STX OSV has played down talk that its parent STX Europe plans to sell off a 20% stake in the Singapore-listed arm. STX OSV said it understood STX Europe planned to comply with a 12-month lock-up period that ends on 12 November this year. “STX OSV further understands from STX Europe that as of to date, STX Europe has not made any firm plans in relation to its stake in STX OSV,” the company said.
