In a step toward a limited, late summer cruise season, Norwegian Cruise Line has signed an agreement with the state of Alaska and several of Alaska’s port operators, according to APM.

Gov. Mike Dunleavy’s office announced an agreement on Thursday which lays out a set of protocols to guide the resumption of Norwegian’s cruises in Alaska. All cruise companies who want to operate in the U.S. this year have to enter into similar agreements with U.S. ports to sail with the Centers for Disease Control and Prevention’s blessing.

The first Norwegian ship would set sail for Alaska in early August. Weeklong voyages would run through late October. The agreement said one Norwegian ship would run through Southeast Alaska once a week.
