Slope Stability At The Juncture Of Dredged Berth Pocket & Reclaimed Earth Embankment During Turbulence Caused by Rotation of Ship’s PropellerBy SUDIPTA CHAKRABORTY, A.R. Kambekar, Arnab Sarma Sarma
Abstract: For accepting vessels with large drafted deepening of the berth pocket at any jetty is necessary by dredging. During berthing of ships, the bed soil particles in berth pocket gets eroded due to critical velocity, due to turbulence of the sea water in the pocket, caused by propeller’s motion and also due to eddies formed during trimming of vessel. Such disturbances in bed soil particles and the energy in the …

Calculation of Element Stiffness Matrix for Finite Element Analysis of Pile Dynamic StabilityBy Sarma Arnab, SUDIPTA CHAKRABORTY, A.R. Kambekar
Abstract: For the purpose of analyzing the dynamic stability of pile structures under periodic loads, we have employed the Finite Element Method in this study. The soil modulus was assumed to vary linearly. We have formulated the Mathieu-Hill eigenvalue equation to analyze the stability and instability regions for different static and dynamic load factors. Our research provides valuable insights into the behavior of pile structures when subjected to dynamic loading. The …

Impact of Sea Level Rise due to Climate Change and Anticipated Consequence of Slamming Forces on Deck Elevation of Port Structures-An AssessmentBy SUDIPTA CHAKRABORTY, Kambekar A.R, Arnab Sarma
Abstract: The research methodologies for on climate change, particularly the deterministic factors have undergone gradual changes during last few decades in respective IPCC’s Assessment Reports. The original concept of emission scenarios (2000) was reconsidered as socio-economic scenarios till AR4, later appraised as Representative Concentration Pathways till AR5 based on Radiative Forcing, the capacity of a gas affecting the change in energy (trajectories not emissions) in the atmosphere. Lately in AR6 the …

Complexities in the Structural Behaviour of Offshore Structural Members subjected to Dynamic LoadingBy SUDIPTA CHAKRABORTY, Ajaykumar R. Kambekar
Abstract: Offshore structural members in Maritime Structures are subjected to various kinds of loading starting from Dead Load of structures and Dynamic loads from wind, waves, currents and operational loads during berthing and mooring of ships and vessels. The stability analysis of the structural members also demands an insight into the elastic properties of the founding sea bed level. Due to requirement of transport of large volume of cargoes and related …
