Qatar Navigation (Milaha) has more than doubled its container shipping business - and its fleet - over the last two years.

"Given the rising demand for our services, we have been increasing our fleet steadily with the total number of vessels increasing over 100 units which are operating across multiple sectors," CEO Abdulrahman Al-Mannai told The Peninsula.

"Out of that, some 15 ships are dedicated to container shipping service, which has more than doubled compared to seven vessels used for the same purpose just about two to three years ago."

The country has opened a new port at Hamad, leading Milaha to use bigger vessels.

New routes and feeder services have also started, including one between Bangladesh and Sri Lanka.

"It has been a steady growth for us. We are also studying some destinations and looking for opportunities to open new shipping lines and other services,' Al-Mannai said.

But he added that the company has enough tankers and gas carriers for current demand.

"We have a much diversified businesses within the shipping industry," he said.

"So we always look in the market for opportunities to acquire, lease or charter vessels, which depends on the requirement and demand from our customers."
