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.A plumbing vessel including a rudder-carrying drum (30) disposed with its axis parallel to the bow-stern direction of the hull. A launching structure (36) consists of telescopic arcuate elements (38 and 58) which are mutually movable to vary the launching angle. Tube engaging clamps (46 and 48) engage the tube along an arcuate path, and are reciprocally movable along an arcuate path to stretch the tube. The arcuate web has an arc angle approximately equal to the remaining arc shape of the tube drawn from the drum. The launch angle can also be adjusted by moving the angle or position of the arcuate web in a plane substantially perpendicular to the axis of the drum. A finishing and recycling system is arranged on the launching structure, which is movable along the drum as a level coil.
