Tanker Gets Kappel Propeller Retrofit
MAN Diesel & Turbo’s PrimeServ retrofit team signed an agreement with Great Eastern Shipping Company (GESCO) of Mumbai, India regarding a propeller retrofit upgrade for their M/T Jag Lavanya – a Samsung-built 105,000 DWT crude oil carrier from 2004.
MAN Diesel & Turbo announced a strategic focus that added the Kappel design to its fixed-pitch propeller portfolio, both for newbuildings and as a retrofit solution to vessels already in service. After a decade’s cooperation with inventor J.J. Kappel, MAN Diesel & Turbo took over the Kappel design business in 2012 and has since developed it further in terms of fixed-pitch propellers. The fuel savings and performance characteristics for controllable-pitch propellers, featuring the unique Kappel blade design, have been well documented over the last five years.
Retrofit calculations on different fixed-pitch propellers evaluated for the M/T Jag Lavanya show the superiority of the Kappel design. Christian Wollerup Sørensen, Sales Manager, MAN Diesel & Turbo said, “With this vessel’s speed and operating profile, the new Kappel propeller will deliver a fuel saving of 4% together with a reduced level of pressure impulses to hull – and without adding any other, efficiency-improving devices.”
The four-bladed, 6.9 meter Kappel propeller for the Jag Lavanya will be delivered from China in January 2014.
