[Prior Art] With the trend of extracting oil and natural gas from the seabed more than 150 meters deep, the demand for semi-soakable drilling units is also increasing. Ίο There are two conventional methods of constructing a semi-immersible drilling unit. The first is the so-called "sequence stacking method", which is used to manufacture semi-submersible drilling units in a "bottom-up" sequence. According to this method, the casing below the drilling apparatus, i.e., the pontoon, the struts, and the associated bracing are first built using land or water cranes. Then, the upper casing is assembled in the same manner as the lower casing. One of the main drawbacks of this approach is the large use of land and floating cranes. As such, the construction schedule often depends on the availability of a water crane. In addition, a large number of seams of the ship block also caused the construction schedule to be too long. On the other hand, after the installation of the entire drilling apparatus is completed, outfitting, main equipment installation, and commissioning must be performed on the drilling apparatus 20. As a result, this will lengthen the construction schedule and delay the commissioning of the equipment, particularly the drilling equipment, as it is located in the center of the upper casing. It is customary that the second method of constructing a semi-immersible drilling unit is at the same time ^42852 Annex 2 November 22, 1999 Amendment 9挲1 Known 2 More Repairs (More) Replacement Pages, Upper and Lower Cases and Subsequent Combine them. According to this method, the completion slave removes the upper casing from the barge and drags the upper and lower casings to a depth at which the seawater can accommodate the offshore position of the lower casing. Then, the lower casing 5 is sunk to the desired depth by ballast and counterweight' only the upper half of the pillars are exposed to the water surface. Such operations require temporary berths, several power pack systems, and complex logistics support. The barge transports and positions the upper casing above the lower casing. The barge must be secured against the lower casing prior to mating. Then, the floating barge is gradually lowered by 10 by the ballast until the bottom surface of the upper casing contacts the pillar of the lower casing. Finally, the joint is welded between the upper and lower casings. The main disadvantage of this method is that it is often used in high-risk operations in harsh, uncontrolled offshore environments. In addition, there may be many uncertainties in the operation. Regarding this issue, the safety and quality of the work will be the main concern. 15 Other methods of offshore construction of drilling rigs have been disclosed in a number of issued or published patent documents. For example, U.S. Patent No. 6,347,909, issued Feb. 19, 2002, discloses a method of constructing a drilling apparatus for transporting a deck at sea and mounting the panel on an offshore structure. The fascia is made entirely on a set of 2 d deep girders with jacking units. Then slide the fixed deck and the reinforcing beams onto the two floating boxes. Upon completion, the assembly is towed to the mounting base where the reinforcing beams are jacked up and at the same time the pontoons are sunk until the pontoons support the assembly. The lower jaw is then lowered onto the underlying structure and the pontoons are released. 1342852 Annex 2 Amendment of the 丨丨 22 ^ ^ ^ ^ 正 正 正 S S S S S S 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨A method of constructing an offshore platform by mating a self-floating substructure, a self-floating substructure.

Another patented method is U.S. Patent No. 5,924,822, issued on Jul. 10, 1999, which is incorporated herein by reference. The two separate pontoons each have two struts that extend upwardly from the pontoon. Each pontoon is provided with a plurality of ballast tanks that are depressed during the transport of the pontoons so that the deck is placed directly on the offshore substructure. With regard to the floating substructure, the pontoon is ballasted and simultaneously unloaded to the floating 15 substructure to transfer the deck to the floating substructure. U.S. Patent No. 5,237,949, issued August 24, 1993, discloses a method for constructing and assembling an offshore platform having a normal draft that exceeds the location of the construction site and platform. The depth of the waterway. The shell and the slab of the platform are separately constructed in a shallow dry dock (shaU〇w 2〇 f^Vingd〇ck). Then, the deck is raised to partially fill the dry dock and the housing floats to the position and the plaques are mated. Japanese Patent Application No. 56 74381, published on November 28, 1981, discloses a semi-immersible drilling device which is replaced by a pair of floating boxes and a top sill 7 1342852 9 Ι 4 2# repair (smelly) Page Attachment 2 On November 22, 1999, the revised board consists of several pillars. The end portions of the connecting members on the pillars and the end portions of the jaws are fixed. Then, the raft, the pontoon, and the struts are ballasted such that the central portion of the connecting members are aligned with the central portion of the slab while adjusting the inclination of the struts. 5 Although these patented methods have their efficacy in some cases, there is no need for a simple, safe and cost-effective method for assembling semi-immersible drilling units near shipyards and at shipyards. Preferably. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for constructing a semi-immersible drilling apparatus that is safe and less costly than other methods. Another object of the present invention is to provide a method of constructing a semi-immersible drilling apparatus using a land side of a conventional shipyard and a dry dock. The object of the present invention is to provide a method by which the upper casing can be constructed in a shipyard at the same time as 15 o'clock, thereby shortening the overall timetable of construction. The upper casing is built entirely on the land side on a skidding truss and a plurality of support towers, while the lower casing is constructed in a dry dock adjacent to the sliding truss. A support truss is mounted in the dry dock to support a plurality of sliding beams extending from a construction base 20 of the landside upper casing to a mating position above the lower casing of the dry dock . Once the upper and lower housings are formed, a hydraulic jack system is used to detach the upper housing from the mating position by sliding over the sliding beams. Subsequently, the mating operation is completed by floating the lower casing in the dry dock until it contacts and 8 1342852 is replacing the replacement page attachment 2 on November 22, 1999 to support the upper casing. Finally, the welding of the upper and lower casing joints is carried out. In this way, all mating operations can be performed under controlled conditions, thereby ensuring safety and work quality. 5 [Embodiment] Please refer to the drawings in detail. Figures 1 and 2 show the arrangement of the shipyard area including the dry dock for constructing and mating the semi-submersible drilling unit of the present invention. As shown in Figures 1 and 2, the semi-immersible drilling apparatus includes an upper casing 1 and a lower casing 2. During construction, the upper casing is supported by a sliding truss 3 adjacent to the land side of the dry dock 4. The truss 3 is designed as an upper casing that can also be slid over the sliding beam 6 using the sliding pillow block 8 during the unloading operation. An auxiliary support structure 5 or a support truss 5 is installed in the dry dock 4. The sliding beams or connecting members 6 extend between the supporting truss 5 and the bottom of the sliding truss 3. After the mating operation is completed, the connecting members 6 are removed from the supporting truss, the details of which will be explained below. The hydraulic cylinder of the hydraulic jack system 7 is attached to the first sliding pillow block 8 and a plurality of anchor blocks 9 are fixed to the distal ends of the sliding beams 6. The anchor blocks 9 are connected to the jack system 7 by a plurality of strand wires 14. The two barges 10 are positioned behind the support truss 5 on the dock floor. The barges 10 have tanks filled with ballast. The barges 10 are connected to the distal ends of the sliding beams 6 by tie bars 11. The barges 10 have a balance function to counter the upward movement of the sliding beams 6. 1M2852 Annex 2 Correction of November 22, 1999 Prior to the construction of the upper casing 1, a temporarily steep tower tower 16 was installed around the sliding truss 3 for supporting the upper casing i (Fig. 3). A five-way flat Di9 is placed below the upper casing 1 and a vertical staircase 17 and a horizontal walkway 18 provide access to the upper casing from the ground through the work platform 19. This component provides the method of the present invention with safe and friendly manufacturing characteristics. - Figure 4 illustrates the installation of the support frame 5 in the dry ship. As shown in the figure. The support truss 5 has an upper half 5A and a lower half (3). The lower half 5B has a plurality of connecting elements % with outwardly convex surfaces. The upper half 5A has a plurality of connecting members 5〇 having an inwardly concave surface, wherein the half of the concave 5B is the same as the radius of the convex portion 5C.

Figure 9 is a plan view showing the removal of the drilling apparatus by the support truss 5 in the dry dock 4. The method of the present invention provides several advantages over existing conventional well construction methods. It shortens the overall construction time by simultaneously manufacturing the upper and lower casings. Avoid the high risks and uncertainties of mating in harsh offshore environments, thus ensuring a high level of safety and quality. As a result, the upper and lower casings have excellent straightness and the equipment is likely to be tested early. The method of the present invention is provided with a suitable structural support for the upper casing which can handle variations in the loading pattern during the entire installation of the upper casing. A secure work platform is mounted beneath the upper housing to enhance the safety and friendly manufacturing characteristics of the present invention. The towers provide vertical and horizontal passages from the ground to the working platform below the upper casing. In addition, unobstructed sliding from the upper housing to the mating position is also provided. 15 The parts that support the trusses are easy to install, easy to align, and easy to remove. The dry dock floor does not require additional piling. Potential problems caused by uneven settlement in the sliding process have been ruled out and minimized or completely excluded between the lower casing and the branch frame #cross bracing 20 Obstruction. An additional advantage of the method of the invention relates to the exclusion of expensive ground anchors (gr〇und anch〇ring卩〇丨拊) for resisting the pulling force during sliding; the use of recoverable sliding beams, supporting the trusses and protecting the sliding Surface method. Adjusting the height of the structure with wooden wedges is better and can be corrected by the surface 12 1342852 Annex 2 99 years of the month of January 99. 11. 2 2 years of repair (defective) is replacing the stomach friction force constraint lateral mobile. 5 Although the invention has been described with reference to specific embodiments, the invention is not intended to limit the invention.
