Abstract

Et rørleggingsfartøy innbefattende en rorbærende trommel (30) anbrakt med sin akse parallelt med baug-akterretningen av skroget. En sjøsettingskonstruksjon (36) består av teleskopisk bueformede elementer (38 og 58), hvilke er innbyrdes bevegelige for å variere sjøsettingsvinkelen. Rørinngripende klemmer (46 og 48) engasjerer røret langs en bueformet bane, og er resiprokerende bevegelig langs en bueformet bane for å strekke røret. Den bueformede bane har en buevinkel som er omtrentlig lik den gjenværende bueform av røret trukket fra trommelen. Sjøsettingsvinkelen kan også justeres ved bevegelse av vinkelen eller posisjonen til den bueformede bane i et plan som er hovedsakelig perpendikulært med trommelens akse. Et avslutnings- og gjenvinningssystem er anbrakt på sjøsettingskonstruksjonen, hvilken er bevegelig langs trommelen som en nivåspole.
