Abstract
The invention discloses a process for lifting an offshore booster station jacket in shallow water; the process comprises the steps of (1) positioning when a lifting ship is in floating state; (2) pre-leveling; (3) numbering; (4) lifting a jacket; (5) leveling the jacket, welding, and grouting. An offshore booster station of a marine wind farm can be well installed in shallow water, the large-scale marine wind powder is guided, and the process has high popularization value.
Description
Technical field
The present invention relates to offshore booster station structure mounting technique field, more particularly to a kind of phytal zone offshore boosting station conduit
Frame hoisting.
Background technology
Huge consumption and the severe contamination of environment with fossil energy, regenerative resource is more and more subject to the world each
The concern of state, wind energy becomes most one of new forms of energy of competitiveness.Land wind-powered electricity generation is compared, offshore wind farm is not only not take up soil money
Source, and energy enrich, stable, utilization rate of exerting oneself it is high, it has also become the new direction of world's Wind Power Development.From the sea of current planning
From the point of view of Wind Power Project, wind energy turbine set offshore distance all in more than 10km, need build offshore boosting station, by voltage lifting after, pass through
High-voltage undersea cable is delivered to continental Grid.
But marine wind electric field booster stations need to install jacket as supporting construction, and traditional method is pacified using large-scale floating crane
Dress, but large-scale floating crane drinking water is deep, it is impossible to ' s operation in shallow water is entered, thus is difficult to that marine liter is installed in phytal zone using conventional method
Pressure station jacket, need to for shallow sea water the characteristics of, using shallower draft can the pontoon barge on seat beach installed.But marine operating mode
Badly, condition is poor, very high to pontoon barge installation requirement,
Accordingly, it is desirable to provide a kind of phytal zone offshore boosting station jacket hoisting is solving the above problems.
The content of the invention
In order to solve the problem, the invention discloses a kind of phytal zone offshore boosting station jacket hoisting, its mesh
Be exploitation offshore boosting station jacket installation new technology, in phytal zone pontoon barge at sea complete booster stations jacket peace
Dress, the solution booster stations phytal zone depth of water is shallower, and the drinking water of large-tonnage crane barge ship is deep to be cannot be introduced into, and by the little crane barge of shallow draft peace is completed
Dress, install convenient, simple, efficiency high, expense are low, operational security is good.A kind of phytal zone offshore boosting station jacket slinger
Skill, the technique comprises the steps：(1) -- (2) pre-leveling -- (3) number -- (4) jacket is positioned when lifting method of ship floating condition
Lifting -- (5) jacket leveling, welding and grouting；
(1) position when lifting method of ship floating condition：Position during lifting method of ship floating condition, lift when sitting beach, jacket cargo ship is in place
In lift-on and lift-off ship side；
(2) pre-leveling：Steel pipe pile bracket pad pre-leveling；
(3) number：Pile sinking figure is numbered with field conduit frame；
(4) jacket lifting：Hoisting rig is got out, and checks its integrity, two strands are arranged on lifting machine platform
Car, as cable wind system during lifting, after hanging up properly hoisting rig, removes all colligation frocks on deck, leaves in jacket
During more than ship board face 4m, lift-on and lift-off ship plays large arm and returns and goes to seat in the plane center top, slowly puts into jacket
On foundation pile；
(5) jacket leveling, welding and grouting：After the completion of jacket lifting, level is adopted in jacket temporary platform
Instrument measures each column elevation of jacket and levelness whether in the range of design code.Then carried out using hydraulic jack micro-
Leveling, flatness meets the welding that limit plate is carried out after requirement, finally carries out grouting process, carries out after intensity meets requirement
The lifting of portion's chunk.
Beneficial effects of the present invention are：
The present invention solves install marine wind electric field offshore type booster stations in phytal zone very well, is that offshore wind farm is built on a large scale
If guidance is provided, with stronger promotional value.
With reference to advantages and features of the invention described further below.
