July 28 (Reuters) - Offshore shipment services provider Cal Dive International Inc DVR.N posted a wider-than-expected quarterly loss, hurt by a decline in demand due to the Gulf of Mexico oil spill.
“The decline in demand was primarily due to a reduction in hurricane repair work in the Gulf of Mexico and in new construction activity,” the company said in a statement.
For the second quarter, the company posted net loss of $11 million, or 12 cents a share, compared with net income of $28.6 million, or 30 cents a share, a year ago.
Excluding items, Cal Dive posted a loss of 8 cents a share.
Revenue fell 52 percent to $124.2 million.
Analysts on average were expecting a loss of 5 cents a share, before items, on revenue of $100.1 million, according to Thomson Reuters I/B/E/S.
