Update hipowners and operators are looking to pick the “low-hanging fruit” that will enable them to save fuel and cut their greenhouse gas emissions. That is the impetus behind the joint decision by shipping company Concordia Maritime and French energy company Total to install MAN Diesel’s new Variable Tubine Area (VTA) technology turbochargers aboard a new tanker. The turbochargers with VTA technology will equip the MAN B&W lowspeed diesel engines aboard the new P-MAX tanker Stena Progress, which will be delivered June 2009. On the basis of earlier test trials onboard the shallow-draft Stena President, Concordia and Total expect to reduce fuel consumption by around 2-3% with parallel reductions in exhaust emissions. “We are always interested in new energy saving technologies,” noted Concordia Maritime president Hans Norén. “It has been tested onboard our ship Stena President with very positive results and, as a consequence, we and our customer Total have decided to INLAND • COASTAL • OFFSHORE • DEEPSEA Turbochargers to cut tanker’s fuel consumption S install VTA turbochargers onboard the Stena Progress.” Stena Progress is a 65,200-dwt shallow draft ice class P-MAX tanker under construction at the Brodosplit shipyard in Split, Croatia. It is due for delivery in June 2009 and will be chartered to Total for five years. MAN Diesel type TCA55V turbochargers—the “V” suffix denotes the inclusion of variable turbine area technology—will be used on the two MAN B&W six-cylinder 6S46MC-C low speed main engines aboard the Stena The MAN Diesel VTA turbocharger Progress and other P-MAXs. system was tested aboard the “These tankers’ routes include arctic waters, which means varying tanker Stena President ice conditions and thus highly variable load profiles,” stated Jacob Norrby, naval architect, at Stena Teknik. “By and, most importantly, the 2 to 3% reducallowing charge air delivery to be optimized tion in fuel consumption.
