Japanese shipping company Mitsui OSK Lines (MOL) said on 20 May that its subsidiary has succeeded in clinching orders of its energy-saving propeller boss cap fins (PBCFs) for as many as 3,000 vessels.
The PBCF is installed at the propeller of the vessel to reduce energy consumption. It eliminates the occurrence of the hub vortex behind the propeller.
According to MOL, this enables bunker savings of 3-5%, resulting in lower carbon dioxide emissions. For example, more than 9,000 tonnes of carbon dioxide emission per year are reduced for ultra-large container ships.
The equipment is easy to install and does not require maintenance after its instalment.
MOL began researching and developing the equipment with two other Japanese companies in 1986.
However, the product began seeing increased sales only in recent years when there was growing worldwide concerns over environmental protection and the upsurge in bunker prices.
