Evaluating technical and financial factors for commercialising floating offshore wind: A stakeholder analysis

Recently, floating wind has enjoyed much public and governmental attention and is commonly identified as a crucial next step on the route to net zero targets for many countries. However, there is currently a large gap between the scale and readiness-level of devices in the water and the end-of- the-decade aspirational targets of many governments...

Capacity and Intra-Hour Ramp Reserves for Wind Integration

We propose a power-based unit commitment formulation with capacity and intra-hour ramp reserves for dealing with intra-hour wind power variability and uncertainty. Although the formulation has an hourly resolution, the intra-hour ramp requirements capture wind power ramp excursions with a time duration below one hour, and thus allows the...

Future material requirements for global sustainable offshore wind energy development

Offshore wind energy (OWE) is a cornerstone of future clean energy development. Yet, research into global OWE material demand has generally been limited to few materials and/or low technological resolution. In this study, we assess the primary raw material demand and secondary material supply of global OWE. It includes a wide assortment of...

Pile driving acoustics made simple: Damped cylindrical spreading model

Sound produced by marine pile driving activities poses a possible risk to marine life. The assessment and mitigation of this risk requires a precise prediction of the expected levels. An analytical approach to estimate the radiated sound exposure levels is presented, based on the axial symmetry of the problem, resulting in damped cylindrical...

Underwater noise measurements in the North Sea in and near the Princess Amalia Wind Farm in operation

Optimal support vessel and access system selection for offshore wind farms

Operation and maintenance (O&M) costs contribute to a significant part of Cost of Energy produced by offshore wind. In order to reduce the O&M costs and to guarantee safety and wellbeing of the maintenance technicians, for each individual wind farm an optimal set of support vessels and access systems should be selected. This selection should...

Underwater sound and vibrations due to oil & gas activities

In the oil & gas industry there is a trend towards more subsea activities. To improve gas recovery from existing and new fields at greater depths, the produced gas will be compressed, processed and transported via subsea templates and underwater networks (pipelines, flexible risers, etc.). Besides the huge consequences for the subsea...

Intelligent energy management using powermatcher: Recent results from field deployments and simulation studies

Response of demand, distributed generation and electricity storage (e.g. vehicle to grid) will be crucial for power systems management in the future smart electricity grid. In this paper, we describe recent results using PowerMatcher a smart grid technology that integrates demand and supply flexibility in the operation of the electricity system...

Experience of wind turbine manufacturers with wind turbine certification: report of subtask A1 of project EWTC

This report describes the findings of subtask A1 of the project EuropeanWind Turbine Certification (EWTC). The main objective of the EWTC project is to realize a uniform harmonised wind turbine certification in the European Union, in order to remove trade barriers, speed up implementation and further reduce wind energy costs. The harmonised...

Description of the North Sea wind climate for wind energy applications

In The Netherlands it is foreseen that wind turbines will be installed on offshore locations in the North Sea before the year 2010. Therefore adequate knowledge of the offshore wind climate should be obtained, both for the estimation of energy yields and for the determination of wind load parameters. For this purpose databases of two offshore...
