The government has decided to impose age restrictions on ships that can be acquired or operated in India. Ships over the age of 25 will be withdrawn from service, including oil tankers, bunker barges, bulk carriers, general cargo ships except for container vessels, mini-bulk carriers, ro-ro, anchor handling tugs and some classes of offshore vessels. Most other classes, including container vessels, gas carriers and tugs, have to be withdrawn by age 30. Dredgers, meanwhile, will have a lifespan of up to 40 years.
