Effect of Water Depths on the Hydrodynamic Responses of an FPSO Platform

open access: yesMATEC Web of Conferences, 2018
Ship-shaped Floating Production Storage Offloading platforms (FPSO) are commonly used in the production of oil and gas in offshore deepwater regions. The vessel is held in place by mooring lines anchored to the seabed during operation, either in spread ...

The variability of the surface wind field in the equatorial Pacific Ocean: Criteria for satellite measurements [PDF]

open access: yes, 1984
The natural variability of the equatorial Pacific surface wind field is described from long period surface wind measurements made at three sites along the equator (95 deg W, 109 deg 30 W, 152 deg 30 W). The data were obtained from surface buoys moored in

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

open access: yesShock 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.

Evaluating the Validity of Quasi-Static Analysis for Prediction of Vessel Mooring Line Forces

open access: yesInternational Journal of Maritime Technology, 2013
Quasi-Static analysis of moored vessels is vastly used for engineering designs, as a substitute to the numerical simulation of dynamic mooring analysis. Yet, the level of validity of the results of quasi-static analysis is a matter of discussion.

Time-domain dynamic response analysis of progressive mooring failure for deep-sea semi-submersible platforms

open access: yesJournal of Ocean Engineering and Science
Deepwater semi-submersible platforms play a pivotal role in the exploration and exploitation of marine resources. The ''Deep Sea No.1″ semi-submersible platform in the South China Sea serves as the reference case for numerical simulations.

Evidence of the selection of tidal streams by northern rock sole (Lepidopsetta polyxystra) for transport in the eastern Bering Sea [PDF]

open access: yes, 2009
Depth data from archival tags on northern rock sole (Lepidopsetta polyxystra) were examined to assess whether fish used tidal currents to aid horizontal migration.
