Germany's KfW IPEX-Bank is providing EUR 30m ($34m) to finance Royal Arctic Line's feedership newbuidings in Spain.
The Greenland owner ordered the two 1,100-teu vessels this year at Zamakona for delivery in 2020.
The financing is backed by cover from the Spanish export credit insurer CESCE and includes funds from the Spanish CIRR (commercial interest reference rate).
KfW said the vessels will use a "high amount" - 30% - of German components.
The ships will be used to move cargo to remote towns and settlements along the Greenlandic coast that are not connected by land.
"We are pleased that our financing will support our long-standing and valued customer Royal Arctic Line with its fleet renewal plan," said KfW IPEX-Bank management board member Andreas Ufer.
"At the same time, we are contributing to supplying the Greenlandic population and to modernising the maritime infrastructure in the European North Sea."
KfW's most recent financing for RAL was for a 2,150-teu boxship to improve liner traffic between Denmark and Greenland from 2019, together with two sisterships for Iceland's Eimskip.
