“…Significant benefits brought by the increase of the wind turbine assembly capacity are the improvement of the wind energy utilization efficiency and the reduction of unit power cost. However, the increasing blade size also brings great challenges to designers and experimenters [14][15][16][17][18][19][20]. As one of the main research methods, scale model tests provide the most direct and effective means to evaluate operation performance and nonlinear phenomenon of wind turbines, obtain extreme and specific load distributions, and verify design codes.…”

“…A possible solution is to introduce non-linear mooring components in the system that provide the necessary compliance and stiffness based on the prevalent environmental conditions to reduce peak loads. 250,251 It is important to note that aquaculture systems come in several forms, with fundamental differences. The present review focuses on open aquaculture systems.…”

Offshore aquaculture has gained momentum in recent years, and the production of an increasing number of marine fish species is being relocated offshore. Initially, predictions of the advantages that offshore aquaculture would present over nearshore farming were made without enough science‐based evidence. Now, with more scientific knowledge, this review revisits past predictions and expectations of offshore aquaculture. We analysed and explained the oceanographic features that define offshore and nearshore sites. Using Atlantic salmon (Salmo salar) as a case study, we focussed on sea lice, amoebic gill disease, and the risk of harmful algal blooms, as well as the direct effects of the oceanography on the health and physiology of fish. The operational and licencing challenges and advantages of offshore aquaculture are also considered. The lack of space in increasingly saturated sheltered areas will push new farms out to offshore locations and, if appropriate steps are followed, offshore aquaculture can be successful. Firstly, the physical capabilities of the farmed fish species and infrastructure must be fully understood. Secondly, the oceanography of potential sites must be carefully studied to confirm that they are compatible with the species‐specific capabilities. And, thirdly, an economic plan considering the operational costs and licencing limitations of the site must be developed. This review will serve as a guide and a compilation of information for researchers and stakeholders.

In order to meet the needs of emergency communication for major emergency disaster rescue, a wireless emergency communication relay system based on tethered UAV platform is studied. From the perspective of practical application, the characteristics and network coverage of the emergency communication system are analyzed. The mooring UAV platform is equipped with various communication loads such as MESH(wireless grid network communication), 4G-LTE( Long term evolution fourth generation mobile communication) base station, AIS (Automatic Identification System) and so on, which are kept on the communication support ship. When the communication support ship enters the scene of maritime emergencies, the tethered UAV platform lifts off ,stays for a long time and realizes the relay communication service of various carriers within a radius of tens of kilometers through its various communication payloads, which provides key communication support for the Marine emergency communication network. The actual field test of the prototype system shows that the data transmission is stable and reliable, and the short message transmission is normal, which can meet the emergency communication demand of disaster rescue.
