Thirteen companies from the
wind, oil & gas and maritime sector have launched the Joint
Industry Project “Coupled Analysis of Floating Wind Turbines“
led by DNV GL to develop a new Recommended Practice.
DNV GL, the world’s largest resource of independent energy
experts and certification body, has launched a new joint
industry project (JIP) together with thirteen global partners to
mutually develop a Recommended Practice for the coupled analysis
of floating offshore wind turbines. Despite the fact that the
wind industry has a strong focus on the development of floating
offshore wind turbines, it is still missing a widely recognised
and unified approach for the practical methods to build and
validate the numerical models, in accordance with the
requirements in the standards. Standardisation is a key
milestone to guide the industry towards the development of
reliable floating wind turbines. Guidance includes setting up
minimum requirements for the design on new concepts that can
help investors’ evaluation, and supporting the more mature
technologies towards a safe and secure commercialisation.
The project is the first of its kind, bringing together multiple
stakeholders from the wind, oil & gas and maritime industries,
making it the most interdisciplinary project that engages in the
technical advancement for floating offshore wind projects to
date.
The participants come from a broad range of industries,
including utilities, component manufacturing, engineering
consultants, maritime research institutes, shipyards and
academic research. The following companies are contributing to
the development of the new Recommended Practice:

Floating wind turbine specialist Denis Matha from Ramboll
commented on the engineering consultancy’s participation in this
project: “Ramboll supports this joint industry project and will
contribute to this effort by providing our knowledge and
experience in the design and analysis of floating wind turbines,
covering coupled simulation as well as our structural, mooring
and cable expertise. We expect that this project will provide an
excellent platform to jointly develop a Recommended Practice by
addressing the key issues and bringing together the expertise of
key stakeholders.”
Ideol’s CEO Paul de la Guérivière said: “We are happy to join
this JIP and share our years of experience coupling multiple
wind turbines with our patented floater. We have been convinced
for a long time of the benefits of a common framework for the
loads analysis of floating wind turbines and are confident that
such efforts will lead to substantial gains in efficiency and
cost. The Recommended Practice should strongly help the floating
offshore wind industry and accelerate the development of
commercial-scale floating wind farms.”
The new Recommended Practice will build on the experience from
the application of the Offshore Standard DNV-OS-J103 “Design of
Floating Wind Turbine Structures“ which was published in 2013
and will contain methods and ways to fulfil the requirements set
in DNV-OS-J103.
Since its publication, the offshore standard DNV-OS-J103 has
been broadly used for the design of floating wind turbine
structures. At the time of publication, the practical
experiences in the field of floating offshore wind energy have
been rather limited in providing reliable information on
validating numerical models for the turbine construction and
reliable insight on the level of complexity required at each
individual project stage. Over the last three years, the
industry has greatly advanced moving the commercialisation of
the new technology forward, as the world’s first floating wind
farm demonstration projects have since been launched.
Based on the latest knowledge and practical know-how, the joint
approach of developing the future Recommended Practice will
greatly reduce the risk of inadequate analysis, leading to
substantial time savings. Further advantages stem from the focus
on the design of floating wind turbines and the validation of
numerical models in respect to their subsequent certification.
The coherent structure of the Recommended Practice also provides
a unified cost structure for the project development process.
Luca Vita, Project Manager of the Joint Industry Project and
Senior Engineer at DNV GL – Energy, Renewables Certification
commented: “The analysis of floating wind turbines is a complex
challenge that requires the integration of different
technologies and disciplines. The lack of a common agreement on
the optimal approach to conduct these analyses during the
different stages of the design process adds potential risk
factors and time delays in the project development, but also in
the cost evaluation of new conceptual designs. This project
provides a unique platform to mutually develop an invaluable
Recommended Practice which will be beneficial to each industry
stakeholder, taking the wide-ranging spectrum of
interdisciplinary skills and business objectives of each
participant into account.”
Johan Sandberg, Segment Leader - Floating Wind Turbines at DNV
GL – Energy added: “We are very happy to continue our commitment
to making floating wind power a reality and a large scale energy
technology. Understanding coupled analysis is a key part of
designing and optimising a floating wind turbine and it is
encouraging that the industry’s interest in this has been so
strong. The partners in this project contribute with a wide
range of valuable competences, which will make the result
effective and credible.”
