Description
Technical field
The invention belongs to field of ocean engineering, relate to a kind of natural gas processing treatment facility, specifically, relate to a kind of jack up liquefied natural gas platform.
Background technology
Existingly realize natural gas processing process (liquefaction), to store and the liquefied natural gas terminal of outer transmission function has following two kinds usually:
One is Floating Liquefied Natural Gas device, the liquefaction process of this device needs to take into full account movement overseas environment (as the marine stormy waves stream etc.) impact on treating process etc., usually need to increase design of material intensity, reduce equipment occupation space, technological process will have enough comformabilitys and safety; Storing mode is usually identical with liquified natural gas carrier (LNGC), adopts natural gas storage tank pattern, and because liquefied natural gas (LNG) tank is in floating hull, in tank body, rocking of liquefied natural gas is difficult to eliminate to the destructiveness of hull structure; In the waters that the depth of water is more shallow, due to its floatation characteristic, shallow water effect is difficult to overcome, and therefore, compares and is applicable to the darker waters of the depth of water;
Another kind is traditional liquefied natural gas terminal harbour, and this harbour is away from densely populated, and addressing requires that the wharf apron depth of water meets the drinking water requirement of liquefied natural gas carrier alongside, floor area and scale of investment large, production cycle is long.
Summary of the invention
The object of the invention is the weak point in order to overcome above-mentioned background technology, provide a kind of jack up liquefied natural gas platform, the natural fuels for shallow water/coastal waters, land gas-field exploitation provides the outer defeated terminal of an economic security.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of jack up liquefied natural gas platform, comprise main body, spud leg and natural gas compressing processing equipment, natural gas compressing processing equipment is located on the main deck of main body, the quantity of spud leg is four, longitudinally be arranged in four drift angle places of main body respectively, each spud leg is provided with elevator, elevator is fixed on main body, main body is provided with windlass near the position of spud leg, the anchor of windlass is located on the side of main body, multiple liquefied natural gas (LNG) tank is provided with in main body, the position that main body is positioned at natural gas compressing processing equipment both sides is respectively equipped with outer defeated arm, outer defeated arm is connected with liquefied natural gas (LNG) tank, the stern of main body is provided with life building.
Further, the position that described main body is positioned at natural gas compressing processing equipment both sides is also provided with at least one hoisting crane.
Further, described natural gas compressing processing equipment comprises multiple gas conservation module, and in order to carry out pretreatment and liquefaction to natural fuels, gas conservation module is connected with liquefied natural gas (LNG) tank.
Further, the top in described life building is provided with helicopter deck.
Compared with prior art, advantage of the present invention is: platform of the present invention is by the quick position operation in windlass and spud leg realize target marine site, and mobile flexible, can reusing good; Main body can rise to more than sea level under the support of spud leg, reduces the impact of wave, improves the stability of main body, thus effectively prevent liquefied natural gas and rock destruction to hull structure; In addition, this platform, also in conjunction with the design concept of artificial island, greatly facilitates the daily life of staff.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention;
Fig. 2 is plan structure schematic diagram of the present invention.
Wherein, 1, main body, 2, liquefied natural gas (LNG) tank, 3, spud leg, 4, life building, 5, helicopter deck, 6, gas conservation module, 7, elevator, 8, hoisting crane, 9, anchor, 10, windlass, 11, outer defeated arm.
Detailed description of the invention:
As depicted in figs. 1 and 2, a kind of jack up liquefied natural gas platform, comprise main body 1, spud leg 3 and natural gas compressing processing equipment, natural gas compressing processing equipment is located on the main deck of main body 1, the quantity of spud leg 3 is four, longitudinally be arranged in four drift angle places of main body 1 respectively, each spud leg 3 is provided with elevator 7, elevator 7 is fixed on main body 1, main body 1 is provided with windlass 10 near the position of spud leg 3, the anchor 9 of windlass 10 is located on the side of main body 1, multiple liquefied natural gas (LNG) tank 2 is provided with in main body 1, the position that main body 1 is positioned at natural gas compressing processing equipment both sides is respectively equipped with outer defeated arm 11, in addition also at least one hoisting crane 8 can be set, hoisting crane 8 can be fixed on spud leg 3 top, to expand lifting scope, outer defeated arm 11 is connected with liquefied natural gas (LNG) tank 2, the stern of main body 1 is provided with life building 4, the top in life building 4 is provided with helicopter deck 5.
In the present invention, natural gas compressing processing equipment comprises multiple gas conservation module 6, and in order to carry out pretreatment and liquefaction to natural fuels, gas conservation module 6 is connected with liquefied natural gas (LNG) tank 2.
Platform of the present invention, after shipyard has been built, directly can be dragged to target marine site by tugboat, under the cooperation of tugboat, in conjunction with the location before the anchor 9 implementation platform pitching pile of four windlass 10; Then by elevator 7, spud leg 3 is down to mud face, seabed, ballast water is beaten respectively again in the ballast tank around spud leg 3, under the effect of ballast water, spud leg 3 inserts seabed, and now main body 1 can rise to more than sea level under the support of spud leg 3, greatly reduces wave to the impact of platform; When platform needs to be shifted, main body 1 is down to sea level, and spud leg 3 rises, platform is floating, can move to new operating area by tugboat, adds the alerting ability that platform uses, and along with the increase of the marine site degree of depth, adapt with it by the mode lengthening spud leg 3 length.
After platform main body 1 rises to predetermined operation height, received by natural gas line and need gaseous natural gas to be processed, then deacidified by gas conservation module 6 pairs of natural fuelses, dewater, the removal of mercury, the series of process process such as liquefaction; After having processed by the natural gas storing of liquefaction in liquefied natural gas (LNG) tank 2, when the liquefied natural gas in storage tank reach a certain amount of after, by outer defeated arm 11, the liquefied natural gas in storage tank is flowed to carrier, thus realizes the outer defeated object of liquefied natural gas.
Crane capacity and the operating radius of the hoisting crane 8 on main body 1 meet platform operations requirement, namely directly the goods on other boats and ships can be winched to main deck, or the goods on deck is winched on other boats and ships, the function that implementation platform and external substance exchange, can meet platform device maintenance requirement of hanging thing used in addition.
Life building 4 can be used for working platform personnel to gas conservation module 6 Long-distance Control, and improve the safety of operation, also have enough spaces simultaneously and live for personnel, material storage, can realize the function of artificial island completely; In life building, 4 tops arrange helicopter deck 5, can realize taking off and landing of helicopter, and the traffic for working platform personnel provides convenient.
