Presenter's biography

Biographies are supplied directly by presenters at EWEA 2015 and are published here unedited

Dr Laure Grignon is a Technical Analyst within the RES Offshore engineering department and a Chartered Marine Scientist. Her main expertise is in the provision of Metocean criteria for the design, installation and operation of offshore and maritime assets. She joined RES Offshore in 2012 and has since managed the Metocean package for the St-Brieuc Offshore Wind Farm, and advised the offshore team on many other projects. She also develops technical tools and leads technical studies in order to optimise specific elements of projects, such as array cable layouts and installation strategies, on a wide range of projects.

New Guidelines for managing the Metocean component of Offshore Wind Projects


Metocean is a technical engineering discipline that addresses meteorological and physical oceanographic conditions. In the context of an Offshore Renewables project, it is the characterisation of the hydrodynamic environment for which the project is designed, and in which it is constructed, operated and decommissioned.

The Institute of Marine Engineering, Science and Technology (IMarEST)’s Offshore Renewables Special Interest Group (ORSIG), with support from the Operational Oceanography Special Interest Group (OOSIG), has produced a Metocean Procedure Guide (MPG) tailored to the Offshore Renewables industry).


The MPG outlines the metocean activities required to support all phases of an offshore renewable energy project. It concentrates on the key information that project managers and specialists need to consider in order to better understand the impact of the metocean conditions on the project and to develop a strategy for managing that risk.

Main body of abstract

The MPG describes the requirements for the characterisation of metocean data during the whole project lifecycle, from the site selection and feasibility through to decommissioning. It then reviews what data must be obtained, how to obtain it, and how to manage it, in order to meet industry standards used as the basis for certification.

A metocean strategy is recommended for offshore renewables projects. Three main deliverables are expected from the metocean package during the development and engineering phase, in which metocean activities are the most intensive:
- A metocean briefing note gives an overview of the metocean conditions and identifies those that may prevent the technical feasibility and economic viability of a potential project. This is used at an early stage of the project.
- Preliminary engineering data and analyses typically meet the requirements for conceptual definition of the project and consent application. The milestone defined by the project, and the level of engineering on which the data and analysis are to be based for a given milestone, will dictate how accurate and comprehensive the data should be.
- Full engineering data and analyses will comprise a high quality, accurate account of metocean conditions, typically based on detailed modelling validated against in-situ measurements, and taking account of spatial variability. It will be required as soon as is practicably possible within the design phase and will form the basis of engineering design and decisions throughout the engineering phase.


The MPG makes key recommendations:
- The metocean conditions should be considered at the feasibility/selection stage of the project, because they have a significant impact on its risks and costs, at all stages.
- A Metocean Technical Authority should be established within Offshore Wind Project teams in order to ensure that the metocean inputs are consistently managed, and integrated to the development process.

Learning objectives
The MPG compiles insights collated by engineers and metocean specialists experienced in the offshore renewable sectors. It aims to share this knowledge more widely.
