The 58,500 DWT Supramax bulk carriers Elsabeth C and Mirela showcase their shiny new MAN Alpha Kappel mounted pitch propellers, marking the primary industrial software for the brand new MAN Diesel & Turbo’s propellers.

The ships are owned by Frontmarine Co., an affiliated and managed firm of Lemissoler Navigation. Lemissoler experiences that sea trials have proven that the brand new propellers, mixed with the vessels distinctive design and contours and silyl acrylate antifouling paint, helped the vessels devour a mean 23 mtns per day at a pace of about 14.2 knots in ballast circumstances through the sea trials.

According MAN, the Kappel propeller blades are designed for elevated gas effectivity and noise discount and characterised by a curved tip ‘fin’ that minimizes the water circulate over the tip of the propeller blade, leading to a better whole effectivity in comparison with standard propellers.

Thomas Leander, Head of Propulsion for MAN PrimeServ Four-Stroke in Denmark, stated: “A key point during the design stage was to address the problem experienced by similar vessels that experience an overly-small light running margin (LRM). Therefore, MAN Diesel & Turbo recently introduced new light running margins for all FP propellers and two-stroke engines of 4-10%. Furthermore, the propeller layout for these 58,500-dwt vessels is 3-4% higher than normally applied to these vessel types. In doing so, MAN Diesel & Turbo has managed to ensure safe and reliable operation, while improving the vessel’s efficiency and maneuverability during its entire lifetime.”

The Elsabeth C and Mirela had been constructed by New Times Shipbuilding Co’s Jiangsu, China, shipyard and are the primary of eight sister ships being constructed for Frontmarine, all that includes single MAN B&W 5S60ME-C8.2 engines with an SMCR 8050 kW @ 89 rpm.
