Berg Propulsion’s feathering controlled pitch propeller has been selected by United Faith (Hong Kong) Group subsidiary Celestone Marine Engineering Co. Ltd, as part of a deal that looks to equip up to four state-of-the-art semi-submersible heavylift vessels with complete propulsion systems. The deal, which includes firm orders covering two vessels, plus options to equip a further two in the months ahead, will see installation of combination propulsion systems on each ship, involving traditional diesel engine plus electrically powered Azimuth driver systems from Berg, the Berg CPP with feathering capability, two Berg Azimuth Thrusters (BAT), and two Berg CP tunnel thrusters. The estimated delivery time for the Berg equipment is August 2011.
