離岸風電計畫運輸與安裝(T&I)服務規劃解析|風險管理與臺灣案例分析

更新 發佈閱讀 9 分鐘

台灣離岸風電的裝置容量已領先許多亞洲國家,近期韓國與日本多家廠商來台取經。茲整理離岸風電運輸與安裝(T&I)規劃重點,供各位參考。最後,還附上台灣經驗供大家參考。首先,是離岸風電全壽期的時程:

T&I Planning Workflow

A. Preliminary Phase

•Site Assessment: Metocean, bathymetry, seabed conditions

•Feasibility Study: Conceptual logistics, access windows, weather constraints

•Interface Planning: Coordination with design, fabrication, and commissioning teams

B. Logistics & Marine Strategy

•Vessel Selection: WTIVs, HLVs, AHTS, CTVs, barges, cable-lay vessels, etc.

•Port and Base Planning: Staging ports, pre-assembly, load-out sequences

•Transit Routes: Risk assessment for marine routes and landfall access

C. Detailed Planning

•Installation Sequences:

•Foundations first → cables → offshore substations → turbines

•Weather Windows: Planning suitable periods for lifts and seabed work

•Lift Plans & Marine Procedures: For each component

•Simulations: Time-motion studies, risk scenarios

D. Project Execution Plan

•Schedules: Gantt charts, critical path analysis

•Contingency Plans: For delays due to weather, equipment, or interfaces

•Permits & Certifications: Navigation, environmental, work permits

Key Considerations in OWF T&I

Category Key Elements

Weather Risk Wave height, wind speed, current, sea state

Vessel Limitations Deck space, crane capacity, jacking capability, DP classification

Port Infrastructure Quay strength, RoRo access, craneage, storage

Seabed Conditions Soil type, boulders, cable burial depth

HSE & Regulation Safety protocols, marine warranty surveyor (MWS) requirements

Interface Management Fabrication yards, logistics, commissioning team


Deliverables in OWF T&I Planning

Example Vessel Deployment Plan (Simplified)

Phase and Vessel Type

Foundation: HLV/Barge/AHTS

Cable Lay: CLV

Turbine: WTIV

Crew: CTV/CSOV

Towing: AHTS/Tugs

Marine Operations Plan

Marine Warranty Survey (MWS) Requirements

•Classification of all operations: “warrantable”

•Documents submitted to MWS:

•Load-out procedures

•Transport and sea fastening plans

•Lift and installation method statements

•Vessel certification and weather downtime analysis

Local Compliance & Permits

Contingency & Recovery Plan

•Adverse weather downtime handling

•Equipment or vessel failure scenarios

•Alternate port options

•Standby crew and vessel strategy

Lessons learn from Taiwan

•The Yunlin Offshore Wind “pile slip” incidents refer to three separate accidents during foundation installation in Taiwan’s Yunlin offshore wind farm project, where monopile foundations slipped unexpectedly during piling operations.

•Key Points

•Three incidents

•First (2021) – Occurred during early construction by Sapura Energy’s Sapura 3500.

•Second (2022) – Happened with NPCC’s DLS 4200 before completing foundation installation.

•Third (June 4, 2023) – Confirmed by the developer; immediate investigation launched.

•Causes – Likely due to excessive piling speed, poor seabed conditions, and lack of sufficient offshore installation experience.

Impact –

•Severe project delays and sharply increased costs (nearly doubled).

•Required multiple financial restructurings to keep the project going.

•Triggered government investigations and calls for greater transparency.

造船工程與海洋工程是傳統又現代的產業,在台灣已發展超過100年。台灣是個海洋國家,也是個海運大國,近年來又發展離岸風力發電產業,船舶便成重中之重!希望這些文章可以引起大家的關注與重視。

運轉維護(O&M) •完成併聯後風場開始營運,風場運轉維護則涉風機運維、海底基礎運維以及電纜運維等三大項目。離岸風場運維須將人員送至風機點位,國外稱ACCESSIBILITY(送達),因天候因素若能提高抵達率至70%為佳,台灣風場若能達60%為佳。 •人員送達倚靠CTV(crew transfer
