Abstract
The invention discloses a method for mounting a large-size discharging platform, comprising the following steps of: A. designing a tooling bracket and a bearing triangular bracket according to the self structure, the weight, the gravity center and the mounting position of the discharge platform, welding the tooling bracket at the designated position of a deck and mounting the bearing triangular bracket at the designated position of an outer board of a ship body at the bottom of the discharging platform; B. mounting a drawing and adjusting lifting lug at the designated position and arranging a hoisting lifting lug on the deck of the discharging platform; C. assembling a steel wire rope, a chain block and different shackles together; and D. hoisting a discharging platform structure to a mounting position, connecting the shackles connected with the chain block on the ship with the drawing and adjusting lifting lug on the discharging platform, tightening the chain block and releasing a hook of a hoist. According to the method for mounting the large-size discharging platform, the use time of hoisting on the sea is greatly shortened, the safety for the mounting process is improved, the time for using the hoist is shortened to 4-6 hours from 2-3 days, the cost is saved and the service efficiency of hoisting resources is improved.
Description
Technical field
The present invention relates to supertanker repacking Floating Production and store the emptying equipment field, relate in particular to a kind of installation method of large-scale landing platform.
Background technology
Along with oil field, deep-sea, the world is developed gradually; The world market stores emptying equipment (FPSO) for Floating Production and other maritime works's product consumptions constantly increase, and stores emptying equipment (FPSO) in operation 50-60% Floating Production at present and is converted by supertanker, in supertanker repacking (FPSO) process; Aboard ship to increase landing platform newly be one of Floating Production important engineering of storing emptying equipment (FPSO) repacking to stem deck extended spot all the time; The weight of general landing platform is the 150-230 ton, and the landing platform installation mainly is to lean on the large-scale floating crane handling to install in supertanker repacking Floating Production storage emptying equipment (FPSO) process in the past, owing to locate have line style to change from beginning to end; In needing very on a large scale, installation process repairs and adjustment; Can not carry out sealing at once, after sealing finishes, could allow crane pine hook, first landing platform installation process needs 2-3 days; So just increase the crane period of service greatly; Also carry out operation simultaneously night, this has just reduced safety of construction and has increased the quality control on construction difficulty, in order to reduce production costs; Enhance productivity and working security, a kind of science, reasonable, safe installation method design are absolutely necessary.
Summary of the invention
The purpose of this invention is to provide that a kind of installation method is simple, technology is succinct, the installation method of the large-scale landing platform of operating process safety.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of installation method of large-scale landing platform may further comprise the steps:
A, according to landing platform structure self structure; Weight, center of gravity, the installation site is through strength check design frock support and load-bearing spider; The frock support is welded on the deck assigned address, the load-bearing spider is installed in the ship hull plate assigned address of landing platform bottom;
B, according to frock support installation site, traction adjustment hanger is installed at assigned address, according to weight, center of gravity and landing platform constructional feature, the handling hanger is set on the landing platform deck;
C, according to frock backing positions, traction adjustment hanger position and landing platform structural weight, center of gravity, coupling steel rope, chain block, shackle and shackle fit together;
D, utilize the sea to hang the handling of landing platform structure to the installation site; Traction adjustment hanger on shackle of chain block bonded assembly and the landing platform on the ship is linked together, tighten up chain block, with crane pine hook; Through chain block landing platform is carried out leveling, centering, carry out the sealing welding then.
The frock support is two 5 meters frock supports in the said steps A, and said load-bearing spider is two.
Traction adjustment hanger is 4 among the said step B, and said handling hanger is 4.
Steel rope is that 2 diameters are that φ 80mm length is the steel rope of 7m among the said step C, and said chain block is 4 40 tons of chain blocks, and said shackle is 2 85 tons of shackles, and said shackle is 4 50 tons of shackles.
The installation method of the large-scale landing platform of the present invention; Greatly reduced large-scale sea and hung period of service and the safety that has improved installation process, will use the crane time to shorten to 4-6 hour, for company has practiced thrift cost and the service efficiency that has improved the lifting resource from 2-3 days; Production time can be controlled in and carries out daytime simultaneously; Heightened the safety and the construction quality of work progress greatly, and the landing platform structure installation method is simple, technology succinct, applied range, other and operating process safety.
The specific embodiment
The installation method of the large-scale landing platform of the present invention; Main through following steps completion: A, according to first landing platform structure self structure characteristics; Weight, center of gravity, the installation site, designing two height through strength check is frock support and 2 load-bearing spiders of 5 meters; The frock support is welded on stem deck assigned address, the load-bearing spider is installed in the ship hull plate assigned address of landing platform bottom; B, according to frock support installation site, 4 pieces of traction adjustment hangers are installed at assigned address, be provided with on the landing platform deck according to weight, center of gravity and landing platform constructional feature 4 pieces of handling hangers be installed; C, according to frock backing positions, traction hanger position and landing platform structural weight, center of gravity, be 7m steel rope, 4 40 tons of chain blocks, 2 pieces of 85 tons of shackles, 4 pieces of 50 tons of shackles through calculating 2 diameter phi 80mm length of coupling, it is fitted together; D, use the sea to hang the landing platform structure from the harbour handling to the installation site; Traction adjustment hanger on 4 pieces of 50 tons of shackles of the 30 chain block bonded assemblys of installation site preprepared on the ship and the landing platform is linked together; Tighten up 4 30 tons of chain blocks, can use 4 40 tons of chain blocks that landing platform is carried out leveling, centering on crane pine hook after tightening up; Carry out the sealing welding after finishing, withdraw from all facilities.
This installation method successfully uses; Compare with installation method in the past; Though the single-piece set-up time shortens seldom, greatly reduce large-scale sea and hung lease time and the safety that has improved installation process, practiced thrift cost; Also reach simultaneously the cost efficiency purpose and also be follow-up maritime works's product repacking establish a firm foundation, this field engineering achievement in research reaches leading domestic level.
