The Optimal Configuration of Wave Energy Conversions
Ocean energy is one potential renewable energy alternative to fossil fuels that has a more significant power generation due to its better predictability and availability. In order to harness this source, wave energy converters (WECs) have been devised and used over the past several years to generate as much energy and power as is feasible. While it is possible to install these devices in both nearshore and offshore areas, nearshore sites are more appropriate places since more severe weather occurs offshore. Determining the optimal location might be challenging when dealing with sites along the coast since they often have varying capacities for energy production. Constructing wave farms requires determining the appropriate location for WECs, which may lead us to its correct and optimum design. The WEC size, shape, and layout are factors that must be considered for installing these devices.

Traditional Seaweed Farming Methods
The imperative to substantially expand the world’s seaweed aquaculture supply is well established in published literature and has the strong backing of virtually all global non-government organizations (NGOs). The expansion of seaweed farming is recognised as one of the best approaches to realising many of the sustainable development goals of the United Nations.

USRC Washington (1832)
The United States Revenue Cutter Washington was one of the 13 cutters of the Morris-Taney class. These cutters were the backbone of the United States Revenue Cutter Service for more than a decade. Samuel Humphreys designed these cutters for roles as diverse as fighting pirates, privateers, combating smugglers and operating with naval forces. He designed the vessels on a naval schooner concept. They had Baltimore Clipper lines. The vessels built by Webb and Allen, designed by Isaac Webb, resembled Humphreys' but had one less port.

Salinity and Turbidity in the Red Sea
Several industrial and scientific underwater applications require high-speed wireless connectivity. Acoustic communications have low data rates and high latency, whereas attenuation in seawater severely limits radio frequency communications. Optical wireless communication is a promising solution, with high transmission rates (up to Gb/s) and little attenuation in water at visible wavelengths.

Underwater Image Enhancement and Underwater Biological Detection
For aquaculture resource evaluation and ecological environment monitoring, the automatic detection and identification of marine organisms is critical; however, due to the low quality of underwater images and the characteristics of underwater biological detection, the lack of abundant features can impede traditional hand-designed feature extraction approaches or CNN-based object detection algorithms, particularly in complex underwater environments.

Fixed and Floating Offshore Structures
Diverse forms of offshore oil and gas structures are utilized for a wide range of purposes and in varying water depths. They are designed for unique environments and water depths around the world. The applications of these offshore structures require different activities for proper equipment selection, design of platform types, and drilling/production methods. There are advances made in ocean engineering which include a variety of innovative offshore structure designs, ranging from fixed platforms to floating platforms. Some of these structures include the deep-water semisubmersible platforms, jack-up rigs, floating offshore wind turbines (FOWTs), FPS (floating production systems) units.

Vortex-Induced Motions of Floating Offshore Wind Turbine Structures
The ‘Green Shift’ from fossil energy (coal, oil and natural gas) to renewable energy (sunlight, wind, waves and tide) is now a global trend. DNV forecasts that by 2050, the installed floating global wind capacity will have grown from today’s 100 megawatts (MW) to over 264 gigawatts (GW), so that 2% of the world’s electricity demand can be supplied by cost-efficient and dependable floating offshore wind. Floating offshore wind is considered to be a viable solution at water depths exceeding 50 to 60 m with abundant wind resources. As a fast-evolving technology, it has the potential for less foundation material, shortened installation cycle and decommissioning, and additional wind power generation.

Climate and Surfing
Surfing is one of the most popular activities in coastal tourism resorts. However, the sport depends strongly on the met-ocean weather conditions, particularly on the surface wind-generated waves that reach the coast.

Key Technologies for Offshore Wind Power in China
Offshore Wind Power (OWP) has gained prominence in China’s national energy strategy. However, the levelized cost of electricity (LCoE) of wind power must be further reduced to match the average wholesale price. The cost-cutting and revenue-generating potential of offshore wind generation depends on technological innovation.
