Scour Mechanism Induced By Propeller Flow Near A Quay Wall

Coastal Engineering Proceedings, 2018
Increasing ship dimensions in recent years cause structural instability due to the scouring problem during berthing and unberthing maneuver of the vessels. The propeller jet has 3D flow area and high velocities that may cause erosion problem around the berthing structures in three ways. These are; a) On a slope, b) At the toe of vertical wall, c)

Feasibility of solid waste-based geopolymers for anti-scouring protection of offshore scour pits: Macro-performance, micro-characterization, and sustainability

Case Studies in Construction Materials
This study proposes a method for anti-scour protection of offshore monopile foundations by using solid waste-based geopolymer materials. Fly ash (FA) and soda residue (SR) were mixed with sodium silicate (SS) solution to prepare fly ash-soda residue ...

Interplay Between Green Investment and Market Price Premia in Global Shipping

International Journal of Finance &Economics, EarlyView.
ABSTRACT Existing research emphasises that the driver of green investment is its future profitability. This paper shows that other investors' decisions also influence green investment. We take the example of scrubber installation in shipping, which is optional by regulation but has an established market for trading its underlying asset.

Radar imaging mechanism of the Birkenfels wreck in the southern North Sea [PDF]

, 2010
Varying tidal currents close to the sea bed cause sediment motion around wrecks leading to formation of scour holes and sand ribbons. Consequently, scouring destabilizes the position and shape of wrecks. Changing water depths above the shallowest parts

Sediment patterns near a model patch of reedy emergent vegetation [PDF]

, 2012
This laboratory study describes the sediment patterns formed in a sand bed around circular patches of rigid vertical cylinders, representing a patch of reedy emergent vegetation. The patch diameter was much smaller than the channel width.

Influence of Scour Protection on the Vertical Bearing Behaviour of Monopiles in Sand

Water
Extensive studies have been performed on the effectiveness of scour protection against scour erosion progression. But there is little research to date evaluating the effect of scour protection on vertical resistance behaviour of monopile foundations ...

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,

Investigation of the local scour depth of a pile foundation on the migrating sand waves seabed in the western South China Sea

Frontiers in Earth Science
In the western South China Sea, the diversity and complex genesis of sand waves lead to difficulties in measuring the actual scour depth of offshore wind turbine foundations. The present study employs methods such as in-situ multibeam echo sounding along

The Mechanical Properties of Scoured Fabrics Under Various Conditions

Textile Coloration and Finishing, 2008
Three kinds of 135D/108F ITY were produced from raw yarn 85D/72F + SDY 50D/36F with interlacing pressure 1.5kg/cm 2 , 2.5kg/cm 2 , 3.5kg/cm 2 respectively. 72 kinds of sized yarns were manufactured from three ITYs by altering sizing speed, sizing temperature and sizing tension.
