Description
Technical field
This utility model is related to a kind of platform supply vessel mooring gear.
Background technology
Self-elevating drilling platform is made up of platform, spud leg and elevating mechanism, and platform can be lifted along spud leg, general without from boat energy
Power.Spud leg decentralization insertion seabed during work, platform are raised to the trouble free service height for leaving sea, and spud leg are carried out pre-
Pressure, will not be sunk with spud leg when ensureing that platform runs into storm.Completion rear platform drops to sea, extracts spud leg and all lifts, whole
Individual platform floats on sea, is dragged to new well location by tugboat.Nineteen fifty-three, the U.S. built up First jack-up unit, and this platform is to water
Deep strong adaptability, job stability are good, and development is very fast, account for the 1/2 of portable drilling rig sum.What China voluntarily manufactured
Four pile lower limbs of self-elevating drilling platform " Bohai Sea one " platform are made by circular steel pipe, and the height of spud leg has more than 70
Rice, lowering or hoisting gear is bolt-type hydraulic control.The type drilling platforms cost is relatively low, migration property is good, sea-floor relief is fitted
Ying Xingqiang, thus, using self-elevating drilling platform Chinese offshore drilling more.
Semisubmersible drilling platform is developed by bottom-supported platform, and top is spar deck, and bottom is two pontoons, is used
Support post connects.During work, pontoon pulls the plug, and in water safety height, Area of Water Plan is little, and wave effect is little on deck,
Good stability, self control ability are strong, operating depth is big, and after the dynamic positioning technology of new development is used for semisubmersible platform, operating depth can
Up to 900-1200 rice.Compared with self-elevating drilling platform, advantage is that operating depth is big to semi-submersible type, mobile flexible；Have the disadvantage investment
Greatly, standing charges are high, and the utensil under water that need to have a set of complexity, availability are less than self-elevating drilling platform.
Deep water semi-submersible drilling platform and self-elevating drilling platform, are all offshore drillng operations, oil, water on platform,
Drilling fluid dispensing and living material etc. are fed all by platform supply vessel.But, platform supply vessel is to platform
When being fed, need relative position to be kept with drilling platforms, and ocean current, wave can cause supply vessel away from platform, to mending
Impact to work.Generally, platform supply vessel can keep accommodation using its dynamic positioning system for carrying, but, power is fixed
The unlatching of position system, will greatly increase the fuel consumption of supply vessel, so as to increase cost payout.Therefore, if can be on platform
Side is installed by a set of mooring gear for both fixed drilling platform and platform supply vessel position, it is ensured that supply work, will very
Be conducive to production practices.
Utility model content
The technical problems to be solved in the utility model lack between the drilling platforms of prior art and supply vessel to be overcome
The device of both weary fixation relative positions, and the defect of the dynamic positioning system of supply vessel is must be turned on, and provide a kind of brill
Well platform supply vessel mooring gear.The platform supply vessel mooring gear that this utility model is provided has simple structure, Yi Shi
The advantages of existing, easy to operate, performance is good, it is adaptable to all offshore drilling platformses.
This utility model is solving above-mentioned technical problem by following technical proposals：
This utility model provides a kind of platform supply vessel mooring gear, and which includes two groups of attachment structure units, often
Attachment structure unit described in one includes a mooring eye plate, a mooring cable and a connection piece being sequentially connected, the mooring eye plate
The side of drilling platforms is fixedly welded on, the connector is used to realize the connection between the mooring cable and supply vessel.
It is preferred that the connector is a joining shackle.
It is preferred that the mooring eye plate in two groups of described attachment structure units is connected to the two sides of drilling platforms.
It is preferred that the connector in two groups of described attachment structure units is connected to the two ends of the stern of supply vessel.
It is preferred that when drilling platforms is semisubmersible drilling platform, described mooring eye plate is fixedly welded on the partly latent
On the pillar construction of formula drilling platforms.
It is preferred that when drilling platforms is self-elevating drilling platform, described mooring eye plate is fixedly welded on described from liter
On the ship side structure of formula drilling platforms.
When using platform supply vessel mooring gear of the present utility model, it is preferred that according to ocean current, the reality of wave
Situation, selects supply vessel in drilling platforms dorsad ocean current side, while the stern direction of supply vessel is adjusted to putting down near drilling well
The side of platform, and fore direction is adjusted away from the side of drilling platforms.
Positive effect of the present utility model is：The platform supply vessel mooring gear that this utility model is provided leads to
Cross mooring gear to connect drilling platforms and supply vessel, it is ensured that supply is smoothly completed；Avoid the power using supply vessel fixed simultaneously
Position system, substantially reduces cost.
