MAN Diesel & Turbo (MAN) Friday announced it has won an order from Odfjell SE (Odfjell) to upgrade eleven 37,500 dwt chemical tankers with its Kappel technology to improve efficiency and lower the shippers bunker bill.

The upgrade package includes MAN's Kappel propeller blades, fairing cone, and a pre-fabricated rudder bulb kit, and MAN says that combined with the tankers' new service speed it will lower bunker consumption, increase propulsion efficiency, and reduce vessel emission. 

"It's a very exciting project and we are proud to be part of it," said Kjartan Ross, Business Development Manager of MAN's Propeller & Aft Ship organisation.

"With the long lifetime expectancy of Odfjell's high value, quality vessels, this upgrade investment is straightforward and very attractive," he added.

The upgrade components are custom-designed to fit the tankers' hull and rudder designs. 

Odfjell's chemical tankers are of the Kværner Class, and are outfitted with MAN B&W two-stroke engines that power controllable four-bladed pitch propeller and a PTO-driven shaft alternator.

MAN noted the rates of savings achieved by the planned upgrade were verified in preliminary results through testing conducted by Norwegian Marine Technology Research Institute (MARINTEK).

Looking ahead, Ross noted, "With our new design possibilities, we are furthermore looking forward to offering this fuel-saving concept to other fleets with similar operational patterns."

Earlier this year, MAN successfully demonstrated its ME-LGI two-stroke methanol engine, and has received several orders so far.
