TRANSITIONING FROM near shore TO far from shore PROJECTS


Utility’s Perspective: Vessel Providers In The Web Of Operational Expectations And Responsibilities

  • How to meet utilities' standards

  • Creating enough flexibility to deal with complications, delay claims etc
  • What are the constraints currently in place?  
  • Can SOVs be an option for R2 projects? Can you justify SOVs and daughter craft costs compared to CTVs?

Kristof Verlinden, O&M Manager, Parkwind 


Access Systems: State Of The Market And Beyond

  • Overview of existing and under-development access systems
  • What cost reductions can be realized through access systems in O&M until 2020?
  • Optimal O&M strategy and access system selection already from the design phase

Piet  Warnaar,  Senior Business Developer, ECN Wind 


Networking Break And Morning Refreshments 


PANEL DISCUSSION: Transition From Near To Far From Shore Projects: Adapting Existing Technology Or Investing In New Designs? How Can You Maximise Your Available Assets?

  • Increasing vessel efficiency and reduce downtimes whilst containing costs
  • Real examples on R2 available assets being used for R3 projects
  • Creating the perfect mix of SOVs, Heli, Jack-ups and CTVs for your projects
  • From CTVs to SOVs – what about a solution in between?
  • Main component exchange, general maintenance and sub-sea repair
  • What is the impact of R3 projects on R2 wind farms in terms of vessel availability, prioritisation, O&M costs and delays


Kristof Verlinden, O&M Manager, Parkwind

Keld Kristensen, Marine Project Manager, MHI Vestas  

Moderator: Captain Mike Vanstone,  Marine Operations And Technical Manager, Maritime Operations Department,  Vattenfall


Networking Lunch 

Further Offshore: The Changing Role Of CTVs, SOVs, Jack Ups and Helicopters 


The Crown Estate’s Update On  The Offshore Renewables Aviation Guidance (ORAG) Document

  • Use the ORAG to open up the potential use of helicopters to service further offshore wind farms
  • Providing a framework for the industry to develop consistent and coherent aviation support strategies for deployment in the offshore energy industry
  • Encouraging the industry to use it in making more informed decisions on their wind farm with regard to vessel and access operators
  • Engagement with aviation stakeholders to address any broader policy, regulatory, safety and technical matters

Matthew Clear,  Senior Development Manager – Strategic Workstream,  The Crown Estate

Peter Lloyd,  Head Of Centre Of Competence EHS Offshore,  Siemens


Helicopters: Determining Access Benefits, Weather Limitations And Impact On Vessel Design

  • How are OEM contracts shaping up when taking helicopters into account?
  • Overcoming limitations such as:

- Many weather restrictions 
- Visibility 
- Flying in the dark 
- Pilot skills 

  • How are vessels going to accommodate helicopters when this far out?
  • Oil & Gas experience on the use of helicopters far offshore- safety performance vs. marine options 
  • Weather constraints - aviation vs. marine 
  • Accommodation platform with helideck

Exploring The Potential And Limitations Of CTVs For Further Offshore Wind Farms  

  • What is the strategy with CTVs? Will they be completely out of the picture or is there an opportunity to employ them?
  • Learn from different stories on how operators want to utilise CTVs in the field in order to efficiently maintain their wind farms
  • Can CTVs operate from the SOVs and use them as ports?
  • How to reduce the number of CTVs and fuel hours to reduce environmental impact and cost 
  • From 12-pax limit to 24-pax – how does higher capacity impact CTV weight and, consequently, access? 

Cost-Effective Surface Effect Ship (SES) Solutions For Near And Far From Shore Wind Farms

  • Why a small SES offers same performances as a larger vessel
  • Reduced operating costs: Fuel savings with Surface Effect Ships
  • The ESNA Sea Puffin SES Daughter Craft
    • A Daughter Craft with the performance of a CTV
    • Launch And Recovery with commercially available single-hook davit systems

Nere Skomedal, Naval Architect and Co-Founder, ESNA

Trygve Halvorsen Espeland, Naval Architect and Co-Founder, ESNA 


Networking Break And Afternoon Refreshments 


The Evolution Of SOVs/W2W Vessels In Adapting From Near To Far From Shore Wind Project Requirements  

  • An overview of how SOVs/W2W have been meeting different type of needs from R1 to R3 projects
  • How have they changed in terms of size and performance?
  • IMO Classification of “industrial personnel” – how will this influence SOV size?
  • Meeting client needs in terms of :
    • Capacity
    • Transfer of technicians:  
      • Gangway systems being used
      • Safe transferable system and capacity
      • Cooperating with CTVs
Tim Boerner, Offshore Shipbroker, Global Renewables Shipbrokers 

Unlocking Efficiencies And Optimisation Of Jack-up (WTIV) Operations Through Analysis

  • Overview of jackup operations for renewables
  • Requirements for warranty
  • Finding the right balance between desk-study and operations to gain time/cost savings on site:

a) Reduced analysis costs by undertaking generic and conservative assessments that cover many jacking locations in a single field

b) Reduced operational costs by undertaking bespoke assessments on a per-location basis to optimise parameters and reduce operational time

  • As existing WTIV’s move further offshore and reach their limits, the benefits of b) become more apparent

Ankor Raithatha, Team Lead, Jack-up, Geotech And Metocean, DNV GL 


Floating Wind: What Can Vessel Providers Do To Counteract Installation And O&M Challenges For Supporting Floating Advancements?

  • Floating Platforms: new built concept vs. fixed structures and logistic hubs
  • What can we do? Can we do more work with floating?
  • Can we do more work with floating wind? 
  • High sea state floating; what’s going on in that space?
  • Floating turbines: how are we going to maintain them?
  • Deeper water projects - how are you going to change gearboxes? 
  • The impact on technician transfer 

End Of The Day Utilities And Developers Panel Discussion:

  • Wind farm operators: what do they have in mind for R3 vessels? How can vessel designers meet those needs whilst containing costs?  
  • How are utilities using current technologies? Where and how such use can be maximised?
  • How to deal with growing 1GW wind farm at a strategic and daily level
  • How to plan ahead with your SOVs, wind turbine service and models being used
  • Rethinking the way you use available technology
