This study presents a detailed hydrodynamic assessment of a proposed Floating Storage and

Regasification Unit (FSRU) in the Visakhapatnam Outer Harbour. A depth-integrated, two-
dimensional hydrodynamic model was developed using MIKE-21 Flexible Mesh (FM) to quantify the

influence of the terminal layout, dredged pocket configuration, and vessel presence on tidal
circulation, freshet-driven flows, and extreme-event conditions.

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.

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.

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.

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,

Wind loads are a critical consideration in the structural design of buildings, with direct implications for safety and serviceability.
