Abstract
The utility model discloses a workover platform is from system of breaking down, certainly the system of breaking down including each anchor of 2 ones of head and the tail, be used for the complete rotary propeller that receive and releases the anchor machine of anchor and be used for the barge dynamic positioning, prelude anchor machine and afterbody anchor machine and the prelude anchor that corresponds and afterbody anchor all arrange along amidship line bilateral symmetry, prelude anchor machine department sets up one and turns around the propeller entirely, afterbody anchor machine department is corresponding to set up two rotary propellers entirely. The utility model discloses a from the system of breaking down, be applicable to the multi -functional workover platform who takes advancing device certainly who shields the waters, utilize 4 anchor machine of head and the tail to fix a position the anchoring operation, form 4 restraints behind the anchor that falls to combine dynamic positioning system, to well workover position formation fixed action.
Description
Technical field
The utility model relates to a kind of system of certainly casting anchor being applicable to workover platform.
Background technology
Oil production market has oil-gas mining and the maintenance platform of many service sheltered waters.A lot of platform is limited by the restriction of prevailing condition, and technical merit is lower, does not configure Powered Propulsion unit, and anchor mooring positioning system also must rely on other ancillary works boats and ships.A large amount of material resources and other support boats of time coordination will be spent like this in operation process to carry out in berth adjustment and location, and economy can not be guaranteed.
Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of workover platform from casting anchor system.
For solving the problems of the technologies described above, workover platform of the present utility model is from casting anchor system, this certainly the system of casting anchor comprise head and the tail each 2 anchor, for the windlass of folding and unfolding anchor and the all-direction propeller for barge dynamic positioning, stem anchor and the afterbody anchor of stem windlass and afterbody windlass and correspondence are all symmetrically arranged along ship center line, described stem windlass place arranges an all-direction propeller, and described afterbody windlass place correspondence arranges two all-direction propellers.
Described stem windlass and afterbody windlass are single drum winder.
This workover platform adopts head and the tail power unit to arrange, achieves autonomous propelling and dynamic positioning, possesses basic manoevreability.At the initial and tail sections of platform, anchoring equipment is set respectively like this, when platform positions operation, in conjunction with dynamic positioning system (DPS), realizes locating anchor work more fast, independently.
The beneficial effects of the utility model:
1, workover platform is provided with complete mooring and anchoring equipment, and can not rely on Other Engineering ship and independently to fall anchor operation.Independent operation is convenient, can save a large amount of anchoring time, improves operating efficiency.
2, add and to be located on main body relatively simple, manufacturing cost is lower, and service efficiency is higher, possesses good economic benefit.
Accompanying drawing explanation
Fig. 1 is the lateral plan of workover platform of the present utility model.
Fig. 2 is the arrangement plan of windlass of the present utility model on workover platform.
Wherein: 1, stem anchor, 2, stem anchor, 3, afterbody anchor, 4, afterbody anchor, 5, stem windlass, 6, stem windlass, 7, afterbody windlass, 8, afterbody windlass, 9, all-direction propeller, 10, all-direction propeller, 11, all-direction propeller.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As illustrated in fig. 1 and 2, workover platform of the present utility model is from casting anchor system, this certainly the system of casting anchor comprise head and the tail each 2 anchor, for the windlass of folding and unfolding anchor and the all-direction propeller for barge dynamic positioning, stem anchor 1,2 and the afterbody anchor 3,4 of stem windlass 5,6 and afterbody windlass 7,8 and correspondence are all symmetrically arranged along ship center line, stem windlass 5,6 place arranges an all-direction propeller 9, and afterbody windlass 7,8 place's correspondence arranges two all-direction propellers 10,11.
Above-mentioned windlass is single drum winder, and pulling force of weighing anchor is 20 tons, and maximum load can reach 40 tons.
Anchor is mainly used in grappling accommodation, windlass by anchor hawser realize weigh anchor with cast anchor wait operation, propelling unit be used for navigation and adjust accommodation.Of the present utility model from casting anchor system, be applicable to the Multifunction well-repairing platform carrying propelling unit of sheltered waters, utilize head and the tail 4 windlass to position anchor work, after the anchor that falls, form 4 constraints, and in conjunction with dynamic positioning system (DPS), fixation is formed to well workover position.
Workover platform moves at different oil gas setting, and after arriving at setting, platform can rely on engine installation to carry out dynamic positioning, and keeps berth.First, the work of bow portion windlass 5, stem windlass 6 is carried out putting anchor, and platform carries out reversing operation, and backward to certain distance carries out afterbody windlass 7, afterbody windlass 8 falls anchor operation.Regulated by the length of winch to anchor chain after 4 anchors that fall, adjust the float position of platform with this.During carrying out winch operation, constantly utilize thrust power position fixing system to adjust in the lump, shorten the positioning action time.
Until adjust complete after, utilize the chain controller on windlass (winch) to be locked by anchor chain, complete whole platform location, fixing process thus.
For of short duration remedial work, barge can realize the function of barge dynamic positioning by self three all-direction propeller 9,10,11 and autonomous cruise speed system.
For the remedial work of long period, barge navigates by water object well head region, utilizing the propulsion system of self to be adjusted to barge position casts anchor a little, release anchor hawser, when anchor hawser is lax, barge is adjusted to the final position of well workover point, tightens up four anchor hawsers, thus reaches the object from location of casting anchor.
Claims (2)
1. workover platform is from casting anchor system, it is characterized in that: this certainly the system of casting anchor comprise head and the tail each 2 anchor, for the windlass of folding and unfolding anchor and the all-direction propeller for barge dynamic positioning, stem anchor (1,2) and the afterbody anchor (3,4) of stem windlass (5,6) and afterbody windlass (7,8) and correspondence are all symmetrically arranged along ship center line, described stem windlass (5,6) place arranges an all-direction propeller (9), and described afterbody windlass (7,8) place's correspondence arranges two all-direction propellers (10,11).
2. workover platform according to claim 1 is from casting anchor system, it is characterized in that: described stem windlass (5,6) and afterbody windlass (7,8) are single drum winder.
