Surrogate based sensitivity analysis and uncertainty quantification of floating wind turbine mooring systems

Offshore wind business feasbilility in a flexible and electrified Dutch energy market by 2030

Offshore wind is the primary supplier of CO2-free electricity moving towards decarbonising the Dutch power system. The installed capacity aims to increase sevenfold to 21.5 GW by 2030. However, the current market trends of increasing renewable capacity, industrial electrification, gas and CO2 prices, the expansion of interconnection, and the...

The potential of shared offshore logistics. North Sea Energy 2020-2022

Offshore logistics play a key role in ensuring the safe and efficient installation, operation and decommissioning of offshore energy systems. This sector is currently facing substantial changes due to the planned decline in offshore gas production and the rapid growth of offshore wind, as seen in Figure 1. Currently, significant attention is...

Modelling offshore wind-battery hybrid systems to evaluate flexibility in the Dutch power markets

Levelized cost of energy and life cycle assessment of IDL (Integrated Lightweight Tower) Tower

The offshore wind industry is growing rapidly, both in terms of market capitalisation and in terms of component (turbine and support structure) sizes. A pricing breakthrough can be expected because of two industry trends: increasing turbine capacity up to 15 MW and an increased operational lifetime of 25-30 years. For both trends a smart,...

Pathways to potential cost reductions for Offshore wind energy

To investigate the potential cost reductions for offshore wind energy a study has been conducted by TNO and BLIX Consultancy. The research has been commissioned to TNO and BLIX Consultancy by RVO1 and TKI Wind op Zee. The study has been divided into three phases, phase I aimed at potential cost reduction to be achieved by scaling up present...

Developing a long lasting offshore wind business case in the Energy Transition by 2050

The European offshore wind energy ambition is to become a key source by 2030 and to meet more than 50% of power demand by 2050. This requires to increase the capacity from current 22 GW to 450 GW in the North Sea. However, the very high share of electricity production from offshore wind is increasing the stochastic nature of the power system and...

Combined wind turbine design and wind farm layout optimisation under wind resource uncertainty

Applications of the wind farm layout optimisation problem focus on optimally positioning a certain number of turbines within a wind farm so that annual energy production (AEP) is maximised. This study addresses an earlier stage in the wind farm development process. Instead of optimising the individual positions of a certain number of turbines of...

Combined wind turbine design and wind farm layout optimisation under wind resource uncertainty

Automated daily maintenance planning for offshore wind farms

Offshore wind farm managers and schedulers need to manage large numbers of wind turbine visits every day, in order to: repair minor faults; conduct inspections; and perform scheduled service operations. Daily schedules form a choice of which maintenance activities to conduct, taking account of: constraints on weather conditions, shifts, vessel...

Innovations for Port of Den Helder Infrastructure following Offshore wind developments

A study to investigate opportunities for the Port of Den Helder in the energy transition is performed by ECN part of TNO, with the support of a consortium of nine partners, all stake holders in the Port of Den Helder. Although it is foreseen that activities related to the oil and gas (O&G) industry will decrease in the coming years, a...

Including Realistic Vessel and Human Behaviour in Simulations of Offshore Wind Farm Operations

During the Offshore Maintenance Joint Industry Project (OM JIP), the offshore wind farm simulation tool ECN O&M Access has been upgraded from version 1.0 to 2.0, enhancing the modelling of wind farm accessibility by incorporating vessel hydrodynamics and motion-induced human fatigue. Case studies are performed using the new version of ECN O&M...
