| Source measurement | Fabian Wrede class ships are built with steel hull and aluminium superstructure . One 500 kW CAT C 18 engine driving a single screw provides the propulsion for the vessels, with a bow thruster provided for increased maneuverability. An auxiliary 38 kVA diesel generator is also carried. The ships are manned with a maximum of eight seaman students and four instructors and crew members. Intended as purpose-built training ships, the internal layout and equipment of the bridge is designed similar to larger warships. The engine room is built spacious enough for several students and the mess can be converted to a class room.[source]Fabian Wrede-class training ship · Design; only the objects and conditions stated in this passage | The Sandhayak -class survey ships are a series of eight vessels built by Garden Reach Shipbuilders and Engineers (GRSE), Kolkata and Goa Shipyard , Vasco for the Indian Navy .
