The Survey Vessel (Large) ships are capable of full scale coastal & deep-water hydrographic survey of Ports & Harbors, as well as of approaches & determination of navigational channels & routes. In addition, the ships are also capable of undertaking survey of maritime limits and collection of oceanographic & geographical data for Defence applications.
These ships are propelled by two Marine Diesel Engines combined with Fixed Pitch Propellers and fitted with Bow & Stem Thrusters for manevuring at low speeds during surveys. The ships are designed by the Design team of GRSE and are built & outfitted in compliance with applicable provisions and regulations of the Classification Society (IRS).
The ships are also constructed utilising the concept of 'Integrated Construction'. Accordingly, a large amount of pre-outfitting is carried out at the block stage itself.
