DUBAI, Aug 14 (Reuters) - Dubai contractor Arabtec ARTC.DU reported a narrower loss in the second quarter on Sunday, its seventh straight quarterly loss.

Arabtec made a net loss attributable to equity holders in the parent of 186.4 million dirham ($50.8 million) in the three months to June 30, it said in a statement.

This compares with a loss of 718.4 million dirhams in the corresponding period of 2015.

The company has been struggling with a difficult industry environment as Gulf economies slow and governments restrain spending because of low oil prices, hiring AlixPartners to help draw up a plan to revise its business and capital structure.

In June, shareholders agreed to use 1 billion dirhams of the company's statutory reserves to wipe out some of its accumulated losses. urn:newsml:reuters.com:*:nL8N18T1EK

The firm's quarterly revenue was 2.16 billion dirhams, versus 1.80 billion dirhams a year earlier.
