damage

confidence 90%167 framesimg-quality 84%severe

Utmattingsriss ved sveise-tå i et rørknutepunkt, ett gjennomgående riss med rustutslag. Styrende feilmodus for en eksponert stålkonstruksjon.

Location: Sveise-tå i rørknutepunkt, bæremedlem (1, 2, -4)

Recommended action: Strakstiltak: strukturvurdering; slip, sveis og kontroller med NDT. S-N-regime per DNV-RP-C203.

corrosion

confidence 87%138 framesimg-quality 82%severe

Tæring i skvalpesonen på et bæremedlem, anslått 25 % lokalt seksjonstap.

Location: Bæremedlem i skvalpesonen (0, 0, -1)

Recommended action: Mål godstykkelse; vurder forsterkning. Følg NORSOK M-501 for reparasjonsbelegg.

coating breakdown

confidence 83%112 framesimg-quality 80%moderate

Beleggnedbrytning med blottlagt stål under vannlinjen; lys rust ved et beskyttet medlem tyder på svekket katodisk beskyttelse.

Location: Bæremedlem under vannlinjen (-2, 0, -6)

Recommended action: Kontroller anoder og KP-potensial; flekkmal blottlagte flater.

net damage

confidence 84%99 framesimg-quality 79%moderate

Slitasje og begynnende løsning i festet mellom oppdrettsnettet og stålstrukturen. Mulig rømmingsvei ved videre slitasje.

Location: Festepunkt mellom oppdrettsnett og stålstruktur (3, 1, -3)

Recommended action: Stram og sikre festepunktet; inspiser nabofestene. Avvik (NYTEK23).
