Abstract Bunker fuel prices constitute a major component of maritime transport costs, representing 30–70% of total operating expenses and critically influencing competitiveness, planning, and regulatory compliance in g...

With the further development of marine exploration in China in recent years, higher requirements are put forward for the capacity of the soil and cyclic loading effect for the offshore engineering. Due to the difficulty ...

Since 2020, offshore wind turbine prototypes have experienced a substantial increase in size. At the same time, wind turbine design standards have not specified requirements for marine atmospheric turbulence. The impact ...

Floating offshore wind turbines (FOWTs) raise concerns among coastal communities due to their potential impacts on marine biodiversity and fisheries. This issue is particularly striking in France, where the government is...

The CU triaxial tests and ring shear tests on interface between steel pipe pile and soil of a kind of intact marine soft clay with medium structure are carried out under influence of shear strain rate, and the variations...

The increasing attention to land–sea interactions in spatial planning highlights persistent difficulties in integrating terrestrial and maritime governance, particularly in tourism-intensive coastal areas where environ...

In order to improve the problems of the electro-osmosis chemical grouting method, the tests need to be carried out for proper grouting concentration and methods. The electro-osmosis chemical grouting with different grout...

Sailing yachts can achieve operationally zero-emission propulsion by integrating solar photovoltaic (PV), wind and hydrokinetic generation with battery-electric drive systems. This study applies a systems engineering mod...

Abstract Many sulfated polysaccharides (SPSs) possess useful physicochemical properties and biological activities and are widely used in industry. Currently, major SPSs are derived from livestock and marine organisms. To...

The transport industry has recently shown significant interest in unmanned surface vehicles (USVs), specifically for port and inland waterway transport. These systems can improve operational efficiency and safety, which ...

In marine science and engineering, growing volumes of imaging data are used in exploration and monitoring. The process of manual annotation of this data (i.e. marking and describing objects of interest with labels), to e...

Abstract Rapid population growth and a corresponding increase in the demand for animal-derived proteins have led to food supply challenges and the need for alternative and sustainable meat production methods. Therefore, ...

Abstract Understanding and controlling the marine degradation of biodegradable polymers is crucial for sustainable materials engineering and pollution prevention. However, a unified interpretive method that links multisc...

Calcareous sand is a special kind of geotechnical sand which consists of much carbonate. Based on the remains of the original marine organisms, the calcareous sand grains have irregular shapes and contain inner pores. Th...

Traditional electromechanical cleaning equipment remains overly dependent on human assistance when performing cleaning tasks in unstructured marine environments. With the rapid development of robotic technologies, underw...

Abstract Current studies of a seawater axial piston pump mainly solve the problems of corrosion and wear in a slipper pair by selecting materials with corrosion resistance, self-lubrication, and wear resistance. In addit...

Abstract Sodium carbonate-activated slag mortar (SCASM) exhibits the advantages of low shrinkage, high strength in late age, and low-cost and carbon emissions. However, its microstructure is relatively porous due to the ...

Abstract Cam-lobe radial-piston hydraulic motors are widely used as rotation driving units for various marine machinery owing to their ultrahigh output torque (more than 100 kN m). A multi-row cam roller bearing (MCRB) i...

The objective of this study is to enhance the energy efficiency and environmental safety of boiler plants and engines equipped with waste heat recovery boilers. This objective is achieved by utilizing water-fuel emulsion...

Currently, subsea mining is primarily limited to sea sand extraction and deep-sea mining that focus mainly on mining activities at the seabed surface. These conventional methods not only pose significant environmental ri...
