Description

JOJO

Die Erfindung bezieht sich auf ein Verfahren zur Instandsetzung von Unterwasserteilen einer halbtauchenden Arbeitsplattform durch Dockung in einem Schwimmdock, wobei einer der aufgetauchten Rümpfe der Arbeitsplattform in das geflutete Schwimmdock eingeschwommen und der Rumpf damit trockengelegt wird und auf eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for repairing underwater parts of a semi-submersible Working platform by docking in a floating dock, with one of the surface hulls the working platform swam into the flooded floating dock and the hull was thus drained and on a device for carrying out the method.

Bei einem bekannten Verfahren der vorstehend beschriebenen Art (siehe GB-Z Shipping World and Shipbuilder, Mai 1976, S. 44 und 47) kann bei dem Dockvorgang eine für das Bohrgerät oder ähnliche Einrichtungen der Plattform nachteilige Schlagseite nicht vermieden werden.In a known method, the one described above Art (see GB-Z Shipping World and Shipbuilder, May 1976, pp. 44 and 47) can during the docking process a list that is detrimental to the drilling rig or similar devices on the platform is not avoided will.

Ferner ist aus der DE-OS 21 26 489 eine Teildockung eines Schiffes mit Hilfe eines Schwimmdocks bekannt, das eine auspumpbare Wanne — bestehend aus einem Bodenteil mit vier umgrenzenden Wänden — aufweist, von dem wenigstens eine aus mehreren senkrecht verstellbaren Rippen besteht, die abdichtend mit dem Schiffskörper in Berührung gebracht werden, so daß ein Teil der Schiffslänge, vornehmlich großer Schiffe — wenn auch mit großem baulichen Aufwand zwecks Anpassung an die Schiffsform — trocken gestellt werden kann.Furthermore, from DE-OS 21 26 489 a partial docking of a ship with the help of a floating dock is known, which has a tank that can be pumped out - consisting of a base part with four surrounding walls, at least one of which consists of a plurality of vertically adjustable ribs that seal with the Hulls are brought into contact so that part of the length of the ship, especially large ships - albeit with great structural effort in order to adapt to the shape of the ship - be put dry can.

Im vorliegenden Fall besteht die zu lösende Aufgabe darin, ein Verfahren der eingangs genannten Gattung und eine Vorrichtung dazu vorzuschlagen, mit denen bei geringst möglichem Aufwand eine Schlagseite der Arbeitsplattform während der Dockung am Ankerplatz &o vermieden wird.In the present case there is the problem to be solved to propose a method of the type mentioned at the beginning and a device for this, with which at a list of the working platform while docking at the anchorage & o is avoided.

Die Lösungen dieser Aufgabe sind in den Ansprüchen 1 und 2 beschrieben.The solutions to this problem are described in claims 1 and 2.

Eine vorteilhafte weitere Ausgestaltung der erfindungsgemäßen Vorrichtung ist im Anspruch 3 gekennzeichnet. Die Erfindung wird im folgenden anhand eines zeichnerisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigt (vornehmlich in perspektivischer AnAnother advantageous embodiment of the device according to the invention is characterized in claim 3. The invention is explained in more detail below with the aid of an exemplary embodiment shown in the drawing explained. It shows (mainly in perspective

In Fig. 1 ist die Wanne 5 längsseits des Rumpfes 2 gebracht, der durch Stabilisierungssäulen 3 mit der Plattform 1 verbunden ist. Die Wanne 5 wird in dieser Stellung von Schleppern gehalten (nicht dargestellt). Alle Tanks und die Wanne sind leer. Die Bodenwrangen 12 sind örtlich mit Pallhölzern belegt. In F i g. 2 ist die Wanne 5 geflutet, und mit Hilfe der Stabilitätstanks 9 werden Lage und Tiefgang gesteuert. Es werden Festmachcrleinen zum Rumpf 2 ausgebracht und Schlepper assistieren das Einschwimmanövcr (im einzelnen nicht dargestellt). Die Wanne 5 kann auch von innen unter den Rumpf 2 geschoben werden, insbesondere, wenn nach außen weisende Ankertrossen ausliegen.In FIG. 1, the tub 5 is alongside the fuselage 2 brought, which is connected to the platform 1 by stabilizing columns 3. The tub 5 is in this Position held by tugs (not shown). All tanks and the tub are empty. The floor walls 12 are locally covered with pallet wood. In Fig. 2, the tub 5 is flooded, and with the help of the stability tanks 9 are Controlled position and draft. Mooring lines are deployed to hull 2 and tugs assist the swim-in maneuver (not shown in detail). The tub 5 can also from the inside under the Hull 2 can be pushed, especially if there are outward-facing anchor cables.

Fig.3 zeigt, daß die Wanne 5 mittels Leinen und Schleppern in die richtige Position zum Rumpf 2 gebracht ist. Der Stabilitätstank 9 und der Ausgleichslank 8 werden entleert. Der Wannenrand 12 taucht dann in kurzer Zeit aus dem Wasser aus. Die Wanne 5 wird soweit gelenzt bis der Rumpf 2 einige Zentimeter austaucht. Die Wanne ist nun begehbar. Wie F i g. 4 erkennen läßt, ist der Rumpf 2 um einige Zentimeter angehoben. Das restliche Wasser in der Wanne 5 wird in die Ausglcichstanks 8 und in die Ausgleichstanks 8 und in die Stabilitätstanks 9 gepumpt. Dadurch wird die Wanne 5 trocken, die Schwimmlagc des Halbtauchers ändert sich aber nicht.Fig.3 shows that the tub 5 by means of lines and Tug is brought into the correct position in relation to hull 2. The stability tank 9 and the compensation lank 8 are emptied. The tub rim 12 then emerges from the water in a short time. The tub 5 is peeled until the trunk 2 emerges a few centimeters. The tub is now accessible. Like F i g. 4 recognize leaves, the fuselage 2 is raised by a few centimeters. The remaining water in the tub 5 is in the Equalization tanks 8 and into the equalization tanks 8 and into the stability tanks 9. This will make the tub 5 dry, but the swimming position of the semi-diver does not change.

F i g. 5a bis 5c lassen, wie anhand der Bezugszeichen erkenntlich, die Konstruktion der Wanne 5 erkennen.F i g. 5a to 5c show the construction of the tub 5, as can be seen from the reference numerals.

Die Hochsec-Arbeits-Plaüformen können sowohl als Halbtaucher, als auch als Arbeitsplattformen mit hochziehbarcn Slandsäulen ausgebildet sein.The high-sec work platforms can be used as semi-submersible as well as work platforms that can be pulled up Sland columns be formed.
