US owner Seacor Marine has snapped up three platform supply vessel (PSV) newbuildings in China.
The New York-listed company said it is paying $46m for the ships from the Cosco Zhoushan shipyard.
It will fork out 30% in cash and the rest under a four-year deferred payment agreement.
Half of the cash part is due in the first quarter of 2019, with the remainder being paid on each delivery.
