Abstract Methods for carbon sequestration are warranted to tackle climate change caused by greenhouse gases released from anthropogenic activities. Seaweed is a type of marine plant that utilizes dioxide photosynthesis and has substantial capacity sequestrate carbon. Despite the huge potential, long-lasting (LLCS) seaweed never been calculated throughout its whole life cycle (nursery, temporary rearing, maturation, harvesting, processing). In this paper, we use assessment (LCA) approach...
As global demand for sustainable biomass and need to mitigate warming begin rise, cultivation of seaweed has gained significant attention in recent years due its potential carbon recycling. However, limited availability suitable coastal areas large-scale led exploration offshore environments as a viable alternative. The nature many often exposes farming systems harsh environmental conditions, including strong waves, currents, wind. These factors can lead structural failures, kelp losses,...
To understand the evolution of dynamic stiffness damaged synthetic fiber mooring ropes, experimental investigations polyester and high modulus polyethylene (HMPE) ropes are systematically performed utilizing a specially designed system. An procedure is proposed test results show that increases with increasing mean load loading cycles, while decreases strain amplitude damage level. The similarity criterion derived from dimensional analysis for verified by experiments. empirical expression...
Abstract In this study, effects of damage levels fiber ropes on the performance a hybrid taut-wire mooring system are investigated. The analysis is performed using numerical floating production storage and offloading (FPSO) model with installed in 3000 m water depth. An in-depth study was conducted model, dynamic stiffness equation damaged ropes, time-domain theory, rainflow cycle counting method, linear accumulation rule Palmgren-Miner. Results indicate that, line an increasing level,...
Abstract As the market demand for seaweed products increases rapidly over last few decades, farming of has become one most economical and environmentally friendly marine operations in aquaculture. Seaweed cultivation areas are primarily concentrated nearshore at present. However, with expansion aquaculture facilities, rapid coastal development industrialization, available area is decreasing sharply. This led to being expanded deep-water regions. In addition, industry will likely transform...
The influence of mooring systems with lines different material on the dynamic response a floating wind turbine is studied using 5 MW OC4-DeepCwind semi-submersible as representative prototype in this study. Two types were designed MoorDyn module OpenFAST software (v3.1.0): one uses chains, and other hybrid line composed chains high-strength polyethylene (HMPE) ropes. A two was simulated software. results show that moored exhibited larger heave pitch motion than alone. At same time, surge...
Creep tests of high modulus polyethylene (HMPE) samples are performed to obtain the corresponding creep and creep-rupture curves. The results show that secondary stage is especially pronounced, its rate nearly constant. Based on this fact, at has been utilized as representative value each case. Therefore, similarity criterion proposed analyze relationship between engineering in laboratory tests. Besides, an empirical expression HMPE yarns account for effects both loading level test...
Granular-continuum interfaces commonly exist in geotechnical engineering practices, such as foundations, reinforcements, and soil nailing. The mechanical behaviors fabric of the interface are not only influenced by properties but interfaces, normal stresses. Therefore, a thorough understanding granular-continuum is essential to practices. This article investigates shear behavior focusing on stresses densities using three-dimensional discrete element modeling (DEM). influence zones resulting...
Abstract This article describes the model development and preliminary progress of an on-going research study on effects nonlinearities in ocean wave input power-take-off (PTO) control energy conversion system dynamics efficiency. The employed recent developments are: (1) nonlinear modeling ocean, generation propagation a basin, (2) PTO algorithm. An overview holistic analytical, numerical experimental approach/work plan is presented. To provide simple means for analysis, comparison...
