While much of the oil industry is bleeding from low prices and oversupply, one segment is getting a boost.
Oil tankers, which are ships that carry oil and petroleum products, have benefited in recent years.
Nikolas Tsakos, chairman of Intertanko, the International Association of Independent Tanker Owners, and the CEO of Greece-listed Tsakos Energy Navigation (TEN), said that the low oil prices haven't been a negative.
"The lower the price of oil, the more demand for our services. So any price under $60 is a comfortable level for a lot of demand," he told CNBC's "Squawk Box." "We've seen a very good market from the end of 2014, the whole of 2015 and this year the market has been positive, however, not to the levels of 2015."
As oil becomes less expensive, demand for it tends to rise. That may not benefit producers much, but companies involved in transporting the oil can see benefits.
Tsakos noted his company has seen a large bump up in profit. In the fourth quarter of 2015, TEN said its net profit rose nearly three times on-year to $39.6 million, totting up a full year net profit of $158.2 million, up nearly five times on-year. The utilization of the company's fleet of an average of 48.6 vessels in the fourth quarter, was at 98 percent utilization, the company said.
