Movement Responses of Seals During Pile Driving for Offshore Wind Farm Construction

open access: yesAnimal Conservation, EarlyView.
Despite rapid growth of the renewable energy industry to meet climate change targets, predictions of population‐level impacts on wildlife are currently hindered by a limited understanding of individual behavioural responses to these developments.

High Strength Steel Fatigue Crack Growth Database for Offshore Renewable Energy Applications

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT High strength steels can reduce costs and carbon emissions in offshore renewable energy, but their effect on structural integrity remains unclear. In welded structures, such as support structures for offshore wind and tidal turbines, fatigue life is dominated by crack growth from flaws at weld toes.

Uncertainty Quantification and Attribution for Resilient Infrastructure Systems

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Infrastructure resilience is critical for maintaining the delivery of essential services to society. However, although computational modelling is integral to infrastructure management, infrastructure model outputs are conditional on a range of uncertain assumptions, both in the present day and under future climate change.

Impact of structural flexibility on loads on tidal current turbines [PDF]

open access: yesInternational Journal of Marine Energy, 2016
In the development of tidal current turbines there are two common approaches regarding the required level of detail for load simulations. Those two are either to simulate the pressure field in detail with computational fluid dynamics (CFD) and assume a rigid geometry or to use a high fidelity structural model and simulate the hydrodynamic blade loads ...

Digital Twins for Offshore Wind Operation and Maintenance: A Review

open access: yesWind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT Offshore wind has become a key focus for achieving carbon neutrality. However, offshore wind turbines face considerable operational and maintenance challenges due to harsh conditions and difficult access. Integrating digital twin technology helps support operation and maintenance activities.

A review of survivability and remedial actions of tidal current turbines [PDF]

open access: yesRenewable and Sustainable Energy Reviews, 2015
Abstract Tidal current energy is one of the most predictable ocean renewable energies. Survivability of the device used to harness tidal power and its remedial actions are critical to ensure a successful power generation. Marine environment is harsh with the continuous attacks of waves, current, saline water and microorganism.

Estimating the total mortality of seabirds following a marine heat wave

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.
