Swappable blades with modular CoB

摘要

Propulsion specialist Teignbridge has launched a new modular propeller concept, designed to enable users to swap individual blades instead of having to remove and repair the entire propeller.The gist of the company's 'Clamp-on Blade (CoB) concept is that operators carry a stock of spare single propeller blades and simply remove and replace damaged blades as they sail - thus avoiding the costs associated with unscheduled spells in dry dock and vessel downtime. The CoB propeller's blades can be mailed by box or standard container.Teignbridge says: "Many vessels will be able to carry spare blades and, if required, trim by the head to make the propeller accessible and replace the blades using a barge and crane, rather than having to use a dry dock. Vessel owners only need to carry one or two spare blades, rather than a spare propeller, saving space and cost."
