14:30 - 16:00 Turbine technology - Fixed to the seabed
This session is focused on the substructures for off shore wind turbines. Focus will be on how foundations will look for continuously larger turbines at increase water depth - some of their design drivers, and impact on cost reduction.
Presentations will reflect all relevant foundation types, ranging from steel to concrete, from fixed-bottom to floating - new development implemented and research conducted - what are the findings?
- How solid experience contributes to improving the future design basis
- The potential cost optimization for the future foundation solution
- Learn about newest developments, such as jacket structures with bucket foundations
- How to evaluate remaining lifetime of your assets

Hywind floating wind - a game changing technology
Hywind Demo, the world's first full scale prototype was installed in NOrway in 2009, after nearly a decade of design development and testing. Building on Statoils more than 40 years of experience within offshore design, managing large and complex projects and safe operations.
The presentation will give evidence that floating wind is feasible, and that it has potential to be a cost efficient solution for offshore wind, and also to point to the specific efforts Statoil is considering to make this happen.
Main body of abstract
The results from the Hywind Demo projects have exceeded expectations. With its simplicity in design, Statoil also belives it can be a competitive and groundbreaking technology for the offshore wind industry. It is suitable for mass production, and has advantages over fixed solutions in its efficiency in assembly and installation. Floating wind is also more flexble in siting, meaning one can reach areas with stronger winds, and deeper. Statoil is now planning to deploy ist first floating windfarm, off the coast of Scotland. The Hywind Scotland projects will utilise 6 MW turbines, requiring a scale up in design. Building on the experience from Hywind Demo, we regard this to be feasible, and a promising solution for future utility scale deployment. The main objectives for Hywind Scotland will be to demonstrate cost efficiency and reduce risk for future utility scale deployment. STatoil believes that floating wind will be competitive with fixed in a mature market.
Floating wind will be competitive with fixed in a mature market. Hywind is an efficient design suitable for rough conditions, and also for efficient fabrication and installation. Hywind will be ready for commercial deployment from 2020 onwards.
Share experience from 5 full years of testing of the Hywind concept
Approach to scale up of the design to state of the art turbine design
Objectives for the first floating wind farm, such as interaction between turbines, improved fabrication, assembly and installation, preparing for utility scale deployment
