India's Cochin Shipyard (CSL) is moving closer to an IPO after filing a red herring prospectus.

The deal -potentially in August - could be worth anywhere from INR 10bn to INR 15bn ($230m), according to various reports.

The state-owned shipbuilder's chairman and managing director Madhu Nair told BusinessLine that the proceeds will go towards a new large drydock and the setting up of a new international shiprepair facility.
