EASY INSTALLATION FOR NEWBUILDINGS AND RETROFITS
Newbuildings Installation of the Becker Mewis Duct® can easily be performed during the docking or block stage with minimal effort on part of the shipyard. The yard is able to implement the installation in the production schedule. The Becker construction team adapts the interfaces of the Becker Mewis Duct® and the ship according to the ship’s steel structure.
Retrofits
The Becker Mewis Duct® can be retrofitted during regular dry dockings or even intermediate dry dockings, the propeller does not have to be dismantled for this. Becker’s expertise ensures that installation is performed as quickly as possible, taking five days on average. Installation is carried out by the yard under Becker’s supervision to ensure professional installation. The Becker Mewis Duct® design provides the highest strength and stiffness in accordance with classification societies.
A RETROFIT SUCCESS
Our Becker Mewis Duct® references span all vessel types – demonstrating reliable CO₂ reduction and energy efficiency.

The Becker Mewis Duct® straightens the hull’s wake, accelerates the flow towards the propeller and usually produces additional forward thrust.
An optimised flow field behind the duct significantly reduces the hub vortex, leading to improved thrust and flow towards the rudder.
Due to individually placed fins, a counter-rotating pre-swirl is generated, optimising the loads on the propeller blades.
