Mooring Failure Analysis of Semisubmersible Floating Offshore Wind Turbines Considering Mooring Redundancy at Each Azimuth Angle

open access: yesJournal of Marine Science and Engineering
Semisubmersible floating structures are becoming the predominant understructure type for floating offshore wind turbines (FOWTs) worldwide. As FOWTs are erected far away from land and in deep seas, they inevitably suffer violent and complicated sea ...

Balancing forage and fear: How people, environment and predators shape reindeer grazing in the Fennoscandian tundra

open access: yesPeople and Nature, EarlyView.
Abstract The long history of reindeer herding in Fennoscandia has shaped the mountain tundra by influencing its productivity, nutrient and carbon cycling and vegetation structure. By partly limiting shrub expansion, extensive reindeer grazing contributes to ecosystem resilience and helps mitigate climate change effects.

A Flexible Quasi-Static Mooring Design Optimization Method for Floating Structures

open access: yesJournal of Marine Science and Engineering
This paper presents a flexible and efficient design method for optimizing the mooring systems of floating structures. Mooring system optimization is challenging because of the strong nonlinearity of mooring system behavior and the many technical ...

Comparison and Sensitivity Investigations of a CALM and SALM Type Mooring System for Wave Energy Converters

open access: yesJournal of Marine Science and Engineering, 2014
A quasi-static analysis and sensitivity investigation of two different mooring configurations—a single anchor leg mooring (SALM) and a three-legged catenary anchor leg system (CALM)—is presented.

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

open access: yesPeople and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Hydrodynamic Analysis of Mooring Lines of a Floating Seawater Desalting Equipment

open access: yesHaiyang Kaifa yu guanli, 2022
Referring to the specific parameters, working environment and cabling mode of a seawater desalination device, this paper used OrcaFlex, a large-scale marine hydrodynamic analysis software, to establish a hydrodynamic analysis model of the mooring system ...

Hydrostatic Mooring System [PDF]

open access: yes, 2000
This report is a summary of the following topics of the first quarter of 2000: (1) Han Padron Associates (HPA) provided conceptual structural design of the mooring buoy; and (2) they completed partial review of the HPA design and designed the sealing elements.

Impact of data assimilation on Arctic sea‐ice thickness variability and its coupling with atmospheric forcing

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We document for the first time how the assimilation of CS2SMOS observations improves the model representation of Arctic sea‐ice thickness (SIT) and its variability: biases are reduced (top row), while excessive variability in the Beaufort Sea and lack of variability in the ice pack are both corrected (bottom row).

Dynamic Analysis of Embedded Chains in Mooring Line for Fish Cage System

open access: yesPolish Maritime Research, 2018
Investigation of the embedded chains in soil starts to play an important role in understanding the structural performance of mooring system, when the embedded anchors will be employed to sustain large loads with the gradually growth of installation depth
