Investigation into Fishtailing Effect of Oil Tankers Moored at Pile-Founded Column Single-Point Mooring (SPM) Systems

open access: yesJournal of Marine Science and Engineering
Targeting the “Fishtailing Effect” associated with shallow-water, pile-founded column single point mooring (SPM) systems, this study investigates the vessel’s motion characteristics under multiple operational scenarios using a numerical calculation ...

Experimental and Modeling Investigation of Seawater Hydrolysis Effects on Aramid Fiber Rupture Behavior

open access: yesJournal of Polymer Science, EarlyView.
Hydrolytic aging in seawater produces markedly different mechanical responses among commercial Aramid fibers. While some fibers exhibit progressive degradation, others maintain stable or even improved tensile behavior. Experimental yarn‐scale testing combined with mathematical degradation modeling and Arrhenius‐based lifetime prediction provides new ...

Open letter: The need for a site‐based biodiversity standard measuring and certifying impacts from nature‐based projects

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.

The Dynamics of a Forced Moored Sphere in Oscillatory Waves

open access: yesNIPPON SUISAN GAKKAISHI, 1985
A floating fisheries bank is a floating body of a distinctive shape, which is moored by a single line in the middle layer of sea. Its function is to gather the migratory fish and surface and middle layer fish. Though they were developed only a few years ago, many floating fisheries banks are being utilized and they are regarded as highly efficient, but

Modulation of wind drag by tidal currents in an embayment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

The Calculation Method of the Maximum Mooring Force of an External Turret Mooring System

open access: yesJournal of the Society of Naval Architects of Japan, 1991
Floating production, storage and offloading units (FPSO) and floating storage and offloading units (FSO) have been and will be built for small or medium size oil fields. Recently the external turret mooring systems (ETM system) for FPSO/FSO are increasing in number, because of easy installation onboard, redundancy of mooring chain (i. e.

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).
