Abstract
The invention relates to the technical field of ocean engineering and ship construction, and in particular relates to a pile leg installation method for a self-elevating drilling platform. The method comprises the following steps of: 1, closing the self-elevating drilling platform on the flat ground or a dock; 2, installing a pile leg of the self-elevating drilling platform: (1) installing a crawler crane moving foundation fixture, and fixing the fixture on a main deck of the platform; (2) lowering the height of the drilling platform so that the height difference between the drilling platform and an outfitting quay is reduced to minimum, and driving a crawler crane of over 400 tons to the main deck of the platform through a trestle; (3) hoisting the pile leg formed after a third pile leg section and a fourth pile leg section are closed to the main deck by using the crawler crane; and (4) lifting the platform to the lower position of the top of a second pile leg section by using a lifting system. With the adoption of the method, the cost for a large-sized ultrahigh crane is reduced, the height for installing the pile leg is effectively reduced by using the lifting system, and the construction cost is greatly reduced.
Description
Technical field:
The present invention relates to a kind of ocean engineering and ship building technical field, particularly a kind of spud leg installation method of jack-up drilling unit.
Background technology:
At present, shoe location is mainly followed in the construction of jack-up drilling unit, and main body closes up, and the lifting basis closes up, and life building, helicopter deck close up and cantilever beam such as closes up at the step, and then spud leg and shoe are closed up.Owing to be subject to gauntry crane height (70-90 rice) restriction, just begin off the stocks after generally receiving two or three section spud leg, then tug the fitting-out quay and hang by the sea more remaining spud leg has been connect.
Above-mentioned jack-up drilling unit is in the spud leg installation process, require very high to weight-lifting equipment, especially at harbour pile extension leg, 300 feet, 350 feet and 400 feet platforms often will reach more than 120 ~ 160 meter height, use the somewhat expensive of large-scale loop wheel machine (hang in crawler crane or sea), cause the fabrication cost of platform to increase severely.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of spud leg installation method of jack-up drilling unit, and the method has realized saving the expense of using large-scale superelevation loop wheel machine, effectively reduces the height that spud leg is installed by self jacking system, greatly reduces laid down cost.Overcome existing spud leg installation method and need to use large-scale loop wheel machine, somewhat expensive, the deficiency that production cycle is long.
The technical solution used in the present invention is: a kind of spud leg installation method of jack-up drilling unit, and the method step is as follows:
One, jack-up drilling unit on the level land or dock close up:
(1) three shoe location;
(2) each body section of platform is placed on the moulding bed of suitably highly neatly arranging take shoe ground line-transect as benchmark closes up;
(3) after the body section weld seam was all finished, lifting basis and tightening device closed up, and the bow superstructure is closed up;
(4) after the level land closed up, first paragraph spud leg bottom closed up with shoe more first for first paragraph spud leg and second segment spud leg;
Two, the installation of pile legs of self-elevating drilling platform:
(1) crawler crane is installed and is moved basic frock, be fixed on the platform main deck;
(2) reduce the drilling platform height, make itself and the fitting-out quay discrepancy in elevation be reduced to minimum, by trestle crawler crane more than 400 tons is reached on the platform main deck;
(3) be lifted on the main deck with the spud leg of crawler crane after with the 3rd section spud leg and the 4th section spud leg folding;
(4) utilize jacking system that platform is risen on the lower side position, second segment spud leg top;
(5) utilize more than 400 tons crawler crane that the 3rd section and the 4th section spud leg are docked, adjust, locate and weld with the second segment spud leg;
(6) utilize jacking system decline platform to first paragraph spud leg middle part with upper/lower positions, repeat front (3), (4), (5) step, finish the spreading of all the other spud legs;
(7) after the spud leg spreading is finished, remove crawler crane and move basic frock, carry out again cantilever beam and close up.
The invention has the beneficial effects as follows: the present invention is owing to adopted the mode of platform self jacking system and crawler crane pile extension leg on main deck, thereby have and save the effect of using large-scale superelevation loop wheel machine expense, effectively reduce the height that spud leg is installed, the construction period is short, greatly reduces laid down cost.
The specific embodiment:
A kind of spud leg installation method of jack-up drilling unit, the method step is as follows:
One, jack-up drilling unit on the level land or dock close up:
(1) three shoe location;
(2) each body section of platform is placed on the moulding bed of suitably highly neatly arranging take shoe ground line-transect as benchmark closes up;
(3) after the body section weld seam was all finished, lifting basis and tightening device closed up, and the bow superstructure is closed up;
(4) after the level land closed up, first paragraph spud leg bottom closed up with shoe more first for first paragraph spud leg and second segment spud leg;
Two, the installation of pile legs of self-elevating drilling platform:
(1) crawler crane is installed and is moved basic frock, be fixed on the platform main deck;
(2) reduce the drilling platform height, make itself and the fitting-out quay discrepancy in elevation be reduced to minimum, by trestle crawler crane more than 400 tons is reached on the platform main deck;
(3) be lifted on the main deck with the spud leg of crawler crane after with the 3rd section spud leg and the 4th section spud leg folding;
(4) utilize jacking system that platform is risen on the lower side position, second segment spud leg top;
(5) utilize more than 400 tons crawler crane that the 3rd section and the 4th section spud leg are docked, adjust, locate and weld with the second segment spud leg;
(6) utilize jacking system decline platform to first paragraph spud leg middle part with upper/lower positions, repeat front (3), (4), (5) step, finish the spreading of all the other spud legs;
(7) after the spud leg spreading is finished, remove crawler crane and move basic frock, carry out again cantilever beam and close up.
Be understandable that, more than about specific descriptions of the present invention, only for the present invention being described and being not to be subject to the described technical scheme of the embodiment of the invention, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the present invention, to reach identical technique effect; Use needs as long as satisfy, all within protection scope of the present invention.
