Offshore Wind Accelerator

Offshore Wind Accelerator is a Joint Industry Programme to drive down costs

› Joint industry project involving 9 developers + Carbon Trust

› The largest and most established innovation programme

› New lower-cost technologies, ready to use

› Simple governance model

› Over £100m total programme spend to date

› Industry has funded >60%

› An industry-led initiative

› Value to government and industry partners

› Great leverage for industry partners (>13x)

› Efficient vehicle for government to accelerate innovation and attract international interest

› Set up 2008 in response to the need to bring down the cost of Offshore Wind

Involved in over ¾ of all operating EU wind farms

Offshore Wind Accelerator

Five research areas

Focus on technology de-risking and cost reduction

Each research area has a Technical Working Group (TWG) with technical experts from developers

Developers are supervising, tracking the progress of ongoing projects and reviewing results.

Carbon Trust is managing the TWG’s and hosting the TWG meetings.

OWA Impact

Recommended boat design

■ Provide the industry with a better understanding of the interaction and impact of crew transfer vessels (CTV) on boat landings during push-on transfers

■ Reduce unnecessary differences in geometry between boat landings, enabling CTV’s to operate efficiently between different sites

■ Produce a recommended boat landing geometry taking into account the better defined CTV loads as well as industry feedback and recommendations.

■ Engage with industry to consider their know-how and feedback, and to disseminate the work results and ensure buy-in.

Reducing emissions and fuel consumption in offshore wind vessels

Project Objectives:

■ To reduce vessel emissions, fuel costs and vessels’ operational maintenance costs for offshore wind operations

■ Understand and evaluate the cost-benefit of existing and future powering and storage technologies, particularly from other industries

■ Run an industry challenge or competition to de-risk and accelerate the introduction of technology to reduce vessel emissions for offshore wind through

■ Determine the infrastructure required for integrating this new technology into offshore wind operations

■ Go beyond regulatory requirements for the maritime industry to make offshore wind pathfinder for LEV technology 6

P-Plot App

Minimize barriers to generating P-plots, allowing for benchmarking of a wider number of CTV’s, aiding selection of appropriate vessel according to windfarm needs

■ Uses smartphone device as a ‘micro VMMS’

■ Produce p-plots for both transit and transfer operations

■ Wave buoy mode – uses micro VMMS tool to generate current metocean profile

■ Currently in beta testing, but should be released in November (beta sea-trails underway at the moment)

Drones for offshore wind O&M

Project objectives:

■ Understand and evaluate the potential of drones to reduce the cost of O&M activities and improve turbine availability

■ Understand and evaluate the potential HSSE benefits of using drones to support the O&M of offshore wind farms

■ Understand and evaluate the drone as a platform as well as the capabilities of sensors that can be fitted onto drones

■ Understand and evaluate the relevant regulatory landscape regarding the use of drones/unmanned vehicles in offshore wind O&M activities, across different markets (particularly in Europe)

■ Evaluate if drones require further support to provide the required tools specifically for offshore wind O&M activities

Source: Risktec

- The main objectives of this project were to:

- Assess the risks of sliding access in offshore wind and mitigation methods.

- Assess the skills and competence requirements for undertaking sliding access.

- Create a method for comparing vessel performance for sliding access.

- Review the systems available in the market or under development that could support the de-risk sliding access.

Scope of Work – Project in delivery

Monitoring & Inspection

No dynamic cables available above 66kV

The key challenges of going to ~220kV:• Fatigue under dynamic loading• Installation and handling of stiffer cables• Manufacturing capability for contra-wound

armour wire• Required accessories such as buoyancy

modules• Transition point from static to dynamic cable• Limitations of current standards

Challenges identified

Dynamic Export Cable

• Evaluation of technical challenges

• Identify standards

• Define testing requirements

• Competition to support cable suppliers

• Working with cable suppliers to develop DECs

Evaluation of Offshore Maintenance versus Tow to Port Maintenance strategies

Offshore maintenance at site utilising heavy lift offshore maintenance• Floating units remain connected, with component exchange

undertaken by a floating crane vessel or alternative method.

Tow-to port• Floating turbines disconnected from mooring lines and cables and

towed to a port for maintenance using an onshore crane or crane vessel

Project Overview

Principle Power

Offshore versus Tow to Port Maintenance

• Evaluate state-of-the-art methods & innovative solutions for the different maintenance strategies

• Undertake feasibility studies & produce detailed method statements for each maintenance strategy;

• Undertake logistics assessments for large wind farm maintenance campaigns, with component exchange on multiple turbines;

• Produce cost estimates for each strategy, including sensitivity studies;

• Evaluate technology development needs to optimise the maintenance operations & engage with the market to identify innovative solutions;
