CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[001] This patent application claims priority from Indian Provisional Application 201821042587 filed on November 13, 2018.

TECHNICAL FIELD
[002] The present disclosure, in general, relates to the field of shipbuilding. More particularly, the present subject matter relates to an adjustable shore support bracket.

BACKGROUND
[003] Generally, in a shipyard ships are fabricated or welded of small structures known as units. Further, the units are aggregated to form massive structure known as blocks (sum of units from bottom to top). The blocks are assembled to a bottom of a ship known as bottom blocks and are sophisticated engineering structures as they vary in shape and size. Based on the ship design an aft part (front part) of the ship's body is made aerodynamic design to offer minimum resistance during sailing. The bottom blocks of the ship are fabricated from cut pieces of skids. Further, the fabricated bottom blocks are shifted on to a slipway using crane and placed at a desired location concerning an established centre line (C/L) and buttock Lines (6M off CL) on either side of the slipway. The fabricated bottom blocks are initially placed on the slipway and aligned with the installed unit or a structure. These installed structures are supported by support members (section angle, pillar pipes, etc.). Further alignment of the bottom blocks is achieved by using crane ramming of sliding wooden wedges locked with angle sections and the pillar pipes with land tiles (Foundation steel strips on the slipway for holding pipes). The arrangement of the wooden wedges over a steel keel blocks are placed at every alternate frame (distance between internal vertical load taking members of the ship, which is designed and fixed at 1500mm). These steel keel blocks are placed at 1300 mm height from the base of the slipway. However, during the process manual gas cutting, grousing of all support stays (angle sections), pillar pipes to land tiles are removed resulting in damage to the hull structure of the ship.
[004] Conventional system and method generally use a holding bracket for aligning of bottom blocks on the slipway. However, in some case angle sections are leftover or directly welded to the hull structure. Hence, precautions are taken to overcome the problem by designing a shore bracket. The shore bracket facilitates to adjust the alignment of the bottom block during repair.

DETAILED DESCRIPTION
[0011] Some embodiments of the present disclosure, illustrating all its features, will now be discussed in detail. The words “obtaining”, “identifying”, “determining”, “calculating”, “computing”, and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items. It must also be noted that as used herein and in the appended claims, the singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise. Although any systems and methods similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present disclosure, the exemplary, an adjustable shore support bracket is now described. The disclosed embodiments of the adjustable shore support bracket are merely exemplary of the disclosure, which may be embodied in various forms.
[0012] Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. However, one of ordinary skill in the art will readily recognize that the present disclosure for an adjustable shore support bracket is not intended to be limited to the embodiments illustrated but is to be accorded the widest scope consistent with the principles and features described herein.
[0013] The present subject matter relates to an adjustable ship shore support bracket. The adjustable shore support bracket may comprise of a bracket. Further, the bracket may comprise of a central member, a pair of members and a member. Further, the pair of members may comprise of a left member and a right member parallelly welded to the central member and the member is welded to the central member. The adjustable shore support bracket may comprise of an assembly opening. In one embodiment, the assembly opening on the member is used for adjustment of the bracket.
[0014] Referring now to figure 1A, an adjustable shore support bracket is illustrated in accordance with an embodiment of the present subject matter. Referring to figure 1B, a top view of the adjustable shore support bracket is illustrated in accordance with an embodiment of the present subject matter. In one embodiment, figure 1A and figure 1B are explained together.
[0015] In one embodiment, the adjustable shore support bracket 102 may comprise of a bracket 102 fabricated using IS 2062 steel plate. The bracket 102 may comprise of a central member 104, a pair members 106 and a member 108. The pair of members 106 may comprise of a left member and a right member parallelly welded to the central member 104 and the member 108 may be welded to the central member 104. Further, an opening 110 on the member 108 may use for adjustment of the bracket 102.
[0016] Referring now to figure 1B, a top view of the adjustable shore support bracket 102 is illustrated in accordance with an embodiment of the present subject matter. In one embodiment, the figure 1B is explained.
[0017] In another embodiment, the pair of members 106 may be inserted to wooden shore bracket available in a shipyard. The bracket 102 measuring an inner dimension of 350mm x 300mm for smooth insertion of the wooden shore bracket. Further, the assembly opening 110 having diameter 30mm may provide on the member 108 of the bracket 102 for easy movement during fitment, removal and securing of pillar pipes or the wooden shore at a predetermined angle thus reducing the load on a crane.
[0018] Further, the bracket 102 may mount at a predefined height (5700 mm) approximately from a base line of a bottom block. The bracket 102 is designed with 14mm plate to withstand the structural load of a shell impounded during the bottom block alignment to use at various locations of ships. The approximate weight of each fabricated bracket 102 may measure 30.5 Kgs to bear a maximum load of 90 tons. For additional loading, a front pair of the bracket 102 is mounted to an aft side of a shell, and a rear pair of the bracket 102 is mounted to a starboard side of the shell. However considering factor of safety of 1.3, safe working load for each bracket is 70 tons and the bracket 102 design thickness is not limited to 14 mm and may vary on additional loading. Further the wooden shore bracket and the pillar pipes are precisely adjusted by manual ramming of wooden wedges at the bottom side (slipway side) to achieve the required alignment of X, Y & Z.
[0019] Once the position of a front pair of the bracket 102 and the rear pair of the bracket 102 is secured on the shipyard, the position of the ship is secured on said brackets 102 by welding ship body at member 108 at its profile.
[0020] Referring now to figure 1C, a side view of the adjustable shore support bracket is illustrated in accordance with an embodiment of the present subject matter. In one embodiment, the figure 1C is explained.
[0021] In another embodiment, the member 108 may comprise of a curvature end to weld as per the shape of the hull bottom block for increase area of welding contact for securing the said ship in the required position till the completion of the ship building. Further, a rope may connect from the assembly opening to the wooden shore bracket to avoid the free fall of the wooden shore or the pillar pipes during transfer of the structural load of the shell. Further, a metal dog hook may be inserted to the assembly opening to secure the wooden shore bracket. Further, Die Penetration test (DP) may carried out on the welding area for quality check to confirm no cracks, pore holes and other welding defects exist.
[0022] Exemplary embodiments discussed above may provide certain advantages. Though not required to practice aspects of the disclosure, these advantages may include those provided by the following features.
[0023] Some embodiments of the adjustable shore support bracket for mounting and demounting of the brackets by gauzing, prior using of the ship as the welding may not consist of full penetration type.
