Torstein Hagen's Viking Cruises is trying to win approval to amend elements of two notes issues worth $800m in total.

It said it wants to make certain changes to the $250m series due in 2025 at interest of 6.25% and the $550m issue due in 2027 at interest of 5.875%.

The proposed amendments to the 2025 notes would "substantially conform certain covenants, definitions and other terms in the 2025 indenture with those contained in the 2027 indenture."
