Wärtsilä Launches Aframax with Built-in Scrubber
Wärtsilä Corporation's Ship Design division says it has developed a new Aframax tanker design that includes a built-in exhaust gas scrubber that can meet a 0.1 percent sulfur limit even using heavy fuel oil with a 3.5 percent content.
"The new realities of the shipping industry call for higher fuel efficiency, lower operating costs, and better environmental performance," said Riku-Pekka Hägg, vice president of Wärtsilä Ship Design.
"The new Wärtsilä Aframax tanker design meets all these criteria, and we are proud to offer this segment the combination of state-of-the-art design and superb propulsion machinery that can produce meaningful savings."
The double hull, single screw crude oil tanker features an optimised hull form to address pressure distribution and accommodate various operational draughts and weather conditions.
The two-stroke Wärtsilä X62 main engine also promotes efficiency with a slim aft body design, extra long stroke and low rpm, and compared with main engines available now it offers fuel savings of 7 percent, and the ability to reach the same vessel speed with six, rather than seven, cylinders.
A selective catalytic reduction system improves combustion efficiency and reduces nitrogen oxides emissions by more than 90 percent.
As ship owners seek ways to adjust to new emission regulations, Wärtsilä promises its scrubbers provide a viable alternative to switching to lower-sulfur fuels.
