Carnival Corp has a new chief operating officer, overseeing in part its maritime and ports operations.

The New York-traded, Miami-based cruise major announced on Friday that Josh Weinstein would take the post immediately after three years overseeing Carnival UK, which operates brands P&O Cruises and Cunard.

"Josh is a highly talented executive with extensive industry experience and institutional knowledge who will add important strength to our senior leadership team," said Carnival chief executive Arnold Donald.
