In the second such incident in less than a month, a Mexican energy company said two workers died after an accident on an offshore oil rig.

Petroleos Mexicanos, known also as Pemex, said the accident at its Troll Solution field was tied to a leg malfunction on a rig provided by services company Typhoon Offshore. Two workers from an undisclosed company died as a result of the accident and one other was injured.

Nearly 100 contractors and three Pemex workers were evacuated from the rig.

"Operations are developing normally, and the accident did not affect oil production," the Mexican oil company said in a statement.

Pemex in April reported a blaze at its Abkatun platform in the Bay of Campeche in the southern waters of the Gulf of Mexico. Four workers were confirmed dead and more than a dozen others were injured.

The company produced more than half of its 2.3 million barrels per day reported since the end of February from the southern Gulf of Mexico.

After reforms were enacted last year, Mexican President Enrique Peña Nieto set a goal of producing 3.5 million barrels of oil per day by 2025, which would be a 40 percent increase from 2013 levels. The government said Tuesday it would offer more than a dozen new parcels in mature waters of the Gulf of Mexico up for auction later this year.
