The Cruise, a 6-part ITV series set aboard a Princess Cruises ship, was nominated for a National Television Award in factual entertainment category.
Around 3.5 million viewers watched every episode, which gave insights into behind-the-scenes roles of the ship's 1,400-strong crew.
Viewers saw how the team works together to keep the 141,000-tonne, 19-deck ship running smoothly, preparing more than 20,000 meals a day and servicing 1,800 cabins.
A second series of The Cruise was commissioned immediately after the final episode concluded and was filmed this summer on Royal Princess, Regal Princess's sister ship.
Royal Princess is the first ship in the fleet to sail with the company's new livery, emerging from dry dock this month with a new hull design.
The second series of The Cruise will follow Royal Princess as it sails across the Mediterranean and is provisionally scheduled to air early next year.
Tony Roberts, Princess Cruises' vice president UK and Europe, said:
"The feedback from the first series of The Cruise has been overwhelming so an NTA nomination is the icing on the cake.
"I hope everyone who tuned in to watch our crew in action will spare a few minutes to vote for them as they are as fantastic off screen as they are on it."
Paul Hamann, executive producer at Wild Pictures, said:
"We are all immensely proud of the series and delighted that it has been nominated for an NTA. "It reconfirms how popular the show was and the audience's fascination with cruising."
The NTAs take place on Wednesday January 25, 2017 at the O2 London. To vote go to: www.nationaltvawards.com/vote
