A two-dimensional model based on Open Tidal Farm is
applied to simulate tidal stream flow around turbines. The
model is governed by shallow water equations and can
optimize the layout of the deployed turbine array to
maximize the energy outputs. Three turbine array layouts,
including two structured designs (regular and staggered)
and one unstructured layout (optimized), are simulated to
investigate the effect of turbine layouts on energy
extraction. The present study shows that more energy
could be extracted when lateral spacing decreases and
longitudinal spacing increases within the same domain,
namely the effective turbine layout is to deploy more
turbines in the first row to extract energy from an
undisturbed tidal stream, while larger longitudinal spacing
will make it possible for a tidal stream to recover more
before reaching the next turbines row. Taking the tidal
stream turbines array around Zhoushan Islands as a case
study, results show that the optimized layout can extract
106.8% energy of that extracted by the regular and
staggered design for a full tide in the same marine area.
Additionally, the turbine array greatly influences tidal
stream velocities immediately behind the array and has
little effect on far-field wake flow.
This paper briefly reviews the available and proposed
solutions for the tidal current turbines. The idea is to
overview the different types of technologies involved in
the tidal current energy conversion systems rather than
summarize the different market solutions. The paper
concludes by highlighting the major challenges faced by
the tidal current turbine industry and an indication of the
current trends in the industry.

Offshore energy sources, such as offshore wind turbines,
are promising alternatives. However, the abnormal climate
is a potential threat to the safety of offshore structures
because construction guidelines cannot embrace climate
outliers. A cosine similarity-based maintenance strategy
may be a possible solution for managing and mitigating
these risks. However, a study reporting its application to
an actual field structure has not yet been reported. Thus,
as an initialstudy, this study investigated whether the
technique is applicable or whether it has limitations in the
real field using an actual example, the Gageocho Ocean
Research Station.

The authors of this document have constructed a global
remote sensing-based offshore wind turbine (OWT)
database derived from Sentinel-1 synthetic aperture radar
(SAR) time-series images from 2015 to 2019. They have
developed a percentile-based yearly SAR image collection
reduction and auto-adaptive threshold algorithm in the
Google Earth Engine platform to identify the
spatiotemporal distribution of global OWTs. By 2019,
6,924 wind turbines were constructed in 14 coastal
nations. An algorithm performance analysis and validation
were performed, and the extraction accuracies exceeded
99% using an independent validation dataset. This dataset
could further the understanding of the environmental
impact of OWTs and support effective marine spatial
planning for sustainable development.

Wind energy resources are subject to changes in climate,
so the use of wind energy density projections in the near
future is essential to determine the viability and profitability
of wind farms at particular locations. Thus, a step forward
in determining the economic assessment of floating
offshore wind farms was taken by considering current
and near-future wind energy resources in assessing the
main parameters that determine the economic viability
(net present value, internal rate of return, and cost of
energy) of wind farms. This study was carried out along
the Atlantic coast from Brest to Cape St. Vincent.

This review provides a critical, multi-faceted assessment of
the practical contribution of tidal stream energy to the UK
and British Channel Islands' future energy mix. Evidence is
presented that broadly supports the latest national-scale
practical resource estimate of 34 TWh/year, equivalent to
11% of the UK's current annual electricity demand. The
size of the practical resource depends in part on the
economic competitiveness of projects.

The demand for a modern wind energy conversion
system (WECS) has increased to achieve a suitable
alternate renewable energy source. In this paper, after a
brief introduction, the classification of WECS is reviewed
with attractive illustrations. The various mechanical

power grid integration.
Wave energy is one of the renewable resources with high
availability area of the wave across the world. However,
the wave power density in Malaysia is smaller compared
to other countries with progressive development in Wave

benefit of outdoor activities. Thus, this paper presents the
modeling of a tubular longitudinal permanent magnet
linear generator for wave energy conversion for outdoor
activities.

Parametric resonance has been observed, both
numerically and experimentally, in various wave energy
converters (WECs) studies.
This study analyzes energy transfer between heave and
pitch/roll modes when parametric resonance occurs. A
generic cylindrical point absorber is studied as a WEC
floater to consider non-linear wave-structure interaction,
including non-linear Froude-Krylov and viscous forces. A
heave-pitch-roll three-degree-of-freedom model is derived
for the numerical study of the energy transfer between
different operational modes.

Wave energy conversion technologies have recently
attracted more attention due to global efforts to replace
fossil fuels with renewable energy resources. While ocean
waves can provide renewable energy, they can also be
destructive to coastal areas that are often densely
populated and vulnerable to coastal erosion. There have
been a variety of efforts to mitigate the impacts of wave-
and storm-induced erosion; however, they are either
temporary solutions or approaches that cannot adapt to a
changing climate. This study explores a green and
sustainable approach to mitigating coastal erosion from
hurricanes through wave energy conversion.

A complete surveillance strategy for wind turbines
requires both condition monitoring (CM) of their
mechanical components and the structural health
monitoring (SHM) of their load-bearing structural
elements (foundations, tower, and blades). Therefore, it
spans both the civil and mechanical engineering fields.
Several traditional and advanced non-destructive
techniques (NDTs) have been proposed for both areas of
application throughout the last years. This document
extensively reviews these non-destructive approaches;
more than 300 scientific articles, technical reports, and
other documents are included in this review,
encompassing all the main aspects of these survey
strategies.
The documents are classified chronologically from 2020 to 2023.

The ultra-high pressure water jet is a kind of high-energy
water jet, which is pressurized by a high pressure pump to
make the pressure reach hundreds or even thousands of
megapascals, and ejects a high-energy water stream from
the nozzle with special aperture at a very high speed of
100-1000m / s.
The water stream has a very strong hitting power, and

High-pressure water jets are often used as a tool for
cleaning, cutting or for modification of the surface
morphology.
The nozzle design has a considerable influence on
cavitation and wear effects as well as on the nature of the
exiting jets.
Different applications are affected by different flow
regimes, such as cavitation or hydraulic-flip, which
depend on the radius of the nozzle edge.

Underwater explosion cavitation has an important
influence on the shock wave, explosion bubble, and
structural deformation. The one-fluid model is usually used
in underwater explosion cavitation. It is assumed that the
cavitation is induced suddenly when the pressure is lower
than the saturated pressure. The biggest deficiency of the
model is that it is difficult to consider the temperature
change in the cavitation domain.

Underwater explosion cavitation is generally simulated
using a one-fluid model based on compressible
multicomponent flows. Owing to the lack of mass and
heat transfer between liquid and vapor phases, this model
is incapable of extensively analyzing the cavitation
mechanism in an underwater explosion. In this study, the
authors extend the phase transition model provided by
Chiapolino et al. to the field of underwater explosion
cavitation. The model presents a more accurate
description of the thermodynamics of cavitation processes
involving liquid–vapor phase transition.

the studies on the underwater blast-resistant performance
of wharves, e.g., reinforced concrete (RC) caissons, has
become an urgent demand. At present, the influence of
water level on caisson subjected to underwater explosions
was studied experimentally and numerically, e.g.,
underwater explosion loading characteristics and dynamic
behaviors of caisson. Firstly, four shots of underwater
explosion test were carried out both in free field and on a
partially submerged caisson specimen, and the
overpressure and deflection-time histories, as well as the

Piled floating pontoons are public access structures that
provide a link between land and sea. Despite floating
pontoons being frequented by the public, there is limited
data available to coastal or maritime engineers detailing
the dynamic motions (acceleration and rotation) of these

motions on public comfort and safety to inform their
design. This contribution summarizes results from a set of
laboratory-scale physical model experiments of two
varying beam width piled floating pontoons subjected to
boat wake conditions.
