Description

Schlauchtanker Bekannt sind Schlauchtanker für Flüssigkeiten oder fließbare Stoffe mit einem spezifischen Gewicht, das geringer ist als das des Seewassers, aus nachgiebigem Material mit einem stromlinienförmigen Bug, an welchem die Schlepptrossen angeschlossen werden können, sowie einem oder mehreren mit dem Tankerinneren in Verbindung stehenden Rohren zur Be- und Entladung.Hose tankers Hose tankers for liquids or are known flowable substances with a specific weight that is lower than that of sea water, Made of flexible material with a streamlined bow on which the towing cables can be connected, as well as one or more with the tanker interior in Connecting pipes for loading and unloading.

Die Aufgabe der Erfindung besteht darin, diese bekannten Schlauchtanker dadurch zu verbessern, daß bei gleichbleibendem Volumen der Gesamtschleppwiderstand im Seegang möglichst gering wird. Bei Untersuchungen über den Schleppwiderstand eines Schlauchtankers bei Seegang wurde festgestellt, daß der Gesamtschleppwiderstand von dem 20fachen Verhältnis von Länge zu Durchmesser des Schlauchtankers an asymptotisch einem Kleinstwert zustrebt. Erfindungsgemäß wird deshalb vorgeschlagen, daß die Länge des Schlauchtankers nicht weniger als 20mal so groß wie der Durchmesser ist.The object of the invention is to provide these known hose tankers to be improved by the fact that the total drag resistance with the same volume is as low as possible in swell. When investigating drag drag a hose tanker in rough seas it was found that the total drag resistance asymptotically from 20 times the ratio of length to diameter of the hose tanker strives for a minimum value. According to the invention it is therefore proposed that the The length of the hose tanker is not less than 20 times the diameter.

Es gibt auch Schwimmkästen, sogenannte Caissons, welche in Längsrichtung eine gewisse Biegsamkeit durch geriffelte Seiten der einzelnen zusammengefügten Körper aufweisen, wobei diese längs eines mittleren Haltedrahtes oder Gestänges zusammengefügt sind. Die Gesamtlänge zum Durchmesser der einzelnen Schwimmkästenteile beträgt etwa 1: 25, während aber jedes einzelne Teil nur eine Länge zum Durchmesser von etwa 11/2 :1 aufweist. Solche Schwimmkästen sind jedoch keineTransportfahrzeuge im Sinne der Erfindung, da sie in ihren Einzelteilen durch die rechtwinklige Ausbildung der Endflächen beim Schleppen einen sehr großen Schleppwiderstand haben, aber nur eine begrenzte Biegsamkeit in Richtung der Schiffsachse vorhanden ist. Der Querschnitt kann aber insbesondere nicht von der runden Form abweichen, wie im Sinne der Erfindung, da die gewellten, metallenen Seitenwandungen nur eine gewisse Elastizität in der Längsrichtung ergeben.There are also floating boxes, so-called caissons, which have a certain flexibility in the longitudinal direction due to corrugated sides of the individual joined bodies, these being joined together along a central holding wire or rod. The total length to the diameter of the individual swimming box parts is about 1:25, while each individual part only has a length to the diameter of about 1 1/2: 1. However, such floating boxes are not transport vehicles within the meaning of the invention, since their individual parts have a very high drag resistance due to the rectangular design of the end faces when towing, but there is only limited flexibility in the direction of the ship's axis. In particular, however, the cross-section cannot deviate from the round shape, as in the context of the invention, since the corrugated, metal side walls only result in a certain elasticity in the longitudinal direction.
