Royal Caribbean Cruises is seeking an undetermined amount of debt to take care of a mulitimillion-dollar loan set to mature in 2018.

The New York-listed cruiseship owner has put out a prospectus seeking senior notes to repay a $290m unsecured term loan due next year. It will also be used to pay back parts of unsecured revolving facilities due 2020 and 2022.

Any funds remaining will go toward general corporate purposes.

The notes will begin accruing interest later this year and interest payments will be made twice a year starting in 2018.

Royal Caribbean's total debt stands at $7.6bn, down from $9.7bn a year earlier.

Its market cap is $26.6bn based on $214.1 million outstanding shares as of 31 October.
