HOUSTON (Reuters) - Hess Corp ( HES ) on Tuesday approved the company's $53 billion merger with the No. 2 U.S. oil company Chevron ( CVX ), according to preliminary results of the vote.

The merger required a majority vote to approve the deal by a majority of Hess' 308 million shares outstanding to pass. The company did not immediately provide the vote tally.

Chevron ( CVX ) offered to acquire Hess last October in a move to gain a foothold in oil-rich Guyana's lucrative offshore fields. The deal has been stalled by an ongoing review by the U.S. Federal Trade Commission and clouded by an arbitration claim filed by Hess' partner in Guyana, Exxon Mobil ( XOM ) and CNOOC.

The result is a win for Hess CEO John Hess and puts to rest claims by some shareholders who wanted additional compensation for the delay in closing the sale. Exxon's arbitration could push the deal's closing into 2025.

"Assuming Chevron ( CVX ) wins the arbitration from Exxon or finds a settlement, the transaction is now going to happen," said Mark Kelly, an analyst with financial firm MKP Advisors.
