S Surat is the fourth ship of the indigenously designed and constructed Project 15B (Vishakhapatnam Class) destroyers.
Mazagaon Dock Limited (MDL) in Mumbai
ip has been constructed using innovative block construction methodology, wherein the ship’s hull has been assembled at distinct geographical locations before being integrated at the Mazagon Dock Limited(MDL).
st of INS Surat depicts the renowned Hazira lighthouse. It was built in 1836, at the southern entrance of the Gulf of Khambhat. It was among India’s earliest lighthouses.
crest also features an Asiatic lion (state animal of Gujarat) representing the majesty and strength of ships.

incorporates advanced design concepts such as state-of-the-art weapons and sensors, advanced stealth features and a high degree of automation for improved survivability.
reen infrastructure refers to the restoration of natural resources like forest covers and wetlands, which help in management of excess rainwater by aiding natural percolation and natural runoff.
rey infrastructure refers to human-engineered infrastructure like storm water drains, waster water treatment plants and dams, created for management of excess rainwater.
artificial structures of drainage have several health related challenges like breeding of harmful bacteria like E. Coli, dengue mosquitoes.
Construction of dams, large waste water treatment plants have associated human cost of displacement. For Ex- Narmada Dam protests.
nterference with the natural pattern of drainage- These grey infrastructures have interfered with the natural pattern of drainage and have led to situations of urban floods. Ex- Bengaluru, Hyderabad and Chennai floods have occured due to encroachment of natural wetlands and construction of storm water drains in its place.
unding and public investment– Large investments are needed in building artificial water conservation infrastructures.
egular maintenance– Regular maintenance of these artificial structures is expensive and cumbersome as compared to natural conservation infrastructures like wetlands and forest.
way forward in excess rain water management must be on the integration of green and grey infrastructures. But our focus must be on improving the green infrastructures first, as far as possible.
