Description

Semi-submersible type deep-sea wind-powered electricity generation mounting platform and its wind power generating set integral installation method
Technical field
The invention belongs to deep-sea offshore platform structure design field, and in particular to a kind of deep-sea semi-submersible type wind-powered electricity generation transport is installed Unified platform and its wind-driven generator installation method.
Background technology
Wind-power electricity generation is green energy resource technology with fastest developing speed in the world.Offshore wind farm is the forward position of wind power technology, is also The major fields of international Wind Power Generation Industry development.Generally speaking, offshore wind farm is still in the early stage of development, the blower fan unit of current main flow Form, divides according to base form and is broadly divided into following a few major classes:Gravity type foundation, single pile type foundation, tripod type basis, lead Pipe-support type is basic, many pile type foundations, cylindrical foundation and floatation type basis etc..The utilization of offshore wind farm in recent years is generally concentrated at closely Marine site, with the exploitation of near-coastal resources, the region of offshore waters and environment are limited, and offshore wind farm will certainly be toward deep-sea development. And shallow sea cannot meet the requirement of ocean petroleum developing using the wind energy conversion systems such as more pile foundation type basis, and offshore wind turbine is due to cost The trend of maximization, floatation type basis is suitable for.By fixed base growth be floatation type basis also turn into development trend it One.
Offshore wind farm units' installation is provided with technical difficulty higher relative to land Wind turbines, is that marine wind electric field is built If one of key technology.Completing lifting needs an Attention problems job platform.Mainly have:Large-scale crane ship, jack up are (non- From boat) platform, band positioning spud leg self-propelled ship, from navigate jack up installation ship.Main ship type is installed according to current wind-powered electricity generation to compare, As shown in table 1, the trend drive on boldly to deep-sea to solve offshore wind turbine in future to maximize, semi-submersible type wind turbine installation vessel has sea-keeping The features such as deep, the suitable blower fan whole Transporting of good, operating water depth is installed, one of market trend is installed in following deep-sea wind-powered electricity generation.
Research shows that the wind energy content of whole world major part marine site unit area belongs to wind energy money in 2 × 103 (kW.h)/m2 The enrichment region in source.It is estimated that whole world sea depth 60-900m regions Wind turbines installed capacity is about 17.4 × 108kW, therefore deep-sea Wind-power electricity generation has a high potential.Due to deep-sea awful weather, effective operation time is short, so units' installation is whole marine wind electric field The link of difficulty of construction highest and greatest risk in process of construction, directly determines the success or failure of whole project.Units' installation technology Including two parts of mounting platform and mounting means.The transport of current major part offshore wind farm unit, lifting, the main support of maintenance Carried out in existing ship platform.Such as traditional crane ship (non-from rising from boat), lifting mounting platform (non-from navigating from rising) and from navigating From the type of liter crane ship 3.Existing mounting technique certainly will can not meet new environmental requirement.Semi-submersible type wind turbine installation vessel has The features such as sea-keeping is good, operating water depth is deep, suitable blower fan whole Transporting is installed, floatation type basis, integral installation and deep-sea are installed Platform very likely turns into the mainstream technology of following Oversea wind power generation.
The wind-powered electricity generation of table 1 installs main ship type
Accordingly, it would be desirable to design the deep-sea for meeting the basic Apparatus whole Transporting of floatation type, installing integrated semisubmersible platform Semi-submersible type windmill mounting platform, to solve the problems, such as the windmill transport on deep-sea floatation type basis and install, solves sea turn in future Machine maximizes the trend drive on boldly to deep-sea.
