Efficient preliminary floating offshore wind turbine design and testing methodologies and application to a concrete spar design [PDF]

, 2015
The current key challenge in the floating offshore wind turbine industry and research is on designing economic floating systems that can compete with fixed-bottom offshore turbines in terms of levelized cost of energy. The preliminary platform design, as

Mooring system diagnosis and structural reliability control for position moored vessels [PDF]

Control Engineering Practice, 2015
Abstract Early diagnosis and fault-tolerant control are essential for safe operation of floating platforms where mooring systems maintain vessel position and must withstand environmental loads. This paper considers two critical faults, line breakage and loss of a buoyancy element and employs vector statistical change detection for timely diagnosis of

Analysis of Platform Dynamic Response With a 3 × 3 Mooring System for the DTU 10 MW Wind Turbine Based on OpenFAST

Shock and Vibration
A novel 3 × 3 mooring system was designed for the DTU 10 MW wind turbine based on the floating platform OOStar. This new mooring system was compared with the original mooring system using OpenFAST.

Measuring the impact of observations on the predictability of the Kuroshio Extension in a shallow-water model [PDF]

, 2012
In this paper sequential importance sampling is used to assess the impact of observations on a ensemble prediction for the decadal path transitions of the Kuroshio Extension (KE). This particle filtering approach gives access to the probability density of

Coupled Responses and Performance Assessment of Mooring-Connection Systems for Floating Photovoltaic Arrays in Shallow Waters

Journal of Marine Science and Engineering
Offshore floating photovoltaic (FPV) platforms are usually deployed in shallow waters with large tidal variations, where the modules of FPV are connected with each other via the connectors to form an array and mounted to the seabed via the mooring system.

Current structure in the Rhine region of freshwater influence [PDF]

, 1997
Observation with HF radar, ADCPs and conventional current meters in the Rhine ROFI system in the North Sea indicate that the dominant currents are due to tidal flow, with important contributions from winds and density-driven circulation.
