Advanced condition monitoring systems full prognostic and diagnostic capability先进的状态监测系统,全面预测与诊断能力
• Therefore, access is important and the potential saving are driving innovation from industry
因此, 进入性至关重要,因为它将能带来更多的发电,因此将推动行业技术创新
Access – The Pinch Point is Getting On! 进入 – 关键是如何登上作业平台
The ‘Old’ Way
以前的方式The New Way 新方式
• It’s not about getting there, it’s about getting on! 到达并不难,关键在于如何安全的登上塔架。
• Safety requirements paramount - must be ‘happy to climb’ 安全要求的第一保证 - 快乐着攀爬
• Significant wave height capability of the step-off platform is the limiting factor 跃上平台海浪高度是的一个限制因素

Getting to Site – The ‘Old’ Way 进入现场 – 以前的工作方式
• Aluminium catamaran work-boats, typically 12-16m LOA 铝制双体工作船,船舶总长 12-16 米
• Max 12 technician crew + 2/3 vessel crew 最多 12 个技术人员, 2 或 3 个船员• Significant wave-height capability of 1.2 to 1.5m 承受最大浪高 1.2 至 1.5 米• OK for near-shore sites, no good for rough ones 适用于近海区域海平面较平静处
Getting to Site – The Latest Workboats进入现场——最新式的工作船
• Bigger, faster, better equipped, more foredeck, 20-24m LOA 更大,更快,设备更精良,更多前甲板,全长 20-24 米
• Still max 12 technician crew + 2/3 vessel crew 最多 12 个技术人员, 2-3 个船员• Significant wave-height capability of 1.5 to 1.7m 承受最大浪高 1.5-1.7 米• Excellent for near-shore sites, still not brilliant for rough ones 非常适合近海区域,
但对于不平静的海面情况并不理想
Getting to Site – The Expensive Alternative 进入现场——昂贵的选择
• Pros: independent of wave-height, very fast response 优点:不受海浪制约,相应速度快
• Cons: expensive, limited capacity, consequence of failure 缺点:昂贵,载力有限,一旦失败产生的后果
• For some projects is the default access method 一些项目,是默认的方式• For newer projects is only the rescue, mission critical option 新项目,只用
于救援或特殊使命
Getting to Site – Beyond Workboats (1)进入现场——超越工作船( 1 )
• 24 or more technician crew + 3/4 vessel crew, MCA coded 24 或更多的技术人员,加上 3 至 4 名船员, 英国船舶检验局技术规范
• Significant wave-height capability of 2.0 to 2.5m 可驾驭浪高 2 至 2.5 米• Good for rough sites – but slower and more expensive to run 可用于不平静
的场址,但昂贵且速度慢
Getting to Site – Beyond Workboats (2)进入现场——超越工作船( 2 )
• Bigger monohulls, tri-marans, ‘System Carriers’, 30-50m OAL 更大的单体船,系统携带者, 30 至 50 米长• Max 24-60 technician crew + 4/5 vessel crew 24 至 60名技术人员, 4至 5 名船员• Significant wave-height capability of 2.0 to 2.7m, more with system 支持浪高 2 至 2.7 米• Very expensive, best for rough unoccupied sites 非常昂贵,但很适用于粗糙的闲置区域
Access Systems – Vessel Add-Ons进入系统——船只附加装置
• Technician step-off platform is no longer the vessel itself 工作人员的舷梯平台已经不再是船只本身
• Active or passive motion compensation, ‘walk to work’ 积极或消极的动作补偿,步行去工作
• Significant wave-height capability of 2.5 to 3.0m, vessel dependent 支持浪高, 2.5 至 3 米,取决于船只
• Very expensive, best for routinely rough sites 非常昂贵,适合于粗糙场地的日常巡检
Staying at Site – In-field Accom and OSVs停留在现场——现场住所和海上服务船
• Accommodation platform – stable & comfortable, but HV concerns住所平台——稳固且舒适,但高压电值得关注
• Offshore Service Vessel – mother ship and daughter craft concept 海上服务船——母船与子吊车概念
• Both still require transfer to the WTG 都需要运送到风机• High cost means large wind farms only, or clusters 高额费用意味着只适用于
大型风电场,或风电场群
Staying at Site – Floating Hotel Workshop停留在现场——浮动酒店工作室
• The vessel goes WTG to WTG, DP2 positioning + Access System 船只需要从一个风机去另一个风机,需要配备动态定位 II 以及进入系统
• System, helicopter and daughter craft capability all-in-one 系统,直升机和子吊车多合一
• Minimal or no ladder climbing for the technicians, maximum safety 近乎无攀爬工作,最大的安全性
• Expensive, but is it’s own support vessel 昂贵,但是完全自主的• Not tested at scale yet – Vestas and Siemens will be the first 尚未测试过——维斯塔斯和西门子将是尝试者
Clearly a trend towards floating structures浮式结构是明显的趋势
Specialist Vessel Design (Maintenance Vessel
Concept)
专用船只设计(维护船概念)
Floating Offshore Substations or
Accommodation
浮式海上升压站,住所
Offshore Met Data
Collection Buoy
海上测风浮筒
Siemens – Centrica Lincs Subs Stataon
Conclusions 结论• Prevention is better than cure – fully characterise the sites! 防患于未然 ——
全面了解场址情况• The technology exists to: 技术应用
– Assess turbine performance and response to wind flow 评估风机表现以及对气流的反应
– Identify and act on operational anomalies 确认运行中的问题并采取行动– Optimise operations and maintenance to maximise production and
profit 优化运维以最大化产量及利润• It new needs to be packaged into a Total Asset Management offering 提供整个资产管理捆绑服务是新的需求
• The market is responding to the access needs of the offshore wind market and is being driven by the scale of UK & European developments 市场受制于海上风电市场可进入性需求,驱动于英国和欧洲的开发规模
• Solutions will be project-specific from a short list of suitable options 一系列的方案可供选择,但将取决于项目特性
• The future will see larger, faster and more stable support vessels and a trend towards floating structures 未来将看到更大,更快,更稳固的运输船作为辅助,并且浮式结构也将是未来的趋势
