Abstract

En bøyeavstiver (2) for hindring av urimelig bøyning av et langstrakt element, f.eks. et marint stigerør, i et område der det går inn i et rør, f.eks. et "I" eller "J"-rør montert på en plattform for utvinning av hydrokarboner, har en langstrakt hylse (8) med et gjennomgående hulrom som opptar det langstrakte elementet i bruk. Hylsen skal monteres ved hjelp av (i) en parende del (18) opptatt av røret og (ii) et aksialt lokaliseringsarrangement (6, 12, 14, 16). Det aksiale lokaliseringsarrangementet er utformet for å tillate minst noe vinkelbevegelse. Som et resultat bæres bøyemomenter av anlegget mellom den parende del (18) og røret. Det aksiale lokaliseringsarrangementet lider ikke av store bøyemomenter, og således avbøtes problemet med utmatting i dette området.
