  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 …

  Hydrodynamic Analysis of Symmetrical Naca Airfoils: A CFD Simulation Approach

  By Kalyan Das, Sahul Muhique, Kalyan Kalita

  Abstract: This study presents a comprehensive numerical investigation of the hydrodynamic characteristics of selected NACA airfoil profiles using advanced computational fluid dynamics (CFD) simulations performed in ANSYS Fluent. The primary objective is to evaluate the fluid–structure interaction behavior of these airfoils when subjected to marine flow conditions relevant to offshore and submerged engineering applications. By modeling the interaction between incompressible fluid flow and various NACA geometries, the study systematically analyzes key …

  Design and Development of an Automated Robotic Algorithm for Blasting, Painting, and Barnacle Cleaning of Offshore Structures

  By Nagesh Bhadriraju, Pramodaki

  Abstract: Marine surface maintenance tasks such as barnacle removal, abrasive blasting, and protective painting are traditionally carried out using manual methods that are labor-intensive, hazardous, and prone to variability in quality. These challenges are particularly significant for offshore structures, where harsh environmental conditions and restricted accessibility increase operational risks and maintenance costs. This paper presents the design and evaluation of an autonomous robotic system for automated surface preparation and coating of …

  Design and Performance Considerations for Buildings in Coastal and Offshore Environments

  By Birendra Kumar Singh

  Abstract: Buildings near coastal and offshore regions are exposed to extreme wind and seismic forces that govern structural design. In this study, a simplified assessment of wind and earthquake loads acting on a multistorey coastal building is presented. A wind velocity of 400 km/hr. is considered to represent severe cyclonic conditions. Using a unit weight of air of 12 N/m³, the cumulative wind thrust acting over a building height of 40 …

  Embracing Health, Safety, and a Greener Environment in the Construction of Offshore Structures

  By Oluwadare Joshua Oyebode, Saibu Amodu Ahmed, Sunday Apeh, Sunday Egbiki, Akinniyi Tunde Akinyemi

  Abstract: Offshore infrastructure (oil and gas platforms, offshore wind farms, subsea cables, ports, and associated works) plays a vital role in energy, communications, and trade. However, construction activities offshore create complex safety, public health and environmental risks from worker injuries and exposure to hazardous substances, to marine pollution and ecosystem damage with downstream human health effects. This paper reviews the hazards, regulatory and management frameworks, lessons from major incidents, and practical …

  Aerodynamic Effects of Wind on Multi-Story Structures: A Height- and Terrain-Based Analysis

  By Monali Raghunath Bhale, R.S. Londhe

  Abstract: Wind loads are a critical consideration in the structural design of buildings, with direct implications for safety and serviceability. This study investigates the aerodynamic behavior of reinforced cement concrete (RCC) buildings under varying heights and terrain conditions, in accordance with IS: 875 (Part 3): 2015. 12 structural models representing 20 m, 35 m, and 50 m tall buildings were analyzed using extended three-dimensional analysis of building system (ETABS) across four …

  Analysis of the Impact of Seabed Earthquakes on Coastal Structures and Foundation Design

  By Birendra Kumar Singh

  Abstract: Earthquakes in the seabed occur with varying magnitudes. Seabed earthquakes cause a rapid rise in water levels, which can lead to flooding and structural damage. Therefore, when designing buildings near the seashore, it is essential to account for the additional load on columns due to water thrust. Earthquakes occurring at the seabed generate intense ground acceleration of varying magnitudes, significantly affecting water levels and inducing destructive flooding along coastal regions. …
