MAN Diesel & Turbo’s Propeller & Aft Ship organisation has won an order to[ds_preview] retrofit and upgrade a series of eleven 37,500 dwt vessels from the Odfjell chemical tanker fleet. The vessels are of the Kværner Class and are due to dock during 2015–17, at which time the upgrades will be implemented. The first vessel to be upgraded is the »Bow Clipper« in August 2015. Each vessel has an MAN B&W two-stroke engine powering a four-bladed controllable-pitch propeller and a PTO-driven shaft alternator.
