PENSIONERS will be barred from the casino on board Clive Palmer's re-imagined Titanic.

The mining billionaire on Tuesday gave a glimpse of the first drawings of Titanic II, a modern version of the original ill-fated liner.

Mr Palmer says Titanic II will have a casino, but he doesn't want it to suck money from passengers who can't afford to lose it.

"There will be strict restrictions," he told reporters.

"No pensioners will be allowed to go.

"There will be some sort of screening to make sure people who do go there can afford to."

Mr Palmer imagines those who travel with a first-class ticket will be able to afford to go to the casino but perhaps not those in third class.

But he says he'll be buying a third class ticket.

"It's more fun to dance with an Irish drunk than to sit in a casino," he said.

The Titanic II will also have a new "safety deck" that Mr Palmer says will have "proper life boats", safety chutes and slides to make it compliant with today's regulations.

The drawings depict nine decks complete with first, second and third-class, officer and crew accommodation.

From deck D upwards, engineers Deltamarin have managed to keep the public rooms, passenger stairs, cabins and features in similar locations as in the original ship.

The board of his shipping company Blue Star Line is yet to approve the final design.

The first voyage is set for late 2016.
