Monaco-based maritime group Eneti said its $600m acquisition of offshore wind vessel player Seajacks was like “a birthday and Christmas rolled into one” as shipping industry analysts hailed a deal that propels it from nowhere to the front rank of turbine installation operators.

New York-listed Eneti will take control of Seajacks after an agreement with current owners Marubeni Corporation, INCJ and Mitsui OSK Lines, which have run Seajacks since 2012.
