Definitions

  • the invention relates to an installation arrangement according to the preamble of claim 1.
  • the invention also relates to a method for constructing an installation arrangement with a jack-up platform and a barge.
  • From the DE 10 2011 118 712 A1 is a watercraft consisting of a barge and a dock ship known.
  • the dock ship completely encases the barge on the bottom side and makes it possible to lift the barge out of the water on four support legs using jacking systems.
  • U.S. 3,537,413 discloses a slotted vessel for accommodating a plurality of barges which can be brought to an equal height along its bottom by means of jacking systems to allow the barges towed individually in inland waterways to be seaworthy for the open sea as a compact unit .
  • the lifting pontoon has two side walls that are connected to each other via a loading deck.
  • the lifting pontoon can be lifted out of the water on four support legs.
  • GB 2567218A discloses a buoyant and lowerable ship that is used for installing jackets for wind turbines or the like. can be used.
  • WO 2019 081 440 A1 is a self-propelled offshore installation vessel known with a jack-up platform having a continuous main deck.
  • the jack-up platform has a recess in the rear area that is not continuous along the height, the floor of which is designed as the main loading deck. Components to be assembled can be loaded onto the main loading deck. Basically, the main loading deck is therefore dry during transport. It is also conceivable that the jack-up platform will be temporarily lowered, the main cargo deck will be flooded and a barge floats over the main cargo deck. The The main cargo deck is then drained by raising the jack-up platform through a ballast system so that the barge rests on the main cargo deck.
  • a disadvantage of the installation arrangement described is the fact that the jack-up platform requires a complex ballast system in order to be able to be loaded with a barge. In addition, draining the main cargo deck of the jack-up platform is problematic.
  • the object of the present invention is to provide a method for constructing an installation platform that avoids the disadvantages mentioned above.
  • the object is achieved in its first aspect by an installation arrangement with the features of claim 1 mentioned at the outset.
  • the installation arrangement consists of two main components: one is a barge and the other is a jack-up platform.
  • the term barge is to be understood broadly here; it may be self-propelled or non-self-propelled, preferably having a main cargo deck capable of transporting components for wind turbines, substations, oil rigs, etc.
  • the jack-up platform is self-floating. It can be self-propelled, ie have a drive that makes it possible to bring the jack-up platform from the port to the location without additional tugs.
  • the jack-up platform can have a crane, preferably a slewing crane, with which the components are unloaded from the barge and installed directly on the seabed or on parts that have already been created can become.
  • the jack-up platform has a hull which is slotted vertically to the sea surface, the term slot also having a broad meaning here.
  • the slot may have a width that is as much as half, 60%, 70% or even more of the width of the jack-up platform as a whole along the respective cross-section, and the slot may have a length that is over half, 60%, 70% or even 80% of the length of the jack-up platform.
  • the jack-up platform is preferably U-shaped in plan view.
  • a width of the slot is greater than a width of the barge.
  • a width of the slot in each longitudinal cross section is greater than an associated width of the barge.
  • the associated width of the barge means the width of the point on the barge that is arranged in the same cross section when the barge is fully inserted into the slot.
  • the slot is designed in such a way that the barge can move into the slot or also move out again.
  • the jack-up platform has mobile support legs. There may be at least three support legs, preferably four; but there are also five, six or any higher number of support legs conceivable.
  • the support legs are reciprocable along a height relative to the hull of the jack-up platform. They can be moved individually or in groups. Preferably, the support legs can be moved perpendicularly to the sea surface when the jack-up platform is floating in the sea.
  • Each of the support legs has a lifting mechanism. The lifting mechanism makes it possible to lift the hull of the jack-up platform out of the sea together with the barge retracted into the slot, so that in a raised position of the jack-up platform both the hull of the jack-up platform and the barge are no longer in contact with the sea surface.
  • the slot extends along the entire length of the retracted barge over the entire height of the hull, in other words: the jack-up platform does not have a main loading deck running under the barge.
  • the seabed side of the barge is open because the slot extends the full height of the jack-up platform.
  • holding means are arranged on the barge and the slot, which interact and hold the barge in the raised position in a fixed position on the jack-up platform.
  • the holding means can be designed in different ways.
  • the design of the jack-up platform according to the invention makes it possible on the one hand for a barge to be able to enter the slot without ballasting the jack-up platform, and on the other hand when the jack-up platform is raised it is possible to drain the slot immediately and quickly, since the jack-up platform does not have a main loading deck between the preferably parallel legs of the slot has.
  • the holding means can be formed, for example, by brackets that run along the two opposite inner sides of the legs of the slot.
  • the consoles can be continuous or interrupted.
  • the consoles can be attached on the inside the inner walls of the slot, but also as an inner extension of the seabed-side underside of the hull.
  • the barge can have corresponding lateral projections; in the second case, the barge is designed in its seabed-side width such that it can be moved over the consoles and the width is greater than the clear distance between the console front sides.
  • consoles have the advantage that an additional fastening step is not necessary.
  • the barge can simply drive itself or be pulled into the slot by appropriate ropes or pulling devices, and by raising the jack-up platform the barge rests on the consoles by itself and is therefore held in the raised position in a fixed position on the jack-up platform.
  • the slit may extend over at least 30%, preferably at least 50%, more preferably at least 90% of the longitudinal extent of the body.
  • the jack-up platform can stand stably on the seabed, at least one support leg is advantageously arranged on the bow side of the slot; two or more support legs can also be arranged on the bow side of the slot and, at the same time, two or more support legs in the stern section of the jack-up platform, i.e. in the area of the slot of the Jack-up platform, preferably one support leg can be provided on each leg of the slot.
  • the jack-up platform has a slewing crane, which makes it possible to lift components arranged on the barge, pivot them sideways and lower them at the desired location, for example to set up a wind turbine, a substation or an oil rig offshore, or to replace heavy components such as transformers offshore .
  • the invention is solved in its second aspect by a method having the features of claim 10.
  • the method is particularly suitable for constructing an installation arrangement in accordance with one of the installation arrangements mentioned above.
  • any of the above installation arrangements can be constructed by any of the methods described below.
  • the installation arrangement includes a jack-up platform and a barge.
  • the jack-up platform is brought to the location.
  • the jack-up platform has a hull slotted vertically to the sea surface with a slot having a slot width slightly greater than a width of the barge, the slot extending along the entire longitudinal extent of the retracted barge over the entire height of the hull.
  • the jack-up platform is self-floating.
  • the support legs are lowered until they are placed on the seabed. However, this step can also be done later.
  • the barge is driven into the slot of the jack-up platform, the support legs can be lowered before or after.
  • the holding means on the barge and on the slot cooperate and the jack-up platform is lifted out of the water with the barge.
  • a conventional jacking system located on the jack-up platform's support legs, is used for lifting.
  • the method according to the invention makes it possible to move the jack-up platform to location and to refrain from ballasting the jack-up platform on location.
  • the jack-up platform does not need to be lowered further into the sea.
  • the barge can drive into the jack-up platform brought to the location; It is also not necessary to ballast again, but the jack-up platform can be lifted out of the sea immediately with the barge retracted using the lifting system of the support legs.
  • the barge When entering the slot, the barge preferably forms a clear distance from the seabed over its entire longitudinal extent of its underwater surface. Therefore, the barge does not drive over a floor or a deck, in particular no main loading deck, of the jack-up platform, but it drives into a slot that is designed in the form of a recess that is largely completely open to the seabed, so that the barge with its entire underwater surface has a clear distance to the seabed.
