In yet another case of giant-eating-giant consolidation, Rolls-Royce Plc has made a surprise $933 million agreed cash offer for Vickers Plc, in a move aimed at making Rolls-Royce the global leader in marine power systems. The acquisition would place a significant portion of marine propulsion products - including the Ulstein, Aquamaster, Kamewa, Rauma, Brown Brothers and Mitchell Bearings brands - in one company's control, affecting operators of all vessel types, from VLCCs to tugboats. Ironically, the move comes just as Vickers put the finishing touches on its own revived industrial empire, by acquiring several marine propulsion equipment suppliers in order to dominate a once fragmented piece of the international maritime market.
