MOL to launch sales of popular redesigned propeller boss cap fins

Mitsui OSK Lines (MOL), Japan’s largest shipowner, will start selling an upgraded version of its popular energy-saving propeller boss cap fins (PBCFs). MOL has sold more than 3,100 PBCFs to shipowners all over the world to date.

“The new design enhances propeller thrust and reduces torque thanks to refinements in fin shape and height,” MOL stated in a release today. Tests of the new type PBCF on vessels in service confirmed an energy savings of around 5% compared to sister vessels not equipped with PBCF. The previous design showed an estimated 3% energy savings. The new PBCF design has already been patented around the world.

The PBCF was also selected as a vessel noise-reduction technology by the Port of Vancouver.

MOL said today it will develop the environment and emission-free businesses into one of its future core operations.
