摘要

研究创新的大型藻类养殖对于优化农业运营、增加生物量生产、减少对生态系统的影响以及降低系统和运营成本是重要和必要的。然而,大多数大型藻类养殖系统(MFS)是固定的,需要占用大量沿海地区,需要对农场基础设施进行大量投资,并且需要高昂的肥料和锚定费用。本研究旨在建模、分析和支持一种新的二元物种自由漂浮延绳大型藻类培养概念。预期结果可以为新型MFS的设计和应用提供基础,以提高生物质产量、降低成本并减少对当地生态系统的影响。在本文中,对宽糖精和蓝囊藻进行了建模和验证,并与延绳钓相结合,以模拟二元物种MFS在美国西海岸不同生长期和相关位置的自由漂浮。数值预测表明,延绳断裂和海带支架断裂的可能性很低。然而,当延绳伸出水面时,由于静水浮力的损失导致动态载荷的瞬时变化而产生的巨大力会损坏海带。浮标-延绳接触的相互作用可能会损坏浮标,导致下沉造成系统损失。此外,海带延绳和海带与海带的纠缠可能会对海带造成损害。

Modeling and Analysis of a Novel Offshore Binary Species Free-Floating Longline Macroalgal Farming System
The investigation of innovative macroalgal cultivation is important and needed to optimize farming operations, increase biomass production, reduce the impact on the ecosystem, and lower system and operational costs. However, most macroalgal farming systems (MFSs) are stationary, which need to occupy a substantial coastal area, require extensive investment in farm infrastructure, and cost high fertilizer and anchoring expenses. This study aims to model, analyze, and support a novel binary species free-floating longline macroalgal cultivation concept. The expected outcomes could provide a basis for the design and application of the novel MFS to improve biomass production, decrease costs, and reduce the impact on the local ecosystem. In this paper, the Saccharina latissima and Nereocystis luetkeana were modeled and validated and coupled with longline to simulate the binary species MFS free float in various growth periods and associated locations along the U.S. west coast. The numerical predictions indicated the possibility of failure on the longline and breakage at the kelp holdfasts is low. However, the large forces due to instantaneous change in dynamic loads caused by loss of hydrostatic buoyancy when the longline stretches out of the water would damage the kelps. Buoy-longline contact interactions could damage the buoy, resulting in the loss of the system by sinking. Furthermore, the kelp-longline and kelp-kelp entanglements could potentially cause kelp damage.

期刊介绍: The Journal of Offshore Mechanics and Arctic Engineering is an international resource for original peer-reviewed research that advances the state of knowledge on all aspects of analysis, design, and technology development in ocean, offshore, arctic, and related fields. Its main goals are to provide a forum for timely and in-depth exchanges of scientific and technical information among researchers and engineers. It emphasizes fundamental research and development studies as well as review articles that offer either retrospective perspectives on well-established topics or exposures to innovative or novel developments. Case histories are not encouraged. The journal also documents significant developments in related fields and major accomplishments of renowned scientists by programming themed issues to record such events. Scope: Offshore Mechanics, Drilling Technology, Fixed and Floating Production Systems; Ocean Engineering, Hydrodynamics, and Ship Motions; Ocean Climate Statistics, Storms, Extremes, and Hurricanes; Structural Mechanics; Safety, Reliability, Risk Assessment, and Uncertainty Quantification; Riser Mechanics, Cable and Mooring Dynamics, Pipeline and Subsea Technology; Materials Engineering, Fatigue, Fracture, Welding Technology, Non-destructive Testing, Inspection Technologies, Corrosion Protection and Control; Fluid-structure Interaction, Computational Fluid Dynamics, Flow and Vortex-Induced Vibrations; Marine and Offshore Geotechnics, Soil Mechanics, Soil-pipeline Interaction; Ocean Renewable Energy; Ocean Space Utilization and Aquaculture Engineering; Petroleum Technology; Polar and Arctic Science and Technology, Ice Mechanics, Arctic Drilling and Exploration, Arctic Structures, Ice-structure and Ship Interaction, Permafrost Engineering, Arctic and Thermal Design.
