Japan's K Line has arranged financing worth JPY 45bn ($407m) that matures over 35 years.
The subordinated loan means creditors will rank behind others in the queue for their money should something go wrong at the giant owner.
K Line said the cash will develop its core businesses through its ongoing "rebuilding portfolio" strategy, with the aim of expanding stable income and achieving sustainable growth.
"As one of the measures to accomplish the goal, the group has decided to raise funds through the subordinated loan, which is a financing method that enhances financial foundation while maintaining capital efficiency," it added.
The term ends in March 2054, but the owner can pay it off early from 2024.
It can also defer interest payments at its own discretion.
Lenders are Mizuho Bank, Development Bank of Japan and Sumitomo Mitsui Trust Bank.
Earlier this month, K Line revealed plans to slash its chartered fleet to boost earnings as losses were forecast to approach $900m this year.
The "structural business reforms" include the cancellation of "uneconomical" charters for boxships and small and medium-sized bulkers worth JPY 50bn.
It also wants to reduce market exposure and will examine 25 of its fleet-types in the 12 months to 31 March next year.
