What is the News?
The Indian Navy has launched Sandhayak, a survey vessel, in Kolkata.
What is Sandhayak?
‘Sandhayak’ is one of the first of the four Survey Vessels (Large) projects being built for the Indian Navy.
Developed by: Defence Public Sector Undertaking, Garden Reach Shipbuilders and Engineers (GRSE) Limited.
Purpose:
- To conduct a full-scale coastal and deep-water hydrographic survey of ports and harbors and determination of navigational channels and routes.
- To collect oceanographic and geophysical data for defense as well as civil applications and
- To perform roles such as Search and Rescue and Disaster Relief, besides serving as hospital ships with limited facilities during emergencies.
Name: The ship has taken its name from the first ship of the erstwhile Sandhayak-class survey ships.
Features: The vessel will have over 80% indigenous content. It is also propelled by two marine diesel engines combined with fixed pitch propellers and fitted with bow and stern thrusters, enabling it to manoeuvre at a low speed during surveys.
