Tidewater has completed its $190m takeover of Swire Pacific Offshore.

The Houston-based, New York-listed offshore support vessel (OSV) giant first announced the acquisition in March, adding 50 ships to its fleet, bringing the total to 174 offshore supply vessels.

“We are pleased to announce the closing of this acquisition and we are excited to welcome our new employees and customers to Tidewater,” chief executive Quintin Kneen said in a statement.
