Drilling well is carried out by derrick 11, derrick 11 can stretch out platform by corresponding track and work, the well during work
The original position of frame, which is available, can be used as work-yard, and loop wheel machine 6 mainly carries the various lifting operations on platform, flat
During platform carries out well workover, the well repairing device of platform needs to complete by loop wheel machine 6, and shoe 7 can increase cylindrical leg 4
Mud lower stress area, reduce unit area stress, ensure platform standing state can safety and stability, helicopter deck 8 holds
The task of helicopter takeoff and landing is carried on a shoulder pole, at sea carries out communications and transportation with land faster, the area in life building 9 work more
The platform bigger of work provides comfortable living guarantee for the personnel on platform, and lifeboat 9a in emergency circumstances pacifies in platform generation
For the national games to send platform personnel, the positioning that fore body side pushes away 10 pairs of platforms plays crucial effect, can be moved in side surface direction, led to
It crosses with the movement of 12 front-rear direction of afterbody propeller coordinate and completes to be accurately positioned, afterbody propeller 12 is capable of providing oneself of platform
The bottom of platform is taken in shoe by boat function, shoe collecting post 13 completely, reduces resistance during from boat, carries out remote
Ensure that platform can smoothly stand on barge, be more convenient the transport of platform, piling machine 18 is by driving piles when transporting platform
Front and rear movement, the upper deck using platform of bigger in a state that the standing place of platform is constant are carried out on machine slideway 14
Area beats more wellbores, and the rack on cylindrical leg 4, by mechanical movement relative motion, is put down with the gear in Gu Zhuan areas 15
Platform main body moves up and down during rack-and-pinion moves, and drilling tool, which is stacked, to be placed in institute 16 needed for drilling platforms
The apparatus such as the drilling rod wanted, LNG tank body rack 22 stretch out the main body of platform, LNG tank body are placed on LNG tank body rack 22
17 and natural gas liquefaction device 21.
Fig. 3 shows the A-A sectional views in Fig. 1, i.e. machinery deck layout drawing, and Fig. 4 shows the B-B sectional views in Fig. 1,
Bilge deck plan, platform need various equipment during work, the power supply of equipment need host burning recover the oil or
Person's natural gas energizes, and the intermediate product generated among the equipment of drilling well well workover and the process of load work is required for special cabin,
Main body on platform is the staff that lives, and ensures the necessary cabin of daily living needs of personnel to complete to store,
, it is necessary to carry out certain ballast to platform platform is made to be in the state top-uped during platform floats, spud leg, which enters mud, to be needed to press
The enough gravity type spud legs of water tank offer are provided and reach stable standing state.
Fig. 5,6, show lifeboat arrangement position, in order to ensure when bad weather occurs, the work of platform
Making personnel can successfully survive, and lifeboat 9a is totally-enclosed, after working platform personnel fully enter, can cover lifeboat
9a, after opening lifeboat emitter, under the action of impact force, lifeboat 9a rapidly flies out platform, totally-enclosed to protect
Card quick be capable of when leaving life building it is safe swim in sea, in the state of normal work, lifeboat 9a is in life building
Inside exposing to wind and rain from external environment, so as to improve the security performance of lifeboat and its device.
Fig. 7 shows the D-D sectional views in Fig. 2, natural gas treatment plant layout drawing.LNG tank body 17 and natural gas liquefaction
Device 21 is all placed on LNG tank body rack 22, can avoid occupying the expensive real estate of upper deck 1, LNG tank body rack 22
It is fixedly connected for truss structure with main platform body, lighter in weight, in the process that the process or platform of platform towage are navigated certainly
In the resistance that is subject to it is smaller.
Fig. 8 shows LNG liquefied natural gas purposes figures, is had during platform well drilling or oil recovery substantial amounts of natural
Gas is collected, and in normal circumstances, this portion of natural gas can all be taken as exhaust gas and directly burn, by the way that natural gas is received
The natural gas partial after natural gas pretreatment unit is needed to burn for host after collection, remaining natural gas passes through natural gas liquefaction
Device 21 is stored in after liquefying in LNG tank body 17, certain shipping channels can be opened up when be stored into a certain amount of when, with fortune
This part LNG is transported natural gas companies by defeated ship, and portion of natural gas can be supplied to host to be fired by gasification process
It burns, burns and provide electric energy for the daily machine work of full platform, so as to have the function that turn waste into wealth, the burning of natural gas will
The discharge capacity of carbon is reduced, has complied with the requirement of the main trend of national energy-saving emission reduction.
Fig. 9 shows natural gas Collection utilization flow chart.After drilling well to certain degree, generated in drilling process
Natural gas is collected by platform collection device, and the natural gas being collected into partly is directly used in after natural gas pretreatment unit
Host burns, remaining is stored in after carrying out liquefaction processing by natural gas liquefaction device 21 in LNG tank body 17, LNG tank body 17
Interior natural gas by partly burning after natural gas gasifying device for host 20, it is remaining by cantilever beam 5 by LNG tank body 17
On lifting to cargo ship 19, then LNG tank body 17 is transported to land by cargo ship 19.
Figure 10 shows a kind of jack up Multifunctional marine platform operations flow chart.First with fore body side push away 10 and afterbody push away
The position of platform is adjusted to correct position into device 12, makes the pre- ballast tank 2g of complete deep bow, full deep-sea water tank 2i, first prism pressure
The ballast water emptying in water tank 3e and tail prism ballast tank 3h is carried, cylindrical leg 4 is put to seabed, passes through Shi Guzhuan areas

The piling machine (18) of topside carries out small-sized probing work, the life building during entire working platform during a standing
(9) place of clothing, food, lodging and transportion -- basic necessities of life is provided for personnel；
(b) using energy source process：After drilling well to certain degree, the natural gas generated in drilling process collects dress by platform
It puts and collects, the natural gas being collected into partly is directly used in host burning after natural gas pretreatment unit, remaining is logical
It crosses after natural gas liquefaction device (21) carries out liquefaction processing and is stored in LNG tank body (17), the natural gas in LNG tank body (17) leads to
It crosses after natural gas gasifying device and partly burns for host (20), it is remaining to be lifted LNG tank body (17) extremely by cantilever beam (5)
On ships that transport (19), then LNG tank body (17) is transported to land by ships that transport (19).
