Description
Technical field
The present invention relates to Naval Architecture and Ocean Engineering field more particularly to a kind of shallow draft Spar suitable for middle coastal waters domain
Basis.
Background technique
Compared with landwid electric field construction, marine wind electric field will be in face of the test of the multiple load such as stormy waves stream, environmental condition
More complicated, technological development difficulty is bigger, and facing need to be to new challenge.Currently, intertidal zone, subtidal zone mudflat wind electric field and coastal waters
Wind power plant, marine wind electric field of these depth of waters no more than 50 meters generally use fixed foundation structure form, mainly include gravity
Formula basis, single pile or more pile foundations etc..
2011, National Energy Board combines with National Bureau of Oceanography to formulate and has put into effect that " offshore wind power development implementation management is temporary
Row method detailed rules for the implementation ", according to the detailed rules and regulations, marine wind electric field should be no less than 10 kilometers, beach width in offshore distance in principle
The sea area that the sea area depth of water must not be less than 10 meters when more than 10 kilometers is laid out, it is seen then that the following offshore wind farm developing direction is far from bank
The deep-sea on side is developed.In the blue water far from continent, the wind-resources that can be developed and used are more more high-quality, and market prospects are also wider
It is wealthy.The wind power plant that these depth of waters are more than 50 meters is developed, is generallyd use according to current offshore wind farms various through pilework
The way for being fixed on seabed will provide no advantage against, and be mainly manifested in:
1, it is restricted using the offshore wind turbine addressing on fixed basis.Since coastal functional area planning is intensive, offshore wind farm
Often with fishery, army area under control, environment protection zone, port boat Channel contention, this brings very big to offshore wind farms addressing for field addressing
Difficulty.And deep-sea wind farm siting can effectively avoid these functional areas, wind farm siting since offshore is apart from relatively far away from
Freedom degree is bigger.
2, with the increase of the depth of water, the cost on fixed basis is ramped.With the increase of sea area depth, fixed base
The steel using amount of plinth and construction and installation cost can proportionally increase, and overall cost will be apparently higher than floating type wind power generation
Machine.The construction on known traditional fixed basis and installation cost are directly proportional to the depth of water, and the construction and installation on floatation type basis
Cost is insensitive to the depth of water.Fixed basis and the cost watershed of floatation type basis the two are in 50 meters of depth of water or so, if water
Deep to be greater than 50 meters, then the cost on fixed basis will be much higher than the cost on floatation type basis.
3, fixed offshore blower construction cost is higher than floatation type offshore wind turbine construction cost.Reduce offshore wind power development
Cost needs to consider two very crucial factors.One is that large-scale floating crane or other large size installation equipment are used with caution, another
It is to try to prevent the replacement of big component.Reducing using large-scale floating crane is a sea because the use cost of large-scale floating crane is quite high
If upper wind power plant is excessively frequent using crane barge ship, it will cause entire wind power plant construction costs to be significantly increased；And big component
Replacement, first is that needing Large Construction ship, in addition shutting down the big component of replacement also will affect gene-ration revenue.Using conventional fixed-type base
The blower of plinth is difficult to evade both of these problems, and both of these problems are also the high important original of offshore wind farms development cost
Cause.And both of these problems can be well solved using floatation type basis.The installation method and conventional fixed-type of floatation type blower
The installation method of blower is entirely different.First can be good by foundation construction in harbour or dock, then itself and blower is whole
It is assembled good, target sea area then, which is dragged to, entirely through towboat casts anchor positioning.Entire work progress does not need any large ship, greatly
Construction cost is reduced greatly.In addition, encountering the replacement of big component, it can also be dragged in dock and be overhauled with take-up, operation expense
It also will be greatly reduced relative to fixed blower.
It based on factors above, needs to research and develop a kind of economical and practical floatation type blower, base is installed in sea bed bottom to overcome
The shortcomings that plinth structural cost is by water depth effect develops the construction of marine wind electric field to more deep-sea domain, makes full use of China
Wide marine wind energy resource.And how the field of wind-force in coastal waters domain efficiently uses in there are problems that now: the depth of water is less than 50 meters
Greater coasting area, construction and economy are easy for using gravity type foundation and single, more pile foundations, are more than 100 meters of sea in the depth of water
Domain is using floatation type basis, such as semi-submersible type, Spar formula, tension leg type be all it is more economical compared to fixed, be suitable for deep-sea
Sea situation.And in middle coastal waters domain, 50 to 100 meters of field of wind-force does not have a kind of generally acknowledged preferable base application in this.Therefore, ability
The technical staff in domain, which is dedicated to developing one kind coastal waters domain suitable for 100-200 meters, can provide wind-driven generator normal operation needs
