Answers for energy.Sustainable profit Offshore wind power – firmly established as a viable source of renewable energyDue to higher, more consistent wind speeds at sea, offshore wind turbines can generate substantially more energy than onshore wind turbines. Offshore wind farms may reach capacity factors in the range of 50%. Even considering the planning constraints relating to shipping lanes, fishing, bird migration, and the like, the world has abundant space for offshore projects.Offshore wind power has its challenges, however. Conditions during installation, operation, and maintenance may be harsh, and the product requirements are high. It takes a special supplier to provide stable, long-term offshore partnerships.When it comes to offshore wind power, no supplier can match Siemens in terms of experience and reliability. Siemens has a proven track record for delivering offshore projects on budget. From the world’s first offshore wind farm almost 20 years ago to today’s largest offshore wind farms, all projects have been deliv-ered on time and on budget. All projects operate with high availability. Optimized processes across the complete project life cycle make Siemens a stable, reliable, and trustworthy business partner.Number one in offshore Grown from experience Siemens has developed a broad realm of experience and excellent skills in deliver-ing offshore projects.From the outset Siemens has played a key role in founding the offshore wind industry by installing the world’s first offshore wind farm in Vindeby, Denmark, in 1991. The 11 turbines installed in this pioneering project are still in excellent condition. The turbines have consistently operated at high availability, reflecting the unique combination of product quali-ty and dedicated offshore modifications. Now, amidst the current boom in off-shore projects, Siemens still leads the world in offshore technology. With an installed offshore capacity of more than 600 MW and a high order intake, the company remains the preferred supplier of wind turbines to offshore projects. Furthermore, unlike any other offshore wind turbine supplier, Siemens offers equipment for the entire energy value chain, from the wind turbine to net conversion, efficient feed-in to smart energy grids, and power distribution.Siemens offers integrated solutions and services that perfectly meet the high demands along the entire wind energy conversion chain4Making history, over and over againThe trend in offshore wind farms is towards larger and more complex proj-ects, located further from shore, in deeper waters, which are exposed to severe sea and wind conditions.Utilizing the knowledge gained from almost two decades of experience in the offshore environment, Siemens is equipped to handle the challenges of this unique environment.Siemens has not only supplied the world’s first, but also the world’s largest offshore projects. For several years, the 165-MW Nysted offshore wind farm held the record as the largest offshore project. In September 2009, that record will be broken by the 200-MW Horns Rev II project. The 500-MW Greater Gabbard project, currently under instal l ation, will raise the bar again. And the world’s first 1-GW project, London Array, will represent yet another stride towards large-scale, green energy supply.All record projects – and all feature Siemens wind turbines.Providing the best technologyWhen access conditions are difficultand when high wind resources makeevery hour count, reliability is the keyto profitability.Over the years, Siemens turbines haveset the standard for robustness andre l iability. Designed with offshore appli-cations in mind, the turbines have arugged, conservative structural design,automatic lubrication systems with amplesupplies, climate control of the internalenvironment, and a simple generatorsystem without slip rings. These andmany other high-quality design featuresprovide exceptional reliability with longservice intervals.Siemens turbines are built to last. Delivering on a promiseDelivering projects on time and withinbudget is one of Siemens’ majorstrengths. Since the offshore industrywas established in 1991, and despitethe logistical challenges associated withoffshore installation works, everySiemens offshore project has beencompleted within budget and on time.This unique track record was not estab-lished by chance. It requires deep respectfor the challenging conditions, detailedplanning, and superior and consistentproject management skills requiredduring the execution phase. All of whichare key elements of the Siemens offshoremodel.The Siemens offshore model has beenproven to deliver results. Everywhere,every time.Siemens can also supply turnkey grid connectionsfor wind farms, including construction of theoffshore transformer station5Maximized potential across the boardA well-proven and robust installation processPre-assembly of components Once all necessary compo- n ents have been delivered, pre -assembly commences. Siemens designs, plans, and executes all work processes to minimize the amount of work required offshore.Components delivery to port Siemens transports all compo-nents, parts and equipment to a harbor site close to the pro-posed wind farm. The site serves as the assembly and embarka-tion station for the project.Storage of rotor bladesSpecialists place rotor blades in the storage area, ready for shipment to the site. The blades are stored in special transport fixtures used on the installation vessel. In some cases, blades are shipped as completed rotors.Load outService technicians load allcomponents onto the transport vessel in accordance with the project plan. Siemens’ proprie-tary fixtures and sea fastenings are used for safe transport andworking procedures.6Experience counts in installation Drawing on almost two decades of expe-rience in successfully delivering offshore projects on time and within budget, Siemens knows exactly what it takes. Over the years, a large number of aspects of installation methodology have been tested and analyzed. Gradually, best practices have been established, and even though the process often needs to be adjusted to fit project-specific re q uirements, the fundamental approach remains the same.Installation scopeThe Siemens installation scope istailored to the needs of individual cus-tomers. One classical approach is an all-in equipment supply where Siemens provides the installation vessels. In an-other approach, the customer provides the installation vessels and Siemenscarries out the work. Further alternatives are possible, depending on the custom-er’s skills and objectives and a joint evalu-ation of the most optimal solutions. Irrespective of the installation scope, Siemens’ customers will always benefit from the reliability and robustness of a proven installation process.TransportA transportation vessel takes the components to the site. Transportation time can vary from site to site based on many factors, including the vessel type, the distance from the port of origin to the site, and weather conditions.InstallationThe transport vessel arrives on- site. The tower is lifted onto the foundation. Service technicians then lift the nacelle onto the tower and the rotor is mounted on the nacelle, either as a com-pleted unit or in single-blade installation.CommissioningOnce the turbine is mechanically completed and energized, it is thoroughly tested for commis-sioning. Some tests are auto m at-ically performed by the turbine computer controller, while others are performed by the service crew.Service and maintenance Siemens provides service and maintenance during the warran-ty period. Long-term service and maintenance contracts are also available from Siemens to ensureyears of trouble-free operation.By thoroughly understanding the com-plexity and challenges associated with implementing an offshore project, and by establishing optimized installation processes, Siemens maximizes the value of each link in the chain, providing mini-mum costs and optimum predictability in project delivery.7Simply the bestThe fundamental pillars –the best turbines and the best serviceThe blades are mounted on double-row pitch bearings fitted to a large rotor hub. The pitch actuation system is hydraulic, offering maximum robustness and safety. Like the turbine itself, the blades are designed to last.NacelleThe nacelles of the Siemens’ offshore turbine types are ideally suited for severe offshore operating conditions.Major components such as the main shaft, the gearbox, and the yaw system are all of particularly heavy dimensions. The automatic lubrication systems have redundant lubricant reserves to enable continued operation even if scheduled maintenance is severely delayed by weather. The nacelle canopy is metallic to provide optimum lightning and fire protection. All safety systems are fail-safe and have layers of redundancy. Fully integrated climate control and compre-hensive offshore-grade surface protec-tion contribute to long service life. Overall performance is well-proven and all details are designed using market-leading engineering practices.TowerSiemens offshore turbines are normally mounted on tubular steel towers fitted with internal personnel hoists.A prefabricated power module is located at the bottom of the tower and provides the platform for the power converter, the turbine transformer, and the medium-voltage switchgear.Turbine types offeredTwo Siemens turbine types are offeredfor offshore projects, the SWT-2.3 andthe SWT-3.6. Both types offer the samekey features.RotorThe rotor blades for Siemens’ offshoreturbines are made of fiberglass-reinforcedepoxy, manufactured using the proprie-tary Siemens IntegralBlade® process.Unlike conventional wind turbine blades,the IntegralBlades® are cast in one piecein a closed process. This process leavesno weak points at glue joints and pro-vides optimum quality. The aerodynamicdesign represents state-of-the-art windturbine technology, offering maximumenergy extraction from any availablewind resource, and the structural designlives up to the usual Siemens safetyfactors in addition to all industry codesand standards.Blades on a service vessel before mounting The inside of an SWT-3.6 8Service and maintenanceReliable and competent service and main-tenance is almost as important for profit-able offshore wind power projects as selecting the right turbine equipment. Due to sea and wind conditions, access may be restricted for long periods, and the losses resulting from trivial errors could be substantial.Siemens is known as the most experi-enced and reliable offshore service pro-vider, with an unmatched track record for maintaining optimum availability. Central demand planning, excellent diag-nostics capabilities, and competent field service teams offer fast response times and well-planned service operations.The service offering can be adjusted to match the owner’s skill sets, objectives, and interest in participation. Irrespective of the service scope, Siemens’ support enables owners to maximize revenue and earnings throughout the project lifetime.MonitoringSiemens offshore turbines are equipped with the unique Siemens WebWPS SCADA system. This system offers remote control and a variety of status views and useful reports from a standard Internet browser. The status views present information such as electrical and mechanical data, operation and fault status, meteorologi-cal data, and grid station data.Voltage and frequency control, and other grid-related adjustments, can be imple-mented by the integrated park pilot utility in the WebWPS SCADA system.In addition to this WebWPS SCADA system, the turbine is equipped witha web-based turbine condition monitor-ing (TCM®) system. The TCM® system con t inuously carries out precise condition diagnostics on main turbine components and gives early warning of possible com-ponent problems in real time. Basedon the TCM® system, Siemens can detect and correct any problems at the earliest possible stage, thereby reducing mainte-nance costs, optimizing availability, and maximizing energy output.Grid performanceGrid stability requirements grow as morewind power is fed into the grid. Siemensalso sets the standard in the field of gridcompliance.Power conversion is implemented withSiemens’ unique NetConverter® system.This system uses full conversion of thepower generated, efficiently decouplinggenerator and turbine dynamics fromthe grid. The NetConverter® systemoffers maximum flexibility in the turbineresponse to voltage and frequency con-trol, fault ride-through, and output ad-justment. As a result, Siemens turbinescomply with all relevant grid codes.Blades being transported before mounting Service technicians at work on an SWT-2.3-939World’s first offshore wind farmSiemens was the first wind turbinemanufacturer to venture out to sea.In 1991, 11 turbines of 450 kW wereinstalled at Vindeby, off the southernislands of Denmark.The turbines, which are still runningefficiently today, gave Siemens a headstart in offshore projects and provideda testing ground for offshore modifica-tions. These modifications are nowthoroughly proven and form the basisof today’s turbine technology.The mega farms of tomorrow havetheir roots in this humble installation.Offshore wind turbines are growingNot only are offshore wind farms in-creasing in size, but so is the equipment.In 2004, Siemens introduced theSWT-3.6-107 turbine type. Eight timeslarger than the first offshore turbines,the 3.6-MW turbine type is now consid-ered the de facto standard for offshoreprojects.In 2007, the first 25 SWT-3.6-107 windturbines were installed at Burbo Banks.Published by and copyright © 2009: Siemens AGEnergy SectorFreyeslebenstrasse 191058 Erlangen, GermanySiemens Wind Power A/SBorupvej 167330 Brande, Denmark/windFor more information, please contactour Customer Support Center.Phone: +49 180 524 70 00Fax: +49 180 524 24 71(Charges depending on provider)E-mail: support.energy@ Renewable Energy DivisionOrder No. E50001-W310-A118-X-4A00 Printed in GermanyDispo 34804, c4bs No. 7491fb 1829 WS 09092.5Printed on elementary chlorine-freebleached paper.All rights reserved.Trademarks mentioned in this documentare the property of Siemens AG, its affiliates,or their respective owners.Subject to change without prior notice.The information in this document contains general descriptions of the technical options available, which may not apply in all cases.

在灌浆之前提前6~12小时洒水至湿润状态。
(2)灌浆浇筑按照风机厂家的要求,在高强螺栓之间按照一定的间距放入金属板、纤维板及垫片,并对垫片进行调平,要求任意两个垫片之间水平度在±0.5mm。
垫片调整后应根据灌浆材料初凝时间,至少3小时后(在10~15℃)方可吊装底节塔筒。
(3)吊装底节塔筒后,应在塔筒内外小心安装高度约80mm的模板,使其保持垂直,然后固定到混凝土上,从外面堵住所有模板裂缝和连接处。
(4)灌浆之前应对底节塔筒进行调平观测,塔筒垂直度满足风机厂家的要求。
(5)灌浆从底节塔筒外侧采用人工浇筑灌浆,同时底节塔筒内侧安排人员进行控制,浇筑应多点同时进行,灌浆过程中不应出现中断,按灌浆材料厂家要求进行灌浆。
(6)灌浆完毕后,要求外露灌浆面平整水平度在±0.5mm,要求均匀分布在底法兰上的六个观测点水平度在±1.0mm。
(7)灌浆结束后,应当在5天时间内对外露区进行相应的保护措施,以防止风吹、气流和过早蒸发。
(8)灌浆获得足够强度后才可以拆除模板,然后对结合处进行表面检查,以确定是否存在空洞和缝隙,如果存在应与各方协商解决。
(9)在灌浆后,至少进行5天养护后才可以张拉预埋螺栓,7天后才能吊装塔筒。
