Carnival Corp. says its second-quarter profit dipped 4.5 percent, partly on higher fuel costs. But revenue climbed as it added two new ships to its fleet.

For the three months that ended in late May, the cruise operator had net income of $252 million or 32 cents per share.

That's down from net income of $264 million, or 33 cents per share last year.

But revenue rose for the second consecutive quarter, to $3.20 billion. That's up more than 8 percent from $2.95 billion during the same quarter in 2009.

The company's per-share earnings were better than Wall Street forecasts, but analysts expected higher revenue.

The Miami company owns Carnival, Princess and Holland America cruise lines.
