Definitions

  • This invention relates to a method for building a marine structure, to methods for building and transporting the upper structure thereof, to a vessel for use therein and to the structure thus built up.
  • Another known method is that the upper structure is built along a quay on a rigid supporting structure including supporting platforms standing in the water, and then to jack this structure up so that a pontoon may be moved below it, after which the upper structure is lowered by jacking it downwards until it rests on the pontoon, which is then tugged to the site of the lower structure.
  • This has been applied for a floating lower structure which may be moved up and down by ballasting and deballasting and which had legs between which the pontoon could enter and be moved.
  • the floating lower structure is in such a method moved to deep but quiet water, for instance in a bay or fiord, or it is built there and in this area the floating lower structure may take over the upper structure from the pontoon by lifting the lower structure, after which the combined marine structure is tugged to the final operating site.
  • This method is only suited for a floating and ballastable lower structure and in many cases requires quiet but very deep water, so that the possibilities of application thereof are limited.
  • the shape of the lower structure should suffice special requirements to allow the pontoon to be moved to a position between the legs thereof. It is also possible to convey the upper structure to the lower structure while the upper structure rests on two separate pontoons at a distance from each other, which gives more freedom in the design of the lower structure.
  • the present invention aims at improving such known methods and to supply a relatively cheap and rapid possibility of completing a marine structure, also in cases in which this has a lower structure resting stationarily on the sea bottom in areas with much wind and high waves.
  • a method for building a marine structure is first of all according to the invention characterized in that the upper structure thereof in at least for the greater part completed condition is made to be carried by a catamaran-shaped semi-submersible vessel with a great vertical movability by ballasting while floating, that this vessel is thereupon moved to the lower structure of said marine structure and positioned above said lower structure with the catamaran hulls one to each side of the upper part of said lower structure, and that said vessel is then ballasted to discharge said upper structure unto said lower structure.
  • 1'he present invention further relates to a method for transporting the upper structure of a marine structure, which method according to the invention is characterized in that said upper structure in at least for the greater part completed condition is transmitted from a stationary supporting structure or floating pontoon to a catamaran-shaped semi-submersible vessel with a great vertical movability by ballasting while floating by moving this vessel in deeply ballasted condition while floating to a position in which supporting parts thereof are positioned below parts of said upper structure, said vessel thereupon being deballasted to rise in order to take over said upper structure and to lift it from said stationary structure or floating pontoon to allow shipping of said upper structure on said vessel to the lower structure of said marine structure.
  • the upper structure may either be built at a site where no deep water is available, as this upper structure may be loaded onto a shallow pontoon and may then easily and rapidly, also without a crane or derrick, be taken over by said semi-submersible vessel in deeper water but close to the coast to be moved on such vessel to the lower structure of the marine structure, or may at least be built up near the coast in quiet water and then be taken over directly by the semi-submersible vessel if the water is sufficiently deep for doing this.
  • a horizontal displacement of the upper structure onto such a pontoon or semi-submersible vessel is not necessary if the said stationary supporting structure is present above water on poles or partly on a quay, as is known as such, so that this upper structure may be supported by such parts in such a way, thatt h e pontoon or the vessel for taking up and carrying the upper structure may be moved below such a structure and may be raised by deballasting to take over the upper structure to carry it.
  • a crane or derrick is normally needed, but in this case this is a crane which may be supported on the quay or other stationary structure and may thus easily have a large capacity and be used also in bad weather.
  • the building up of said upper structure from modules is less necessary than in other systems such as known systems indicated above, such building up from modules may also when using the present invention have advantages and be preferred for building up the upper structure on the supporting structure, in particular for large and heavy upper structures.
  • a supporting frame may be positioned, on which such modules may be positioned and built up or composed or positioned thereon in finished condition, said supporting frame thereupon being taken up by a pontoon or semi-submersible vessel as indicated above together with the combination of modules positioned thereon.
  • the upper structure will be finished substantially entirely on the supporting structure, it may be preferred in view of wind forces to assemble protruding and/or lighter parts of the upper structure such as quarters for personnel, a crane or derrick, a helicopter deck, etc., to the main upper structure only after the upper structure has been taken up by the catamaran-shaped vessel, which may take place in deeper water but for instance close to the coast, the conveying of the upper structure on the pontoon or the said vessel being facilitated by lower wind forces.
  • protruding and/or lighter parts of the upper structure such as quarters for personnel, a crane or derrick, a helicopter deck, etc.
  • a semi-submersible vessel is, as is known to the expert, a vessel of which the greater part of the buoyancy is present rather deeply below the water level to be influenced as little as possible by waves, and neither by the returning water circulation by the waves below the water surface, and preferably with a relatively small surface intersecting the water surface.
  • Such a vessel may reach such a depth by ballasting and if desired it may be deballasted so much that its floats giving the buoyancy are close to the water level to allow sailing or tugging with little resi-tance.
  • a catamaran-shaped vessel according to the invention is open at at least one end between the hulls for taking up in the bay thus formed a pontoon or lower structure of a marine structure, with a mainly open space above the bay and with supporting means to the side of said open space above the bay to carry an upper structure for a marine structure.
  • Such a vessel is preferably movable up and down in the water by ballasting and deballasting over more than 10 meters and, if desired, even over a distance of 30 meters with a lower position in which said supporting means are positioned close to the water level.
  • Figs. 1-3 inclusive show a quay 1 and, in front of it, in the water, supports 2 for two supporting platforms 3.
  • a frame is positioned on the one hand on the quay and on the other hand on the platform 3.
  • This frame consists of two longitudinal beams 4 parallel to the quay and two transverse beams 5.
  • the greater part 9 of the upper structure of the marine structure is built up from separate modules 6 on this frame. In this case there are eight modules in two layers of four. Such modules are intact boxes with in them engines and other machinery, storing rooms, separators, etc., for use in the marine structure. For clarity these modules have been shown with some mutual distances but in fact they will normally contact each other. They may, if desired, be connected by suitable means such as by welding or bolt-connections, and ducts for fluid and electric connectors may be guided through the walls of said modules from one module to the other.
  • a pontoon 7 is moved through the water to a position below the frame of beams 4, 5, said pontoon being provided with suitable supports 8, which may be fixed to the pontoon or loosely supported thereon as to vary their position and height easily.
  • suitable supports 8 which may be fixed to the pontoon or loosely supported thereon as to vary their position and height easily.
  • the pontoon it is ballasted so as to take up a position rather deep in the water, lower than the position shown.
  • the pontoon is now deballasted, so that it rises to take over the beam-frame 4, 5 with the upper structure composed of the modules 6 from the quay 1 and the platforms 3, these being now supported by the supports 8 on the pontoon.
  • This vessel 10 is a catamaran-shaped semi-submersible vessel. It has a deck 11 of a shape which, as seen from above (Fig. 5), is mainly U-shaped and between the two parallel hulls or floats 12 and legs 13 it leaves a free space as a bay 14, open upwardly.
  • the floats or hulls 12 are connected by a float-or hull-part 15 immediately below the connection of the legs of the U of the deck-structure 11.
  • This vessel is made so as to be adapted to be moved up and down in the water over a considerable height by ballasting and deballasting. For instance it may be moved over a height of 13 meters, from a draught of about 38 meters to about 25 meters.
  • the deck 11 has a flat load-supporting upper surface or a number of separate supporting platforms 16 at a distance corresponding to the distance between the transverse beams 5 of frame 4, 5. In ballasted condition the top surfaces of such supporting platforms 16 are position ed only a short distance above or about at the water-line. In this condition the pontoon 7 with the upper structure 9 as described on it, is moved into bay 14.
  • the pontoon 7 can be moved with the parts of the beams 5 protruding outside the pontoon immediately above such supporting platforms.
  • vessel 10 is moved by its own propulsion means or by being towed to the site where the upper structure 9 should be mounted onto the lower structure of the marine structure. For this movement the vessel 10 is deballasted as far as is desirable as a compromise between resistance, wind- and wave-loads.
  • the lower structure of the marine structure for instance a jacket of a marine platform, is indicated diagrammatically by dot-and-dash-lines 18.
  • the structure 18 is considered to be a structure resting on the seabottom and being a frame-structure, but this structure may also be floating mainly below the water-level.
  • Such structure may have any shape suitable for its purpose, for instance an upright cylinder.
  • vessel 10 is ballasted until the upper part of structure 18 is made to carry the upper structure 9 with the beam-frame 4, 5 by taking it over from vessel 10 which can now be tugged away or moved away by its own propulsion means. It is now possible to connect the upper structure 9 to the structure 18 and the entire marine structure thus formed can now easily and rapidly be completed and put into operation.
  • the beam-frame 4, 5 is taken up in the marine structure. If this is not the case, several measures may be taken to avoid this.
  • One of the possibilities is that the beams 5 are shorter than the modules 6, so that, when balasting vessel 10, the structure 18 takes up the upper structure 9 by contacting the lower surfaces of modules 6without contacting beams 5. In this way the frame-structure 4, 5 remains on the vessel 10.
