  Detection and Assessment of Structural Weaknesses in Existing Offshore Structures

  By Sanchita Hiwrale, Kunal Waghule, Om Jahagirder, Tejas Tirukhe, Anuradha Kalamb, Hashmi S. Mujahid

  Abstract: The structural integrity and serviceability of existing structures may deteriorate over time due to aging, environmental exposure, material degradation, overloading, inadequate maintenance, and repeated operational stresses. Early identification of structural deficiencies is essential for preventing progressive damage and ensuring safe and reliable performance throughout the service life of a structure. This study presents a systematic structural condition assessment of an existing structure using visual inspection and non-destructive testing (NDT) techniques. …

  Structural Design of Offshore Structures: A Review of Indian and International Standards

  By Er. Syed Shafahaduddin Quadri

  Abstract: Offshore structures—including fixed steel jackets, topside modules, offshore wind turbine support structures, and floating systems—are designed to withstand combined gravity, environmental, seismic, and operational loads under substantial uncertainty and limited access for inspection and repair. Structural design practice has historically relied on internationally recognized standards, particularly the American Petroleum Institute’s API RP 2A, the International Organization for Standardization’s ISO 19900 series, including ISO 19902 for fixed steel structures, and Det …

  Grid Sensitivity and Its Impact on the Hydrodynamics of a Submerged Vessel

  By Sahul Muhique, Kalyan Kalita, Kalyan Das

  Abstract: Accurate prediction of hydrodynamic characteristics is essential for the design and performance assessment of underwater vehicles and offshore structures. Computational fluid dynamics (CFD) has emerged as an effective tool for analyzing fluid flow behavior around submerged bodies, enabling detailed evaluation of pressure distribution, drag forces, and flow patterns. In this study, the effect of mesh refinement on the hydrodynamic analysis of a DRDC-STR submarine nose section was investigated using ANSYS …

  Comparative CFD Analysis of Major and Minor Aerodynamic Modifications for Tall Building Shapes under Wind Loading

  By Tanmay Rajiv Jadhav, Yuwaraj M. Ghugal

  Abstract: Aerodynamic performance of tall buildings is significant to structural safety and serviceability under wind. The major and minor aerodynamic changes of the tall building shape are compared with the computational fluid dynamics (CFD) simulation. The base model was a rectangle of 75 m × 75 m × 300 m. Various aerodynamic modifications of shapes were examined: circular, elliptical, tapered, twisted, rounded-corner, and chamfered-corner shapes. Simulations were carried out in the …

  From Baseline Survey to Management Plan: A Systematic Framework for Port-Specific Mitigation of Underwater Radiated Noise

  By Amit Kumar Singh, G.V.V Pavan Kumar, P. Sirisha, D.S.P Vidyasagar

  Abstract: The growing recognition of underwater radiated noise (URN) as a significant marine pollutant necessitates the development of actionable management frameworks at the port level, where noise sources are concentrated, and impacts can be particularly acute. While international guidelines exist, a standardized methodology for ports to transition from assessment to implementation is lacking, particularly in regions with high biodiversity and developing maritime infrastructure. This paper presents and demonstrates a systematic, four-phase …

  Hydrodynamic Assessment of a Proposed FSRU Development in the Visakhapatnam Outer Harbour

  By Kapil Walke, M. Phani Kumar, Prabhat Chandra

  Abstract: This study presents a detailed hydrodynamic assessment of a proposed Floating Storage andRegasification Unit (FSRU) in the Visakhapatnam Outer Harbour. A depth-integrated, two- dimensional hydrodynamic model was developed using MIKE-21 Flexible Mesh (FM) to quantify theinfluence of the terminal layout, dredged pocket configuration, and vessel presence on tidal circulation, freshet-driven flows, and extreme-event conditions. Baseline simulations were performed using existing bathymetry and operational geometries, followed by proposed configurations that included …
