Indian firms are increasingly getting into ship building and repairing as shipbuilding orders are expected to rise significantly to meet the boom in seaborne trade and increased offshore oil exploration. The local industry is expected to expand to $20b by 2020 from close to $5b now, a report by maritime consultants i-maritime Consultancy Pvt Ltd said, which is about 1 percent by value of total global shipbuilding orders. Besides subsidies given by the Indian government to local shipbuilders, which is a big incentive, a major part of the world shipping fleet is very old and due for replacement, Chief Financial Officer Dhananjay Datar of ABG Shipyard said.
