Description

Die Erfindung betrifft einen halbeintauchbaren Schwergutfrachter. Derartige Frachtschiffe werden vor allem zum Transport von großen und schweren Stückgütern eingesetzt und zeichnen sich durch eine Tragfähigkeit von weitaus mehr als 10.000 t aus. Im Unterschied zu konventionellen Frachtschiffen. bei denen die Frachtgüter mit Kranen be- und entladen werden und denen daher Grenzen hinsichtlich der Abmessungen der zu befördernden Fracht gesetzt sind, eignen sich halbeintauchbare Schwergutfrachter in besonderem Maße zum Transport von sperrigen Gütern, wie beispielsweise komplette Bohrplattformen, Hafenkrananlagen oder mittlere bis große Wasserfahrzeuge oder Teile davon. Zu diesem Zweck bestehen halbeintauchbare Schwergutfrachter erfindungsgemäß aus einem vorderen Teil, in dem sich die Antriebsanlage sowie die Kommando- und Besatzungsräume befinden, und einem hinteren Teil, der im wesentlichen als hohlwandiger, Ballasttanks aufweisender Schwimmkörper mit einer ebenen Transportplattform ausgebildet ist.The invention relates to a semi-submersible heavy cargo carrier. Such cargo ships are mainly for Transport of large and heavy cargo used and are characterized by a load capacity of far more than 10,000 t out. Unlike conventional cargo ships. where cargo is loaded with cranes be unloaded and therefore have limitations in terms of Dimensions of the cargo to be transported are suitable Semi-submersible heavy cargo freighters in particular for transporting bulky goods, such as complete drilling platforms, port crane systems or medium to large watercraft or parts thereof. To this end consist semi-submersible heavy cargo carriers according to the invention from a front part in which the propulsion system as well the command and crew rooms are located, and one rear part, which is essentially hollow-walled, Ballast tanks having float with a flat Transport platform is formed.

Durch Fluten der Ballasttanks ist es möglich, den halbeintauchbaren Schwergutfrachter so weit einzutauchen, daß die Transportplattform unter die Schwimmwasserlinie abgesenkt wird, um schwimmfähiges oder beispielsweise auf einem Ponton gelagertes Frachtgut aufzunehmen oder abzugeben. Umgekehrt ist es durch Lenzen der Ballasttanks möglich, daß sich die Transportplattform unter das zu befördernde Frachtgut hebt, um dieses einzudocken. Neben dieser float-on/float-off-Methode kann das Be- und Entladen von Frachtgut auch mit der sogenannten roll-on/roll-off-Methode erfolgen, indem die Transportplattform des halbeintauchbaren Schwergutfrachters auf die Höhe des Hafenkais angehoben bzw. abgesenkt wird. By flooding the ballast tanks, it is possible to semi-submersible Submerge the heavy cargo freighter so far that the Transport platform lowered below the swimming water line is floating around or on a pontoon, for example to pick up or deliver stored cargo. Vice versa It is possible by Lenzen the ballast tanks that the Lifts transport platform under the cargo to be transported, to dock this. In addition to this float-on / float-off method can also load and unload cargo with the so-called roll-on / roll-off method is done by the Transport platform of semi-submersible heavy lift is raised or lowered to the height of the port quay.

Es ist bekannt, Frachtschiffe mit einem elektrischen Schiffsantrieb zu versehen. Bei dieselelektrischen Anlagen wird der elektrische Propellermotor üblicherweise von Generatoren gespeist, die durch Dieselmotoren und/oder Gasturbinen angetrieben werden. Ein dieselelektrischer Antrieb erfordert zwar im vergleich zu direkt mit dem Schiffspropeller gekuppelten Dieselmotoren höhere Investitionskosten, bietet aber den Vorteil einer effizienteren Nutzung und ermöglicht ein hohes Drehmoment an der Propellerwelle auch unter sehr hohen Lastbedingungen. Bei dieselelektrischen Antrieben besteht ferner nicht die Gefahr einer unzureichenden Maschinenkontrolle, wenn der Propeller, beispielsweise bei rauher See, aus dem Wasser kommt.It is known cargo ships with an electric Provide ship propulsion. In diesel-electric plants The electric propeller engine is usually from Generators fed by diesel engines and / or Gas turbines are driven. A diesel electric Although drive requires compared to directly with the Ship propeller coupled diesel engines higher investment costs, but offers the advantage of a more efficient Use and allows high torque at the propeller shaft even under very high load conditions. In diesel-electric Drives are also not at risk of insufficient machine control when the propeller, for example in rough seas, comes out of the water.

Bei konventionellen dieselelektrischen Antrieben sind alle elektrischen Anlagenteile binnenbords untergebracht und Motoren, Getriebe und Antriebswellen in einer Fluchtlinie ausgerichtet. Unbefriedigend sind hierbei auftretende hohe mechanische und hydrodynamische Verluste sowie eine im Vergleich zu außenbords angetriebenen Propellern beschränkte Manövrierfähigkeit. Nachteilig ist außerdem ein verhältnismäßig unwirtschaftlicher Kraftstoffverbrauch.In conventional diesel-electric drives are all electrical components housed inboard and Engines, gears and drive shafts in a line of flight aligned. Unsatisfactory here are high mechanical and hydrodynamic losses as well as an im Limited compared to outboard propellers driven Maneuverability. A disadvantage is also a relatively Uneconomic fuel consumption.

Aus der Zeitschrift Schiff & Hafen, Heft 11/1979 ist ein halbeintauchfähiges Schiff in Artikel "Condock I" zur Aufnahme von Leichtern oder schwimmenden Containern bekannt, das mit flut- und lenzbaren Boden- und Seitentanks zum Beund Entladen von Frachtgut nach der float-on/float-offund/oder roll-on/roll-off-Methode ausgebildet ist und als Hauptmaschine einen Dieselmotor im hinteren Schiffsteil aufweist. Zur Verbesserung der Manövrierfähigkeit ist eine Querschubeinrichtung im Vorschiff vorgesehen.From the magazine Schiff & Hafen, Issue 11/1979 is a semi-submersible ship in article "Condock I" for Recording of barges or floating containers known, this with floodable and deflectable bottom and side tanks Unloading cargo after the float-on / float-off and / or roll-on / roll-off method is designed and called Main engine a diesel engine in the rear part of the ship having. To improve the maneuverability is a Transverse thrust device provided in the foredeck.

Es ist Aufgabe der Erfindung, ein halbeintauchfähigs Schiff anzugehen, das sich ohne Schlepperhilfe oder Anker selbst auf Position halten kann und zur Aufnahme von sperrigen Gütern eine große, ebene Ladeplattform aufweist. It is an object of the invention, a halbeintauchfähigs ship to tackle that yourself without tug assistance or anchor yourself Can hold position and take up bulky goods has a large, flat loading platform.

Die Aufgabe wird dadurch gelöst, daß die Dieselmotoren Teil einer dieselelektrischen Antriebsanlage sind, wobei die dieselelektrische Antriebsanlage im Vorschiff angeordnet ist und zumindest einen elektrischen, unter dem Heck angeordneten Azimuth-Ruder-Propeller mit Energie versorgt, wobei die Ladefläche als ebene Transportplattform für sterrige Güter ausgebildet ist und wobei die Azimuth-Ruder-Propeller zusammen mit der Querschubeinrichtung eine präzise Positionsteuerung bei Absenkung auch beim Auftreten einer erheblichen Windkraft (6 bis 7Bf) erlauben.The object is achieved in that the diesel engines part a diesel-electric drive system, the diesel-electric drive system is arranged in the foredeck and at least one electric, arranged under the stern Azimuth rudder propeller powered, the Loading surface is designed as a flat transport platform for sturgeon goods and the azimuth rudder propellers together with the Transverse thrust device with precise position control Lowering even when a considerable wind force occurs (6 to 7Bf) allow.

Von Vorteil ist es, die dieselelektrische Antriebsanlage im Vorschiff anzuordnen, so daß sich hinsichtlich der Transporteignung des Schwergutfrachters eine optimierte Ausnutzung der Schiffsräumlichkeiten ergibt. Eine Anordnung der wesentlichen Anlagenteile im Vorschiff gewährleistet eine größtmögliche Variabilität zum Be- und Entladen von Frachtgut auf der auf diese Weise keinen baulichen Beschränkungen unterliegenden Transportplattform im Achterschiff.It is advantageous to use the diesel-electric drive system in the Vorschiff to arrange so that in terms of transport suitability of the heavy goods freighter optimized use of Ship premises results. An arrangement of the essential Plant parts in the foredeck ensure the greatest possible Variability for loading and unloading cargo on the up this way, no structural restrictions Transport platform in the stern.

Von Vorteil ist es ferner, den Azimut-Ruderpropeller durch einen außenbords angeordneten Elektromotor anzutreiben, der durch zumindest einen von den Hauptmaschinen angetriebenen Generator gespeist wird. Die Verwendung von außenbords angeordneten Elektromotoren zum Antrieb eines oder mehrerer Azimuth-Ruderpropeller bietet den Vorteil einer besonders guten Manövrierfähigkeit. Diese in der Praxis unter der Bezeichnung SSP bekannte Antriebstechnologie zeichnet sich dabei durch einen geringen Schiffswiderstand bei den verschiedensten Schiffsrümpfen aus und bedarf keiner zusätzlichen Kühlung, da diese durch das den Elektromotor umströmende Wasser bewirkt wird. Darüber hinaus ist der SSP-Antrieb mit geringen Nutz- und Wartungskosten verbunden.It is also advantageous, the azimuth Rudderpropeller by to drive an outboard arranged electric motor, the by at least one of the main engines driven Generator is powered. The use of outboard arranged electric motors for driving one or more Azimuth Rudderpropeller offers the advantage of a special good maneuverability. These in practice under the Designation SSP known drive technology stands out thereby by a small ship resistance with the different hulls and no one needs additional cooling, since this by the electric motor flowing water is effected. In addition, the SSP drive associated with low utility and maintenance costs.

Dieses setzt sich zusammen aus 2.000 t als Kraftstoff für die Hauptmaschinen dienendes Schweröl (HFO 380), 172 t als Kraftstoff für die Hilfsmaschinen dienendes Marine-Dieselöl für das eine Ladekapazität von ca. 200 m3 vorhanden ist, 300 t Frischwasser, für das dementsprechend eine Ladekapazität von 300 m3 vorhanden ist, 25 t Schmieröl, 20 t Vorräte für die Crew, 20 t Ersatzteile und 15.463 t Nutzlast. Der mittlere Konstruktionstiefgang beträgt bei diesem Totgewicht in Seewasser mit einer spezifischen Dichte von 1.025 t/m3 in etwa 7,5 m. Dies entspricht dem Tiefgang bei Konstruktions-Freibord.The semi-submersible heavy-lift freighter has a deadweight of 18,000 t for design freeboard. This is made up of 2,000 t of fuel oil for the main engines (HFO 380), 172 t of fuel for auxiliary marine diesel for which a cargo capacity of approximately 200 m 3 is available, 300 t of fresh water, for which accordingly a cargo capacity of 300 m 3 is present, 25 t of lubricating oil, 20 t of supplies for the crew, 20 t of spare parts and 15,463 t of payload. The mean draft is at this dead weight in seawater with a specific gravity of 1025 t / m 3 in about 7.5 m. This corresponds to the draft design freeboard depth.

Der halbeintauchbare Schwergutfrachter weist ferner eine Ladekapazität von ca. 40 m3 für Schmutzöl und von ca. 5 m3 für Abwasser auf. Auf dem Vorschiff sind oberhalb des Vordecks Unterkünfte für 22 Mannschaftsmitglieder und 16 Passagiere vorgesehen. In dem Vorschiff sind weiterhin 3 als Hauptmaschinen dienende Dieselmotoren mit einer Drehzahl von ca. 720 min-1 angeordnet. Mit den als 9-zylindrige Reihenmaschinen ausgebildeten Dieselmotoren kann eine elektrische Leistung von jeweils ca. 3.645 kW erzeugt werden. Bei elektrischen Verlusten von ca. 8,7% vom Generator zum Abtrieb und ohne Versorgung des Bordsystems kann somit eine Leistung von 8.675 kW bereitgestellt werden.The semi-submersible heavy goods freighter also has a loading capacity of about 40 m 3 for dirty oil and about 5 m 3 for wastewater. On the foredeck, accommodation for 22 crew members and 16 passengers is planned above the foredeck. In the foredeck, three diesel engines serving as main engines are also arranged at a speed of about 720 min -1 . With the trained as a 9-cylinder inline diesel engines, an electric power of about 3,645 kW can be generated. With electrical losses of about 8.7% from the generator to the output and without supply to the on-board system, a power of 8,675 kW can thus be provided.

Der halbeintauchbare Schwergutfrachter ist ferner mit zwei als Dieselmotoren ausgebildeten Hilfsmaschinen für die Stromerzeugung des Bordsystems ausgerüstete die mit einer Drehzahl von 720/900 min-1 eine Generatorleistung von jeweils 720 kW liefern. Für Aufenthalte im Hafen und Notfälle ist ein dritter Dieselgenerator vorgesehen, der eine Drehzahl von 1800 min-1 und eine Generatorleistung gemäß den Bestimmungen der SOLAS aufweist.The semi-submersible heavy goods freighter is also equipped with two designed as diesel engines auxiliary machines for power generation of the on-board system that deliver a generator power of 720 kW each with a speed of 720/900 min -1 . For stays in port and emergencies, a third diesel generator is provided, which has a speed of 1800 min -1 and generator power in accordance with the provisions of SOLAS.

Als Schiffsantrieb dienen zwei Azimuth-Ruder-Doppelpropeller, die mittels außenbords angeordneter Elektromotoren angetrieben werden und eine Betriebsgeschwindigkeit von 14 kn erzeugen können. Dieser in Fig. 3 dargestellte, sogenannte SSP-Antrieb wird durch zwei elektrisch angetriebene Querschubeinrichtungen ergänzt, welche die Manövrierfähigkeit und Stabilität des Schwergutfrachters verbessern. Versuche ergaben, daß mittels der beiden Querschubeinrichtungen der abgesenkte Schwergutfrachter gegen eine Windkraft von 6 bis 7 Beaufort ohne weiteres präzise gesteuert werden kann.As a ship propulsion serve two azimuth rudder double propellers, driven by means of outboard arranged electric motors and an operating speed of 14 kn can generate. This illustrated in Fig. 3, so-called SSP drive is powered by two electrically driven shear thrusters complements the maneuverability and Improve the stability of the heavy cargo carrier. tries showed that by means of the two transverse thrust devices of lowered heavy cargo vessel against a wind force of 6 to 7 Beaufort can be controlled precisely without further ado.

Zum Befestigen des Frachtguts auf dem Frachtdeck stehen eine Vielzahl von Winden zur Verfügung. Schallschutzmaßnahmen, wie beispielsweise die räumliche Trennung von Maschinenräumen und Unterkünften, Geräuschkapselung der Unterkünfte auf dem Vordeck oder ein Schalldämpfung für die Hauptmaschinen gewährleisten ergonomische Arbeitsbedingungen. Der halbeintauchbare Schwergutfrachter ist innerhalb von 4 Stunden von dem abgesenkten Tiefgang von 18 m auf einen Tiefgang von 7,50 m anhebbar, indem mittels Druckluft die Ballasttanks leergepumpt werden. Durch den geringen Verbrauch der Hauptmaschinen von 46,98 mT/24hr kann der halbeintauchbare Schwergutfrachter, der je nach Anwendung auch ein Dockschiff sein kann, bei einem für die Berechnung zugrundegelegten Zeitraum von 360 Tagen 34,6 Tage länger unterwegs sein als vergleichbare konventionelle Schiffe. Dies bedeutet, daß zu den gleichen Betriebskosten eine Zusatzfracht transportiert werden kann. Die hohe Kraftstoffeffizienz ist auch darauf zurückzuführen, daß je nach Bedarf nur ein oder zwei Dieselmotoren der Hauptmaschinen am Laufen sind. Damit wird nicht zuletzt auch ökologischen Aspekten Rechnung getragen.To attach the cargo on the cargo deck is one Variety of winches available. Soundproofing measures, such as For example, the spatial separation of engine rooms and Accommodation, soundproofing of accommodation on the foredeck or provide soundproofing for the main engines ergonomic working conditions. The semi-submersible Heavy lift is within 4 hours of the lowered Draft of 18 m to a draft of 7.50 m liftable by pumping the ballast tanks by means of compressed air become. Due to the low consumption of the main engines of 46.98 mT / 24hr, the semi-submersible heavy-lift freighter, which may also be a dock ship depending on the application may, for a period of time used for the calculation 360 days 34.6 days longer than comparable conventional ships. This means that to the same operating costs transported an additional freight can be. The high fuel efficiency is also on it due to the fact that only one or two diesel engines are needed the main engines are up and running. This will not work Finally, ecological aspects have also been taken into account.
